Petroleum Products
Petroleum and its products are mainly composed of carbon polymers (chains), as the backbone, with different structural and functional groups. Plastic, for example, is made of polypropylene and polybutylene which is mainly made of carbon atoms, whose monomers are linked in a chain to form polymers that make up the products.
Synthetic rubber on the other hand is made of copolymers of carbon and other addictives such as styrene. Synthetic fiber is made of nylon that is composed of a copolymer between carboxylic acid and amides.
Answer: Option A
<u>Explanation:</u>
As temperature increases the rate of enzyme activity increases until it reaches approximately 37 degrees Celsius. As temperature increases beyond 37 degrees Celsius, the enzyme activity decreases. The activity decreases because the enzyme denatures.
Any enzyme has certain temperature, pH and pressure to maintain its activity. Only at the ideal or ambient parameters the enzyme works. Most of the enzymes that are present in the human body gets activated by 37 degrees and gets denatured beyond that temperature.
I think it's A not sure tho
Gizzard
Birds such as chicken, doves and others, and earthworms have gizzard which are responsible for storing and softening the consumed food in their digestive tract. The gizzard serves as the grinder of these food in preparation of the absorptive phase of the G.I tract.
<h2>Answer:</h2>
The three amino acid will be Tyrosine, Asparagine and Lysine respectively to sequence.
<h3>Explanation:</h3>
UTC GTU TTG
First the thymine in the sequence is changed to A, adenine because in the mRNA only three types of nucleotides are allowed which are Adenine, thymine and Uracil.
So the sequence will be:
UAC GAU AAG
These codons will be read by tRNA producing the polypeptide sequence of amino acids which are as follow:
Tyrosine Asparagine Lysine.
