Answer:
The correct answer is A.) Sister chromatids are pulled apart.
Explanation:
This is because during Anaphase II in Meiosis, the sister chromatids are pulled apart.
Chromosome pairs line up during Prophase I. <em>Not B.</em> When the chromosome pairs pair up this is also Metaphase I. <em>Not C.</em> When chromosome pairs are pulled apart, Anaphase I is occurring.

Black B is dominant over chestnut color b and trotting gait T is dominant over pacing gait t. The answer is 100%. Since all offspring have at least one dominant black hair allele that overwhelms the brown hair allele, all offspring are expected to have black hair.
Phenotype refers to the physical color of a horse's coat or the way genes are expressed. Phenotype II FMF in Familial Mediterranean Fever is the onset of amyloidosis prior to the onset of his FMF with typical attacks or is an isolated finding in members of the FMF family.
White horses have pink skin. White fur mane tail, and hooves. and dark brown eyes. White is the dominant trait W at the white locus. White horse genotype must be heterozygous dominant We. Homozygous dominant because WW is more likely to cause early embryonic loss. Scientists conclude that horses were first domesticated 6,000 years ago in the western part of the Eurasian steppe, in what is now western Ukraine and Kazakhstan.

Answer:
The answer is "Option C and Option D"
Explanation:
FRAP is used only for protein motion management. It travels throughout two dimensions in the plasma membrane. It includes many available-moving or immobile proteins. This technology uses globally marked fluorescent bleaching products, and also includes the fluorescent proteins, but one particular area is washed.
Its protein arc changes are detected by fluorescence reappearance. The fluorescence reappears at a certain stage if the protein can move freely.
When the proteins aren't able to move quickly, fluorescent dyes are recovered after a little period, and fluorescence would not resurface during that point if the enzyme is immobile.
Answer:
Naturalists noted that in contaminated industrial areas, contrary to what happened in non-industrial areas, dark forms predominated over clear ones. Why do dark variants leave more descendants than light ones? As soon as we analyze the ecological niche of this species a little, we realize that there are many interactions of all kinds that can determine the biological efficacy of a moth. The ability to capture food, the avoidance of predators, the success in the mating of the males, the fecundity of the females, etc., can be some of the factors. Perhaps dark-colored females are more fertile than light ones. It seems unlikely, however, that there is a relationship between the degree of pigmentation of the body and the number of eggs that a female can leave. Perhaps dark males are more successful in mating than light males. It's possible. A significant fact is that the soot of the factories kills the gray-light lichens that inhabit the bark of the trees, where these moths spend much of their time, and blacken it. This evidence suggests that perhaps dark forms are less conspicuous in the environment in which they develop (the bark of trees) than clear ones, so that predators (birds) preferentially capture the latter. Following this reasoning, the British H. B. D. Kettlewell carried out a series of experiments that demonstrated that dark forms camouflage themselves better than predatory birds than clear ones in tree bark, being favored by selection. Therefore, the dark color is an adaptation because its carriers survive longer - they are less predatory - than those of light color. The adaptations, those properties of the organisms that so often fascinate us, are those characteristics that increase their frequency in the population due to their direct effect on survival or the number of descendants of the individuals who carry it. Adaptations are thus an intrinsic product of natural selection. What determines that a variant is an adaptation? The ecological context of each population. Thus, while dark forms are favored in contaminated areas, light forms, on the contrary, are mimetic in uncontaminated areas, being here those selected in favor. Adaptation is not an invariable, or absolute, but contingent property, a function of each ecological context. There is no a priori a phenotype, a clear or dark, better. We must always go to the ecological context of each species to know the cause of an adaptation. And this is another essential aspect of Darwinism, the contingency of its products, its dependence on the environmental contexts through which species pass through their evolutionary history and which are unpredictable.
