This statement is false. This is because the green light isn't absorbed. The leaves appear green because the chlorophyll of the leaves, the part that makes food, reflects the green light, which has a medium wave length. While reflecting green light waves, it simultaneously absorbs red waves (long waves) and blue waves (short waves)
Hope this helps, and hope I was the brainliest!
Multiply 5730 years by 2 since two half-lives have gone by for carbon.
<u>Explanation</u>:
The half-life of a radioactive isotope depicts the measure of time that it takes half of the isotope in an example decay. On account of radiocarbon dating, the half-existence of carbon 14 is 5,730 years
The half-life of carbon-14 is 5730 years.
In this manner, after
1 half-life there is 50 % = 1/2 of the first amount left.
2 half-lives there is 25 % = 1/4 of the first amount left.
25% is two half-lives.
Every 50% of life requires 5730 years.
So two half-lives require 2 × 5730
The correct answer to this question is C. 5.00 x 10^14 (you have two B's marked)
I just turned in the Odyssey-ware assignment with this answer and it was correct
Answer:
The mutation is created at a site defined in the DNA sequence. First, it is necessary to synthesize the primer, which contains the mutation. Said primer needs to hybridize with the DNA molecule that has the gene of interest. Using the enzyme DNA polymerase, the mutation is incorporated and allows the formation of the complete DNA. This DNA chain can be introduced into a host cell and subsequently cloned
Explanation:
With this technique it is possible to establish specific mutations, deletions or insertions. Through this it is possible to control the type of mutation that is wanted in the DNA. For example, in the case of deletions, primers are used which, in addition to having their capacity to perform the deletion, should also be able to hybridize the DNA chain. To carry out an insertion, said primer must have the DNA fragment in addition to being able to hybridize the DNA.
