The sarcomere is the muscle unit of contraction. Option C) sarcomere size is relatively constant in vertebrates. as a result, mouse and elephant sarcomeres will likely be equal in size.

When talking about a sarcomere we are referring to the contractile unit of the contractile apparatus -muscle-.

In the sarcomere, we can identify the following components,

When the muscle contracts, the muscular fiber gets shorter and thicker due to the reduction in the sarcomere length.

The H line and the I band get shorter. The Z lines get closer to the A band, meaning they get closer to one another. The A band keeps constant in length.

The sarcomere length is about 2 mm during a contraction when actin filaments are completely superposed over the myosin filaments. This length is about the same in all vertebrates.

The correct option is C) sarcomere size is relatively constant in vertebrates. As a result, mouse and elephant sarcomeres will likely be equal in size.

The reason why the age is of high importance is because it determines during what time the fossil lived and how it has evolved.

Its chromosomal number of 30 and indeed the diploid number if 60 are shared by Diana and green monkeys. According to some kind of haploid number of 32, brown woolly monkeys have a diploid number of 64.

Definition. Mammalian somatic cells contains 46 chromosomes, 22 pairs of autosomes, with two sets of sex chromosomes, making them diploid. A cell that seems to have each chromosome in two copies is said to be diploid.

During the process of sex maturation, diploid cells go through meiosis, producing haploid gametes. Haploidy therefore represents the limit of cell growth and is restricted to the post-meiotic gamete stage of germline development, whereas diploidy ensures pluripotency, cell proliferation, and other activities.

Answer: Biomagnification refers to the process by which the concentration of a contaminant increases as you move to higher trophic levels in a food chain or food web. In other words, as organisms consume other organisms, the contaminants present in the prey accumulate and become more concentrated in the bodies of the predators.

To understand this process, let's consider an example involving a water ecosystem. Suppose a pollutant is released into the water, such as a pesticide or heavy metal. The primary producers, such as algae or aquatic plants, absorb small amounts of the contaminant from the water. As herbivorous organisms consume these primary producers, they ingest the contaminants along with their food.

Since the contaminant is not easily broken down or eliminated from the organisms' bodies, it accumulates over time. As a result, the concentration of the contaminant becomes higher in the herbivores than in the primary producers. Now, when carnivorous organisms consume the herbivores, they not only accumulate the contaminant from their own food but also from all the prey they have consumed. This leads to an even higher concentration of the contaminant in the carnivores.

Therefore, biomagnification describes the phenomenon where the concentration of a contaminant increases significantly as you move up the food chain or trophic levels. The highest concentration of contaminants is often found in top predators, such as large fish, birds of prey, or mammals, which can have adverse effects on their health and reproductive capabilities.

It's important to note that biomagnification primarily occurs for persistent and non-biodegradable contaminants that cannot be easily metabolized or excreted by organisms. These contaminants are often lipophilic (fat-soluble), which allows them to accumulate in fatty tissues and remain in the organism's body for long periods, leading to biomagnification.

Explanation:

Predicted phenotypes are:

Some offspring will have a black coat color (c^b c or c^b c^b)

Some offspring will have an agouti coat color (b c or b c^b)

The coat color in mice depends on three alleles: c^b, c, and b.

In this case, the scientist crosses a black mouse (c^b b) with an agouti mouse (cc^b b).

To determine the predicted phenotypes of their offspring, we need to consider the possible combinations of alleles.

The alleles of the black mouse are c^b and b, while the alleles of the agouti mouse are c and c^b.

When we cross these mice, we can combine the alleles in the following ways:

- c^b from the black mouse with c from the agouti mouse: c^b c
- c^b from the black mouse with c^b from the agouti mouse: c^b c^b
- b from the black mouse with c from the agouti mouse: b c
- b from the black mouse with c^b from the agouti mouse: b c^b

Based on these combinations, the predicted phenotypes of their offspring would be:
- Some offspring will have a black coat color (c^b c or c^b c^b)
- Some offspring will have an agouti coat color (b c or b c^b)

Therefore, the predicted phenotypes of their offspring are a mix of black and agouti coat colors.

Answer:  The answers are as follows:

Where does the Calvin cycle occur and does it need light?

Unlike the light reactions, which take place in the thylakoid membrane, the reactions of the Calvin cycle take place in the stroma (the inner space of chloroplasts).

Where does photosynthesis get its energy to start?

The whole process of photosynthesis is a transfer of energy from the Sun to a plant. In each sugar molecule created, there is a little bit of energy from the Sun, which the plant can either use or store for later.

What is the chemical equation for cellular respiration?

The equation for cellular respiration is: C6H12O6 + 6O2 → 6CO2 + 6H20 + energy (Glucose + Oxygen yields Carbon Dioxide + Water + Energy) You may notice that the equation for cellular respiration is the opposite of the equation for photosynthesis.

What are the reactants and products of lactic acid fermentation? What is the basic equation?

The simple equation for lactic acid fermentation is glucose ---glycolysis---> 2 pyruvate ---fermentation--> 2 lactic acid. That is to say that glucose is broken down by glycolysis into 2 pyruvates, and then those pyruvates are fermented to produce 2 lactic acid molecules.

How is citric acid formed in the Krebs cycle?

The Krebs cycle itself actually begins when acetyl-CoA combines with a four-carbon molecule called OAA (oxaloacetate) (see Figure above). This produces citric acid, which has six carbon atoms. This is why the Krebs cycle is also called the citric acid cycle.

What are the steps in cellular respiration?

There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation. Glycolysis takes place in the cytosol, the citric acid cycle occurs in the mitochondrial matrix, and oxidative phosphorylation occurs on the inner mitochondrial membrane.

The energy for glycolysis comes from which molecule?

Glycolysis is a series of reactions that extract energy from glucose by splitting it into two three-carbon molecules called pyruvates.

During which step of cellular respiration is carbon dioxide released?

The stage of cellular respiration in which carbon dioxide release takes place is the citric acid cycle. Aerobic cellular respiration has three steps, glycolysis, the citric acid cycle, and the electron transport chain.

What are the products and reactants of cellular respiration?

During cellular respiration, the reactants—glucose (sugar) and oxygen—combine together to form new products: carbon dioxide molecules and water molecules.

Explain how ectotherms and endotherms regulate their body temperature.

Endotherms use internally generated heat to maintain body temperature. Their body temperature tends to stay steady regardless of the environment. Ectotherms depend mainly on external heat sources and their body temperature changes with the temperature of the environment.

How do humans control their body temperature using ATP?

The muscle contractions of shivering release heat while using ATP. The brain also triggers the thyroid gland in the endocrine system to release thyroid hormone, which increases metabolic activity and heat production in cells throughout the body.

In 3-5 sentences explain how the environment would affect the photosynthetic process of a rainforest plant versus a desert plant. Consider the amount of sunlight and water available in each environment.

The environmental factors that would be more important to a rainforest plant would be sunlight and carbon dioxide. This is because rainforests are shadier and there would be less sunlight for the plant to get, which could cause the plants to get taller in order to reach the sunlight. However, in the desert, the plants would be more dependent on water and carbon dioxide.

Dragonflies are flying insects. In the summer, dragonflies can be seen perched on tree branches in an obelisk pose (i.e., a handstand position with the tip of their abdomen pointing upward). In 3–5 sentences, describe how dragonflies might control their body temperature and give reasons for why they might perch in this pose.

The powered flight regulates body temperature and obelisk posture helps to prevent overheating due to the sun. Dragonflies control their body temperature with the help of controlling metabolic heat production by alternately using powered flight as well as controlling heat loss by changing the circulation between the thorax and abdomen. The dragonflies raised their abdomen until its tip pointed to the sun in order to minimize the surface area exposed to solar radiation so that powered flight regulates body temperature and obelisk posture helps to prevent overheating due to the sun.

1. The Calvin cycle is the light-independent (does not need light) step of photosynthesis and happens in the stroma.

2. Light

3. C6H12O6 + 6O2 → 6H2O + 6CO2 + Energy

4. Pyruvic acid + NADH → Lactic acid + NAD+

5. Glycolysis - Krebs Cycle - Electron Transport Chain

6. ATP

7. Reactants are glucose and oxygen, products are carbon dioxide and water with energy in the form of ATP

8. Ectotherms cannot insulate (stop heat loss from) their bodies and can only control their body temperature by choice.

9. shivering

10. Environmental challenges the would affect a rainforest plant would be climate change, and drought. In the rainforest, it may become harder and harder for a plant to survive if it cannot adapt to the rapid changing of the climate, with temperatures becoming rapidly hotter and dropping just as fast, while the total lack of water would take away one of the reactants needed for photosynthesis, further lowering a plants chances for survival.

Environmental challenges that would affect a rainforest plant would be erosion, and climate change. Deserts are very sensitive when it comes to external changes to its environment, and if they already have very little rainfall, climate change could destroy plants as they would have nothing of the little resources they have to survive on. Erosion can destroy desert soil, and as it already takes a massive amount of time to grow plants, the total lack of soil could stop plant growth altogether.

11. Dragonflies are exothermic which means their bodies are warmed by their environment. They cannot easily warm their bodies themselves, so they stay warm by traveling to areas of warmth which might give reason as to why they perch in the obelisk pose. By flying, they can help regulate warmth throughout their bodies, and the obelisk posture on tree branches can ensure that they do not overheat and maintain proper body temperature.

The enzyme represented in the graphs works best at a temperature of 50°C and a pH of 12.

The graph indicates that there is a significant increase in enzyme activity at a temperature of 50°C and a pH of 12. This suggests that the enzyme's optimal conditions for activity are a high temperature and an alkaline pH. Option B, "This enzyme works best at a temperature of 50°C and a pH of 12," aligns with this observation.

Enzymes are highly sensitive to changes in temperature and pH, and their activity can be influenced by these factors. In this case, the graph shows a peak in enzyme activity at 50°C, indicating that the enzyme functions most efficiently at this temperature. Additionally, the graph shows another peak at a pH of 12, indicating that the enzyme's activity is highest under alkaline conditions. This supports the claim that the enzyme works best at a temperature of 50°C and a pH of 12. The other options can be ruled out based on the evidence provided by the graph, which clearly demonstrates the influence of temperature and pH on the enzyme's activity.

Answer:

Rats with ventromedial lesions should begin overeating; rats with lateral lesions should stop eating

Explanation:

The feeling of hunger stimulates a desire to eat.

The lateral hypothalamus is responsible for making an organism hunger and craves for food upon receiving any stimulation or signal that causes hunger.

A damaged to the lateral hypothalamus would mean the organism would not be able to sense hunger and thus, there would be no desire to eat. Hence, the rats with lateral lesions should stop eating.

On the other hand, the ventromedial hypothalamus is responsible for quenching hunger and signaling to the organism that it is full, hence, it would stop eating. However, when the ventromedial hypothalamus is damaged, the organism would not be able to tell when to stop eating. Hence, rats with ventromedial lesions should begin overeating.
