The best way may be is going over the notes on the chapter you were doing. Or going over the chapter once or twice.
Answer:
given, mother and father are heterozygotes.
let, father has B blood group and mother has A blood group.
then their heterozygous genotypes are --
father = iB, iO and mother = iA, iO
punnett square will be,
iB iO
iA iA iB iA iO
iO iB iO iO iO
the genotypes of their progeny will be, iAiB , iAiO ,iBiO and iOiO
and phenotypes will be 3 are heterozygous and 1 is homozygous.
As when things get eaten some of the energy is lost the predators have to have more than one prey to survive, this means there is only a limited amount to be shared which means less predators
Answer:
The correct answer will be option a and b.
Explanation:
The food is digested and absorbed in the small intestine, a long folded tube which lengths about 20 ft or 6m.
The small intestine increases the surface area for food absorption as they have circular folding as well as the finger-like projections called villi and microvilli in the lumen of the intestine. These villi help in absorption of the nutrients from the intestine.
Thus, option a and b are the correct options.
When red blood cells are in a higher concentrated solution, water flows out of the cells faster than it comes in. This results in crenation or shrivelling of the cell.
