Answer:
Protein A can be a cytoplasmic and protein B can be a membrane protein.
Explanation:
The polar amino acid will have the hydrophilic side chain so they provide the hydrophilic nature to protein and thats why usually found on outer surface of water souluble proteins.
Cytoplasm is 80% water, so these proteins usually found in cytoplasm.
The non-polar amino acid will have the hydrophobic side chain and thus provide hydrophobic nature to protein and usually found in interior portion of membrane protein.
Plasma membrane is made up of hydrophobic lipids bilayer, so these proteins are usually found in plasma membrane.
B.
Mitosis involves somatic cells only.
they might conserve water
X-gal is included in the growth medium on which cells transformed with bacterial plasmids are grown. The reason x-gal is included is to identify bacteria that contain a recombinant plasmid.
<h3>What are
cells?</h3>
- Cells are the basic building blocks of all living things. The human body is comprised of trillions of cells. They deliver structure for the body, take in nutrients from food, convert those nutrients into significance, and carry out technical functions.
- Cells are of two types: eukaryotic, which include a nucleus, and prokaryotic cells, which do not have a nucleus, but a nucleoid province is still present. Prokaryotes are single-celled organisms, while eukaryotes may be either single-celled or multicellular.
- They deliver structure for the body, take in nutrients from food, convert those nutrients into significance, and carry out technical functions. Cells also include the body's genetic material and can make duplicates of themselves. Cells have multiple parts, each with a separate function.
