1. The right answer is It helps keep the organelles in place and directs their movement as needed.

The cytoskeleton provides a certain rigidity to the cell and serves for the fixation of organelles (equivalents for the organ cell for an organism).

The cytoskeleton is constantly reorganized and thus governs the internal movements (displacement of chromosomes for example) and the deformations of its membrane (production of protuberances, invaginations, sites of adhesions ...).


2. The right answer is The cell's energy level will diminish as the enzyme decreases.

Cellular respiration is the set of biochemical reactions leading to the formation of ATP,  energy source of the cell.

This mechanism consumes oxygen and creates carbon dioxide as waste. That's why we talk about cellular respiration.

It is the three-step set, glycolysis, the Krebs cycle and the electron transport chain related to oxidative phosphorylation, which lead to the formation of ATP. If these reactions are not assured by lack of enzymes then there will be no production of ATP (energy production).


3. The right answer is Whales are able to conserve oxygen better than humans.

As the duration of the dive of some whale species can reach more than one hour, they use other means to breathe. In vertebrates, myoglobin, a protein, transports and stores oxygen in muscle tissue. It works like hemoglobin that carries oxygen in red blood cells. It is also myoglobin concentration very strong that makes their flesh bright red color, almost black. Thus, whales use the oxygen stored in the muscles to dive for long periods.

My name is Ann [436]

Answer: Myocardial infraction can be defined as the condition which is caused due to absence of oxygen in major parts of the heart.

This also causes ischemia which occurs primarily and myocardial infraction occurs secondarily to this.

When, oxygen and nutrients from the blood reaches to the area which was deprived of oxygen results in inflammation and oxidative damage.

This is caused due to induction of oxidative stress rather than the normal functioning of the body.

Which of the following activities are examples of data organization and analysis?. . check all that apply. . . A. Drawing a pie
Nimfa-mama [501]
Data organization refers to the method of classifying and organizing sets of data to make them more useful. Analysis is a detailed examination of something. It is what you do with the data you collected. Based on this, we can say that B, counting the number of fish for each species, and D, transferring the data from the fish counter to a computer program would both be examples of data organization and analysis.

jeka57 [31]
In order for natural selection to take place we must have "variety in a population". This variety of traits is what allows natural selection to "pick" the most favorable traits.

The inner mitochondrial membrane contains numerous inward folds called cristae, which greatly increase the surface area of this
erastova [34]

Answer:the villi of the intestine

Explanation:like the cristae of the mitochondria which increase the surface area for the production of ATP,the villi of the intestine acts similarly.

In animals, digested food pass from the stomach to the intestine. In the intestine , enzymes acts on the food. Absorption of food takes place there and there are some structures that facilitates it. The walls of the intestine have numerous foldings , alongside the presence of finger like projection called villi. Microvilli are also presence from the cell walls of the intestine . These projections increase the surface area for the absorbing of food .they brush against food in the intestine and promotes absorption of nutrients.

Name the three types of population distribution, describe each, and explain the conditions that govern each.
mel-nik [20]

Answer:

Three types of population distribution:

Clumped.

Random.

Uniform.

Explanation:

1. Clumped:

This is the most common pattern of population dispersion.

organisms are clustered together in a group.

This may reflect the patchy distribution of resources in the environment.

2. Random:

This is a typical distribution where individuals do not interact strongly.

The organism has unpredictable distribution.

3. Uniform:

This is the typical environment where individuals compete with each other for scarce resources like water in the desert.

organisms are evenly spaced over the area they occupied.
