Answer:
C. Elongation.
Explanation:
The RNA strand "elongates" due to the addition of new nucleotides
Answer: Meselson & Stahl reasoned that these experiments showed that DNA replication was semi-conservative: the DNA strands separate and each makes a copy of itself, so that each daughter molecule comprises one "old" and one "new" strand. The semi-conservative model, in which each strand of DNA serves as a template to make a new, complementary strand, seemed most likely based on DNA's structure. ... From the patterns of DNA labeling they saw, Meselson and Stahl confirmed that DNA is replicated semi-conservatively.
Explanation:
Lysosomes ( common in animal cell but rare in plant cells) contain hydrolytic enzymes necessary for intracellular digestion in white blood cells that eat bacteria) lysosomes contents are carefully released Into the cytoplasm can also cause cell death.
Peroxisomes: this organelle is responsible for protecting the cell form its own production of toxic hydrogen peroxide. As an example, white blood cells produce hydrogen peroxide to kill bacteria .The oxidative enzymes in peroxisomes break down the hydrogen peroxide into water and oxygen.
Secretory vesicles: cell secretions –e.g, hormones, neurotransmitters, are packaged in secretory vesicles at the Golgi apparatus. The secretory vesicles are then transported to the cell surface for releases.
In this case, the two species have coevolved by modifying behavioral traits (moths) and physiological traits (bats).
<h3>What is coevolution?</h3>
Coevolution is a particular type of evolution where a selective pressure imposed by one species serves to generate an adaptive change in another species and vice-versa.
Coevolution is fundamental in predator-prey relationships and leads to the emergence of new traits that are selected by natural selection.
In conclusion, the two species above have coevolved by modifying behavioral traits (moths) and physiological traits (bats).

The protein components which reside on the red blood cell membrane and which determines blood type are THE ANTIGENS.
Antigens are proteins molecules which are found on the surface of the red blood cell, the antigens that are present in the cell determine the type of blood that will be present in the individual. There are four types of blood; A, B, AB and O. <span />
