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.

What are Intramembranous and endochondral ossification?
erma4kov [3.2K]

Answer:

The direct conversion of mesenchymal tissue into bone is called i<u><em>ntramembranous ossification</em></u> .The process by which a cartilage intermediate is formed and replaced by bone cells is called <em>endochondral osssification.</em>

Explanation:

Intramembranous ossification  is one of the two essential process during the fetal development  of the gnathosome skeltal system by which rudimentary bone tissue is created. It is the process of bone development from fibrous membranes. It is involved in the formation of the flat bones of the skull, mandible and the clavicle. This type of ossification also helps in healing of bone fractures.

Endochondral Osssification: Method of forming a bone through cartilage intermediate. It is also involved in the formation of long bones.

Q4.15. The following statements describe four distinct types of evidence that climate scientists
Tema [17]

Answer:

C

Explanation:

In this question, we want to select which of the options that correctly attributes recent changes in climate to human activities

The correct answer is that global climate models can only reproduce recent temperature increases when anthropogenic green house gas emissions are included as forcing

What we have here is that for the models to show a pattern of temperature increase that we have seen recently, there must be a substantial effort by humans to have increased green house gases emission as a direct result of their activities

So this clearly put in the pattern detection of temperature increase by the model as a result of human actions thereby directly attributing what the model has developed as a result of what men has put into action
