Answer:
the job of the tRNA is to read the message of the nucleic acids or nucleotides and translate it into proteins or amino acids . it translates the mRNA. gives the Ribosome directions on what kinds of proteins to make
Explanation:
Answer:
Lipid bilayer
Explanation:
Red blood cell is surrounded by a cell membrane that separates its interior from the surrounding medium. The cell membrane is a lipid bilayer and consists of two layers of phospholipids. The polar heads of phospholipids make the surfaces of the cell membrane while their nonpolar tails are buried in its core.
The snake venom has phospholipase enzymes that digest the phospholipids into fatty acids. Digestion of phospholipids of the lipid bilayer of red blood cells would cause leakage of their content into the surroundings and loss of integrity of cells.
Answers with Explanation:
A stream’s velocity is LOWER at the bottom and edges. A stream’s invisible DISSOLVED load represents (on average) about 15% of the mass of material transported. A stream with many rapids and waterfalls is likely a YOUNG (AT THE YOUTHFUL STAGE) stream. In a meander, water flowing around the outside of a curve flows FASTER than water flowing around the inside of the curve. An oxbow lake can form near a MEANDERED stream. A DELTA is likely to form where a stream deposits sediment as it enters another body of water.
Answer: option A, B and D
Explanation:
The telomeres found at the terminal ends of eukaryotic chromosomes are long repetitive sequences that protects the DNA from being identify as a damage molecule to encourage fusion with other chromosomes. Since replication does not extend down to these 3' ends, the cell recruits the telomerase enzyme which is a ribonucleoprotein that helps to add telomeric repeats using its own RNA component as template to extend this end. Thus if mutation like a large deletion occurs in the gene encoding for this enzyme, the telomerase would not be able to associate correctly with the telomere, the catalytic center also encoding for its RNA polymerase would be altered and the enzymes will not be able to synthesize new telomeric repeats sequences
During the day, due to the presence of sunlight, the process of photosynthesis peaks over that of respiration. Photosynthesis uses carbon dioxide to make carbohydrates releasing oxygen as a byproduct. During the night, because there is no sunlight, the rate of photosynthesis drops. This, therefore, causes the rate of respiration to surpasses the rate of photosynthesis. In respiration, oxygen is consumed and carbon dioxide is released.
