The correct answer to this is:
“Astrocytes”
Astrocytes also called star cells due to their shape are the
most abundant glial cells in the brain. Extensions from these cells encase
capillaries and offer extra control over which materials enter or leave the
intercellular fluid of the CNS thus acting like a permeability membrane.
The correct answer for the two missing words are ribosomes and Golgi apparatus. Glands in your neck contain digestive enzymes that help digest starch. Cells that produce and package digestive enzymes must contain relatively large amount of RIBOSOMES and GOLGI APPARATUS in comparison to other cells.
Affirmative, that is correct.
A genetic disorder is nothing more than an abnormal occurrence in a genome, which means that if you change DNA you'll change the genome, and if the change isn't acceptable, genetic disorders can occur easily.
Genetic disorders is a fun field within genetics, and it isn't easy. The functioning of a gene might be an easy concept now a days, but we haven't mastered it. For example, it's not like maths:
- Somebody comes up with a new, unsolved problem, and tries to solve it, and while doing that, the person can create laws, theorems, equations, etc.
Once you come up against a genetic disorder (you can't just create a genetic disorder to study it) you have to study the genetic disorder itself, what caused it and why.
