Answers
Answer:
New cells produced within uterus (or any other organ) as a direct result of mitotic cell division.
Mitosis is the type of cell division which results in the formation of two daughter cells with same number of chromosomes as that of parent cell. It plays an important role in growth and repair of cells and tissues in multi-cellular organisms such as human beings.
For example, mitotic division helps in formation and repair of uterus lining lost during menstrual phase. Similarly, it keeps replacing the dead skin cells lost from our body surface on regular basis.
Meiotic division on other hand is used only in the formation of haploid gametes i.e. sperm in males and egg in females.

25 x $ 135 = $ 3375
Next, we just need to divide this amount to total contributors
$ 3375 / 45 = $ 75 per person
Hope this helps
Answer:
Each person needs to contribute is $75.
Step by step explanation:
It is given that the number of people is 25. Each of them would need to contribute $135.
Total amount contributed by 25 people is the product of 25 and 135.
Total amount contributed by 25 people is $3375.
Now 45 people has to contribute the same amount $3375.
If 45 people donate $3375, then each people donate
Therefore, each person needs to contribute is $75.

the answer is D. it shows how the population changed because the shorter legged animals survived and continued the population while the long legged animals died away.
Final answer:
Natural selection occurs when there is variation within a species, inheritance of the variations, and a limit on resources. This leads to individuals with advantageous traits having a higher chance of survival and reproduction. The best example given was a population of mammals that evolved to have shorter legs due to a change in their habitat.
Explanation:
Natural selection is a crucial mechanism of evolution and it occurs when three conditions are present: variation within a species, inheritance of those variations, and a population limitation on resources consumed. This leads to a survival competition, where advantageous traits increase an individual's chances of survival and reproduction, thus passing these traits onto the offspring.
In the given options, the description that fits most closely with natural selection is: 'D. A population of mammals varies in the length of their legs, water levels rise and the habitat becomes swampy, the individuals with shorter legs are better able to swim to food, the population evolves to become shorter-legged'. This example demonstrates genetic variation (the different leg lengths), selection pressure (the change in habitat), and selection advantage (shorter legs being more suitable for the new conditions).

Final answer:
The function of the respiratory passageways in humans is to permit the exchange of gases, mainly oxygen and carbon dioxide, between the body and the external environment through the process of respiration.
Explanation:
The main function of the human respiratory passageways is primarily to permit the exchange of gaseous substances, namely oxygen and carbon dioxide, between the body and the external atmosphere. This is achieved through a process called respiration.
When we breathe in, oxygen from the air gets filtered and warmed in the respiratory passageways and reaches our lungs. It then gets transferred to the bloodstream. On the other hand, the carbon dioxide, a gaseous waste product of our body cells, moves from the bloodstream to the lungs, gets expelled through the respiratory passageways when we breathe out.
It's worth mentioning that the other options such as allowing digestive end-products to touch body cells or regulating the amount of ammonia and salt in body fluids are not direct functions of the respiratory passageways.
