Biology

Mashutka [201]2 years ago
6 0

Answer:

1.A number of genes have been positively associated with the skin pigmentation difference between European and non-European populations. Mutations in SLC24A5 and SLC45A2 are believed to account for the bulk of this variation and show very strong signs of selection.

2.Cancer can circumvent negative selective pressures due to its ability to accumulate mutations that cause genetic diversity in tumor cells as the cells proliferate. Cancer seems to have evolved a propensity for, or at the very least, a selection for fitness.

3.Folate levels decrease depending on sun exposure, study says. 05 Feb 2019 --- Folate levels decrease during the months when solar radiation is higher and ultraviolet radiation proportionately affects folate levels in the blood.

What are the cause.s of monocultures,loss of topsoil.alien species
kirza4 [7]

The causes of monocultures are the economics of global product of agriculture, standard of industrial society, and the apparent “simplicity” of managing only one crop.

The major cause of the loss of top soil is soil erosion (which is caused by the factors like water, wind and tillage of farm fields). Loss of top soil become a global problem for agriculture.

<span>A species that are occurring outside of its normal distribution are known as Alien species. The cause of alien species is that these species are not native to ecosystem and they can cause harm to the environment.</span>

In eukaryotes, how can a single gene code for several different proteins?
NikAS [45]

Answer:

Gene splicing is a post-transcriptional modification in which a single gene can code for multiple proteins. Gene Splicing is done in eukaryotes, prior to mRNA translation, by the differential inclusion or exclusion of regions of pre-mRNA. Gene splicing is an important source of protein diversity.
