What contributed to the specification in Darwin's Finch theory
Keith_Richards [23]

Answer:

On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.

Darwin's finches are a classical example of an adaptive radiation. Their common ancestor arrived on the Galapagos about two million years ago. During the time that has passed the Darwin's finches have evolved into 15 recognized species differing in body size, beak shape, song and feeding behaviour.

Natasha2012 [34]

loblolly pine trees

Explanation:

Population density refers to the amount of organisms living in a particular area:

            Population density = \frac{number of organisms}{Area}

Area of the forest = 10acres

Population densities of:

  White-tailed deer = \frac{8 white tailed deer}{10acres}

                                 = 0.8white tailed deer/acres

   Coyotes = \frac{7 coyotes}{10acres}= 0.7coyotes/acres

   Armadillos = \frac{45 armadillos}{10acres} = 4.5armadillos/acres

   loblolly pine = \frac{231loblolly pine trees}{10acres} = 23.1loblolly pine trees/acre

The population with the highest density is that of the loblolly pine trees with 23.1 of the trees in an acre.

What is the purpose of MITOSIS?
Mumz [18]

Answer:

D

Explanation:

A: to create sex cells of reproduction.

This is the purpose of meiosis: a cell division process. It creates gametes, or sperm and eggs.

B. to provide the cells with food

This would be eating for animals, or photosynthesis for plants. When animals eat, it provides their cells with food. When plants photosynthesize, they create their own food in the form of glucose.

C. To give the cell energy

This would be cellular respiration. It turns food and glucose into usable energy called ATP.

D.

This is the correct choice. Mitosis is cell division, which means it creates new cells. This allows organisms to grow and repair.
