Biology
1 answer:
bekas [8.4K]3 years ago
5 0

Answer: The correct answer is option B.

Explanation:

A scientific model is physical,conceptual or mathematical representation of real phenomena or process which cannot be directly observed.

A drawing of a atom is a scientific model to understand the or to get picture of it in an individual mind. Atom are smallest unit of the matter which are not visible to human eyes.

A light powered microscope is an instrument which works on principles of reflection, refraction, and optics in physics which.

Formation of cloud is also explained by the help of model. Formation of clouds is a chemical process which can not be observed or seen directly with help of healthy human eye.

So, from the given options. option which is not in accordance with the definition of scientific model is option B.

Investigate four substances containing nitrogen or phosphorous that are related to biological processes, and explain their respe
OleMash [197]

Answer:

Well, you already have the answer, but I can try to elaborate XD

So, DNA: contains genetic information that is necessary for biological functioning and reproduction.

More specifically, it contains the genetic instructions through gene encoding that instructs the cell what to do. A specialized complex ribosome interacts with the DNA molecules and "reads" it, changing the genes from the DNA into proteins that the cell as a whole can function upon. It is also crucial to forming a whole cell in offspring, since only the genes from the two parents combined (in humans at least) can produce an offspring with all genes intact. Those who do not have genetic disorders, a famous one being Down Syndrome.

Next, RNA: a molecule necessary for expressing genes and making proteins.

Connecting to the paragraph above for DNA, RNA also assists in the process by reading the ribosome that reads the DNA itself. Complicated, I know. All you have to know, however, is that the RNA, in this case called mRNA since it serves as a messenger, hence, the "m", reads the codons produced by the ribosome when it reads the DNA, and makes proteins according to those codons, and those proteins then scatter all across the cell to execute instructions.

Now, we move onto nitrogen and phosphorous: both are found in amino acids, the building blocks of proteins.

That is actually partially wrong. Amino acids do not contain phosphorous, but do contain nitrogen. Not exactly sure what went wrong on your end there, but nitrogen is a basic building block for amino acids, which are basic building blocks themselves for proteins. To be more clear, amino acids are made of carbon, hydrogen, oxygen and nitrogen atoms. No phosphorus there!

Finally, enzymes: special proteins that accelerate chemical reactions in cells.

This is correct. Enzymes typically lower the activation energy required for reactions to happen. More specifically, enzymes make the reaction molecules more active, hence, lowering the threshold for the amount of energy you have to put in before the molecules start crashing into each other hard enough to have a chemical reaction. Of course, enzymes do not participate in the reaction itself, which makes them incredibly useful for spurring on chemical reactions since they can be used multiple times.

Explanation:

Hope this helped!
