How is a fetus able to extract O2 from its mother's blood?

Biology

Reil [10]3 years ago

Answer:

E.

Explanation:

A fetus is able to extract O2 from its mother's blood because fetal hemoglobin has a higher affinity for O2 than maternal hemoglobin. Thus making it alot easier for the hemoglobin to bind to oxygen. This causes the oxygen-dissociation curve to move towards the left of the maternal oxygen-dissociation curve.

Answer:

E. Fetal hemoglobin has a higher affinity for O2 than maternal hemoglobin.

Explanation:

Hemoglobin is a protein found in the blood which is responsible for binding to oxygen for efficient circulation to other parts of the body.

Fetal hemoglobin is usually at a high level and it’s produced around 6 weeks of conception. The fetal hemoglobin has a higher affinity for Oxygen than that of the maternal hemoglobin and it helps in carrying oxygen from the bloodstream of the mother to cells and tissues of the fetus.

If a local population of a species goes extinct, which of the following outcomes is/are possible?a. Genetic variation may be los
insens350 [35]

Answer:

a. Genetic variation may be lost from the species as a whole

d. The overall adaptive prospects of the species may decline.

Explanation:

Genetic variations are heritable traits possess by the offspring from it progenitors. This makes the offspring to be an hybrid species because it has inherited the traits of both of his/her parents. In a local population setting goes to extinct, it might be as a result of genetic variation because these inherited variations comes in several ways, some might be adaptability to thrive in adverse weather  conditions, some production of specific hormones to combat the current state that its not suitable for them etc. so when a population shows a decline in genetic variation, such population is liable to extinction.

Also, when species can't cope with factors attached with adaptation to a particular ecosystem, (such as exhibiting camouflage in  time of danger, during dry season when food scarcity has increased etc) there will be decline in population of the species.
