Answer:

they bind to protein-coupled transmembrane receptors with higher complexity than those found in prokaryotes

Explanation:

G-proteins are proteins found inside the cells that function as molecular switches which are activated by binding to guanosine triphosphate (GTP), while they are inactive by binding to guanosine diphosphate (GDP). The G-proteins bind to G-protein-coupled transmembrane receptors (GPCRs) in the cytoplasmic region. The GPCRs are a very diverse group of proteins that are activated by extracellular molecules ranging from small peptides to large proteins, including pheromones, neurotransmitters, light-sensitive compounds, etc, thereby allowing them to respond to diverse stimuli from the extracellular environment. In consequence, it is reasonable to suppose that the signaling pathways in which G proteins are involved have a higher complexity level than those observed in primitive prokaryotic organisms.

Alexxandr [17]

Answer:

Endonucleases

Explanation:

<em>Endonucleases are involved in DNA repair. The repair can be a base-excision repair, nucleotide excision repair or mismatch repair.</em>

Endonucleases are of different types and the type that will involve in DNA repaid depends on the type of repair that is required. It include deoxyribonuclease I and restriction endonuclease/restriction enzymes. The former cleaves DNA without taking note of the nucleotide sequence while the later is specific in the sequence of nucleotides it cuts.

________ is the differences between hemispheres in the areas underlying language function.

Ronch [10]

Lateralization is the differences between hemispheres in the area underlying language function.
The lateralization of brain work is the propensity for some neural capacities or subjective procedures to be more predominant in one hemisphere than the other. The medial longitudinal fissure isolates the human mind into two particular cerebral hemispheres, associated by the corpus callosum.
The left hemisphere orders dialect capacities, math, rationale, and the right hemisphere summons visual-spatial abilities, instinct, feeling, and creative and melodic aptitudes.

You are suffering from Streptococcus throat infection. You share the following with the bacteria that is responsible for your co

adell [148]

Answer: B) You both are made up of cells.

Explanation:

The Streptococcal infections in humans spread from one person to another through nasal and throat secretions from infected people or by direct contamination of the injury or wound. The Streptococcus bacteria can be transmitted from animals to humans and from human to animals.

The Streptococcus bacteria and humans are living organisms and they are made up of cells. This is the common feature in both organisms.The Streptococcus is a bacteria, which is made up of prokaryotic cells but we humans are composed of eukayotic cells. We humans have genetic material resides in the nucleus whereas in the Streptococcus no well defined nucleus is present and the genetic material in bacteria floats freely in the cytoplasm.
