Answer:
B
Explanation:
As there are lots of mitochondria within the diagram it is very unlikely that diffusion occurs. only active transport occurs. cells within the root do not look like the diagram shown thus the statement I and IV are true.
Answer:
See the explanation below
Explanation:
- Transcription/RNA processing: mRNA
- Translation: tRNA, rRNA
- During replication, a faithful copy of a DNA molecule is made.
- During transcription, the DNA "message" is copied onto a molecule of mRNA.
- During translation, the information carried in the mRNA is transferred to molecules of tRNA to build a protein on the ribosomes.
The best answer is C.
When an individual suffers a bacterial infection in the legs, immune proteins called acute phase proteins bind to the surface of the bacteria by a process called opsonisation.
Opsonised bacteria are therefore coated with molecules (self antigens) that phagocytic cells recognize. Activated phagocytes engulf and destroy opsonized bacteria by "swallowing " (engulfing) them.
Inside the phagocyte, enzymes break down the bacteria onto small fragments just the way food is broken down by enzymes in the digestive system. Phagocytes then present the fragments on their surface which helps in the final destruction of the bacteria within the phagocyte.
