Environmental impact and radioactive waste
At the end of cellular respiration must be right
Answer:
36750J
Explanation:
Potential energy, which is the energy of a body at rest or in a position is calculated as follows;
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity = 9.8m/s²
h = height of the boulder (m)
According to the provided information;
m = 25kg, h = 150m
Using P.E = m.g.h
P.E = 25 × 9.8 × 150
P.E = 36750 Joules
Answer:
1. transcription of mRNA from DNA
2. small ribosomal subunit binds to mRNA
3.initiation complex formed with addition of large ribosomal subunit
4.codon recognition (non-initiating site)
5.peptide bond formation
6.translocation
7. ribosome reads a stop codon
8.polypeptide chain is released from the P site
9. ribosomal subunits dissociate
Explanation:
The translation is a process which translates the nitrogenous bases or codons in the proteins.
The process of translation requires the mRNA, tRNA and ribosome and proceeds in three stages: the initiation, elongation and the termination.
The process begins with the binding of the small subunit of the ribosome to the mRNA. The charged tRNA with a first amino acid called methionine binds the mRNA and scans the mRNA until it finds the start codon.
After it finds the start codon, the large subunit complex binds the mRNA and form initiation complex. After this, the amino acid enters the P-site of the ribosome where elongation of peptide takes place.
The peptide then exits from the E-site and the ribosome dissociates.
<h2>Answer is option "B"</h2>
Explanation:
- Our brain requires an enormous measure of vitality and so as to meet this needs the progression of blood must be accurately arranged to guarantee that oxygen is being conveyed where it is required and when it is required.
- Vitality in the mind is created solely from a type of digestion that requires oxygen. However, neurons just keep up a little save of vitality and these cells require a constant inventory of oxygen, particularly when the cells are terminating and speaking with their neighbors.
- Blood dashing through a brain district's trap of vessels is an indication that nerve cells in that region have kicked vigorously. The blood races to dynamic territories to supply terminating neurons with the oxygen and glucose they require for vitality.
- Hence, the correct answer is option B "Active areas of the brain take up more oxygenated blood than they need for their energy requirements"
