One example can be the needle shaped leaves.
In desert areas, there are not much water sources. So basically, any drop of water is precious. To help prevent water loss of plants, for example cactus has very thin leaves that are needle shaped. Or some even don't have any leaves. This can reduce the surface area of leaves and thus reduce the water evaporating to the outer environment.
Another example also shown on cactus is that they have very thick waxy cuticle. It can also prevent water from evaporating from the stem. So that's why you see the stem is very shinny.
In a tropical rain forest, the layer formed by the leafy tops of tall trees is called the Canopy and the layer of shorter trees and vine is called the Geographic range.
Answer:
The bacterial fission occurs by the following method:
The DNA replicates. The replicated DNA is copied and it moves to the opposite sides of the cell. The length of the parent cell increases. The cell divides from the center with distribution of equal amount of DNA. After this, the cell wall is formed.
In protist fission: In protist fission, the nucleus of the parent cell divides many times. After this cytoplasm separates and forms around the daughter nuclei.
False
A star is a large celestial body, but it is composed of very hot hydrogen gas.
I feel like you're neglecting to add something, but here are the 22 amino acids:
Alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine, selenocysteine, pyrrolysine
The eight main ones that are essential for us are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine
