In humans, the embryonic and the fetal forms of haemoglobin have a higher affinity for oxygen than that of adults this is because non-identical genes produce different versions of globin during development. So the correct option is A.
<h3>What is meant by oxygen affinity? </h3><h3> </h3>
The amount of oxygen delivered to the cells will depend on the haemoglobin's oxygen affinity.
Oxygen affinity is defined as the relationship between the saturation of haemoglobin oxygen, represented by SaO2 and the oxygen tension, represented by PaO2. This relationship is plotted by a dissociation curve which is S-shaped.
Thus, in the embryonic the fetal form, haemoglobin has a higher affinity for oxygen.
Therefore the correct option is A.

If a woman with vaginal bleeding reports syncope, the EMT should assume that she "is in shock".
<u>Option: B</u>
<u>Explanation:</u>
The most common form of syncope is the Vasovagal syncope. It is triggered by a dramatic drop in blood pressure, resulting in a decline in blood flow to the brain. When one stand up, gravity causes blood to settle down below one's diaphragm, in the bottom part of their body.
It is a component of a wider class of medical conditions which may lead in TLOC involving postural orthostatic tachycardia syndrome (POTS), orthostatic hypotension and neurologically mediated syncope (NMS). The overlapping of such clinical symptoms causes confusion about the category of syncopes which may complicate assessment approaches and present difficulties for diagnosis and treatment, especially in young women.
It prevents water evaporation.

Answer:1
1. It can be use as source of energy and fuel.
2. It can be use to build body tissues and bones.
3. To fight pathogens or fight infections.
4. It can be use for bones development.
Explanation:
Biomass are Renewable source of organic matter that can be use for energy. These includes wood, seaweeds, crops and animal wastes. Biomass get it's source of energy from sunlight. All biomass contained stored energy from sun which is gotten from the process of photosynthesis where green plants uses carbondioxide and water with light energy to produce sugars. Animals get their energy from consuming sugars.
Biomass eaten by animals can be use in four ways.
. It can be use as source of energy and fuel.
2. It can be use to build body tissues and bones.
3. To fight pathogens or fight infections.
4. It can be use for bones development.
