What species concepts is not very useful in defining plant species because some plant groups readily hybridize with other plant

groups?
Biology
1 answer:
matrenka [14]3 years ago
3 0

Answer:

The <u>biological species concept</u> is not very useful in defining plant species.

Explanation:

The biological species concept says that <em>species are population groups that, in a real or potential way, can reproduce and that </em><em>are reproductively isolated from other groups.</em>

<em>Individuals belonging to a species cannot reproduce with members of other species. </em>

This biological concept has limitations. Its application might present difficulties in concern with asexual reproduction species, such as bacteria, rotifer, cnidarians, plants, and etcetera.

Besides, this concept cannot be applied to the past because it is difficult to deduce reproductive capability between extinct species.

Finally, this concept is not adequate in concern to hybridization zones, something to be expected considering evolutionary processes. This is why this concept has been less accepted by botanists, as some plant species hybridize with other species. For example, species Quercus grisea and Quercus gambelii have overlapping ranges in the southwestern United States. Hybrids showing variation in leaf shape and other traits have been found in many places in this area.

Which of the following is NOT an accurate description of protein synthesis and folding?
julia-pushkina [17]

Answer:

OPTION b. "<em>The 3D shape of a protein is determined largely by the ribosome forming the protein" </em> is NOT an accurate description of protein synthesis and folding.

Explanation:

<em>a. Many copies of a protein can be synthesized simultaneously from the same mRNA</em>.  TRUE. As a ribosome moves along the mRNA chain synthesizing a new protein, another ribosome might follow it, synthesizing another protein from the same mRNA chain. And so on. So, at the same time, many ribosomes might be attached to the mRNA, synthesizing many copies of the protein, but at different development levels. The mRNA chain together with many ribosomes is called a <em>polyribosome</em>.

b. <em>The 3D shape of a protein is determined largely by the ribosome forming the protein</em>.  FALSE. What determined the 3D structure of the protein is the amino acid sequence of that particular polypeptide. Each amino-acid has different properties (hydrophobic, hydrophilic, positively charged, negatively charged) and they interact with each other by different bonds that depend on those poperties. So the amino acids composing the proteins and their interaction, is what models the structure of the protein.

c. <em>The entire chain of amino acid exits the ribosome before it begins folding into its 3D shape</em>.  TRUE. When the ribosome reaches the end codon, the elongation process has finished, and the new protein leaves the ribosome and is translocated to the RER lumen where it is going to get folded.

d. <em>The first encoded amino acid in every protein is methionine. </em>TRUE. Almost always, the first amino acid located by the tRNA is the methionine, codified by the initiation codon AUG. This amino acid is frequently eliminated at the end of the process.

A plant uses energy from the Sun to make food. What kind of energy transformation is this? a. light energy to chemical energy b.
Ulleksa [173]
The answer is <span>a. light energy to chemical energy.
</span>
<span>In the photosynthesis, plants use light energy from the sun as an energy source. This light energy from the sun is converted into chemical energy stored in carbohydrates made from carbon dioxide and water. So, when light reaches a leaf of a plant, it passes through to chloroplasts. The chloroplasts are organelles inside the leaf and contain pigment chlorophyll. Light excites chlorophyll and a series of chemical reactions occur inside the chloroplasts. As the result, carbohydrates which serve as a food for the plants </span><span>are synthesised.</span>
