Answer:
e) unicellular, colonial, or multicellular.
Explanation:
Protists originates from the Kingdom Protoctista. They comprise of organisms that are unicellular (Amoeba) or unicellular-colonial (volvox) in nature and which have no tisssues, therefore they are at the cellular level of organization.
Examples include, Amoeba, Paramecium, Euglena, Slime mold, Kelp, Diatoms, DInoflagellates. etc.
Some of them are also considered to be multicellular eukaryotes e.g slime molds, red algae etc. Eukaryotic organisms are organisms that possess cells containing a nucleus.
Characteristics in which protists exhibit varies from one species to the other.
For example, the mode of nutrition in eukaryotic algae are autotrophic in nature, in amoeba, they are gifted with pseudopods(false feets) in which they used to engulf prey(a term known as phagocytosis) therefore making them to be heterotrophic in nature.
In protist, locomotion varies from one organism to another. For example, in Amoeba , locomotion is achieved by extending and retracting pseudopods, Euglena are flagellated in nature , hence they move with the flagella. In Paramecium that are ciliated in nature, they move by propelling their cilia. etc.
K+ channel opens, resulting potential -90mV
This is due to hyperpolarization.
<h3>What is hyperpolarization?</h3>
- Hyperpolarization is a change in a cell's membrane potential that makes it more negative (i.e. decreases).
- It results in increase in the potential difference across the membrane.
- K+ moves from the inside to outside as some potassium channels remain open and sodium channels reset. A period of increased potassium permeability results in excessive potassium efflux before the potassium channels close.
- K+ channels typically cause membrane potential to become more negative.

Answer:
1. Synthesis and repair of muscle tissue
2. Production of ATP
3. Synthesis of glucose
Explanation:
Proteins are primarily used for tissue repairs and synthesis. They are polymers of amino acids used to make hormones, enzymes and other chemicals of the body. Therefore proteins are only reserved for synthesis and repairs of tissues.
During extreme starvation periods when then is no source of carbohydrates and adipose tissues has been depleted/used up, proteins are alternatively used as source of energy in form of amino acids that enters the liver. Tissues such as muscles are protein degraded to provide the brain with energy in form of ketone bodies and glucose, thus the weight loss in people suffering from malnutrition.
Monomer can be a good name of a molecule because it can form other molecules through reactions.
Explanation:
The organic molecule that is able to react with different molecules resulting in the formation of other molecules is the ‘monomer’. Its significant feature is its multiple functionality or poly functioning.
With this feature it can form chemical bonds with other monomers. The feature of polymerization of condensation can be found in the monomers with more than two groups of atoms.
The aspect and areas of the dental office that should be assessed is the customer service units. The patient- dental assistant relationship should be enhanced.
<h3>Who is a dentist?</h3>
A dentist is an individual that specialises in diagnosis, treatment and prevention of diseases that is associated with the gum, teeth and mouth.
When creating a list of improvement that would enhance the dental office setting, the customer service unit should be assessed. This is because it is the point where the patient and the dental assistant has first point of contact.
The manner of approach of the dental assistance to these patients needs to be improved as patients who are not well received can stop coming to the clinic.
