_____ 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

Cerebral palsy was once thought to be the result of something that happened during the birth procedure, but we now know that it

Dmitry [639]

Answer:

Explanation:

Cerebral Palsy is a brain injury it occurs while the brain is developing this could be before, during, or after birth. Mutation which is a sudden heritable change in the genome of an individual can result into cerebral palsy when the child is still developing. Mutation affects the gene changing it from it normal state to an abnormal one some mutation can be beneficial but for palsy it is detrimental one affecting the growth and development of the child.

severe jaundice in the infant could also lead to cerebral palsy in an infant child

This damage affects child’s muscle control, muscle coordination, muscle tone, reflex, posture and balance.

It can also impact a child’s fine motor skills, gross motor skills, and oral motor functioning

Wild-type E. coli grow best at 37 but can grow efficiently up to 42 . An E. coli strain has a mutation of the sigma subunit that

igor_vitrenko [27]

Answer:Temperature- Sensitive Mutation, C

Explanation:

AT 37°C ,<u> The organism transcribe a wild type--C.</u>

The type of mutation exhibited by the mutant bacterial strain is a Temperature- Sensitive Mutation. This is because at different temperatures, the organism transcribes differently ie transcribes at wild-type levels at 37°C and completely denatures and ceases to carry out transcription at 42°C .
