Answer:
In the case of these two parents, a quarter of their children would have blue eyes.
Explanation:
It is not only possible, it is expected that this would happen an appreciable fraction of the time. Brown eyes are dominant. Suppose eye color were dependent on a single Mendelian gene with two alleles, Br for Brown eyes and Bl for Blue eyes. (As Tracey Bryan has explained, this is not true -- I want to explain what the answer would be even in the simple case.) This means the three possible combinations of two alleles give the following eye colors:
BrBr => Brown
BrBl => Brown
BlBl => Blue
Now suppose two brown-eyed people have a child. We can't tell from the fact that they have brown eyes which pairs of alleles they have. Each of them could have either BrBr or BrBl. Suppose they each have BrBl. When they are crossed (i.e., they have a child), the child gets one allele from its mother -- it has a 50-50 chance of getting either one -- and one allele from its father -- again it has a 50-50 chance of getting either one. So, the child has:
25% chance of getting Br from mother and Br from father => brown eyes;
25% chance of getting Br from mother and Bl from father => brown eyes;
25% chance of getting Bl from mother and Br from father => brown eyes;
25% chance of getting Bl from mother and Bl from father => blue eyes.
So in the case of these two parents, a quarter of their children would have blue eyes.
Answer:
in contrast to normal cells,cancer cells don't stop growing and dividing, this uncontrolled cell growth results in the formation of a tumor /(cancer)
<u>Answer:</u>
Better spreading of reproductive cell is not a benefit of bioflims for bacteria.
Option: (d)
<u>Explanation:</u>
- Bioflims can allow for adhesion of colonies, that can attach surface such as rock, tooth and it includes single or group of micro organism.
- Bioflim bacteria can share 'nutrients' and it is sheltered from 'harmful factors' in environment like desiccation, antibiotics, etc.
- It allow resistance for sanitation, that hold bacteria together and also exclude most disinfectant and antibiotics. It is resistant to sterilization.
Answer:
A very high specific gravity means very concentrated urine, which may be caused by not drinking enough fluid, loss of too much fluid (excessive vomiting, sweating, or diarrhea), or substances (such as sugar or protein) in the urine.
