We know, DNA is the main molecule by which scientists can learn about evolution by comparing the DNA structure between two different organisms.
But, in addition to DNA (which is most helpful & important) still, there are 3 molecules that can help us, They are:
1) RNA : - It is found in cytoplasm, as DNA transfers it's codes into RNA during Central dogma, it can help us in evolution studies.
2) Proteins: - Another helpful feature, into which RNA transforms in Central Dogma.
3) Pseudogenes: - It is also known as "Non-coding DNA" It is extra <span>DNA in a genome that do not get transcribed into RNA to synthesize proteins. They can also help us in Evolutionary studies.
Hope this helps!</span>
Answer:
Stream volume and speed directly affects the size, shape, and flow of streams and rivers.
Explanation:
- The greater volume results in larger channels and these larger channels will make the flow of stream faster.
- The flow volume of different streams are related to precipitation and run-off.
- The earth materials also heavily effect the flow by changing the properties of the water like increase in the mass, hardness, shape, etc.
- Erosion and deposition is common in the curving type of stream.
Answer:
Population is a collection of individuals of a species living in a defined area
Explanation:
Population:This is a collection of individuals of the same species occupying the same space and able to interbreed freely with one another when individuals of different sexes are brought together.
A species of animals may comprise a single cohesive population or may contain many geographical distinct populations.
Example:A population of Agama lizards in a Campus located in China.The whole human race, Homo sapiens comprising the black, Mongolian,red and white is a population.A population of <u>Cercopithe</u><u>c</u><u>us</u> <u>erythrogaster</u><u> </u>(Monkeys).
