_____ act as signals or markers to help cells recognize one another.

Varvara68 [4.7K]

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 is Sickle cell anemia?

Sickle cell is an autosomal recessive trait of humans that arises through mutation in normal gene. The gene for this trait is found in recessive form and you need two copies of the gene - one from father and one from mother- to have the trait expressed. If the trait is expressed it causes a disease called sickle cell anemia.

People with the sickle cell anemia disease have red blood cells of crescent or sickle shape. The red blood cells of this shape can cause many complications in body. They get stuck in blood vessels and cause pain. They also die quickly and make a person anemic (pale).

Probability to have a child with sickle cell anemia:

If a mother is normal but a father is carrier for the trait, then the situation will be as:

Here N indicate normal allele, S indicate allele for sickle cell anemia.

Mother ˣ Father

NN NS

Gametes: N N N S

Offspring: NN NS NN NS

50% : Normal

50% : Carrier

0% : Sickle cell anemia

It means that 50 % kids will be normal and 50% will be carrier for the trait and none of the offspring will have disease Sickle cell anemia. However, those who are carriers can carry the disease to the next offspring if they are married to a carrier or a person with sickle cell anemia.

18. Some unicellular organisms are motile (have the ability to move) and some are nonmotile. Which cellular structures are assoc

LiRa [457]

Answer:

D, Flagella

Explanation:

Ribosomes produce proteins for the cells to function, chloroplasts provide a plant cell with photosynthesis, vacuoles provide a plant cell with holding its structure up, and mitchondria provides ATP (energy) for the cell to function.
