<span>A primipara is a woman who is giving birth for the first time - that is, she is a first time mother and is not going to give birth v aginally after cesarean (known as a VBAC). The lacerations that could be experienced during birth are natural and typically occur to the area between the v agina itself and the a nus. These lacerations are rated according to how severe they are, with a second-degree laceration being one that has actually gone beyond a slight tear in the skin and is now injuring the muscle tissue underneath. The most common complication of these second-degree lacerations after birth is a weakening of the muscles that allow one to p0o; persistence of this problem or an acquisition of postpartum fecal incontinence should both be assessed by a doctor.</span>
It takes an extremely high temperature for nuclear "fusion" to occur inside the sun, since this is the dominant source of energy as opposed to nuclear fission, which also takes place but at much smaller levels.
Answer:
Please see below
Explanation:
The reason behind this is the phenomenon of natural selection. The deleterious mutations do not provide a survival advantage so they are selected against, which results in these type of mutations to not be passed on - rather, they eventually get eliminated from the population.
The fossilized fish which is found has jaws but no true bones belonging at point B on the Cladogram. Thus, the correct option is B.
<h3>What is Cladogram?</h3>
A cladogram may be defined as a phylogenetic tree that is based on the classification of evolutionary relationships.
In the given cladogram, D is any ancestral point from which speciation occurs. Point C is a basal taxon while A and B are sister taxons.
The organisms of point B have only jaws bu,t not true bones, while the organisms at point A have both jaws and true bones.
Therefore, it is well described above.

Unicellular organisms are devoid of circulatory systems and will be found living in moist or watery environments to facilitate uptake of nutrients and gases and expulsion of waste by the process of diffusion.
Their cell is structured such that it can engage in direct exchange of substances with its environment. Water serves as the perfect medium or environment through which this exchange can occur.
Gases and nutrients simply diffuse into the cell or are moved into the cell by means of active transport or phagocytosis.
