Answer:
Some of these proteins serve to transport materials into or out of the cell. Carbohydrates are attached to some of the proteins and lipids on the outward-facing surface of the membrane. These form complexes that function to identify the cell to other cells.
Answer:
The most well-known Hershey-Chase experiment was the final experiment, also called the Waring Blender experiment, through which Hershey and Chase showed that phages only injected their DNA into host bacteria, and that the DNA served as the replicating genetic element of phages

Answer:
Explanation:
A cell is adapted to its function because of differential expression of genes during fetal development during which they get differentiated and determined to provide division of labour to different tissues. They contain protein fibres that can contract when energy is available, making the cells shorter.
Most density independent limiting factors are abiotic (nonliving). So, examples could be temperature, flood, pollution, earthquakes, etc. In your case, the answer would be C. The eruption of a volcano.
Answer A is wrong because that is a description of competition between organisms, which is a biotic factor.
Answer B is wrong because those are both biotic and density dependent factors.
Answer D is wrong because disease is potentially biotic, but primarily because parasitism is mentioned, which is interaction between two organisms. One benefitting, and one being "hurt" in some way.
