B) founder effect
C) bottleneck
D) stabilizing effect
Population decline causes an extreme genetic drift called a bottleneck effect. The correct option is C.
What is bottleneck effect?The bottleneck effect describes how a population's size is reduced and then increased, affecting the distribution of genetic variation among its members.
It happened when the population reduced severely. Events like natural disaster or decline of the population.

Certain traits helped organisms survive and reproduce
Better than other organisms without those traits.
5. Organisms can never become extinct.

Explanation:
in 1, we need time therefore both. In 2, Lamarck because in Darwinian evolution, species change not organisms. In 3, Darwin because of natural selection, mutation, and probably a little bit of heredity. 4 is Darwin because in Lamarckian evolution. 5 is Lamarck because based on natural selection, organisms should go extinct. 6 is both because they both rely on the environment. 7 is both because of heredity. 8 is Darwin because in Lamarckian evolution, traits acquired throughout ones lifetime can be passed down to offspring. 9 is Lamarck because in Darwinian evolution, organisms do not decide their traits. 10 is both because both idea ssupport the idea that organisms, be it in Lamarckian or Darwinian evolution, are still and will carry out on changing.

5. A mother's diet is very important throughout her pregnancy but especially during the first
trimester. Vitamins and minerals provide essential nutrients during this stage of
development. Vitamins A, D, and Beta Carotene help bones and teeth grow and harden,
Vitamin E is used in the formation of red blood cells and muscles, and Vitamin C helps build
a healthy immune system. Which of the following would most likely result from a poor diet
during the first trimester?
A. Less production of urine
B. Response to outside stimulus
C. A functioning nervous system
D. Abnormal development of the heart and lungs
Poor nutrition during the first trimester of pregnancy can have negative effects on both the mother and the unborn child. A poor diet is more likely to cause improper heart and lung development.
What is the dependence of the bones ?The growth of bones and teeth depends on vitamins A, D, and beta-carotene, whereas the development of red blood cells and muscles depends on vitamin E. A robust immune system may be built using vitamin C.
Without these nutrients, the baby's heart and lungs could not develop normally, which might result in life-threatening medical issues. Because the body is unable to absorb the essential nutrients from meals, poor nutrition can also result in reduced urine output.
Dehydration from this may result, which may further contribute to healthcare issues. Additionally, because the baby's nervous system could not be fully formed, a poor diet during the first trimester can result in a diminished reaction to external input.
Problems with motor and cognitive development may result from this. To sum up, a bad diet throughout the first trimester might result in major medical issues for both the mother and her unborn child. A poor diet is more likely to cause improper heart and lung development.
In addition, a poor diet might cause issues with motor and cognitive development, reduced sensitivity to external stimuli, and decreased urine output. It is therefore essential that pregnant women eat a balanced diet with the necessary vitamins and minerals to ensure the health of both mother and baby.
