Answer:
While the number of genes in an organism's DNA (red bars) varies from species to species (numbers at right), it is not always proportional to genome size (blue bars, in millions of base pairs). Note how many genes a fruit fly can squeeze out of its relatively small genome.
What is a gene?
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.Comparative genomics also provides a powerful tool for studying evolutionary changes among organisms, helping to identify genes that are conserved or common among species, as well as genes that give each organism its unique characteristics.While the number of genes in an organism's DNA varies from species to species, it is not always proportional to genome size.Learn more:

What is an example of a relationship between organisms in which an organism produces energy that is used by another organism to The detriment of the original organism
Answer:
Tree frogs use plants as protection. Golden jackals, once they have been expelled from a pack, will trail a tiger to feed on the remains of its kills. Goby fish live on other sea animals, changing color to blend in with the host, thus gaining protection from predators.

What is the sediment deposited by surface water?
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.

What are bio-fuels considered carbon neutral?
Answer:
Science considers biodiesel to be carbon-neutral because the plants that are the sources of the feedstocks for making biodiesel, such as soybeans and palm oil trees, absorb carbon dioxide (CO2) as they grow. The absorption of CO2 by these plants offsets the CO2 that forms while making and burning biodiesel.

Opsins are proteins that are found in the light-sensing cells in the human eye. Different opsin proteins are sensitive to different colors of light. The instructions for creating the type of opsin sensitive to red light are found on a gene known as OPN1LW, which is on the X chromosome. A genetic mutation in the OPN1LW gene can lead to a form of color blindness that affects a person's ability to detect red light. However, women have two copies of the X chromosome, and they have normal color vision if only one copy contains the mutation. Why do women who carry one copy of the mutated gene still have normal color vision?
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.

Calculate the ratio of the size of the bacterial cell to the size of the mesophyll cell
bacterial cell is 1 micrometer
mesophyll cell is 0.05mm
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.

Which is not part of the function of the normal cell cycle? (A) cell growth (B) DNA replication (C) cell division (D) cell death
Cell death is not part of the function of the normal cell cycle, a strictly controlled cell mechanism known as programmed cell death, or apoptosis, hence option d is correct.
What is cell death?Eliminates cells that are no longer required or pose a hazard to the organism in multicellular creatures.
The body's mechanism of cell death is crucial. When cells are not required, as at some developmental phases, for example, they are removed.
For instance, the outer layer of the skin is formed of dead cells, which form a structure in the body that is also apoptosis.
Therefore, cell growth, DNA replication, cell division are part of the cell cycle, a controlled cell death mechanism known as programmed cell death, or apoptosis, hence option D is correct

How is your body temperature held constant despite different weather temperatures
outside?
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.
