I am pretty sure it is B. This behavior is an instinctive behavioral sequence and it inevitably runs into completion which means it cannot be stopped. Hope this answers the question.

The PCR primer ‘D7S820’ is used to amplify the D7S820 locus. Using this gel below, determine whether each person (M1, P1, P2, C1
Ahat [919]

Answer:

1) M1 is heterozygous since it contains 2 bands, which means that it contains one recessive and one dominant allele

P1 is homozygous for this locus, since it contains a single band or is known to be homozygous for the locus or gene.

P2 is hetozygous for this locus because two bands appear in which each band represents one allele for the gene.

ChildC contains two gel bands, representing two alleles and is therefore heterozygous

P1 is the father of the child C1, if we look at the gel, each father shows a similar band, one coinciding with the mother and the second with the father p1

As for the paternity study, the PCR test is not useful, since it provides asymmetric results, thus only one strand information will be provided, and because the DNA is double-stranded, a more complete study is required.:

A zebra mussel is discovered in a lake in Pennsylvania for the first time. Why would this make an ecologist worried?
Anna71 [15]

If a zebra mussel is discovered in a lake in Pennsylvania, then the ecologist would be worried because it is an invasive species. The zebra mussel is native to Ukraine and Russia, but if it has been found in Pennsylvania, than it means that it has been introduced in this area. As an invasive species, the zebra mussel can be very dangerous for the native species in the lake. The invasive species usually are more competitive for food sources than the native species, manage to reproduce quicker, bring in diseases, and the native species tend to not have defense mechanisms for them. This leads to rapid decline or even extinction in the native species, while the invasive spreads out quickly and takes over, resulting in dramatic change in the whole ecosystem.

The earliest mammals were very small and shrew-like. True or False
jek_recluse [69]
{I got this from online hope it helps}The earliest known mammals were the morganucodontids, tiny shrew-size creatures that lived in the shadows of the dinosaurs 210 million years ago. They were one of several different mammal lineages that emerged around that time. All living mammals today, including us, descend from the one line that survived. So yeah it’s true

A joint capsule (articular capsule) has two layers. the function of the capsule's internal layer is to?
Scorpion4ik [409]

The function of the joint capsule ( articular capsule ) is to produce synovial fluid.

The joint pill presents passive joint stability, proscribing the joint range of motion, mostly via the tough, fibrous outer layer. The capsule also affords nutrients and lubrication to the joint via the internal synovial layer.

The articular capsule additionally includes two layers

  • The outer fibrous membrane which could incorporate ligaments and
  • The internal synovial membrane that secretes the lubricating, shock-soaking up, and joint-nourishing synovial fluid.

The joint pill, ligaments, and tendons serve to stabilize the joint, distribute the biomechanical load at the joint and shield the joint through proscribing its regular variety of movement.

It includes two layers, an outer fibrous layer and an inner layer known as the synovial membrane. also called the synovium, it includes a synovial lining and the assisting stromal tissue. It produces synovial fluid that lubricates the joint. The fibrous outer layer of the articular tablet improves joint balance.
