Prokaryotes, such as bacteria, can live without a nucleus, because they still have genetic material (DNA), within their cytoplasm. The genes within this cytoplasmic, circular DNA can transcribe and translate these genes into functional proteins. These functional proteins can then govern the structure and function of the cell(s).

How many rings does chlorophyll a and b have

In-s [12.5K]

Explanation:

Each has one chlorin ring- chlorin is a form of porphyrin.

Chlorophylls are comprised of a ringed molecule, chlorin, a hydrogenated form of porphyrin which contains a magnesium ion at the center, bonded to four atoms of nitrogen. Varying types of Chlorophyll have side chains, which affect the absorption spectrum of the molecule for instance A has a methyl group bonded to the C7 position, while B has an aldehyle (CHO) group at this location.

Embedded within the thykaloid membrane of chloroplasts, chlorophyll a and B mainly absorb orange-red and violet-blue wavelengths and convert light energy into chemical energy for the process of photosynthesis. This occurs in the light-dependent reactions of photosynthesis, within chloroplasts of plants. The range of wavelengths absorbed by a pigment is its absorption spectrum while it reflects those outside of this range. Plants appear green as this region of light is reflected by the pigments.

The client may be suffering from a neuroleptic malignant syndrome (NMS) which is a reaction to his antipsychotic medication. NMS is rare but
life-threatening and is characterized by high fever, muscular rigidity(that's why he can't move his arm), altered mental status hyperthermia, and autonomic dysfunction.

Since is life-threatening, it requires immediate treatment.
