Answer:
Skeletal muscle contractions help maintain body temperature. (Ans. E)
Explanation:
Skeletal muscle contributes to maintaining temperature homeostasis in the body by producing heat. Muscle contractions require energy & produce heat as a by-product of metabolism. All types of muscles produce heat, but a large amount of Skeletal muscle found in the body, so it contributes greatly to heat production.
This is noticeable during extreme cold environment shivering produces random skeletal muscle contractions to generate heat to maintain the body temperature.
Skeletal muscle contractions pull (drag) on tendons, which are joined to the bones present in the body. If the contraction of muscles causes the muscle to shorten, the bone (present in the body) & other body part will start to move. Then the energy comes from a skeletal muscle produces heat & maintain the body temperature.
Answer:
a catalyst
Explanation:
Catalyst is a substance that influences the rate of reaction without being consumed in the reaction. They increase the rate of reaction by decreasing the activation energy of the reaction. In biological system, enzymes are referred to as biological catalyst or biocatalyst. They are generally protein in nature and are very specific for their substrate. They also increases the rate of biological reaction by forming enzyme-substrate complex.
hope this helps and have a good day :-)

There
are three principles to keep in mind when predicting the sequence of
the mRNA produced by transcription of a particular DNA sequence.
The RNA polymerase reads the sequence of DNA bases from only one of the two strands of DNA: the template strand.The
RNA polymerase reads the code from the template strand in the 3' to 5'
direction and thus produces the mRNA strand in the 5' to 3' direction.In
RNA, the base uracil (U) replaces the DNA base thymine (T). Thus the
base-pairing rules in transcription are A→U, T→A, C→G, and G→C, where
the first base is the coding base in the template strand of the DNA and
the second base is the base that is added to the growing mRNA strand.</span>
