Dafna1 [17]

Answer:

Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.

Both klebsiella pneumoniae and streptococcus pneumoniae avoid phagocytosis by releasing a-b toxins that kill leukocytes.
Kobotan [32]
This is a false statement.

Klebsiella pneumoniae and Streptococcus pneumoniae are two bacteria who are encapsulated, that means that they are surrounded by an envelope. This capsule is critical to their pathogenicity since it protects them from the phagocytes of the human immune system. Certain proteins located on the surface of their capsule prevent the phagocytic cell from adhering to the bacteria and engulfing it.

Their Diversity and number will be greatly diminished.

Diversity:

  • Increase in atmospheric $\mathrm{CO}_{2}$ is a direct consequence of human activities such as deforestation, over population, Factories, vehicles.
  • The direct consequence of increase $\mathrm{CO}_{2}$ Level in waster is the acidification of water because $\mathrm{CO}_{2}$  water and carbon dioxide together produce carbonic acid.  \mathrm{CO}_{2}+\mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{H}_{2} \mathrm{CO}_{3}
  • Our worldview, viewpoint, and method are all shaped by a confluence of our differences[1]. Diversity also refers to the acceptance, value, and recognition of differences based on sexual orientation, gender, age, race, religion, and ethnicity.
  • Every culture, every nation, and every single person has a unique perspective on the world. Every culture, nation, and person has their own own knowledge, opinions, and points of view. Miracles can occur when these many points of view are combined.

Slav-nsk [51]

Toxins are microbial proteins with a strong specificity for a target cell that exert extremely powerful and toxic effects on that cell.

<h3>What are toxins?</h3>

Toxins are molecules that are produced by certain organisms which are deadly to other organisms when these organisms come in contact with them.

Toxins are produces mostly by microorganisms as well as some plants and animals such as fishes.

Toxins are mostly proteins products are usually specific for their targets cells.

Therefore, microbial proteins with a strong specificity for a target cell that exert extremely powerful, and sometimes deadly, effects on that cell are called toxins.
