Answer:
The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
Explanation:
The aniridia allele in females has to be in the XAXA or XAXa form to be expressed but in males, can be expressed when genotype is XAY.
Migraine headaches allele in females has to be in the XMXM or XMXm form to be expressed but in males, can be expressed when genotype is XMY.
A man with normal vision and without migraines (XaY/XmY) had a father who had aniridia (XAY).
The man's father genetics for aniridia is XAY because one copy of the altered gene in each cell is sufficient to cause this disorder.
The answer is A. C and G go together and A and T go together.
Answer:
A substance that removes carbon dioxide gas
Explanation:
Options-
A. A substance that removes carbon dioxide gas
B. A plant to produce oxygen
C. A glucose reserve
D. A valve to release excess water
Solution -
It is given that the rate at which oxygen is consumed and the rate at which carbon dioxide is produced is same. Therefore, if we somehow are able to measure the volume of carbon dioxide, we can interpolate the rate of consumption of oxygen from it.
Hence, A substance that removes carbon dioxide gas is essential to provide accurate volumetric measurements of oxygen gas consumption
Option A is correct
