Answer:
The options are
a.cooling of the power plant
b.mining of uranium
c.storage of radioactive waste
d.monitoring the reactor
The answer is b.mining of uranium
Explanation:
Uranium is known as a radioactive element which is used as a fuel to power a nuclear energy plant. Mining of uranium could cause it to mix with air and water which results in contamination.
When contamination occurs and it gets into the body of humans or animals by inhalation or ingestion it poses a high risk of cancer and kidney damage.
Answer:
Electron transport chain is the last step of respiration.
Explanation:
Respiration is a cellular process in which glucose molecule is broken down into carbon dioxide, water and ATP is produced as end product. Respiration consists of following main steps:
1. Glycolysis:
It occurs in the cytoplasm of cell, and each glucose molecule is converted into two pyruvates with help of ATP.
2. Formation of Acetyl coenzyme A:
It is a connecting link reaction between glycolysis and Kreb cycle. In this phase Each pyruvate react with Coenzyme A to become acetyl coenzyme A.
3. Kreb Cycle:
It occurs inside mitochondria. In this cycle each acetyl coenzyme A with fixed with CO to produce citrate which undergo in a cyclic reaction to produce ATP and NADH. .
4. Electron transport chain:
It is the last step of respiration which complete in mitochondrial membrane. In this phase most of the energy is produced along with H₂O as by product.
Conclusion:
It was concluded from the above discussion that the last process that takes place in respiration is electron transport chain.
B, a nucleus. Nuclei are membrane-bound organelles inside eukaryotic organisms. Eukaryotes are protists, fungi, plants, and animal cells. A bacteria is not a eukaryote, it is a prokaryote, so it does not have the membrane-bound structure of the nucleus.
Be careful, though, bacteria still have DNA. It is simply located in the center of the cell and is not encased in a membrane.
Cancer cells and Corona virus
If it is the fill in the blanks.The answer is The circles,or orbits,for electrons are called energy levels.
