Answer:
If both parents do not have sickle-cell anemia, than the possibility is low.
Explanation:
If both parents have the sickle-cell trait, their offspring has a 25 percent chance of getting sickle cell anemia and a 50 percent risk of them having sickle cell trait. Meanwhile, there is also a 25 percent chance of the child not getting it at all.
If one parent has sickle cell anemia and the other has sickle cell trait, then their offspring with have a 50 percent chance of getting sickle cell anemia and a 50 percent chance of getting a sickle cell trait.
When both parents have sickle cell anemia, their child will definitely have it.
Answer:
No, 0% chance
Explanation:
none of the parents are carriers of this disease, and are homozygous dominant to the normal red blood cells, so they will not inherit this disease
selection not occur in this population?
O
A. There is no diversity in the population,
O
B. The population is above carrying capacity.
O
C. There are enough resources for the birds.
O
D. There is nothing to cause genetic mutations.
The natural selection would not occur in this population because : ( C ) There are enough resources for the birds.
Natural selection is a process whereby populations of organisms living in an environment adapt and change due to selective reproduction of genes in its genotype. Natural selection is triggered by certain environmental factors. In the scenerio protrayed in the question there is an abundance of resources for the birds therefore natural selection will not occur.
Hence we can conclude that there are anough resources for the birds

Answer:
C. There are enough resources for the birds.
Explanation:
Answer:
The answer is: It means it is a membrane that will allow certain molecules or ions to pass through it by means of active or passive transport.
Explanation:
All cells are enclosed with a cell membrane. The term, selectively permeable, refers to :
the membrane allows some substances or molecules to enter the cells, and others to be prevented from entering. It also allows substances to leave the cell.
This process can be done by :
Active transport -requires the cell to expend energy to move the materials.
Passive transport- it can be done without using cellular energy.
