The answer is; D
Radioactive waste poses a serious challenge to the environment. Any leakage of the waste is risky because the radioactivity can flow up the food chain and it also takes time for it to decay and become less harmful. Therefore, its effect can be felt over many generations. Therefore, safe storage of radioactive waste is a challenge (and can be very expensive) and a deterrent for pursuing the potent energy source.
Answer: True
Explanation:
In incomplete dominance, neither of the alleles in an heterozygous condition is dominant, thing the organism will show a form of phenotype in which the physical trait expressed is a combination of the two alleles.
The options for this question are:
- Requires genetic variation
- Results in descent with modification
- Involves differential reproductive success
- All of the above
Answer:
<u><em>The correct option is d) All of the above</em></u>
Explanation:
The theory of natural selection explains that genetic variations occur in organisms of a species. Those organisms which are better adapted to live in an environment are able to survive and pass on their characteristics to their offsprings, hence descent with modification. Through this phenomenon, evolution takes place with the passage of time. Natural selection favours survival of the fittest. Hence, all of the above statements are true.
Look up Dawrin's theory of evolution. Basically, fossil records show how life forms change over time through evolution.
It is important that it has half because there is a half that comes from each parent. so to equal it all out human gametes have a half set of dna instead of a full set
