Answer:

d. RNA polymerase II.

Explanation:

The main enzyme responsible for RNA synthesis is RNA polymerase, which <em>catalyzes the polymerization of 5'-triphosphate ribonucleosides (NTP) </em>directed by a DNA mold.

Eukaryotic cells contain <u>three types of nuclear RNA polymerases</u> that transcribe different types of genes. Protein-encoding genes are transcribed by RNA polymerase II to give mRNA.

When joints are not regularly moved through their entire range of motion, muscles and ligaments eventually _____. a. shorten b.
zhuklara [117]

Answer:

a. shorten

Explanation:

Inability or failure for joints to move through their entire range of motion is caused by constrictions. These constrictions often results when the excess adipose tissues that surrounds the muscles and ligaments are not in required adequate proportion. These constrictions can be caused by ageing, fatigue, muscular diseases etc. As a result of these constriction in the joints, let say for example, the knee joint, the muscle and ligaments tends to shorten in length.

Differentiate between density-dependent and
Setler [38]

Answer/Explanation:

Density-dependent limiting factors are non living and biotic factors that affect the size and growth of a population based on the population density, while density-independent limiting factors are those factors that do not depend on the density of a population before they can have an effect on the growth and size of the population.

Examples of density-dependent limiting factors are predation, disease, Parasitism, competition. These rely on the density of a population in order to affect the growth and size of a population.

On the other hand, examples of density-independent limiting factors are pollution, flood, temperature.

Mercury is one of the densest planets in the Solar System. Venus is the brightest object we see in the sky, has a thick toxic atmosphere and is the hottest planet. Earth is the only planet that has liquid water.Mars surface contains iron-rich materials and has the most interesting terrain: the surface is very old and filled with craters.
