How is the small intestine designed to absorb digested food ?​

Answers

Answer:

Small intestine is designed to more and more area for absorption of digested food and transfer into the blood for circulation throughout the body. The inner lining of small intestine has a large number of finger-like projections called villi. These villi provide a large surface area for absorption of food.

Explanation:

Hope this helps!

Have a good day or night!

➜ The small intestine is the main region for the absorption of digested food. The inner lining of small intestine has millions of tiny finger-like projections called villi. The presence of villi gives the inner walls of the small intestine a very large surface area for absorption of digested food. The villi are richly supplied with blood vessels which take the absorbed food to each and every cell of the body.

Compare and contrast gradualism and punctuated equilibrium. Provide at least one comparison and one difference in your answer. You may use examples for each if that helps you with answering the question.

Answers

Answer:

Gradualism and punctuated equilibrium both are the process of evolution of species over time. However, the gradualism process involves the evolution that occurred slowly, occurring in small periodic changes in the gene pool over a long period of time. Whereas Punctuated equilibrium takes place there are longer periods of apparent stasis interrupted by the sudden change.

They both help in finding the relative change in evolution rate and assist in the study of the anatomical changes occurred during the evolution in different kind of animals or organisms.

How might green spaces help reduce the negative impact that humans have on Earth’s water supply?

Answers

It would give nature a place to fight back, and become more healthy, and less hindered. Cities mess up the evaporation cycle, and because of parks, the water is able to be soaked up by grass, and then released through evaporation. When it rains over a city, the water goes into gutters, and becomes more polluted.

The data are shown in the chart below. 4. State one reason why an individual's pulse rate increased during exercise 5. Calculate the average pulse rate before exercise for this group, to the nearest tenth___________bpm . 6. State why the individuals in this group have different pulse rates before exercise *

Answers

Answer:

4. (answered below); 5. 66.2; 6. (answered below)

Explanation:

4. The individual's heart rate increased because the individual needs more oxygen supplied to their muscles so the heart has to pump the oxygenated blood through the body at a faster rate.

5. Take average of the number of the pulse before exercise:

(68 + 70 + 54 + 64 + 75) / 5 = 66.2

6. Different individuals are different sizes and are in different states of health. An individual who is more physically fit will have a slower rate rate because their heart muscle is "exercised" or worked more and pumps blood more efficiently.

Answers

Answer:

Colonization by plants may provide habitat, facilitating colonization of animal species.

Early colonizing plants may increase the nutrient level of the soil, facilitating the colonization of other plant species.

Animal colonizers may increase pollination of some plant species, facilitating their colonization.

Explanation:

The plants provides habitat as well as food to organisms that helps in the colonization of that organisms because every organism needs food and living place for its survival. Some plants increase the nutrient level in the soil through fixation of nitrogen which leads to the colonization of other plant species in that environment. Some animals causes pollination of plants which helps them in their colonization so all these organisms have a positive impact on the occurrence of other species.

Design an experiment that would help you collect the data you have identified in question four independent variable - x , dependent variable - y.

What is independent variable?

The indepent variable is something that is stable , it does not change & the dependent variable is that variable that depends on the independent variable.

The experimenter's chosen variable or variables are considered independent. The anticipated "cause" will be this manipulation. The independent variable's value determines how much the dependent variable is worth.

The result of the cause will be this (if the manipulation succeeds). One group of volunteers receives a medication, while the other receives a placebo. Cancers diminish in the medication group but they do not in the control (placebo) group.

Increasing the alveolar ventilation rate will Group of answer choices increase the partial pressure of oxygen in the alveoli. decrease the rate of oxygen diffusion from the alveoli to the blood. increase the partial pressure of carbon dioxide in the alveoli. decrease the rate of carbon dioxide diffusion from the blood to the alveoli. have no effect on either the partial pressure or diffusion rate of gases.

Answers

Answer:

Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.

Explanation:

Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.

A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli.  This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.

Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)

If the  alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.

If the  alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.

a. Many eukaryotes have no DNA
b. Many eukaryotes have many cells
c. Many eukaryotes have no cell membrane
d. Many eukaryotes have DNA in cytoplasm

Answers

Answer:

c

Explanation:

The statement that represents a characteristic of many eukaryotes is that many eukaryotes have many cells. Thus, the correct option for this question is B.

What do you mean by Eukaryotes?

Eukaryotes may be defined as the type of living organisms that significantly have a well-defined nucleus along with other membrane-bound cell organelles. These organisms have a complex level of compartmentalization.

According to the context of this question, almost all eukaryotes have DNA in their nucleus. This is because it is considered its genetic material. So, options A and D are eliminated.

The cell membrane is the characteristic feature of every eukaryote because this membrane separates the inner environment of the cell from external conditions. So, option C is eliminated as well.

Therefore, the statement that represents a characteristic of many eukaryotes is that many eukaryotes have many cells. Thus, the correct option for this question is B.

According to the National Highway Safety Administration, the rate of crashes, both fatal and nonfatal, for sixteen-year-old drivers is almost ten times the rate as that of drivers aged thirty to fifty-nine, as calculated per mile driven. No one disputes the idea that raising the legal driving age will create issues and difficulties for many; however, these issues pale in comparison with the issue of safety.
