Answer: A gyrus (plural = gyri) is the ridge of one of those wrinkles, and a sulcus (plural = sulci) is the groove between two gyri. The pattern of these folds of tissue indicates specific regions of the cerebral cortex. The head is limited by the size of the birth canal, and the brain must fit inside the cranial cavity of the skull.
Explanation: Hope this helps :)
Oxygen, water, some type of resources to build, and food to eat
The answer would be D.nucleus, prokaryotic cells don’t have a nucleus instead their dna floats around inside the cell
Let a be Q, all which is homozygous recessive = Q∧2
A = p, AA which is homozygous recessive = Q∧2
2pq = heterozygous
It is derived from p+ q = 1
All those in a population which is Q = 20%
All A in the population (p) = 80%
Now that the disease is homozygous recessive therefore,
aa = qq or q × q = 0.20 × 2 = 4%
Then the answer is 4%.
