Answer:
Rubber on steel and Rubber on dry concrete
Explanation:
Friction is the force of resistance on the solid motion surfaces.
Coefficient of The ratio of frictional force between two body and the forces that brings them together. It depends on the temperature, velocity of the object involved.
Rubber is said to exhibit a high coefficient of friction with other surface ranging from 1 to 2 while Dry surface material yield between 0.3 to 0.6. When friction is greater than 1 it means the force that is needed to slide or move an object on the surface is greater than the force that exist on the surface of the object.
The answer is C, Glycolysis
A phylogenetic tree is the representation of the evolutionary relationships among species. The fossil records are used as evidence to develop a phylogenetic tree. Thus, option A is correct.
<h3>What is a fossil record?</h3>
A fossil record is a depiction of the organisms that shared common ancestors and depicts the change in the structural and functional unit of the organism over many years of time.
They are used to illustrate the phylogenetic tree to show the morphological, structural, chemical, anatomical, etc variations in species that shared ancestry.
Therefore, option A. fossil records are used to show the common ancestry at the nodes.

Answer:
Explanation:
Ccrm is a DNA methyl transferase. This enzyme helps in switching from fully methylated stated to hemimethylated state at its target motif. In this way this gene helps in expression of genes which helps in controlling the cell cycle progression.
When the Ccrm gene is found to be non functional in form. Then there is no switching occur from fully methylated to hemi methylated state at its target motifs. That's why there is not found expression of those genes which are involved in the cell cycle progression. In this way there is not found replication of DNA and there is not found replication of chromosome. That's why there is found single chromatid containing chromosome even after S phase. That's why the daughter cell will not get equal amount of genetic material. And cell cycle becomes futile.
A. Turner syndrome.
Turner syndrome is a type of aneoploidy called monosomy, which causes the person to be born with only one X chromosome with no extra Y or X.
