Explanation:

-<u>Carbohydrates </u>act as signals or markers to help cells recognize one another.

Carbohydrates are organic macromolecules with a range of functions within organisms. They may act as energy storage, structural support, and signal molecules. Together with transmembrane proteins embedded within the membrane from the extracellular fluid to the cytoplasm, they form glycoproteins (proteins attached to carbohydrates) which function as cell surface markers .

Further Explanation:

Carbon, is the backbone of all biological life on Earth. It contains 6 electrons, with 4 on its valence shell, and thus, readily forms covalent bonds with other elements. Covalent bonding involves the sharing of electrons; in nature, this occurs with hydrogen,oxygen, nitrogen, and phosphorus as highly flexible single bonds capable of rotation; rigid, non-rotating double; and very strong triple bonds. Carbon compounds form rings, and long branched chains- thus, carbon can form macromolecules in nature.

In nature, organic compounds may be large chains of monomers form biological macromolecules which carry out many essential functions in the body. These can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P); they are found in essential organic biomolecules include, proteins, nucleic acids, lipids and carbohydrates.

Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers. Basic makeup: C, H, O -with many polar OH groups

What are the two ways that eubacteria can reproduce?

tresset_1 [31]

The two ways through which Eubacteria can reproduce are as follows:

Binary fission and Conjugation.

Thus, the correct option for this question is C.

<h3>What is Eubacteria?</h3>

Eubacteria may be defined as a prokaryotic microorganism that primarily consists of a single cell that lacks a nucleus and contains DNA in a single circular chromosome. It also lacks other membrane-bound cell organelles.

During the process of binary fission, Eubacteria divide into two separate daughter cells through mitosis. While during the process of conjugation, two Eubacteria cells of the same or different species connect using the pili and exchange their genetic material.

Conjugation is partially considered a type of sexual mode.

Therefore, binary fission and conjugation are the two methods through which eubacteria can reproduce. Thus, the correct option for this question is C.

A science class is checking to see how much life exists in local streams. The students predicted their water sample would only h

guapka [62]

Answer:

In the last step of the scientific process when they compare their results.

Explanation:

The scientific process can be described of the following steps in order:

Starting with the observation, finding a point that asks a question which will be investigated, constructing a hypothesis that can be tested, testing the hypothesis and lastly comparing the results and starting over.

The example given in the question has a question to investigate, the students have a hypothesis. They test it and find out that the water sample can hold 20 amoeba which does not match their predictions. The students will check if their results match their predictions in the last step of the process when they compare their results with their hypothesis.

I hope this answer helps.
