TRNA reads codons from mRNA and then brings attached amino acids accordingly. Amino acids are connected in long chains called proteins.
Answer:
The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.
Explanation:
In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied. This means making minimal adjustments in order to better observe the microscopic image.
After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.
The other options are not correct because:
<em> A. </em><em><u>Eyepiece</u></em><em> is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.</em>
<em> C. </em><em><u>Coarse Adjustment </u></em><em>is the rough magnification, used for the initial approximation of the image.</em>
<em> D. </em><em><u>Objective lens</u></em><em> enlarges and defines the image of the sample on the slide.</em>
Homeostasis is the maintenance of a relatively constant internal state. It is the process by which living organisms maintain a state of equilibrium in their internal environment. The organs that take part in homeostasis include: the skin, kidney and liver. These organs works together to maintain a stable internal environment.
Answer:
First case:
C -> 30% and T -> 20%
Second case:
C -> 15% and T -> 35%
Explanation:
First of all you should know that if it is DNA, it's formed by two strands. Also, in DNA, the amount of A is the same as the amount of T. And the amount of C is the same amount of G.
So, if you have 20% of A, you will also have 20% of T.
And if you have 30% of G you will have 30% of C
I hope it's useful and that you understand it!
