The algae in the ocean have a very high Net Primary Productivity (NPP) and a very low amount of store biomass. This is because THE GROWTH RATE OF ALGAE IN THE OCEAN IS HIGH. The store biomass is low because THE PRIMARY CONSUMERS FEED ON THESE ALGAE THUS LOWERING THE BIOMASS AMOUNT. The production of biomass is related to the NPP.
Answer:
they produce antibodies that attach to viral surface protiens
The question is incomplete. The complete question is as following:
In humans, the pelvis and the femur, or thighbone, are involved in walking. In whales, the pelvis and femur shown in this figure represent...
Answer:
vestigial structures
Explanation:
A "vestigial structure" or "vestigial organ" are defined as the organs that no longer have any function in the organisms' body but had an important role in past.
<em>Pelvis and femur are thigh bones in humans which helps them in walking but in whale's pelvis and femur are considered as vestigial structures. </em>
The pelvis and femur in whales, are the inherited structure from ancestors and shows evidence for evolution on the basis of natural selection.
Hence, the correct answer is vestigial structures.
Answer:
Ribosomes are present attached to the rough ER:
1. To easily make proteins that are required inside and outside of a cell.
2. To take up amino acids easily.
3. To make it easier for the mRNA to travel from the nucleus to the ribosomes.
Explanation:
Ribosomes are involved in the synthesis of proteins. The rough endoplasmic reticulum is attached to the nuclear envelope. Hence, this provides an easy pathway for molecules to travel between the nucleus, rough ER and endoplasmic reticulum.
During the formation of a protein, mRNA is formed and the mRNA travels to the ribosomes through the rough ER. The location of the ribosomes makes it easy to take mRNA from the nucleus and amino acids from the cytoplasm and make proteins. When a protein is made, it can be used inside the cell or can be transported to the Golgi apparatus etc.
The answer is A area c alone
