Answer: Codon

Explanation: A codon is a triplet of nucleotides in an mRNA that codes for specific amino acids. There are 64 possible codons. They are called the genetic codes. Three of these codons (UAA, UAG, UGA) do not code any known amino acid and are thus called termination codons. One of the codons (AUG) signals the beginning of translation and is thus called initiation codon.

The textbook the quantum efficiency for photosynthesis decreases abruptly when the wavelength of light being used becomes longer
Elis [28]

Answer:

The correct answer will be option- A

Explanation:

Red drop effect is the effect observed by the light present in the spectrum of the wavelength of red light. The effect is observed with the decrease in the quantum yield of the oxygen formed per quantum of light when the wavelength of light exceeds 680 nm.

The decrease of quantum yield is observed due to the fact that the oxygen is formed by the breakdown of the water molecule during light-dependent reaction which is initiated by the PS II which begins the chain at 680nm.

If light exceeds the 680 nm then, PS II will remain inactive and thus will abrupt the dissociation of the water molecule and thus the formation of oxygen during the light-dependent phase.

Thus, option-A is the correct answer.

What determines the types of chemical reactions that an atom participates in? Is it the number of electrons in the outermost she
eduard
The number of electrons in the outermost shell determines essentially the type of chemical reactions that an atom participates in it is because these electrons are involved in chemical reactions as they can be donated, shared and thus rearranged by forming covalent bonds to produce new substances

There is a risk that __________ can be transferred when using stem cells in medical treatments. What word completes the sentence
Rina8888 [55]

Answer:

Bone marrow transplantation

Explanation:

Stem cells are special cells generated in bone marrow. This can changed into different types of cells. They are  red blood cells It carries oxygen to the body cells .White blood cells Resisting agents from infections . Platelets it performs clotting of blood

Stem cell transplant involves in removing of damaged cells instead placed stem places from blood or bone marrow
