Answer:
a. individuals with type AB blood can only receive a transfusion of type AB blood
Explanation:
Type AB blood can receive transfusion from all the other blood types<em> (A, B, AB and O).</em> This is why, it is considered to be the <em>universal recipient.</em> Thus, <u>this makes choice a false</u>.
On the contrary, the universal donor among the blood types is <em>type O blood</em>. This means that a person with this type of blood can donate to all types of blood because it is compatible. However,<u> it can only receive transfusion from the same blood type O.</u>
The type of cellular transport that does not involve the flow of particles from an area of high concentration to an area of low concentration is called the active transport.
Cellular transport of ions, gases, nutrients, waste substances and other biomolecules is of two types namely, the passive transport and the active transport. Passive transport is the movement of substances along their concentration gradient from a region of their higher concentration to the region of their lower concentration which does not require energy.
Active transport is the movement of substances against their concentration gradient from a region of their lower concentration to the region of their higher concentration. It uses energy in the form of Adenosine triphosphate (ATP). The best examples being the sodium-potassium pump in the cells and the uptake of glucose in the intestines.
Answer:
According to the genetic code, the amino acids are the following:
- Glycine: encoded by GGC, GGA and GGG codons
-Arginine: encoded by AGA and AGG codons
-Lysine: encoded by AAA and AAG codons
-Glutamic acid: encoded by GAA and GAG codons
Explanation:
The probabilities to observe an amino-acid formed by Glutamic acid in the coding sequence is 2/9 for each codon
