Greg is much taller than either of his parents. This is partly because he has inherited ancestral genes that may not have been e

xpressed in either of his parents' phenotypes and partly because the outward expression of height is affected by a multitude of genes that each contribute a small amount. This latter genetic effect is best described as: a. dampening. b. dominant–recessive. c. additive. d. X-linked.

Answer: Option c is the answer.

Additive.

Explanation:

Additive genetic effect is a form of genetic effect that occur as a result of when two or more genes contributes to the final phenotypic expression. It is when alleles of a gene combine to contribute to the summation of their individual effects.

Therefore, the gene effect is additive because many alleles contribute to the effects of Greg tallness.

Hypertension is most commonly known as high blood pressure, which is condition where the blood in a persons arteries are abnormally high. high blood pressure/hypertension can be lowered by maintaining a healthy lifestyle. this means that you must exercise regularly and eat well, which tells us that option B and D are incorrect. hypertension is also known to cause heart attacks if it is left untreated for long periods of time and can occur if you are being treated for heart disease, but heart disease is usually never the cause of hypertension. since we have determined that option C is also incorrect,, we a left with option A as the correct answer to this question. having hypertension can be genetic, so if you have two parents who are genetically prone to this condition you are more likely to have it.

Meiosis consists of ______round(s) of dna replication accompanied by _____ rounds of cell division.
Licemer1 [7]
<span>Meiosis consists of one round of DNA replication accompanied by two rounds of cell division.
Before meiosis starts, the cell </span><span>goes through an interphase period in which it grows, replicates its chromosomes to have enough material to divide for the daughter cells.
Unlike mitosis, meiosis has 2 cell division (meiosis I and II). At the end of the first division, </span><span>each cell has half the number of chromosomes of the parent cell. At the end of the second division</span> there is separation of the sister chromatids

What would make a hypertonic solution isotonic
natulia [17]
Isotonic, Hypotonic, and Hypertonic Solutions. Water moves readily across cell membranes through special protein-lined channels, and if the total concentration of all dissolved solutes is not equal on both sides, there will be net movement of water molecules into or out of the cell.

Indirect methods like mark and recapture become a strong tool to estimate population size or density in species on which it is impossible to apply a direct methods. <em>Because of their biological and ecological characteristics, the Gypsy moth and the Green lizard populations are good examples  for which  mark and recapture would work well.</em>

<em>------------------------------------------------------</em>

There are different methods to study population density. There are direct methods and indirect methods. Among these last ones, we might find the Mark-Recapture technique.

The Mark-Recapture technique assumes that

  • <em>the population is closed during the sampling season, there is no mortality nor natality, </em>
  • <em>marks in the individual last the whole sampling season, and they do not affect the marked individual or their behavior. </em>
  • <em>marked individuals are randomly distributed in the population, and </em>
  • <em>all the individuals have the same probability of being sampled.</em>

The method consists of capturing a sample of individuals belonging to the population under study. After capturing the individuals, the researcher marks and releases them again. The third step is to sample again: The researcher captures new individuals and counts how many of them are marked. These marked individuals belong to the first sample.

Indirect methods like this become a strong tool to estimate population size or density in species on which it is impossible to apply a direct method such as <em>counting individuals</em>.

For instance, if we need to estimate insects population density (<u><em>Gypsy moth population</em></u>) or reptiles population density (<u><em>Green lizard population</em></u>) because of their biological and ecological characteristics, the best way of doing it is by applying indirect methods. <em>These species characterize as small-sized, fast to escape, they can hide in small inaccessible places, they have nocturnal habits, their reproductive rate is too high, and their distribution rate is wide. </em>Among many other characteristics, their population density can not be estimated by direct methods. Mark-Recapture technique is the most suitable one.
