Answer:
<h2>Its true!!</h2>
Explanation:
Actually the haemoglobin molecule consists of 2 parts, the haem which is a prosthetic group and the other globin which is a protein. So the haemoglobin as is a protein so, is arranged in quaternary structure of protein which contains 4 subunits. The subunits depend upon the organism whose haemoglobin is being talked about. So the normal haemoglobin found in red blood cells contains 2 alpha subunits + 2 beta subunits. At the centre of each subunit there is the haem part attached. To the centre of haem the Fe3+ ion are present which actually attaches to 1 Oxygen molecule. So as 4 subunits are present and each subunit has 1 Fe3+ ion, so total 4 Oxygen molecules can bind to the 1 Hb molecule!!
Answer:
The possible blood types of their children are: type AB (iAiB), type A (iAi), type B (iBi), type O (ii)
Explanation:
Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but co-dominant. The following blood types are encoded by the following alleles:
Blood type AB - iAiB
Blood type A - iAiA or iAi
Blood type B - iBiB or iBi
Blood type O - ii
According to this question, a man who has type B blood has children with a woman who has type A blood. They are both heterozygous, meaning that the man's genotype is "iBi" while the woman's genotype is "iAi". Both parents will produce gametes as follows:
iBi = iB and i
iAi = iA and I
Using these gametes in a punnet square (see attached image), the following possible blood types are produced in the offsprings:
- type AB (iAiB)
- type A (iAi)
- type B (iBi)
- type O (ii)
Answer:
A. Individuals and families ended up polluting more than factories
Explanation:
Bone remodeling is a process in which bone tissue is replaced by newer bone tissue. It can be used to determine age because we take the bone tissue that was removed from the skeleton and based on its structure we can determine at what age was it removed from the skeleton.
Veins carry deoxygenated blood from the body to the heart so it can be sent to the lungs, pulmonary veins takes oxygenated blood from the lungs to the heart.
