The probability that their next child will have polydactyly is 0.75

<h3>What is Polydactyly?</h3>

Polydactyly may be characterized as a circumstance in which an individual has more fingers or toes as compared to normal.

In humans, it occurs due to the homozygous mutants for a HOXD13, and due to which digits are joined and a condition known as Polysyndactyly occurs.

If both parents carry the genotype heterozygous for Polydactyly, i.e. Pp, the resultant offspring will have the genotypes PP, Pp, Pp, and pp. In which pp is normal, while all the three are affected due to the expression of dominant allele causing Polydactyly.

Now, according to the question, only one of the offspring possess the genotype of pp, hence the probability of their next child will have polydactyly is \frac{3}{4} = 0.75.

Therefore, the probability that their next child will have polydactyly is 0.75.

How is it possible for a baby to grow all of its<br> organs
avanturin [10]

Explanation:

during the embryonic stage the baby grows its organs

Nervous system. This is one of the first things that develop. It includes the formation of the baby’s brain, spinal cord, and nerves.

Heart. An S-shaped tube forms on the front of the embryo. This will become the baby’s heart. At first the heart does not beat, but soon it starts beating and pumping an early form of blood.

Face. The baby’s facial features begin to take shape. The eyes and ears form. The eyes move forward on the face, and eyelids form. Pieces of tissue grow and join together to create the forehead, nose, cheeks, lips, and jaw. The nasal passages, mouth, and tooth buds form the baby’s first teeth. A tongue with taste buds also forms.

Arms and legs. At first, the baby’s arms and legs begin as little buds that sprout from the embryo’s sides. As they grow, the arms look like paddles and the legs look like flippers. A ridge appears on the end of each one. They eventually become the baby’s fingers and toes.

Sexual organs. Cells form to become the baby’s eggs or sperm. The baby’s private parts (girl/boy) is visible at the end of the embryonic period.

Muscles and movement. Muscles develop and the embryo begins to move. At first it’s only twitching and reacting to touch. Once the nerves and muscles start working together, the baby can start moving on purpose.

Superficial region around the renal medulla
nalin [4]

Answer:

Renal cortex

Explanation:

The renal medulla of a kidney is surrounded by renal cortex. The renal cortex is the granulated layer. It is the renal cortex in which the renal corpuscle (glomerulus and Bowman's capsule) are present. The renal cortex is reddish brown in color. This is due to the fact that most of the renal arteries deliver the blood to the cortex.

Compared to a cell with few aquaporins in its membrane, a cell containing many aquaporins will A. have a faster rate of osmosis
Aloiza [94]

The correct option is A: have a faster rate of osmosis

A cell containing many aquaporins will have a faster rate of osmosis.

Aquaporins are micro water channels within the membrane that allow for the exchange of water and other neutral molecules over the biological membranes of other organisms.

Due to the presence of Aquaporins in plants, they have a high diversity of regulation properties, localizations, and transport selectivity.

The rate of osmosis increases as the aquaporins facilitate the transfer of water at a faster rate.
