Elenna [48]

Answer: synthesize a pre-rRNA 45S (35S in yeast), which matures and will form the major RNA sections of the ribosome. RNA polymerase II synthesizes precursors of mRNAs and most snRNA and microRNAs. RNA polymerase III synthesizes tRNAs, rRNA 5S and other small RNAs found in the nucleus and cytosol.

the nutrients in foods perform functions in the body, what are they and briefly describe the nutrients involved in these functio

Ludmilka [50]

Answer:

The human body needs a list of macromolecules and micromolecules for performing day to day functions.

The essential macronutrients that the body requires are:

Carbohydrates: Carbohydrates are required by the cells in the body to carry out normal day to day functions. Energy is provided in the form of calories by the carbohydrates.

Proteins: Proteins are essential nutrients which are required for growth as well as better functioning of the immune cells of the body.

Fats and oils: These are needed for providing insulation to the body and to store energy.

Fibres: These are a mixture of carbohydrates.

Water: Almost every activity of the body requires water.

The essential micronutrients that the body requires are:

Vitamins: Vitamins are a group of substances which are needed by the body to function normally.

Minerals: Mineral are needed to ensure that tissues are working correctly.

How is the ruminant digestive system different than human digestive system?

bulgar [2K]

background info:

Digestive system in animals is an important system in the context of digestion of ingested food into simpler forms that could be easily absorbed by the body cells.

This provides all the essential compounds needed by the body for the existence and development of the living organism. Different digestive systems have evolved according to different species, their feeding patterns, and their habitats.

answer:

Ruminant species survive only on plant matter. They are herbivorous animals.

Therefore, the digestive system of ruminants is evolved with the presence of a rumen which is a complex stomach with four different compartments.

Humans are omnivorous who depend on plant and animal matter both thus, their digestive system composes of one stomach.

This is the key difference between digestion of humans and ruminants.

What are the differences in their hard parts, distribution, reproduction among phytoplankton of cyanobacteria, diatom, coccolith

Margarita [4]

Answer:

Explanation:

DIFFERENCES BETWEEN HARD BODY PARTS.

•Cyanobacteria have calcified sheaths.

• Diatoms have hard but porous cell wall.

• Coccolithophores have hard body parts.

• Silicoflagellates skeleton is composed of opaline silica.

• Dinoflagellates do not have hard body parts

• Green algae - no hard body parts.

• Brown algae - no hard body parts.

DIFFERENCES BETWEEN DISTRIBUTION

• Cyanobacteria are found almost in every terrestrial habitat on planet.

• Diatoms are found in oceans, freshwater, soil and damp.

• Coccolithophores are exclusively marine.

• Silicoflagellates are found in marine environment.

• Dinoflagellates are both freshwater and marine.

• Green algae grow on objects that do not move such as substrate, rock.

• Brown algae - wide distribution from tropical to polar zones.

DIFFERENCES BETWEEN REPRODUCTION.

• Cyanobacteria - asexually by binary or multiple fission, fragmentation, spore formation.

• Diatom - asexually by cell division through mitosis.

• Coccolithophores - asexually by binary fission.

• Silicoflagellates - asexually

• Dinoflagellates - asexually

• Green algae - sexually or asexually by cell division, fragmentation, spore formation.

• Brown algae - sexually and asexually.
