Answer: option C - activating second messengers and stimulating glycogenolysis and gluconeogenesis.
Explanation:
Glucagon is an hormone, produced by the pancreas, that opposes the action of insulin by stimulating the production of SUGAR.
Glucagon is usually released whenever blood glucose levels is detected to be LOW. it works by activating secondary messengers.
Answer: True.
Neonates haemoglobin level increase significantly during and following birth.
Explanation:
Neonates refers to a new born baby.
Haemoglobin is the protein in red blood cells that transport oxygen to the blood.
Haemoglobin continue to rise until two hours after birth this is because the infants require haemoglobin with high oxygen affinity which is needed for tissue oxygen and the baby might need to maximize oxygen intake following birth because its need to breath in air for respiration .
To know what happens here, you need to analyze the alleles.
If the father is color blind and the daughter is not, you can suppose that is a recessive allele.
You can tell she is a carrier only, and because we received one sexual allele from each parent. If they ask you about the gender, we can suppose a cross between Xx and XY being lower x the recessive allele (color-blind vision).
When you draw the Punnett square, you'll found the probabilities are XX, XY, Xx, and xY.
So, you have a 50% chance of having a boy and 25% chance of having a color-blind boy.
Answer:
True
Explanation:
Pulmonary circulation transports blood through the alveoli for gas exchange. In this circulation the blood that comes from the veins initially has low oxygenation, and then leaves the right ventricle of the heart through the pulmonary artery, enters the lungs and returns to the heart with arterial and oxygenated blood
The bronchial circulation is well oxygenated and provides oxygen to the lungs. The structures to which this oxygen contributes in lungs are those that do not participate in a gas exchange.
