Explanation:
Answer:
II and III
Explanation:
<em>I. All sons of these parents will be a hemophiliac.
</em>
<em>
II. A son who suffers from hemophilia received the hemophilia allele from his mother.
</em>
<em>
III. Half of the daughters of this cross are predicted to be hemophiliacs.</em>
Assuming the haemophilia allele is represented by h, the alternate form being H.
A woman that is a carrier will have the genotype
.
A man who suffers from haemophilia will have the genotype 
Crossing both of them:
x
= 
From the result of the cross, the following can be deduced:
- Half or 50% of the sons from the couple will be haemophiliacs.
- Any son that suffers from haemophilia received the allele from the mother.
- Half or 50% of the daughters from this cross will be hemophiliacs.
Hence, statements II and III are true.

Essential amino acids are those amino acids which are not synthesized by our body. They are supplied through the food we eat. If a person is not getting the required essential amino acids in the body, it will affect both physical and mental health. In the absence of essential amino acid body breaks down muscle tissue to get the required amino acid, therefore muscle wasting is the first symptom of the deficiency of essential amino acids. Low level of essential amino acid may cause high anxiety.
