Only about _____ of genes are different from one person to the next. Those that are different are called _____.
The correct answer is A; 1%, alleles, A gene mutation is a change that occurs in one or more genes (myoo-TAY-shun). Certain genetic mutations can cause genetic disorders or illnesses.
The human genome is substantially same in all individuals. There are, however, variations across the genome. This genetic variety accounts for around 0.001% of each individual's DNA and results in differences in appearance and health. People who are closely related share more DNA.
There are genes that are dominant and recessive. The most common interaction between alleles is a dominant/recessive relationship. When one allele of a gene effectively overrules the other (recessive) allele, the dominant allele is said to exist. Correlations between dominant and recessive genes can be seen in eye color and blood type.

What are two similarities between natural and artificial selection?
Natural selection is a process that occurs when environmental factors that limit survival and reproduction, such as harsh environments or mating competition, are present.
Selected breeding falls within the definition of "artificial selection." Breeding is the natural act of two species mating, but selective breeding is an artificial process where people intervene and pick certain organisms to marry. Selective breeding and natural selection can be contrasted in three ways.
Artificial selection is a human-driven process. Natural selection is governed by environmental demand for selection. The artificial selection process is managed by breeders. Natural selection has significantly boosted biological diversity on Earth. As opposed to natural selection, artificial selection makes it simpler for the breeder to pass on desired qualities.

What term is used to describe an organism that has two identical alleles for a trait both alleles either upper case or lower case )?
Diploid organisms is used to describe an organism that has two identical alleles for a trait both alleles either upper case or lower case .
Each chromosome in diploid cells has two identical copies, typically one from the mother and one from the father. Mammals are nearly all diploid organisms. The only known exceptions are the presumed tetraploid (having four chromosomal sets) plains viscacha rat and golden viscacha rat (as of 2004).
The huge genome sizes of these two rodents are best explained by the amplification and dispersion of repetitive sequences, according to some genetic studies, which reject any possibility of polyploidy in mammals as implausible. A small percentage of the cells in all healthy diploid individuals show polyploidy. 46 chromosomes can be found in human diploid cells.

Occasionally cells stop dividing and enter another phase, G 0 . If you damage your liver, new liver cells can be produced to replace up to 75% of the liver. However, if you sustain brain dam-age, your body does not produce new brain cells. Explain this observation using what you have learned about the cell cycle.
Cell division is essential for growth and development of organisms. Cell division is regulated by the cell cycle, which consists of four phases: G1, S, G2, and M.
During G1, the cell grows and performs its normal activities. The S-phase is when the cell makes DNA. The cell gets ready to divide during G2. The cell divides into two daughter cells during the M-phase.
Occasionally, cells enter a resting phase called G0. This phase is characterized by the cell not actively growing and dividing. Cells in this phase are usually post-mitotic, meaning they are not planning to divide anymore and have exited the cell cycle.
Liver cells can divide and enter the cell cycle and produce new cells if the liver is damaged, up to 75%. This is possible because liver cells are bi-potent, meaning they have the potential to divide and create new liver cells. On the other hand, brain cells are post-mitotic and cannot enter the cell cycle and divide. Therefore, if the brain is damaged, it cannot produce new brain cells since they are not able to divide.

What are two factors that increase the genetic variation in a population ?
Gene flow and genetic drift are two factors that increase the genetic variation in a population.
Genetic variations are the changes or alterations which can occur in the sequence of gene of the DNA. These genetic variations are very necessary as they enable different living beings to evolve and also survive. There are two factors which can cause an increase in the genetic variation of a particular population and they are gene flow and genetic drift.
Gene flow can be defined as the movement of genes which occurs in and out of a specific population. The in-flow of genes in a population can help increase the genetic variation of the individuals that are a part of that population. Genetic drift is defined as the change in allelic frequency of a population which occurs by chance. It brings about genetic variation.

O
D. Warm air moves upward in the center, cool air moves downward at
the edge
In a global convection cell the correct option is (C). Cool air and warm air repeatedly collide, pushing air up and causing storms.
In a convection cell, the alterations are profound. The air molecules start to move and vibrate as the air at the cell's base heats. As a result, they start to spread out and collide, which reduces the density of the air parcel.
Convection is a pattern that occurs on a large scale. On a smaller scale, it also takes place within certain storms. However, because to Earth's rotation, the air that travels north and south from the equator likewise revolves with the Earth. Northbound air makes a right turn. Southbound air turns to the left.
Less dense air rises and moves away from the equator in a global convection cell. And the dense air from the pole flows backwards toward the equator as it descends. The poles can be thought of as the longitudinal edges of the earth's sphere, with the equator acting as its centee. The Coriolis Effect, a result of the spinning of the Earth, also aids in this airflow.

3. Which type of molecule is more likely to quickly pass through a cellular membrane via simple diffusion, polar or non-polar
Non-polar molecules are less likely to be drawn to the polar phospholipid heads of the cell membrane, which makes them more likely to move across a cellular membrane swiftly via simple diffusion.
This indicates that they can more readily traverse the hydrophobic (non-polar) tail section of the cell membrane. Polar molecules, on the other hand, are drawn to the phospholipid heads and may have trouble crossing the cell membrane.
Simple diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration without the aid of a transport protein. The cell membrane is a selectively permeable membrane, which means that it only allows certain molecules to pass through.
Non-polar molecules, such as hydrocarbons, can easily diffuse through the hydrophobic (non-polar) tails of the phospholipid bilayer because they are not attracted to the polar heads of the phospholipids.

Why was Lucy's mutation not a problem?
Because it has no effect on the active site, the gene mutation is not an issue.
Lucy was able to produce more proteins and break down deoxyadenosine correctly after receiving stem cell therapy, which helped her fight off the additional stop protein.
The active site will not be affected by the gene mutation. This is because the non-essential amino acid or protein in the molecule is affected by the mutation. The molecule maintains its original shape and state as a result. In addition, the active site of the quaternary protein structure comprises a large number of proteins. Therefore, the mutation won't have a significant impact on the molecule's overall structure or ability to perform its function.
