Answer: Genetics and Pressures
Explanation:
For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.
Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.
Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.

Carbon dioxide is called a greenhouse gas because it helps to trap heat from the Sun in Earth’s atmosphere. This keeps Earth’s temperature warmer than it would otherwise be. In this respect, how does carbon dioxide in the carbon cycle affect water in the water cycle?
A. It allows the oceans to contain more water than they would otherwise be able to. B. It leads to ocean water dissolving more salt than it has dissolved in the past. C. It enables more water to evaporate and enter the atmosphere. D. It causes more water to be frozen in ice caps at the poles
Carbon dioxide in the carbon cycle affect water in the water cycle in a way that it enables more water to evaporate and enter the atmosphere. (Option C)
How Carbon Dioxide Affects Water CycleCarbon dioxide molecules provide the greenhouse heating needed to maintain water vapor concentrations. When carbon dioxide concentrations drop, Earth cools, some water vapor falls out of the atmosphere, and the greenhouse warming caused by water vapor drops. Dissolving carbon dioxide in the ocean creates carbonic acid, which increases the acidity of the water.

How is inertia taking place if a penny is at rest?
A penny is at rest is experiencing inertia because it is not moving.
What is inertia?According to Newton's first law of motion, every object at rest or uniform motion in a straight line will continue in that state unless it is acted upon by an external force. This law is also called law of inertia.
Inertia depends on mass because the more massive an object is, the more reluctant it will be to move.
Thus, a penny is at rest is experiencing inertia because it is not moving.

How do cytotoxic t-lymphocytes destroy infected cells?
Cytotoxic T cells kill their targets by programming them to undergo apoptosis. When cytotoxic T cells are mixed with target cells and rapidly brought into contact by centrifugation, they can program antigen-specific target cells to die within 5 minutes, although death may take hours to become fully evident.
How do T lymphocytes destroy infected cells?In cellular immunity, a killer T cell identifies and kills a virus-infected cell because of the viral antigen on its surface, thus aborting the infection because a virus will not grow within a dead cell.
Thus, Cytotoxic T cells kill their targets by programming them to undergo apoptosis.
