Which of the following normally leads to the production of functional messenger RNA in eukaryotic cells?

Answers

Answer: The removal of portions of RNA known as intervening sequences (introns)

Explanation:

The removal of portions of RNA is known as intervening sequences (introns).

What is the process of splicing?

In order to enable the translation of mRNA into a protein, RNA splicing puts together the protein-coding regions (exons) and cuts out the intervening, non-coding segments of genes (introns) from pre-mRNA.

Intron sequences are cut out and exon sequences are joined during the splicing process.

As RNA matures, introns are cut out via RNA splicing, which means that they are not expressed in the resulting messenger RNA (mRNA) product.

In contrast, exons continue to be chemically bound to one another to produce mature mRNA. Exons are expressed sequences, whereas introns can be thought of as intervening sequences.

Therefore, the removal of portions of RNA is known as intervening sequences (introns).

Answer:

muscles

exchange

Explanation:

Your diaphragm, and muscles between your ribs, make air move in and out of your lungs. It travels through the trachea, bronchi, and bronchioles to alveoli. In the alveoli, oxygen diffuses into the blood and carbon dioxide leaves. This is gas exchange.

Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.

d. All of the above

Explanation:

All of the given choices are reasons to study the ocean carbon cycle. The ocean occupies about 70% of the earth surface area and it plays important roles in carbon cycling.

The ocean acts as reservoir for carbon in many different ways especially due to the dissolution of this gas in it. It also releases a significant amount of carbon dioxide to the atmosphere due to the plethora of life within it. The field is also relatively new and more works must be done to understand this cycle.

Answer:

The last answer

Explanation:

The sun is a perpetual resource because solar radiation steadily streams from the sun without interruption and is expected to do so for the next 6 billion years.

What do you mean by perpetual resource?

Perpetual resources are those that last forever like solar energy and wind. Non-renewable resources, once extracted completely from a given area, will never be available in the same spot again (except after millions of years).

Perpetual resources are natural resources—such as solar energy, wind, and tides—that have no chance of being used in excess of their availability. They can be used for power generation and conversion to electric energy.

Sunlight, wind, geothermal heat, tides, and flowing water are perpetual resources. On Earth, there are only limited amounts of fossil fuels such as oil, coal.

Suppose that this population of mice has stabilized so that both white and brown appear. White mice survive better in the winter and brown mice survive better in the warmer months. If a group of these mice migrated to an area that didn't get snowy in the winter, what do you think would be the long term effect on the color of these mice? Explain why.

Answers

Answer:

The population of the white mice would significantly decrease, and most of the mouse population would be with brown fur.

Explanation:

As stated in the question, the brown mice survive better in warmer times. This is due to the fact that with winter and snowy times it makes it harder for prey to spot the WHITE mice v.s. the BROWN mice who would very easily be spotted by the prey in snowy regions.

Which macromolecule is needed for lactic acid formation and alcohol fermentation to proceed with their processes?


IN YOUR OWN WORDS
DONT COPY FROM THE INTERNET

Answers

Answer:

sugar

Explanation:

sugar is the required macromolecule

In the lactic acid formation, pyruvate changes to the lactose which is the anaerobic form of respiration. Pyruvate changes to alcohol and carbon dioxide.

What is the main ingredient for lactic acid fermentation ?

It is the sugar molecule that is needed for the lactic acid fermentation.

Both the  types of  the fermentation requires two primary components which are a sugar supply and  bacterial culture where alcohol fermentation uses the  forms of  the yeast where the lactic acid fermentation usually depends on  the lactic acid bacteria.

Lactic acid fermentation takes place in some of the  strains of  the bacteria and in  the even skeletal muscle and even  produces lactic acid . Alcoholic fermentation takes place in the  yeast and just  produces ethanol with carbon dioxide.

Lactic acid bacteria is a type of gram-+ve bacteria which use carbohydrates as only and main carbon source. Later on lactic acid bacteria is generally cocci or rods usually have the  strong tolerance to low pH.
