1. <span>The North Star, or Polaris, is the brightest star in the constellation Ursa Minor, the little bear (also known as the Little Dipper). As viewed by observers in the Northern Hemisphere, Polaris occupies a special place. The point in the night sky where the projection of the earth's axis lies is known as the North Celestial Pole (NCP). As the earth rotates on its axis (once every 24 hours), the stars in the northern sky appear to revolve around the NCP. Polaris lies roughly one half degree from the NCP, so this particular star appears to remain stationary hour after hour and night after night.                     2.</span>

Kamila [148]

The statement that best explains why Chris did not get a rash from the water was that Chris's medication has an antagonistic relationship with the toxin in the water. That is option B.

<h3>What is drug-drug interaction?</h3>

Drug-drug interaction is definitely as the relationship that exists between two drugs when administered together or at the same time.

This relationship that exists between the drugs could be:

  • Synergistic relationship or

  • Antagonist relationship.

A synergistic relationship is the type of relationship that occurs between two drugs where by the total effect of the drugs are greater than the sum of the individual effects of each drug.

An antagonistic relationship is the type of relationship that occurs between two drugs where by the both drugs has opposite effects on the body.

Therefore, Chris didn't have the rash because his medication has an antagonistic relationship with the toxin in the water.

Coin tosses can demonstrate the effects of genetic drift. Imagine that heads and tails are two alleles in a population. Consider
nydimaria [60]

Answer:

Smaller populations have a greater chance of having one allele expressed disproportionately.

Explanation:

Genetic drift corresponds to a drastic casual alteration of the natural order, reaching the genotypic concentration of one or several species, not preliminarily involving natural selection factors, but caused by sudden events.  Such phenomenon is characterized by the occurrence of ecological catastrophes, for example: earthquakes, tsunamis, tornadoes, floods, burnings, avalanches and other processes, affecting a large population contingent. Thus limiting the genetic content of a particular group, restricted to the prevailing individuals.

In this situation, with low variability, differentiated individuals will experience a more significant selection pressure in relation to the ascending lineage, which minimized the achievements of selection due to the high number of living individuals. In this scenario, smaller populations will have a greater chance of having a disproportionately expressed allele as the number of members is reduced. We can also see this effect if by using a coin we imagine that heads and tails are two alleles in a population and each coin toss represents one member of that population.

Reticulate and elementary bodies are two forms of A. Mycoplasma. B. Caulobacter. C. Chlamydia. D. Myxobacteria.
Aleksandr [31]

Answer:

C. Chlamydia. is the correct answer.

Explanation:

Chlamydia is a bacterial sexually transmitted disease, caused by obligate intracellular Chlamydia trachomatis.

In the life of chlamydia, there are two stages of developmental(Reticulate and elementary bodies are two forms of Chlamydia.)

The elementary body is the infectious substance, they are non replicating and have a rigid outer membrane that binds to the receptors present on the host cell and it initiates the infection and due to the rigid outer membrane there, no fusion between the phagosome and the lysosome hence oppose the intracellular killing.

Reticulate bodies are the metabolically active form of a chlamydia and non-infectious.
