Heat must be added to make a reduction reaction.
Answer:
Photosynthesis removes CO2 from the atmosphere and replaces it with oxygen.
Explanation:
Photosynthesis removes CO2 from the atmosphere and replaces it with oxygen. By respiration, O2 is removed from the atmosphere and replaced with CO2. However, these processes are not balanced. Some organic matter is not oxidized. (I'm very sorry if I'm wrong but I believe it's that)
D because it makes more sense
i think the answer is B, i may be wrong... because potential energy is stored energy and kinetic energy is energy due to motion so the less potential energy the more kinetic energy
and mechanical energy means the energy of motion, such as a moving vechile which is using kinetic energy.
Answer:
Mutation is the alteration in the DNA base sequence in an organism.it may be due to chemical or environmental effect on the somatic cells..
Generally ,most cancers are caused by mutation in DNA components of abnormal cells.
Basically proto-oncogene is responsible for cell growth and cell division before mitosis in normal healthy cells;thus its codes for the main protein specific for cellular functions in normal cells. Therefore for mutation to occur mutations in mutiple genes is important. .
Basically 2 p53 alleles must be mutated,
2 BRCA1 allele must be mutated,
and 1 mutated allele of HER2 mus be mutated.
All these multiple mutations in these genes are needed.
