During his voyage on the HMS Beagle, Darwin observed the
beaks and behavior of finches. These finches were similar
in some ways to the single finch species that existed on
the mainland of South America. On the Galápagos Islands,
however, there were 13 different species, each with
different beaks and different diets. Later, Darwin
hypothesized that natural selection could explain the
differences in the finch species. Many years later,
Rosemary and Peter Grant of Princeton University began to
test Darwin's hypothesis.
Scientists have recently developed a hypothesis based on
evolutionary concepts and the Grants' work. First, finches
from South America arrived on one of the islands. Then,
the finches that arrived on the island had to survive in a
new environment. The plants on the island were different
from the plants on the mainland. As a result, the
population on the island evolved differently from the
population on the mainland.
Later, a few finches from the island may have flown to
another island and begun the speciation process again.
This process may have been repeated many times. Now
there are 13 distinct species.

Darwin's ideas about competition, which of the following changes is MOST likely to occur, Both populations will increase and decrease in a cycle.

Amensalism is an relations where an organism inflicts damage to another organism without any expenses or benefits received by itself.

Amensalism explains the adverse effect that one organism has on another organism.

Most of the baryonic matter (ordinary matter) of the universe is interstellar gases and stars. Baryonic matter is the visible matter. Thus, the correct answer is D.

Visible matter is also known as the baryonic matter. It consists of baryons which are subatomic particles such as protons, neutrons and electrons.

In cosmology, baryonic dark matter is the dark matter composed of baryons. Only a small proportion of the dark matter in the universe is likely to be baryonic the rest of the matter is all dark matter. Baryonic matter only includes matter composed of baryons.  It can be described as the baryons are made up of protons, neutrons and all the objects composed of them (i.e. atomic nuclei), but exclude other things like electrons and neutrinos.

Therefore, the correct answer is D.

Explanation:

Meiosis and fertilization, two processes are responsible for the passage of hereditary information from generation to generation in mammals, birds, reptiles, fish and other animals.

Meiosis occurs in chromosomes which allows the production of haploid germ cells necessary for seˣual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.

Fertilization restores the diploid number of chromosomes, that is 46 in human being. It provides stimulus for the ovum to complete its maturation.

Answer: Delta

Explanation:

A delta is the sediment deposited by the surface water. When the river flows it carries the sediments from the bedrock and also from the surface of the top layer of the soil. These sediments are deposited on a fan like formation that is called as delta. It leads to the development of a landform. It is the most fertile landform as the sediments are rich in mineral content that promote the growth of the plants. This develops when river enters into the ocean, estuary, reservoir, lakes, and any other water body supplying the sediments on the surface.

Answer:

Women who carry one copy of the mutated gene still have normal color vision because they have another copy, which is not mutated, in the other X chromosome that will be the dominant one. As a result, the women are carriers of the mutated gene but not color blind.

Explanation:

Colorblindness is a sex-linked mutation. A woman has two X chromosomes, while a man has one X chromosome and one Y chromosome. The mutated gene that causes color blindness is on the X chromosome, and it is OPN1LW. So if a woman has one mutated OPN1LW in one of her two X chromosomes, the OPN1LW gene in the other X chromosome will be the dominant one stopping the woman from being colorblind.

In the case of men, as they only have one X chromosome, if there is a mutation on the OPN1LW in the X chromosome, the men will be colorblind because there is no extra copy of the gene, as it is in women.

Answer:

Core body temperature The body can only stay at a constant temperature if the heat generated is balanced and equal to the heat lost. Although the core temperature must be close to 37°C, fingers and toes can be colder. This is because energy is transferred from the blood as it travels to the fingers and toes.

Answer: When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.

Answer:20 to 1

Explanation:

]

The ratio of the size of the bacterial cell to the size of the mesophyll cell is 1:20. It means that 20 bacterial cells can fits into a mesophyll cell.

Given here,

Size of the bacterial cell  = 1 micrometer

Size of the mesophyll cel=  0.05mm​

Equalize the measuring unit,

1 micrometer   = [tex]\bold{10^-^6 m}[/tex]

1 millimetre = [tex]\bold { 10^-^3 m}[/tex]

So the ratio will be

[tex]\bold { = \dfrac{ 1 x10^-^6 m}{0.05 x 10^-^3 m} }\\\\\bold { = \dfrac 1{20} }[/tex]

Therefore,  the ratio of the size of the bacterial cell to the size of the mesophyll cell is 1:20.
