Bogdan [553]3 years ago

Answer:

Every human has a couple of genes that will be separated when they make gametes. A baby will get one gene from each parent (one sperm and one egg).  

Sickle cell gene is inherited by an autosomal recessive pattern, which means you need both defect genes to get the disease. The person with 1 defect gene can survive and live like normal. This person called a carrier because they carry one defect gene.

Someone that carries one defect gene can come as a result if you cross normal or carrier genotype (AA/Aa) with a carrier(Aa), or with homozygote recessive that carries 2 defect genes (aa). The person will get one healthy gene from the first parent with normal genes, and one defect gene from the second parent.

Answer:

Senior mothers are also under pressure to share food with their sons, so that they're able to reproduce as well. It also makes sense for these mothers to assist their sons because as the mothers grow older, they are increasingly related to whales in other, neighboring pods via their sons' calves.

Ceruminous glands are ________. Ceruminous glands are ________. saliva glands found at the base of the tongue modified taste bud
kogti [31]

Answer:

Modified apocrine sweat glands

Explanation:

The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.

As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.

This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.
