It is both biotic and abiotic
Explanation:
C. Eubacteria and Archaebacteria
Answer:
Option C
Explanation:
Long term hunting has led to following
a) Reduction in population size and hence the gene pool
b) Causation of Bottleneck effect
Due to above factors, the remaining population of Northern elephant seals does not represent the original genetic problem.
Due to this restriction in mating and genetic variation shall prevail pertaining to reduced gene pool.
Due to continuous hunting, the gene pool will further shrink, leading to genetic similarity among the organism
Option C is correct
Why dies???? what do you mean
Answer:
Due to different pigments.
Explanation:
The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.
