Both parents are normal. But, some of the kids have the disease. This indicates that the parents are heterozygous for the disease (let's use Dd). They are phenotypically fine because D is normal. But we know they must both carry the diseased d allele because their kids have the disease.
If you cross Dd x Dd you get DD, Dd, Dd and dd as the possible outcomes. But because each time they have a child they roll the dice as to which of the 4 above happens, they were unlucky as 3 of those times they got dd for their child...so 3 of them have the disease (and are dd). One is phenotypically normal but could still be Dd or DD.
Glucagon and Insulin are both hormones that regulate blood sugar levels and they are both produced by the pancreas.
When sugar levels in the blood are high the pancreas secretes insulin from its beta cells and releases it into the blood stream. Insulin causes the red blood cells, fat cells and muscle cells to absorb sugar from the blood .
When sugar levels are low, the pancreas secrets glucagon from its alpha cells which stimulates the liver to release the glucose that is stored in its cells.
Thus these two hormones work in the body to keep sugar levels balanced.
Answer:
well they can be both sometimes, some can survive in very hot environments, but most can be killed by heat so it is prokaryotic
Explanation:
From what I believe, 50%. The chromosome from the father can either be X or Y, so it’s a chance to carry it in the X gene if the child is a girl. If its a boy, then it has no chance of carrying the gene. Hope this helps
Answer:
A
Explanation:
If a woman with type AB blood and a man with type A blood have a child, the genotype will be AA and and AB (that is, a combination of the mother and father's gene).
Phenotype refer to the gene that is actually expressed. In this case, A.
In the example above, there are 2 phenotypes of Type A blood. The type A blood phenotype can result from two genotypes of AA and AB.
