Answer:
option 3
Explanation:
In non-homologous end joining, the break ends are directly ligated together without the need for a homologous template unlike the homologous repair. this form of repair uses short homologous sequences of DNA termed microhomologies to direct repair and these microhomologies are seen as single-stranded overhangs found on the ends of double-strand breaks. When the overhangs are perfectly compatible, NHEJ ligates and repair the break. When these overhangs are not compatible, imprecise repair leading to deletion of nucleotides can also occur which is much more common .
Answer:
1.A tissue is a collection of similar cells that work together to perform a specific job.
An organ is a collection of different tissues that work together to perform a specific job. The function of a part of an organism is what it actually does (it's job)
2.The structure of the alveoli as a web of blood vessels surrounding an air sac allows blood cells take in oxygen and bring it into the lungs (organ)
I would say DNA needs to be in a double helix so it can be unraveled and duplicated during cell mitosis
The processes that describes the effect Earth’s atmosphere has on Earth’s biosphere is Ocean levels rise from glaciers melting
Answer: Option B
<u>Explanation:</u>
The earth’s biosphere is a region where the life on earth occurs; the atmosphere is a region of the earth that is made up of gases in the universe. The earth was designed in such a way that the gases in the atmosphere are balanced but due to improper human activities, the percentage of the gases in the atmosphere has become unbalanced, this causes global warming.
