F2) Genotypes:

   Phenotypes:

Solution:

Mendel's law of independent assortment states that the alleles of two or more different genes get sorted into gametes independently of one another.

So, we can conclude that the correct answer is:

B) Gregor Mendel

Answer:

The F2 ratio would be: 1:0:0:0 dominant W and dominant A individuals : 1:1:0:0 dominant W and recessive a individuals : 1:1:0:0 recessive w and dominant A individuals : 1:1:0:0 recessive w and recessive a individuals

Explanation:

All the progeny resulting from this cross will be of an identical genotype (WWwwAAaa) since the parent genotype is homozygous dominant being crossed with homozygous recessive. The phenotypic ratio in this case is 1:0:0:0, indicating that all offspring express the dominant trait and are carriers of the recessive trait.

The purpose of Mendel's experiments with dihybrid crosses was to determine whether two traits affect the inheritance of each other. Therefore, the correct answer is D. Mendel wanted to understand how different traits, controlled by separate genes, are inherited and whether they show any relationship or influence each other in the inheritance patterns. This was done by crossing pea plants that differed in two traits, such as seed color and seed texture, and observing the patterns of inheritance in the offspring.

D. A waxy coating of the bundle sheath

Explanation:

C3 plants are plant that make use of Calvin cycle for synthesising their food while C4 plants makes use of Calvin cycle along side a 4 carbon compound that help store carbondioxide.

The C4 plant is unique because it has both mesophyll cell and bundle sheath unlike C3 plant that has only the mesophyll cell. The bundle sheath is where the 4 carbon compound that ferried carbondioxide is first stored before in form of oxaloacetate before broken down cell into pyruvate and carbondioxide and now proceed into the Calvin cycle for the formation of sugar in the bundle sheat.

The bundle sheat and mesophyll cell help separate when carbondioxide is ferried in and when it is used up for sugar formation in C4 plants.

Answer:

It is a group designed to not be affected by any variables and to be used as a comparison to the other groups. It helps increase the reliability of your results, as it shows your independent variable is what made something happen in your experiment.

Based on the carbon cycle simulation model, what happens when you increase plant biomass is that atmospheric CO2 decreases. because in the cellular respiration of the plants they will consume more carbon.

Plants, through the process of respiration, also absorb carbon dioxide and release oxygen unlike animals. The carbon deposited in the soil can undergo alterations, turning into fossil fuels such as oil and natural gas, in addition to forming diamonds, graphite and coal mines, among others.

With this information, we can conclude that based on the carbon cycle simulation model, what happens when you increase plant biomass is that atmospheric CO2 decreases. because in the cellular respiration of the plants they will consume more carbon.

Answer:

the condensation of water vapor as it touches a colder surface.

Explanation:

1. Over millions of years, a water molecule can be transferred and transformed through the water cycle by processes such as evaporation, condensation, precipitation, runoff, infiltration, groundwater flow, and ocean currents.

2. After a refreshing shower, steam fills the bathroom, causing warm, moist air to rise and condense on the cooler bathroom mirror.

As droplets form, a journey begins for a water molecule named Wally. Wally, part of a droplet, evaporates due to the bathroom's warmth, becoming water vapor. Riding air currents, Wally rises to the atmosphere, joining clouds in a process known as condensation. United with other droplets, Wally experiences coalescence and becomes a raindrop, falling as precipitation.

Upon landing in a lush garden, Wally is absorbed by plant roots in a process called infiltration, fueling photosynthesis. A friendly earthworm, part of the living organism realm, aids infiltration by burrowing, allowing water to seep deeper into the ground. Underground, Wally joins groundwater, becoming part of an aquifer.

Time passes, and Wally encounters a geological shift, emerging as a freshwater spring. The sun's energy fuels evaporation from the spring's surface, and Wally returns to the atmosphere as water vapor. Caught in a wind pattern, Wally journeys afar, reaching an ocean. Guided by ocean currents, Wally participates in thermohaline circulation, absorbing heat and releasing energy into the atmosphere.

In a distant land, Wally is lifted into a cloud, cooled, and once again condenses. Falling as rain over a river, Wally reunites with a bustling ecosystem. As a river flows to the ocean, Wally experiences transportation, and the water body teems with life. Finally, guided by gravity, Wally reaches the ocean, where the cycle continues.

In this cyclical adventure, Wally undergoes four state changes (evaporation, condensation, precipitation, and infiltration), encounters diverse processes, such as evaporation, condensation, infiltration, and ocean currents, and interacts with living organisms, like plants and earthworms. Energy flows from the sun, driving these processes and sustaining the dynamic water cycle.

Answer:

C. It will stay the same

Explanation:

Let's say the population is 7

Then let's say 4 more are born, and since the number of births and deaths are the same then the number of deaths must be 4.

Since the number of births is positive and the number of deaths are negative then they cancel out and the population number stays the same.

Therefore C is correct.

If the number of birth in a population is the same number of deaths in a population, the growth of the population will stay the same. Thus, the correct option for this question is C.

A Population may be defined as a group of individuals belonging to the same species living in the same area at a particular time.

The characteristics of the population like size, birth rate, death rate, population dispersion, age distribution, etc. cannot be applied on the individual level. But these factors can be significantly represented on the graph and hence, they are known as demographic factors.

The growth rate of the population can be measured by two factors such as birth rate and death rate. When the birth rate is greater than the death rate, the growth of the population will increase. But when the birth rate is lower than the death rate, the growth of the population will decrease.

Therefore, if the number of birth in a population is the same number of deaths in a population, the growth of the population will stay the same. Thus, the correct option for this question is C.

Best description of the roots of the equation x² - 4x + 4 = 0 is that it has one real double root.

In mathematics, discriminant of a polynomial is a quantity that depends on coefficients and allows deducing some properties of roots without computing them.

Discriminant is b² - 4ac for a quadratic equation in the form ax² + bx + c = 0. For the equation x² - 4x + 4 = 0, a = 1, b = -4, and c = 4, so the discriminant is: b²-4ac = (-4)²-4(1)(4)

=16 - 16 = 0.

As the discriminant is equal to 0,  quadratic equation has only one real root. This root is a double root, meaning that it is same value twice. In this case, quadratic equation x² - 4x + 4 = 0 can be factored as (x - 2)² = 0, so  only real root is x = 2, and it has a multiplicity of 2.

Therefore, the best description of the roots of the equation x² - 4x + 4 = 0 is that it has one real double root.

A tiny electric message moves through a long part of a brain cell called the axon. When a message goes to the end of a nerve, it sends chemicals called neurotransmitters. These substances move through a tiny gap and attach to special parts of another nerve cell's outer covering.

Messages called impulses are sent from one nerve cell to another through a connection called a synapse. This process is called synaptic transmission. Synapses are connections between nerve cells or between nerve cells and other cells, like muscles or glands.

The neuron sending the signal is called the presynaptic neuron. When a signal travels down a nerve cell, it causes little sacs called vesicles to release chemicals called neurotransmitters.

The basic processes involved in the transmission of information from the beginning of one neuron to the beginning of the next neuron are as mentioned below-

The types of ions within and outside the neuron's cell walls are out of equilibrium while the neuron is at rest, which means it is not actively transmitting a signal. Incoming signals from other neurons enter at the dendrites and move across the cell body to the axon when a neuron receives input from those other neurons.

The inside of the cell may become more positively or negatively affected by these signals. The neuron may fire an action potential if the incoming signals increase the neuron's internal potential. If this occurs, the neuron may achieve its threshold of excitation.

Neurotransmitters are released into the synapses when the action potential reaches the axon bulb of the presynaptic (sending) neuron. In the fluid-filled synapse, the neurotransmitter molecules float. Several of them will quickly move across the synapse and make contact with the tulip-shaped receptor sites arranged in a straight line on the dendrites of the postsynaptic (receiving) neuron.

Neurons are used to transmit information. Through electrical impulses and chemical signals, they communicate both inside the brain and between the brain and the rest of the nervous system.
