If a disease strikes the snake population in the food chain shown, what will be the initial effect on the populations of hawks and rabbits? a. the populations of hawks and rabbits will decrease. b. the populations of hawks and rabbits will increase. c. the population of hawks will increase. the population of rabbits will decrease. d. the population of hawks will decrease. the population of rabbits will increase.

The answer is D. The hawks will decrease because there is a limited amount of food for them to eat.

Option D

Explanation:

In case of a food chain, snakes eat rabbit and hawk eats snake.If a disease strikes the population of snakes then it is obvious that its population will decrease.

If the population of snakes will decrease then the population of rabbits will increase as there will be no more snakes to eat rabbits.

Along with this the population of hawks will decrease as there will be no food( snakes) for them to eat.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.
