if two eukaryotes participate in lateral gene transfer what will this do to the overall genetic variation of species

2 answers:

7 0

The choices can be found elsewhere and as follows:

A)nothing, the genetic variation will stay the same
B)the genetic variation will decrease
C)the genetic variation will increase
<span>D)this type of gene transfer is impossible in eukaryotes
</span>
I believe the correct answer is option C. If two eukaryotes participate in lateral gene transfer, then the genetic variation will increase. Hope this answers the question. Have a nice day.

Identify the substances that can readily pass through the inner mitochondrial membrane.

KIM [24]

Answer:

A,C E

Explanation:

The inner membrane of the mitochondria separate the matrix of the mitochondria from the cytosol(inner membrane space.). It is invaginated folded inwards to form the critae. This is an adaptive feature to increase the surface area for biochemical reaction in the mitochondria.

The invagination gives two compartments the inner mitochondria also creates the outer intermembrane space and the inner matrix

These are the substances that can pass freely the inner membrane of the mitochondria.Pyruvate and H+ can not pass through.Specifically,it is not preamble to H+ because, hydrogen ions are needed to generate the electrochemical gradients needed for the chemical energy for phosphorylation of ADP by P to form ATPs by the enzyme ATPase synthase.If the inner membrane is permeable to H+ the electochemical gradient will not be produced, and therefore ATPs productions stops.

O2 needs to pass through the inner membrane because it it the final electron acceptor. Therefore if not allowed to pass through oxidative phosphorylation and ETC will nor occur.

CO2 must pass through because its accumulation will increase the acidity of the inner mitochondria

Nana76 [90]

Answer:

Part of the extracellular matrix secreted by osteocytes. (Ans. B)

Explanation:

Cells which are present on bones are known as osteocytes. Bone is composed of extracellular matrix, and cells. There are three types of cells which are present in the bones:

1) Osteoprogenitor cells.

2) Osteoblast.

3) Osteocyte.

Extracellular matrix is composed of organic matrix consisting glycoproteins, proteoglycans, osteocalcin also known as calcium binding proteins, and osteonectin which anchors bone mineral to collagen.

1. Migration that can bring new allcles into a population.

levacccp [35]

Answer:

1. D (In population genetics, gene flow is the transfer of genetic material from one population to another.)

2. C (Genetic drift may cause gene variants to disappear completely and thereby reduce genetic variation. It can also cause initially rare alleles to become much more frequent and even fixed. When there are few copies of an allele, the effect of genetic drift is larger, and when there are many copies the effect is smaller.).

3. A and also E (Individuals with inherited characteristics that allow them to best compete for limited resources will survive and have more offspring than those individuals with variations that are less able to compete. Because characteristics are inherited, these traits will be better represented in the next generation.)

4. D (Gene flow can increase fitness but if it happens in another environment, it decreases the adaptability. If alleles are advantageous, the offsprings' inheritance increases.

5. B (Mutations are the main source of alleles)
