Answer:
The correct answer is - Anaphase.
Explanation:
Cell division can be either mitosis or meiosis. Mitosis cell division has these phases:
A. Interphase - non-dividing phase with to G1, S and G2 sub phase. In this genetic material doubles and cell size increases.
B. Prophase- chromosomes shorten and condense by coiling. Centrioles move in opposite directions.
C. Metaphase - spindle fibres bind to kinetochores and pulls it the chromosomes on the equator of the spindle forms a plate called the metaphase plate.
D. Anaphase- these get condense and centromeres split into two and the spindle fibres pull the daughter centromeres to opposite poles.
E. Telophase is the last phase of Mitosis.
Answer:
As a cell grows bigger, its internal volume enlarges and the cell membrane expands. Unfortunately, the volume increases more rapidly than does the surface area, and so the relative amount of surface area available to pass materials to a unit volume of the cell steadily decreases.
Answer:
like DNA, RNA is made up of nucleotides.There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Answer:
Traits are inherited when genes are passed from parents to offspring.
Explanation:
that is the definition of family traits

Overfishing occurs when more fish are removed from an ecosystem than can be maintained by the population,
Overfishing can lead to significant population declines in economically important species. The passage describes

According to the passage, which mechanism explains the observed changes in fish size over time?
A. Smaller fish produce fewer eggs than larger fish do, so they contribute fewer offspring to the next
generation.
B. Fish that are small enough to escape fishing nets are more likely to survive than larger fish.
C. Scientists found that Atlantic silversides exhibited changes in feeding and foraging rates after four
generations of selection,
D. The average size of pink salmon returning to spawn decreased from 6.0 pounds to approximately 4.5
pounds.
