Answer:
Homozygous Dominant
Explanation:
Two atoms of element a unite to form a molecule with the formula a2. The bond between the atoms in the molecule is.
Two atoms of element A unite to form a molecule with the formula A₂. The bond between the atoms in the molecule is nonpolar covalent.
Only nonmetаls cаn combine to form molecules of the type А₂ (e.g. F₂, Cl₂, Br₂, I₂, H₂, O₂, N₂). When nonmetаls combine with nonmetаls, they shаre pаirs of electrons to fulfil the octet's rule. The bond in which elements shаre electrons is known аs covаlent.
The polаrity of the covаlent bond depends on the difference in the electronegаtivities of аtoms thаt form it. Since А₂ is formed by 2 аtoms of А (sаme electronegаtivity), the difference in their electronegаtivities is zero аnd the bond is clаssified аs nonpolаr.

Genes are segments of dna that determine the phenotype of an individual. Pea colors can be yellow or green. When two plants that produce yellow peas were crossed, the offspring produced green peas. This is because the parents were.
When two plants that produce yellow peas are crossed, the offspring produce green peas. This is because the parents are heterozygotes.
Crossed yellow pea plants produced green pea offspring. This means that the yellow color is the dominant trait, and the parent plant has a heterozygous (Yy) genotype.
Dominant genes always cover recessive genes. That is, if you have one 'Y' gene, your beans will be yellow, even if you have a 'y' gene for green beans the phenotype will be yellow.
There are two distinct genotypes of peas, "YY" (homozygous dominant) and "Yy" (heterozygous dominant). And, all peas will have the same genotype, "yy" (homozygous recessive).
If you have two different alleles for a gene, you can get two different results from that gene - like a yellow pea turning into a green bean.
So that the offspring produce green peas. This is because the parents are heterozygous.

Proximal, distal, and oblique are the correct words for the various ways an organ can be divided.
What is proximal?
Proximal means closer to the center (trunk of the body) or point of attachment to the body. If another reference point is given, such as the heart, the proximal point of another organ or limb is the point closest to the heart, central rather than peripheral. Proximal is the opposite of distal. A more technical definition of these terms would be that the anterior (proximal) structure is at or nearer the center of the person's body and the anterior-posterior axis is perpendicular to that line. Thus, proximal structures are close together while distal structures may not be as close together. While both terms refer to the distance between something and a central point, distal can refer to what is further away. For example: your proximal structure would be that part of you that of the ground closest, and therefore more extended (think arms or toes); while your distal structures are farther from this midpoint, such as B. Your toes.
Proximal structures are closer and therefore better able to see what is happening in that area; For example, the proximal limbs feel better than the distal ones, which are farther from these sensitive areas.

Complete loss of contact between articulating surfaces. Articular cartilages are damaged, ligaments tear, and the joint capsule is distorted.
The type of joint that is least likely to dislocate is a bony synostosis.
Dislocation is a problem with the bone in the form of shifting of the bone from the joint or its proper position. Dislocations can occur in any joint, but the most common are the joints of the shoulder, finger, elbow, knee, and hip.
The main cause of dislocations is injury or trauma from a hard impact. Trauma forces joint out of place.
A synarthrosis or immovable joint is a joint that cannot move at all. As a joint, a dead joint does have a function as a connecting bone. However, this joint has no function of movement at all and tends to remain. So, the possibility of dislocation is very small.

Which of the following is most likely to decrease genetic variation?stabilizing selectiondiversifying selectionmutationdirectional selection
Option 1 is Correct. Genetic variety is most likely to be reduced by stabilizing selection.
Both inbreeding and drift decrease genetic diversity, which has been linked to a higher risk of population extinction, a slower rate of population growth, a decreased capacity to adapt to environmental change, and a decreased capacity for disease resistance, all of which have an effect on the ability of individuals who have been released to the wild to survive.
By favoring or rejecting a given gene or gene combination, natural selection can reduce genetic variation in populations of organisms (leading to directional selection). When natural selection favors an average phenotype and excludes extreme deviations, stabilizing selection reduces the genetic variance of a population.
When exposed to environmental changes, a population's genetic variation shifts toward a new phenotype, which is known as directional selection.
