Answer:
Depolarized graded potential.
Explanation:
A depolarizing graded potential is a local change in the membrane potential that makes a small increase in the potential. The membrane potential is less negative because the graded potential caused the entrance of Ca²⁺ or Na⁺ ions to the inside of the cell decreasing the negative voltage in the inside of the cell.
All of these are necessary
Answer:
RNA sequence- 5' AUG 3',
tRNA anticodon- 3' UAC 5'
Amino acid- methionine
Explanation:
DNA contains two strands of sense and antisense. The mRNA sequence is produced by the antisense strand of DNA. So if the DNA sense strand has ATG sequence then according to the complementary base pairing the sequence against it would be 3' TAC 5'.
In RNA in place of thymine, Uracil comes so here according to complementary base pairing rule the sequence of codon in RNA would be 5' AUG 3'. As tRNA contains anticodon sequence which is complementary to mRNA codon sequence therefore the anticodon sequence would be 3' UAC 5'.
Every triplet codon in mRNA codes for a particular amino acid and AUG codon is called start codon which codes for methionine. So methionine would be added against AUG codon.
Answer:
d) A and B above.
Explanation:
Triacylglycerols are the simplest form of lipids comprised of fatty acids. Triacylglycerols are also called as fats or neutral fats. Each molecule of triacylglycerol is composed of three fatty acids bonded to the single glycerol molecule.
Each of the three fatty acids of triacylglycerol is bonded to glycerol in an ester linkage. The main function of triacylglycerols is to serve as energy storage form and provide insulation to eukaryotic cells.
Photosynthesis and cellular respiration basically are dependent on one another. Photosynthesis produces a product of glucose, and oxygen as a byproduct. Cellular respiration uses both glucose and oxygen to produce carbon dioxide and water which are needed for photosynthesis to occur. Humans, animals and plants depend on the cycle of cellular respiration and photosynthesis for survival.
