Answer:the second blank is respiratory
Explanation:
Biome
a complex biotic community characterized by distinctive plant and animal species and maintained under climatic conditions of the region, especially such as a community that has developed to climax.
Answer:
The correct answer is -
Thymine: 20%
Guanine: 30%
Cytosine: 30%
Explanation:
According to Chargaff's rule which states that the purine residues are equal to the pyrimidines residue in DNA sample which means A+G = T+C where A is adenine, G is guanine, C is cytosine and T is thymine. It is also known that A is always equal to T and C is equal to G.
So, A+G+T+C = 100
20+20+G+C
100-40 = G+C
60= G+C
as we know G is equal to C similarly A is equal to T
Thus, G = C= 30%
A= T= 20%
Answer:
It was thought that plants evolved from stonewort-like algae. New research shows that the closest relatives to land plants are conjugating green algae
If you are talking about evolution, the two types of evidence is
1. fossil evidence
2. molecular evidence
