Answer:
Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.
Explanation:
<span>The common misconceptions she thinks are that people believe that pesticides are used for agricultural purposes whereas many times pesticides is also used in houses or gardens round houses so direct contact with pesticide is quiet common. Another misconception is that low level of pesticides is not dangerous whereas studies have shown that prolonged, low-level pesticide exposure can also cause peripheral neurotoxicity.</span>
Answer:
The parents must be Tt, Tt
Explanation:
Based on these results, we can conclude that each of the parents will have one dominant (T) and one recessive allele (t). We can prove this by drawing the Punnett square:
T t
T TT Tt
t Tt tt
We can see that the offspring will have the Tt genotype in two cases, the TT genotype in one case, and the tt genotype in one case, as well. Now we need to do some basic math. Two out of four is 50% (Tt - 50%), and one out of four is 25% (TT - 25%, tt - 25%).
This means that the parents must be Tt, Tt.
Answer: B) seeding
Explanation:
The seeding is a process of addition of microorganisms to the oil spill so that the microorganisms eat up the components of the oil or degrade or convert the oil into a form which helps in reducing the pollution caused by the oil spills. This is an ideal approach to clean up the oil spills from the water body. The microbes will colonize in short period of time and will degrade the oil spill efficiently.
The given situation is indicating towards the seeding of the non-indigenous microbes for degrading the oil.
Because when the DNA replication occurs, it will first uncoiling. And each strand will be a template for replicating. So the new DNA will have one strand from the origin DNA and one strand from newly synthesis. That's the reason of semi-conservation.
