Answer:
PpDD and PpDd
Explanation:
Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d).
The <u>possible genotypes of a pigment-eyed, dimple-chinned person</u> would be PPDD, PpDd, PPDd, PpDD while a blue-eyed person without a dimpled chin would have the genotype ppdd.
The genotype of a blue-eyed, dimpled chin child would be either of ppDd or ppDD, but in this case, the mother is ppdd and as such, the child cannot have two copies of D allele. Hence, the genotype of the child can only be ppDd.
In order for the child to have blue eyes (pp), it means that the father has to have the non-pigmented allele (p). This also means that the father is heterozygous for eye pigmentation (Pp).
<em>Hence, the genotype of the father is now limited to </em><em>PpDD</em> <em>and </em><em>PpDd</em>.
In most cases, the two major climatic factors affecting the distribution of organisms in terrestrial ecosystems are the amount of water and temperatures. Terrestrial ecosystems rely on the sun's energy to support the growth and metabolism of the organisms. Plants use the sunlight, then they supply the organisms that are higher up the food chain with energy and the structural buildings blocks of life. Water is also essential for the survival of these organisms.
Explanation:
Results in a decline in CD4+T cell numbers below the critical level, and loss of cell-mediated immunity. Therefore the body becomes progressively more susceptible to opportunistic infections and cancer.
Answer:
C
Explanation:
The environment lapse rate calculates the rate whenever the atmospheric temperature decreases and the altitude increases and so dose the temperature because that are uniformly the same
The pathway between the ventral tegmental area (VTA) and the Nucleus Accumbens is critical for the addiction process because lesions to this pathway eliminate addiction. It is a part of the brain.
<h3>What is the nucleus accumbens?</h3>
The nucleus accumbens refers to a part of the forebrain located in the hypothalamus.
The nucleus accumbens is an interface between motivation (i.e., stimuli) and the corresponding action (response).
The nucleus accumbens is fundamental in different responses such as, for example, rewards, stressful situations, drug behavior, etc.
