many APs are fired.
the membrane depolarizes.
When X fires 10 times and Y fires 10 times, the result will be a subthreshold summation.
Subthreshold summation happens when two or more presynaptic inputs that are sub-threshold (i.e., they cannot create an action potential) combine their effects on the postsynaptic neuron.
Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.
When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).
Therefore, when X fires 10 times and Y fires 10 times, the postsynaptic neuron will experience subthreshold summation and no action potential will be fired.

A student is writing a description of how cyclic factors can combine to create extreme seasons. Complete the student's description. Cyclic factors can greatly influence Earth's climate. For example, more extreme seasons could be caused by (blank) tilt in Earth's rotational axis. Similarly, summer occurring at (blank) along a (blank) eccentric orbit path would make for an extreme summer.
The cyclic factors that can combine to create extreme seasons are called Milankovitch cycles, and involve several factors:
• Axial tilt or obliquity (how inclined or tilted is the Earth's rotational axis)
,• Axial precession (direction of the Eart's rotation)
,• Apsidal precession (the orientation of the Earth's orbit)
,• Orbital eccentricity (how elongated is the orbit)
,• Orbital inclination
We see that the sentence mentions them, let's use the options provided (perihelion, more, an increased) to complete the sentence.
For example, more extreme seasons could be caused by an increased tilt on Earth's rotational axis. Similarly, summer occurring at perihelion (closest to the sun) along a more eccentric orbit path would make for an extreme summer.

While mapping the motor cortex, researchers Foerster and Penfield found that body areas requiring the greatest control occupied the greatest amount of cortical space
The majority of the afferent fibres that enter each region of the cerebral cortex come from a single thalamic projection nucleus. This thalamocortical projection is topographically organised so that discrete thalamic volumes project to discrete fields in the cortex, while continuous thalamic volumes project to a continuous region in the cortex. A point-to-point projection could be thought of in this respect, however this oversimplification ignores the mutual overlap of thalamic fibres inside their "modular" cortical arborization zones . Because the cerebral cortex is a two-dimensional surface and the thalamus is a three-dimensional body, the topographical depiction of the thalamic projection nuclei over the cerebral cortex is a topological problem.
Hence, Foerster and Penfield found that body areas requiring the greatest control occupied the greatest amount of cortical space.

2. The number of grizzly bear deaths in Alberta from 1976 to 1988 was estimated to be 581. Only 281 deaths were recorded from 1988 to 2000. How does this information affect the prediction you made in question 1? Explain your answer.
The data shows a significant decrease in grizzly bear deaths from 581 in the earlier period to 281 in the later period.
The information about grizzly bear deaths in Alberta from 1976 to 1988 and from 1988 to 2000 affects the prediction made in question 1 by providing additional data points and context.This decrease in grizzly bear deaths suggests a possible declining trend in the population. If the overall trend continues, it is reasonable to assume that the population has decreased further since 2000.
Taking this new information into account, the prediction made in question 1 should be revised. Instead of assuming a stable population or a slight increase, it would be more accurate to predict a decline in the grizzly bear population in Alberta. However, it is important to note that additional factors, such as conservation efforts or changes in habitat, should also be considered to gain a comprehensive understanding of the population dynamics.

The answer is YESIn addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes.
What is a Eukaryotic cell?
A eukaryotic cell is one of two different types of cells. Organisms that are based on the eukaryotic cell are called “eukaryotes” and include plants, animals, fungi, and protists.
What is Mitochondria?
The mitochondrion (plural mitochondria) is a membrane-bound organelle found in the cytoplasm of eukaryotic cells. It is the power house of the cell; it is responsible for cellular respiration and production of (most) ATP in the cell. Each cell can have from one to thousands of mitochondria. Mitochondria also contain extranuclear DNA that encodes a number of rRNAs, tRNAs, and proteins.
Describe how the components of a meal containing fried fish and toast bread will be processed as they move through the digestive system of man
Answer:
Explanation:
When a meal containing fried fish and toast bread is consumed, it goes through a series of processes in the digestive system of a human. Here's a general description of how the components are processed:
1. Mouth: The process of digestion begins in the mouth. Chewing breaks down the toast bread and fish into smaller pieces, while saliva mixes with the food to start the breakdown of carbohydrates.
2. Esophagus: The chewed food, now called a bolus, is swallowed and travels down the esophagus through peristaltic contractions. The esophagus carries the food to the stomach.
3. Stomach: The stomach is responsible for further mechanical and chemical digestion. It mixes the food with stomach acid and digestive enzymes to break down proteins. The fried fish is broken down into smaller pieces through mechanical churning.
4. Small Intestine: The partially digested food leaves the stomach and enters the small intestine. Here, bile from the liver and enzymes from the pancreas break down fats, while other enzymes continue the breakdown of proteins and carbohydrates. Nutrient absorption occurs through the walls of the small intestine and is facilitated by small finger-like projections called villi.
5. Large Intestine: Any remaining undigested food, as well as water and electrolytes, pass into the large intestine. The large intestine absorbs water and electrolytes while forming waste material known as feces.
6. Rectum and Anus: The feces are stored in the rectum until elimination through the anus occurs during a bowel movement.
Throughout this process, various digestive enzymes and gastric juices are secreted at different stages to facilitate the breakdown and absorption of nutrients. The fried fish and toast bread are broken down into smaller molecules, such as proteins, carbohydrates, and fats, which are then absorbed into the bloodstream to provide energy and nourishment for the body.

Residual parent material refers to the *weathered rock* and *soil* that remains in its place of origin, while *transported parent material* is material that has been carried and deposited by natural agents such as water, wind, or glaciers.
The impact of these different types of parent material on *soil formation* can be significant. Residual parent material tends to contribute to the formation of soils with characteristics similar to the parent rock. The weathering process breaks down the rock into smaller particles, allowing for the development of soil horizons and the release of minerals that influence soil fertility. In contrast, transported parent material can introduce a diverse range of materials to a given area, leading to variations in soil composition, texture, and fertility. The transportation process can mix different types of sediment, resulting in the formation of heterogeneous soils with varying properties.
Residual parent material is the rock and soil that is still located in its original location and is weathered. Transported parent material is material that is carried and deposited by natural agents such as water, wind, or glaciers. The effect of these different types of parent material on soil formation can be significant.
Residual parent material usually contributes to the development of soils with qualities similar to the parent rock. The breakdown of rock into smaller particles through weathering enables the formation of soil horizons and the release of minerals that influence soil fertility.
The physical and chemical characteristics of soils derived from this form of parent material are often similar and homogeneous, allowing for predictable fertility and properties. Transported parent material, on the other hand, can introduce a diverse range of materials to a given area, resulting in variations in soil composition, texture, and fertility.
The transportation process can blend different types of sediment, resulting in the formation of heterogeneous soils with different characteristics. Transported parent material can also be exposed to weathering processes, altering its original composition and resulting in soils with varying degrees of fertility.
While transported parent material can increase the diversity of soil properties in an area, it can also make it difficult to predict soil characteristics, particularly in areas where different types of sediment have been deposited. The relationship between parent material and soil development is complex, with both the initial characteristics of the material and the surrounding environment influencing soil properties.
In general, residual parent material contributes to the development of homogeneous soils with predictable properties, while transported parent material can result in more diverse and heterogeneous soils.

Describe three different strategies used by three different animals to thermoregulate. If you see a snake coiled up in a sunny patch of grass, what can you probably conclude about the type of thermoregulator it is. Why?
The brain and spinal cord are part of the central nervous system.
The electrical charges that act as nervous signals are called action potentials or nerve impulses.
Jellyfish do not have a brain. Instead, their nervous system is called a nerve net.
After nervous systems began to develop in bilaterally symmetric animals, some developed ventral nerve cords, while chordates developed dorsal nerve cords.
Skeletons that allow for movement by using muscles and squeezing liquid to change the body shape are called hydrostatic skeletons.
Exoskeletons do not grow with arthropods, and so occasionally must be shed and regrown from chitin.
Muscles move endo- and exoskeletons by contracting and relaxing.
Fertilization is the joining of two gametes called sperm and egg.
A fish that lays her eggs in a cluster is initiating cluster or mass fertilization.
Amniotic eggs are an adaptation by reptiles to allow for reproduction and embryo development on land.
Describe three different strategies used by three different animals to thermoregulate.
Elephants: Elephants thermoregulate by using their large ears as cooling devices. They flap their ears to increase surface area and enhance heat loss through evaporative cooling.Desert Lizards: Desert lizards employ behavioral thermoregulation by basking in the sun to absorb heat and warming their bodies. They also retreat to shade or burrows to avoid excessive heat when needed.Penguins: Penguins have a unique thermoregulation strategy. They huddle together in large groups to conserve body heat and shield themselves from the cold Antarctic winds, effectively reducing heat loss and maintaining body temperature.If you see a snake coiled up in a sunny patch of grass, what can you probably conclude about the type of thermoregulator it is. Why?
If you see a snake coiled up in a sunny patch of grass, you can probably conclude that the snake is an ectotherm. Ectotherms rely on external heat sources, such as the sun, to regulate their body temperature. By basking in the sun, the snake absorbs heat, which helps raise its body temperature to a suitable level for proper physiological functioning.
Answer:
1. central
2. action potential
3. nerve net
4. dorsal
5. hydrostatic
6. Exoskeletons
7. contraction/contracting
8. Fertilization
9. external fertilization
10. Eggs
11. Animals with fur thermoregulate by panting. Winged birds will flap against their mouths/heads to dissipate heat. Humans will produce sweat to evaporatively cool. Polar bears have developed blubber. Bears drop body temperatures during hibernation.
12. Seeing a snake using the warmth of the sun leads us to conclude that it is likely a thermo conformer that cannot produce its own body heat.

Explain the limitation binomial nominclature (15 marks)
Answer:
- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.
What is binomial nomenclature?
Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.
Binomial Nomenclature also known as the binary nomenclature.
It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.
The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.
Both of this term is written in italic and the genus name is capitalized.
Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.
Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.
These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.
Summary of the limitation binomial nominclature:
- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.
