When the nucleus of a U-235 atom captures a moving neutron it splits in two (fissions) and releases some energy in the form of heat, also two or three additional neutrons are thrown off. If enough of these expelled neutrons cause the nuclei of other U-235 atoms to split, releasing further neutrons, a fission 'chain reaction' can be achieved. When this happens over and over again, many millions of times, a very large amount of heat is produced from a relatively small amount of uranium.
It is this process, in effect "burning" uranium, which occurs in a nuclear reactor. The heat is used to make steam to produce electricity.
Answer:
The weight of chickens would be on the x-axis (horizontal) and number of eggs would be on the y-axis (vertical)
Explanation:
The number of eggs a chicken has is dependent on the weight of the chicken
6. mitchondria
7. fermentation (anaerobic = NO oxygen)
8. PRODUCES lactic acid and energy
9. REACTANTS are glucose (to give energy) and water
10. Since energy is being wasted/unused, <span>the amount of usable energy is lower for anaerobic respiration than aerobic respiration</span>
<h2>Mutation will occur </h2>
Explanation:
Base excision repair operates for small DNA damage such as deaminated bases
- DNA glycosylase plays an important role in cleavage of glycosidic bond of abnormal base (does not cleave phosphodiester bond)
- Uracil is incorrectly paired with guanine then mutation will occur
- The original GC base pair will change into AT base pair(transition of GC to AT)
- Transition is a mutation in which one purine(adenine or guanine) is substituted for other or one pyrimidine(cytosine or thymine or uracil) is substituted for other
Well, while it is true that the plant cell wall is rigid it's more important that it stretches. That's how it protects.
