The skin of the newborn is very thin,and it has a special form of regular temperature that is made by the metabolism of the so-called "brown fat". Brown fat is a special fatty tissue of the newborn that has a high capacity to produce heat through chemical reactions. The fat is distributed in different parts of the baby's body.
Answer:
The correct answer will be 2 gametes with 29 chromosomes and 2 gametes with 27 chromosomes will be formed.
Explanation:
Meiosis is a type of cell division which produces four daughter cells. Chromosomes separate or the disjunction of chromosomes takes place during anaphase I and anaphase II of meiosis I and II respectively.
If a chromosome fails to disjoin at meiosis I this will result in the production of four gametes with an unequal number of chromosomes. Out of four gametes, 2 gametes produced will be trisomic gametes that are with one additional copy of chromosome and 2 gametes will be monosomic with one less number of chromosome. It means the trisomic gametes will have 29 chromosomes while 2 monosomic gametes will have 27 chromosomes.
Thus, 2 gametes with 29 chromosomes and 2 gametes with 27 chromosomes will be formed is the correct answer.

Answer:
Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.
Explanation:
Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.
Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.
Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.
Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.
