Answer: Leaves have different shape and different function based on the biome in which they live.
Explanation: Different biome have different trees and the structure of leaves are different.
The tundra biome have leaves designed in such as way that it does not allows the snow to stay on the leaves for a longer duration of time.
The desert biome have leaves designed in such a way that it does not allows water loss.
The rainforest biome has leaves designed in such a way that it does not retains water on the leaves for a longer time.
Hey there!
The answer is hydrogen.
Hydrogen is the most abundant element in the <em>universe</em> and is part of the atomic makeup of most celestial objects and even ones on Earth.
Hope this helps!
Answer:
<h2>
Through production of news cell-surface proteins with a different molecular structure by each new generation. Letter B</h2>
Explanation:
The life cycle of theses paratises extracellular alternate between the salivary glands of the insect transmitter and the blood of the mammal. During the set prior to the entry into the host, the metacylic parasites express a dense over formed by the Variant Surface of Glycoprotein, after entering to the mammal host they transform into a morphology that stays in the bloodstream.
<em>The parasites have to manipulate hosts cells in order to avoid the production of antimicrobial molecules and to benefit from growth factor production.</em>
<em>Intracellular protozoa have a remarkable adaptive capacity as they are able to resist killing by remodelling the phagosomal compartments where they reside and by interfering with the signalling pathway that leads to cellular activation. </em>
Factors that affect natural selection include variability among all, reproduction and heredity.because the genetic variability of these species may express genes that are not conducive to the evolution of the species
<h3>What factors affect natural selection?</h3>
For natural selection to occur, there are some factors:
- variability among all
- reproduction
- and heredity.
Variability between substances: Organisms of the same species have variations in their characteristics.
With this information, we can conclude that factors that affect natural selection include variability among all, reproduction and heredity.

Answer: Hydrogen bonds are created between the base pairs in DNA. Adenine pairs with thymine and cytosine pairs with guanine. Adenine and thymine create 2 hydrogen bonds while cytosine and guanine create 3. These bonds are fairly weak so that they can be broken when DNA is replicated (by an enzyme called helicase which unwinds DNA). However despite them being weak they do stabilize DNA's double helix structure as well.
