Viruses and bacteria can both be pathogens,
ad-work [718]

Answer:

True

Explanation:

Bacteria generate toxins which can be classified as either exotoxins or endotoxins. Exotoxins are generated and actively secreted; endotoxins remain part of the bacteria. Usually, an endotoxin is part of the bacterial outer membrane, and it is not released until the bacterium is killed by the immune system.Most viral infections eventually result in the death of the host cell. The causes of death include cell lysis, alterations to the cell's surface membrane and various modes of programmed cell death. Some viruses cause no apparent changes to the infected cell.

There are about 11,200,000 billion metric tons of O2 in the atmosphere. Based on an estimated photosynthesis rate of 600 billion
Nadusha1986 [10]

Answer:

t=18666.7years

Explanation:

Hello,

In this case, since the rate at which oxygen is produced via photosynthesis is:

600 \frac{billion\ metric\ tons}{year}

Since the desired amount is 11,200,000 billion metric tons, the required time is:

t=\frac{11,200,000billion\ metric\ tons}{600 \frac{billion\ metric\ tons}{year}} \\\\t=18666.7years

Best regards.
