Answer:
Genetic linkage is a phenomenon where two genes exist close to each other on the same chromosome. ... In addition, when a single trait is determined by multiple genes and the effect of each of these genes is graded, Punnett squares cannot accurately predict the distribution of phenotypes in the offspring.

Suppose for some reason DNA production suddenly stopped occurring. Explain the consequences that would occur and why homeostasis would not be maintained.
Answer:
a
Explanation:
Answer:
For homeostasis to occur, DNA production is super important. Taking in consideratoin that DNA production suddenly stopped occuring, Homeostasis wouldn't be able to occur because the Nucleus wouldn't be able to produce RNA which is released into the cell cytoplasm.

what are toes inside of the human body and what do they produce?
Answer:
Each toe consists of three separate bones and two joints, except for the big toe, which has only two bones — distal and proximal phalanges — and one joint, like the thumb in the hand. The phalanges are made up of the distal phalanges at the tip, middle phalanges, and proximal phalanges, closest to the metatarsals.

what happens when an atom has lost an electron comes in contact with an atom that has gained an electron?
Answer: When an atom that has lost an electron comes in contact with an atom that has gained an electron, usually the the two atoms would attract each other and form a compound. This compound would be ionic since it is governed by ionic bonding.

What important process happens at the capillaries?
Answer: Capillaries connect the arterial system — which includes the blood vessels that carry blood away from your heart — to your venous system. Your venous system includes the blood vessels that carry blood back to your heart. The exchange of oxygen, nutrients, and waste between your blood and tissues also happens in your capillaries.

if the pressure of a sample of gas is doubles at constant temperature, what happens to the volume of the gas?
Answer:
If the pressure doubles, the volume decreases in half.
Explanation:
The relationship between the pressure and the volume of a gas can be explained by Boyle's Law. According to this law, the volume and pressure of the gas has an inversely proprietary relationship. In that case, if the pressure on the volume decreases in the same intensity and if the pressure decreases, the volume increases in the same proportion. In that case, if the pressure of a gas sample doubles, the volume decreases by half.
The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, ________.
Answer: The oxygen content of the water decreases
Explanation:
The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, the oxygen content of the water decreases.
The temperature and the salt content of a body of water determines how much oxygen it can hold.
The oxygen content of warm water decreases because the temperature of the water causes the water molecules to move faster. This leads to the expulsion of oxygen from the water, making it contain less oxygen.
Also, salty water will lead to a decrease in oxygen because of the presence of sodium chloride ions.
Therefore, a warmer and saltier water will contain a less amount of oxygen.

What are the main features of the Fungi kingdom?Fungi are heterotrophic and eukaryotic organisms that can be unicellular or multicellular. The vast majority of species are filamentous, and these filaments are called hyphae. Some fungi are formed by several densely packed hyphae, which form the so-called mycelium.
The Fungi Kingdom is represented by unicellular or multicellular eukaryotic organisms, being found in the most diverse types of environments. Fungi include mushrooms, molds, wood ears, lichens, among other organisms.

Answer:
DNA is arranged on chromosomes in segments called genes. One gene tells the cell how to make one protein. Different variations of a gene are called alleles. Each parent passes one allele to the child for each gene.

Question 4: Suppose there were changes in the habitat that caused this actual value. What might a
combination of those changes be?
Please help if you’ve done this for biology on e2020
Answer:
The amount of precipitation reduces by 20% over time. It will have an impact on the habitat because species that have adapted to drier climates will supplant those that are less suited to the new climate.
Explanation:
A combination of conditions (factors) that caused these changes in the habitat are:
Hot summersHarsh wintersCold springs What is a habitat?A habitat refers to a combination of resources and geographical area that defines where the particular species of a living organism such as a rabbit, generally lives and thrives.
In this scenario, a combination of conditions (factors) that caused these changes in the habitat are:
Hot summersHarsh wintersCold springsIn conclusion, these conditions (factors) would kill or make the population of rabbits in this habitat not to reproduce, which may cause them to emigrate.
