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).

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:

A

Explanation:

The reason of why meiosis contributes to genetic variations is because of option A. it increases the ratio of mitosis within an organism.

Since the recombination and the non-dependent assortment in meiosis, each gamete comprise the different DNA set. It generated the unique combination of genes that should lead to zygote.

Also, it rises the mitosis ratio within an organism

Hence, the option A is correct.

Explanation:

All of the things found in the Earth system can be categorized into four (4) main categories and these includes;

I. Land: this subsystem forms a sphere which is generally referred to as litosphere.

II. Water: this subsystem forms a sphere which is generally referred to as hydrosphere. It comprises of landforms such as mountains, valleys, plateaus, ridge, rocks, etc.

III. Air: this subsystem forms a sphere which is generally referred to as atmosphere. This sphere comprises of gases such as oxygen, carbon dioxide, nitrogen, etc.

IV. Living organisms: this subsystem forms a sphere which is generally referred to as biosphere. It comprises of all living things such as humans, animals and plants.

If humans change the function or equilibrium of one of Earth's systems, this will significantly change the function or equilibrium of all of Earth's systems. Consequently, these changes result in environmental phenomenon such as volcanoes, earthquakes, tornadoes, wildfire, etc.

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.

The chemical formulas are aluminum bromide (AlBr₃), magnesium bromide (MgBr₂), sodium sulfide (Na₂S), and the chemical compound formula of the sodium nitride is Na₃N.

Chemical formulas are important to identify the chemical composition of the mixture as they provide important information about the types and numbers of atoms present in a molecule or compound and also predict the properties of a substance, such as its melting point and boiling point. This is useful in industries such as manufacturing, agriculture, etc which has significant importance in the field of medicine, as it helps researchers understand how the human body interacts with the drug.

Hence, the chemical formulas are aluminum bromide (AlBr₃), magnesium bromide (MgBr₂), sodium sulfide (Na₂S), and the chemical compound formula of the sodium nitride is Na₃N.

Answer:

I'd say true

Explanation:

Mass of the molecules diffusing: Heavier molecules move more slowly; therefore, they diffuse more slowly. The reverse is true for lighter molecules. ... Because cells primarily use diffusion to move materials within the cytoplasm, any increase in the cytoplasm's density will inhibit the movement of the materials.

Answer:

False

Explanation:

As the density of a solvent increases, the rate of diffusion decreases. The molecules slow down because they have a more difficult time getting through the denser medium. If the medium is less dense, diffusion increases.

The correct answer is - prokaryotic and unicellular.

Explanation:

Eubacteria is known as the true bacteria and belongs to the prokaryotic type of cells which is characterized by no double-membrane organelles or the nucleus. All the genetic material is present in the cytoplasm itself.

These bacteria are single-cell microscopic organisms as they are very minute to see by the naked eyes and required a microscope to study. Another word for the single-cell organisms is unicellular.

Explanation:

Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

Explanation:

The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.

With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.
