Answer:
C carbon monoxide
Explanation:
it combines with haemoglobin more faster than CO2 and O2 hence reduces O2 level in blood
Answer:
1. Weaker
2. Continuous
Explanation:
A tumor suppressor gene codes for retinoblastoma protein (pRb). The retinoblastoma protein binds to transcription factor E2F when DNA damage is detected. The E2F bound to pRb can not stimulate expression of genes that code for proteins required during the process of DNA synthesis. The cell can not enter the S phase.
On the other hand, when the retinoblastoma protein is phosphorylated by cyclin E-CDK2, E2F transcription factor is free to stimulate the expression of genes required for DNA synthesis and the cell proceeds from G1 to S phase.
When the mutated retinoblastoma gene code for a protein that serves as phosphorylated protein, it will not be able to bind strongly with E2F and there would be continuous expression of genes required for S phase.
Body cells are those that are responsible for the formation of tissues and organs, while a gamete is that cell responsible for reproduction.
- Gametes are sex cells, when a male gamete joins a female gamete in the framework of sexual reproduction of plants and animals, a zygote is formed.
- Body cells are any cell in the body that are not gametes, which originate from embryonic stem cells and constitute the totality of the body's tissues and organs of multicellular organisms.
Therefore, we can conclude that body cells are those cells responsible for the growth of organs and tissues and gametes are each of the sex cells that fuse during fertilization.

In a food chain, plants are primary producers, as they produce biomass.
