Answer:
ribose is a major component of the energy molecule known as ATP (adenosine triphosphate).
Explanation:
The answers that apply are;
new allele combinations were advantageous in the presence of
parasites with high mutation and reproduction rates.
sexual reproduction increased genetic variability and
survival in a changing environment?
Sexual reproduction increases genetic variability due to combinations of alleles from the parents to the
offsprings. This increases the chances
that a particular combination may be able to confer resistance to the
disease-causing bacteria and hence increase the survival of the roundworms population.
Answer: The lock-and-key mechanism is usually associated with the complementary shapes of an enzyme with a single substrate wherein the lock that is being referred to is the enzyme and the substrate is the key. One right sized substrate (key) fits into the active site (key hole) of the enzyme (lock).
Answer
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
Lamarck believed that the stretching elongated the giraffe's neck, which became a useful characteristic and was passed onto future generations. This resulted in the length of the giraffe's neck increasing over time. It is now commonly accepted that Lamarck's ideas were wrong.
Having broken down walls of Glomerulus would cause blood to appear in urine because instead of only filtrate passing into the capsule, the blood would also flow into the capsule and be released with the urine.
