Answer:
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.
Explanation:
A cell wall is a rigid, semi-permeable protective layer in some cell types. This outer covering is positioned next to the cell membrane (plasma membrane) in most plant cells, fungi, bacteria, algae, and some archaea.
Answer:
I believe they are called a population, tell me if I'm wrong.
This is because of the populations.
Less water would make a large population dehydrate.
The savanna is very dry and desert like. Grasslands get precipitation and have tons of grass, hence the name grasslands.
Answer:
D) elastic cartilage
Explanation:
Cartilage is a connective tissue which is fibrous in composition which provides its physical properties like the softness, elasticity and strength.
There are three types of cartilages- the elastic, hyaline and the fibrocartilage. Among these three the cartilage which forms the external ear is the elastic cartilage. The elastic cartilage is composed of the elastin protein, type II collagen and the elastic fibres. The presence of the elastin proteins and fibres allows the ear to be an elastic organ.
Thus, Option-D is the correct answer.
