the answer is actually A. chemical weathering by oxidation .
chemical weathering works on rocks that contain iron. These rocks turn to rust in a process called oxidation. Rust is a compound created by the interaction of oxygen and iron in the presence of water.
I think it's A not sure tho
Answer:
The enveloped viruses are resistant to disinfectants.
Explanation:
The outer covering or the envelope in the virus comes from the infected cell. This envelope is formed by the process called as budding off, from the host cell. The envelope that covers the virus provides resistance to various disinfectants and prevent virus from damage. The outer coat (envelope) is formed of a small part of cell membrane.
The virus that lyses and kills the cell immediately is less worse than the enveloped virus. The virus that kills cells immediately prevents the host cell from continuously synthesizing new virus particles. Thus, no more viral particles can be produced by the host cell. So, envelope viruses are worse that viruses that directly kills the host cell.
Plant produces glucose in the chloroplast through the process of photosynthesis. Calvin cycle is basically the biological process through which glucose is produced. The steps involved are as follows:
1. Absorbed CO2 is added to RuBP and 6C sugar is formed.
2. Breaking of 6C sugar into two 3-phosphoglycerate molecules
3. ATP gives phosphate group to form 3-phosphoglycerate which is later on converted into 1,3-biphosphoglycerate.
4. Electons are required by 1,3-biphosphoglycerate to an aldehyde called glyceraldehyde-3-phosphate or G3P and these electrons are donated by NADPH
5. Enzyme aldolase uses two molecules of G3P to produce 6 C sugar called fructose-1,6-biphosphate which is further converted to fructose-6-phosphate
6. Enzyme isomerase converts fructose-6-phosphate to glucose-1-phosphate
