<span>A mirror neuron is a neuron that fires both when an animal acts and when the animal observes the same action performed by another. Thus, the neuron "mirrors" the behavior of the other, as though the observer were itself acting. Such neurons have been directly observed in primate species.</span>

You are an expert paleontologist reviewing the work of Professor Bonefinder, who recently discovered the remains of a primate fo
sergeinik [125]

Answer:

The professor Bonefinder has made a mistake.

Explanation:

I't is true the Hominoid had a long snout, a large orbits that are partially enclosed, but they have no tail. This point is really critical because the morphology of an species is really important. The taxonomists use the information that morphology gave for many years to identify species, nowadays with molecular techniques some of those species are pulled apart, but the important matter is that hominoids had no tail.

So the professor Bonefinder analysis is incorrect because the hominoids have no tail.

PLEASE HELP!! 36 POINTS!!!

Answer:

Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.

Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).

Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).

Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.

Introduction

We've already met a few different mechanisms of evolution. Genetic drift, migration, mutation...the list goes on. All of these mechanisms can make a population evolve, or change in its genetic makeup over generations.

But there's one mechanism of evolution that's a bit more famous than the others, and that's natural selection. What makes natural selection so special? Out of all the mechanisms of evolution, it's the only one that can consistently make populations adapted, or better-suited for their environment, over time.

You may have already seen natural selection as part of Darwin’s theory of evolution. In this article, we will dive deeper – in fact, deeper than Darwin himself could go. We will examine natural selection at the level of population genetics, in terms of allele, genotype, and phenotype frequencies.

Quick review of natural selection

Here is a quick reminder of how a population evolves by natural selection:

Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers.

If this continues over generations, the heritable features that aid survival and reproduction will become more and more common in the population.

The population will not only evolve (change in its genetic makeup and inherited traits), but will evolve in such a way that it becomes adapted, or better-suited, to its environment.

Why are telomeres problematic for eukaryotic chromosome replication? a) They are highly repetitive and thus hard to replicate co
Natalka [10]

Answer: Option E

Maintaining very long telomeres promotes cancer cell formation.

Explanation:

Telomere refers to either of the sequences of DNA at each end of a eukaryotic chromosome.

Usually, in eukaryote chromosome replication, telomeres are not replicated.

Hence, they are usually lost resulting in the shortening of the telomere ends after repeated cycle of cell division. This also leads to cell aging and stoppage of cell division.

The shortening of telomere combined with stoppage of cell division, and cell aging initiation prevent CANCER, which thrives on lengthy telomeres
