Answer:
All—yeast, euglena, and paramecium—exhibit heterotrophic mode of nutrition.
Explanation:
Yeast needs to feed on subtrates (or substances) like sugars, euglena can make its food like plants do and also feeds on other food sources, while paramecium feeds on bacteria often.
Both of them produce mucus.
Nucleic acids, proteins, carbohydrates, and lipids are the four major types of biomolecules that form all living things. These biomolecules consists of monomers linked together by covalent bonds to form polymers.
- Nucleic acids, proteins, carbohydrates and lipids can be classified according to their basic elements, monomer constituents, and functions.
Basic elements:
- Nucleic acids: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Phosphorous (P)
- Proteins: Hydrogen (H); Carbon (C); Oxygen (O); Nitrogen (N); Sulfur (Z)
- Carbohydrates: Hydrogen (H); Carbon (C); Oxygen (O)
- Lipids: Hydrogen (H); Carbon (C); Oxygen (O); Phosphorous (P)
Monomer constituents:
- Nucleic acids: nucleotides
- Proteins: amino acids
- Carbohydrates: monosaccharides
- Lipids: fatty acids and glycerol
Functions:
- Nucleic acids: contains the hereditary information to synthesize proteins
- Proteins: regulate metabolic processes (enzymes), the main biomolecule of cellular structures
- Carbohydrates: store energy (short term); form cellular structures
- Lipids: store energy (long term); the main component of biological membranes
Examples:
- Nucleic acids: DNA and RNA
- Proteins: lactase; collagen
- Carbohydrates: starch (polysaccharide); glucose (monosacharide)
- Lipids: phospholipids; cholesterol

Answer:
In the United States there are existing state laws to protect people from genetic discrimination in areas such as insurance companies and workplaces.
Explanation:
Genetic discrimination is based on the possibility that an individual manifests a disability or inherited disease due to a genetic alteration.
In many cases, both workplaces and insurance companies require genetic testing before granting a job or an insurance policy.
A federal law - Genetic Information Nondiscrimination Act or GINA - protects people against this requirement of their future employers or any insurance company and guarantees, with certain exceptions, the possibility of obtaining a job or medical insurance.
