Because we have been to busy trying to explore new areas rather than our own and were probably to scared to know what's in our planet so it doesn't cause panic
Answer:
Bacteria
Explanation:
Bacteria have no true nucleus because it's a prokaryote. It couldn't have been a virus because all naturally occurring viruses are pathogenic unless treated by radiation.
We have two types of bacteria,
- Pathogenic
- Commensals
Pathogenic bacteria will definitely cause disease. Commensals, however, have don't harm us and have the ability to help us.
Eg: Flora (bacteria) in our intestines produce vitamin K and most of the vitamin B complex. They also compete with the pathogenic bacteria that you might've ingested and don't allow them to increase to the number that can cause disease.
If the ATP synthesis in the mitochondria of a plant's cells suddenly operated poorly t<span>he plant cells would die because they wouldn't extract enough energy from the glucose produced in photosynthesis. </span>
Answer:
D-A double layer of phospholipids with proteins
Explanation:
A is describing a cell wall, C is describing cytoplasm, B is describing DNA.
Answer:
A. Destruction of terrestrial biota
Explanation:
all the other answers would decrease the carbon output. thickening of ocean sediments reinforces a carbon reservoir (which stores carbon), reduction in the use of fossil fuels would reduce the amount of carbon emissions, increase in marine biota = increase in carbon storage because marine biota is also a carbon reservoir.
Destruction of terrestrial biota would cause excess output because terrestrial biota is a carbon reservoir, and all of that carbon would be released into the carbon cycle.
