Protists can be:________.
PilotLPTM [1.2K]

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.

Chap 2.3 biology;;
Murrr4er [49]

Answer:

Monomer: 2 - Amino acid

                 3 -Nucleotide

Polymer: 1 - Cellulose

               3 - Nucleic acids

Example: 1 - Carbohydrates

               2 -  Collagen

Function 1: Carbohydrates are a source of energy in the body.

Function 2: Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.

Function 3: DNA is a protein structure that carries instructions needed for an organism to develop, survive and reproduce. It is a nucleic acid that contains the genetic instructions for the development and function of living things, its main role is the long-term storage of information

Explanation:

Monomers are single molecules that can bond with identical molecules to form polymers.

1. Glucose can combine with other glucose molecules to form starch or cellulose which results in formation of carbohydrates.

Carbohydrates are a source of energy in the body.

2. Amino acids can combine with other amino acids to form a protein chain which results in formation of collagen

Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.

3. Nucleotides can combine to form nucleic acids resulting in formation of enzymes.

DNA is a protein structure that carries instructions needed for an organism to develop, survive and reproduce. It is a nucleic acid that contains the genetic instructions for the development and function of living things, its main role is the long-term storage of information
