Mitochondrion, It's the power house of the cell.
<span>Extraction of DNA is important because of many reasons. With the ability to remove DNA from an organism, scientists can observe, manipulate, and classify the DNA.
Scientists can identify genetic disorders or diseases from studying DNA.
Scientists can possibly find cures for these causes by manipulating or experimenting with this DNA.
Scientists can accurately sort organisms into classes because of DNA uniqueness. If we didn't have DNA extraction, it would be a lot harder to decide which organisms are different from each other.
Scientists can genetically engineer some organisms to produce beneficial things. A common example is that of insulin. Scientists can genetically engineer insulin production so that people with diabetes can live longer.</span>
The answer is seasonal changes.
<span>Animals that live in taiga biomes had to adapt to seasonal changes, by changing
their fur or feather color. For example, snowshoe rabbit and arctic fox live in
taiga and their fur color changes with environmental conditions.
To effectively camouflage, their fur is white during the winter. That
helps them blend into the snow. In the summer, where there is no snow, their
fur is brown and similar to the soil color. This way they evade predators because it is more
difficult for their predators to spot them.</span>
Answer:
( please like and hope it helps)
A) Elephas-2 has 13 sequence differences from the reference animal, and this is the greatest number of animals in the table.
B) From left to right, the order at the tips of the cladogram is: Dugong , Elephas , Loxodonta , Mammathus.
(Loxodonta and Mammuthus can also be reversed)
C) The molecular data, such as that for are widely conserved protein such as cytochrome b , show conserved similarities between organisms such as to dugongs and proboscideans and can be used to support the existence of this relationship.
D) The animals that are related ones had a common assister with certain genetic characteristics. Adaptation to different habitats leads to diversification of morphology but does not change evolutionary relationships.
Answer:
Water is important in chemical weathering because most substances dissolve in water.
The process of dissolving breaks up the minerals in the rock into small pieces. The small pieces mix with water to form.
Acids are also agents of chemical weathering and cause more chemical weathering than pure water does.
