Answer:
18 is the nuclesus, 20 is the smooth endoplasmic reticulum and 21 is the golgi apparatus and 19 is the microtubes and 17 is the vacules.
Explanation:
. DNA replication is a highly accurate process, but mistakes can occasionally occur as when a DNA polymerase inserts a wrong base. Uncorrected mistakes may sometimes lead to serious consequences, such as cancer. ... Mutations: In this interactive, you can “edit” a DNA strand and cause a mutation.
Answer:
Explanation:
A. There is a greater risk of E.coli infection from hamburger consumption than in steak. Hamburger is made with ground beef and bacteria which includes E.coli spreads more in ground beef. On the contrary, steak is not ground meat so the spread of bacteria in it is reduced compared to hamburger.
B. Food poisoning can still occur. Though staphylococcus aureus can easily be killed by the heat associated with warming, it's toxins which are responsible for food poisoning are heat resistant and can still cause diseases even after reheating of food.
Given that a blowfly starts its lifecycle only if there are appropriate conditions met, one of which is suitable temperature, the correct answers as to what can impact the timing of the blowfly lifecycle is the air temperature.
I don't see how humans will impact when this fly is going to be born, so A and C are incorrect. Leaves also doesn't really affect blowflies, which is why D is incorrect as well.
Answer: 2 - The nucleus of an atom is split apart
Explanation: Any reaction involving the nucleus of an atom is called a nuclear reaction. It is different from ordinary chemical reactions that involve electrons because it involves the release of large amount of energy. Nuclear reactions can be classified as nuclear fission and nuclear fusion.
A nuclear reaction in which a nucleus of an atom is split into two smaller atoms with a release of large amount of energy is called nuclear fission. A nuclear reaction that involves the combination of lighter nuclei of elements to form heavier atoms that are more stable with the release of a large quantity of energy is called nuclear fusion.
