An example of mitosis at work is a leaf turning yellow.
growing.
taking in carbon dioxide.
performing photosynthesis.

The right answer is Growing.

Mitosis is the cell division that allows an equal distribution of genetic information from an initial mother cell to two daughter cells while retaining the karyotype over the cell generations.

Mitosis will ensure - sometimes unfortunately - the good fulfillment of several phenomena:

1. embryonic development,

2. the general growth of organisms from birth to adult size,

3. the continued growth of certain organisms and / or organs; for example, trees, hair, teeth in ruminants, nails, ...

4. to renew dead cells; for example skin cells, red blood cells, ...

5. to ensure healing,

6. to preserve cellular identity during the development and renewal of cells belonging to the same organs, tissues, ...

7. As a result of disorders: cancers

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.

the correct answer is option d.
