Answer: The answer is option B. Cell Walls
Explanation: Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. In eukaryotes, vertebrates don't have a cell wall but plants do.
Albinism is a recessive trait characterized by an absence of pigment melanin responsible for skin and hair color. Actually, albinism is caused by a defect in gene for enzyme which synthesizes melanin. The central dogma of molecular biology explains that the sequence of DNA specifies the sequence of mRNA, which, further, specifies codes for the sequence of proteins. Since a gene is a segment of DNA, altered gene will cause altered mRNA which will cause altered protein. Thus, <span>defect in gene for enzyme which synthesizes melanin will cause the absence of melanin and consequently, albinism.</span>
The correct option is this: THERE IS MORE BIODIVERSITY IN THE SUBLITTORIAL ZONE COMPARE TO THE UPPER INTERTIDAL ZONE BECAUSE THERE IS LESS TEMPERATURE VARIATION IN THIS REGION.
The sublittorial zone refers to the part of the ocean that is about 200 meters away from the surface. The zone is characterized by constant temperature as a result of the constant sunlight that reaches the depth; this leads to more biodiversity in this zone.
