Answer:

Epigenetic phenomena

Explanation:

Epigenetics involves the changes in gene expression which is not as a result of changes in an individual's DNA sequence. In other words, it is a change in an individual's phenotype, without an alteration in the genotype.

It is involved in the normal functioning of cellular processes.

Examples of epigenetics is DNA methylation ( adding of a methyl group to a section of the DNA molecule) and histone modification such as histone acetylation (adding an acetyl group to the histone).

Epigenetic changes can switch off genes, hence, prevent the expression of those genes; it can also turn on genes, hence increase the expression of those genes.

Epigenetic changes can also results to diseases such as cancer.

Answer:

Epigenetic phenomena

Explanation:

Epigenetics is the external changes to DNA that can turn genes on or off. The changes does not affect the DNA sequence, but it affects how cells read genes.

Epigenetic changes affects the physical structure of DNA by altering it. DNA methylation and histone modifications are examples of epigenetic changes.

DNA methylation: this is the addition of a methyl group to part of the DNA molecule, it prevents the expression of certain genes.

histone modification: Histones are the proteins that DNA wraps around. DNA would be too long to fit inside cells without this protein. If DNA is squeezed tightly, then the cell cannot read the DNA. The DNA can be accessible to proteins that read genes through changes that relax the histone.

Epigenetics is what makes a skin cell, a brain cell or a muscle cell look different. Though these three cells have the same DNA, their genes are expressed differently, which causes the creation of the different cell types.

Ksju [112]

Answer:

Yes.

Explanation:

Energy can always be transformed from one form to another form.

E.g. Throw a ball in upward direction ,so it will have some kinetic energy due to its mass and velocity. At some height ball will stop and will start coming down.

Santos and Lüderitz are the same distance from the equator, and both cities
Hoochie [10]

Answer:

The difference in altitude between these two regions.

Explanation:

As you can see in the question above, Lüderitz and Santos are two regions that are the same distance from the equator, which indicates that the two regions have the same latitude and are in tropical zones. In addition, the two regions are close to the ocean, but the air in Lüderitz is cooler.

This indicates that there is a difference in altitude in these regions and Lüderitz has a higher altitude than Santos, which is why Lüderitz's air is colder and Santos's is hotter.

Altitude is a geographic term that represents the distance of a region in relation to the level of the sea. The higher the altitude, the greater the distance.

The higher the altitude of a region, the colder its air will be. This is because in high altitude regions, air is thin and has a small capacity to retain heat.

Quorum sensing is triggered to begin when ___________.
Lilit [14]

Answer:

Quorum sensing is triggered to begin when<u> a sufficient number of bacteria are present .</u>

Explanation:

Quorum sensing -

Quorum sensing is the ability to detect and to respond to the cell population density by the process of gene regulation . Quorum sensing bacteria releases some chemical signal molecules called the autoinducers , that increases the concentration as the function of the cell density .

The detection of the minimum threshold concentration of an autoinducer leads to the alteration in the gene expression .
