The correct answer is C.
Cell theory is a theory, not a law because the cell theory does not have enough support to become a law.
 Cell theory is referred to as the history of scientific theory. All cells come from pre-existing cells, and that is the basic unit reproduction and a basic unit of all organisms. The three tenets of cell theory are,
 1. cells arise from pre-existing cells.
2. The cell an organizational basic unit and structure in organisms.
3. All living organisms are composed of more or one cells. Cell theory did not become a law because the scientist who discovered it, did not give it a credit to become a law but a theory.
Since it did not have enough support to become a law.

Daniel is studying feeding relationships in a neighborhood pond. He observes several organisms that feed on one another, and he
vichka [17]

So given the suggested food chain of algae-snail-sunfish-heron we can conclude that this food chain is heavily dependent on the process of photosynthesis.

The algae is the only of the organism that are directly dependent of the photosynthesis for their survival, while the snail, sunfish, and heron, and indirectly dependent on it.

Since we are talking about a food chain, in essence it means that all organism are connected through one another. So the algae perform photosynthesis for its own survival, the snail is using the algae is a food source, the snail is later eaten by the sunfish, and the sunfish goes on the menu of the heron.

If the algae, by some scenario, are not able to perform photosynthesis, than they will die off, and if they die off, than the snail will die off because of lack of food, if the snail dies off, along with it dies off the sunfish because of lack of food, and if the sunfish is out of the scene, the heron goes as well.

So we can conclude that the process of photosynthesis is of crucial importance for the survival of all four species, be it directly or indirectly.

In classical conditioning the ns becomes a ________ after it reliably signals the impending occurrence of the ________.
nignag [31]
The answer is <span>c.CS; US.

In classical conditioning, a new behaviour is learned via association. The stage before conditioning involves: 1. unconditioned stimulus (US) which produces an unconditioned response, and 2. neutral stimulus (NS) which has no effect on a person and produce a response only when paired with </span>unconditioned stimulus. During conditioning, neutral stimulus (NS) and unconditioned stimulus (US) pair and neutral stimulus becomes a conditioned stimulus (CS). In other words, <span>the ns becomes a <u>CS</u> after it reliably signals the impending occurrence of the <u>US</u>. </span>

Reena segregates the waste at home and put the bio degradable waste in a pot containing soil. She leaves it for 15 days and uses
seraphim [82]

Answer:

Reena is making compost to reuse or recycle biodegradable waste and convert it into a natural fertilizer.

Explanation:

By placing the biodegradable matter in the pot with soil, microorganisms living in that soil are able to decompose the wastes and produce fertile products. This fertilized soil is very useful in plant care because it provides many nutrients and benefits for needed the plants' growth.

Compost consists of a controlled oxidation biological process and microorganisms and other invertebrates such as earthworms are in charge of decomposition of the solid matter. The product is used as a natural fertilizer and is a good substitute for chemical fertilizers. When composting, temperature, and humidity must be controlled. The process lasts one week or two until the whole solid wastes are degraded and mixed with the rest of the soil.

Which statements describe proteins? Select three options.
andre [41]

<u>Complete Question:</u>

Which statements describe proteins? Check all that apply.

A.) Proteins are created from the code in DNA.

B.) Proteins are synthesized in the nucleus of a cell.

C.) DNA and RNA are proteins.

D.) Amino acids are the building blocks of proteins.

E.) Proteins affect the structures and functions of living things.

F.) The shape and the function of a protein are not related.

<u>Correct Option:</u>

The statements which describe proteins are as follows:

A.) Proteins are created from the code in DNA.

D.) Amino acids are the building blocks of proteins.

E.) Proteins affect the structures and functions of living things.

<u>Explanation:</u>

Transcription is the method of RNA molecule creation from DNA. The translation is the mechanism by which the protein material is produced from the RNA molecule. Originally, protein forming data is contained in the DNA in the context of nucleotide code. The mechanism of translation happens in the cytoplasm and not at the nucleus.

DNA and RNA contain nucleotides and not proteins. Proteins are the alpha amino acid polymers, which serve as the building block of the protein. An individual's phenotype relies on the composition of the protein, and protein determines the composition and phenotypic expression in living organisms. 3D structure of proteins and their work are realized with one another.

A researcher claims that genetic variation provides organisms with the ability to survive and reproduce in different environment
Igoryamba

Answer:

The researcher's claim is in the same way of the observation made because from it it is inferred that in a population of bacteria with genetic variation, in which some of them have plasmids and others do not, the population survives because those bacteria with plasmids are resistant to antibiotics, if for example there were only bacteria without plasmids all bacteria would die when using antibiotics so this is an example that genetic diversity is an evolutionary advantage
