Answer: Components of cell junctions

Explanation:

<u>Fibroblasts are cells located in the dermis,</u> responsible for the formation and remodeling of tissue. They synthesize fibers and maintains the extracellular matrix of the tissue of animals. So, t<u>he extracellular matrix is a structurally complex entity that surrounds and supports the cells found in tissues</u>.

A cell junction a structure that exists within the tissues of animals and they consist of protein complexes that provide contact between cells or between a cell and the extracellular matrix. So if the cells do not appear flattened and do not attach to the extracellular matrix, then there is a problem with the components of cell junctions, which are mostly proteins as it was said before. And since proteins are coded by genetic information stored in DNA, then if there is a mutation in any of those genes, the fibroblast will fail to attach because the protein of the cell junction will be abnormal.

When the polymerase chain reaction (PCR) is used to amplify segments of DNA, the sample is first heated, and then cooled, in cyc
baherus [9]

Answer:

At least 17 PCR cycles or 16 PCR cycles

Explanation:

As we know -

In one chain of  heating and cooling  of polymerase chain reaction (PCR), the strands of DNA gets doubled.

The general mathematical representation of this is

{2^n - (2 *  n)}

where "n" is the number of PCR cycles.

It is given that DNA strands  to be produced is 16 times the original quantity of DNA.

So the PCR cycle must be carried out at least 17 times in order to have DNA strand not less  than 16 times the original quantity of DNA

According to this article, why does the immature prefrontal cortex lead to<br> conflict for teens?
aivan3 [116]

Answer:

The immature prefrontal cortex lead to  conflict for teens because the teenagers when they try to use the frontal lobe for reasoning, they tend to overdo it and then giving their brain much work to do. This leads to conflict in teens.

Explanation:

In teens, the prefrontal cortex is immature and develops until the mid-20s of their age. It covers the front part of the frontal lobe. As a result of the immaturity of the prefrontal cortex in teens, they do not think or make decisions like that of adults. When they try to overdo with their immature prefrontal cortex, they end up in conflicts.

In this lab, the three flocks of birds changed in numbers between generation 1 and generation 3. Why? Check all reasons. The amo
anyanavicka [17]

Working in a lab means working under controlled environment. If in the generation 1 and generation 3, the number of bird’s increases or decreases in number, the possible conditions for this would

- The amount of food increased or decreased

- If a flock’s beak type made it easier to pick up the available food, the flock grows and vice versa

Justification: if the beak type for generation 1 makes the food intake easier, it will grow which ultimately decreases the food for the generation 3 which has un-supportive beak type.
