Answer:

The correct answer is option A, that is, ecological competition.

Explanation:

The small number of finches reached the Galapagos Island and established themselves. The phenomenon of the geographical isolation of the Galapagos Islands resulted in the inhibition of interbreeding between the populations of finches found on the different islands.  

The distinct populations of finches gathered changes to get amended to accessible food. The gathering of genetic variations and geographical isolation resulted in the reproductive isolation between them. In order to get better amended with the surroundings, the population of finches encountered with enhanced genetic variations between them, which is considered as ecological competition. The repetition of the entire procedure of the chain of islands resulted in the evolution of distinct species of finches.

Answer:

c. The pharynx

Explanation:

The pharynx is a tubular organ that begins in the funnel-shaped neck down the neck, extending from 12 to 15 cm in length and about 35 mm at its onset and about 15 mm at the end. its ending. It has communication with the esophagus, nasal passages and the ears. The pharynx is located behind the nasal passages and in front of the cervical vertebrae, remains attached to the larynx and esophagus.

The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there a
Agata [3.3K]

Answer:

2,855 is the size of the colony of mosquitoes after 4 ​days.

Explanation:

The law of uninhibited growth is given as:

A=A_o\times e^{k\times t}

A_o= Original amount

A = Amount after time t

k = Positive constant repressing the rate of growth

We are given with:

Original population of mosquitoes = 1000

Population of mosquitoes after 1 day =1300

t = 1 day

1300=1000\times e^{k\times 1 day}

k = 0.2623 day^{-1}

Population size of mosquitoes after 4 days

A_o=1000, k= 0.2623 day^{-1}

A =? , t = 4 days

A=1000\times e^{ 0.2623 day^{-1}\times 4 days}

A =2,855.36 ≈ 2,855 mosquitoes

2,855 is the size of the colony of mosquitoes after 4 ​days.
