Answer:
Membrane B, because it is composed of unsaturated fatty acids that have one or more bends, which prevent tight packing.
C- Section, also known as a caesarean section.
Explanation:
Incomplete dominance is an intermediate effect of the dominance where the allele for a trait does not express its complete effect of a paired allele as a result both the alleles show their equal effect on the trait.
The generations are produced having a third trait as observed in the case of snapdragon flowers. In the case of flowers
The allele which
1. Determines the red color will be- R
2. Determines the white color will be- r
The monohybrid cross will have parents with genotypes:
1. Red flower- RR
2. white flower-rr
The F₁ generation will have offsprings with genotype-
RR X rr = Rr (Pink flower)
The F₂ generation will have offsprings with-
Rr x Rr= RR, Rr and rr.
Answer:
Breathing rate is most likely to increase if the blood level of carbon dioxide increase.
Explanation:
Breathing rate is the number of breaths of a person during a specific time, is usually the number of respiratory cycles that occur per minute. External respiration is the process of exchanging oxygen and carbon dioxide from the outside of the human body to pulmonary capillary blood. Once in the lungs, oxygen (and carbon dioxide to a very small extent) through the alveoli, pass into the red blood cells of the pulmonary vein blood. Carbon dioxide reacts in the blood with water, thanks to an enzyme, giving rise to bicarbonate. Blood reaches the heart, and is pumped into the cells by systemic arteries. The oxygen in the blood crosses the cell membrane and in turn, an exchange occurs, since the cell expels carbon dioxide and oxygen that it has not used. Once the exchange is done, the blood is conducted through the systematic veins with oxygen whose partial pressure is lower, and with an increase in the partial pressure of carbon dioxide. It reaches the heart again, leads through the right atrium and ventricle and finally travels through the pulmonary artery to the lungs where the air is expelled (expiration). Breathing rate tends to increase when the level of carbon dioxide in the blood increase.
