The correct answer is option B) their DNA sequences.
The best comparison for finding out the evolutionary relationship between two organism is the comparison of their DNA (deoxyribonucleic acid) sequence. The organisms, which are more closely related to one another share more similarity in the DNA sequence as compared to the distantly related organism, so, the comparison of the DNA can help in determining the evolutionary relationship between the organism.
Answer:
4.Cell wall protects the cell whiles organelles are found in the cell itself which is having the cell wall
A DNA temp is used to make a RNA strand !!
so your answer is C !!
Answer:
True.
Explanation:
Large proteins are regarded as large size molecules , or macro-molecules. And they are known to made up or contain polymers of structural units, which are known as amino acids.
In summary, large proteins are generally known to consist of several distinct protein domains, i.e structural units that fold more or less independently of each other.
Therefore , in this case, the large protein will remain in the capillary, and eventually result to the development of an osmotic pressure difference across capillary walls.
Answer: Over 4 billion years ago
Explanation: The chemical reactions between carbon and water is said to bring about life according to scientists. These reactions builds largely upon four families of chemicals (lipids, carbohydrates, amino acids, and nucleic acids).
However, the actual time of life on Earth has varying speculations from different scientists in fields of study (such as molecular biology, chemistry, oceanography, etc).
Furthermore, microfossils within hydrothermal-vent precipitates dated from 3.77 to 4.28 billion years is presumed to inhabit the oldest record of life on Earth. Hence, which is presumed to have occurred after ocean formation 4.4billion years ago.
Thus, the actual date of the chemical reactions that brought about life is not rigid, but presumed to have occurred over 4billion years ago (according to research).
