What is logistic growth?

• A model where population grows rapidly and then levels off as it reaches carrying capacity.

• A model where population grows exponentially without limits.

• A model that describes a constant population size over time.

• A model that predicts population decline due to resource depletion.

What is the significance of chromosomes in genetics?

• Chromosomes are responsible for the production of proteins in the cell.

• Chromosomes carry genetic information in the form of genes, which determine the traits and characteristics of an organism.

• Chromosomes are involved in the process of cellular respiration.

• Chromosomes help in the digestion of food within the organism.

What are the components of DNA?

• A deoxyribose sugar, a phosphate group, and nitrogenous bases (adenine, thymine, cytosine, guanine)

• Amino acids, fatty acids, and glycerol

• Ribose sugar, a phosphate group, and nitrogenous bases (adenine, uracil, cytosine, guanine)

• Nucleotides, which include ribose sugar, a phosphate group, and nitrogenous bases (adenine, thymine, cytosine, uracil)

What is the difference between haploid and diploid cells?

• Diploid cells contain one complete set of chromosomes, while haploid cells contain two sets.

• Diploid cells contain two complete sets of chromosomes, while haploid cells contain only one set.

• Haploid cells are found in somatic tissues, while diploid cells are found in gametes.

• Diploid cells are produced by meiosis, while haploid cells are produced by mitosis.

What is the purpose of meiosis in sexual reproduction?

• To produce identical cells for growth and repair

• To produce gametes (sperm and eggs) with half the number of chromosomes

• To create energy for cellular processes

• To facilitate asexual reproduction

What is a nucleotide?

• A basic building block of proteins consisting of amino acids.

• A basic building block of nucleic acids consisting of a nitrogenous base, a sugar, and a phosphate group.

• A type of lipid that stores energy in cells.

• A carbohydrate that provides structural support in plant cells.

What is the process of DNA replication?

• DNA replication is the process by which a cell makes an identical copy of its DNA before cell division, ensuring that each new cell receives a complete set of genetic information.

• DNA replication occurs only during the G1 phase of the cell cycle.

• DNA replication is the process of converting RNA into DNA.

• DNA replication is the mechanism by which proteins are synthesized in the cell.

What is the haploid number of chromosomes?

• 23

• 30

• 46

• 15

What is the function of deoxyribose sugar in DNA?

• Deoxyribose sugar forms the backbone of DNA, linking with phosphate groups to create the structure of the DNA molecule.

• Deoxyribose sugar acts as a catalyst in DNA replication.

• Deoxyribose sugar provides energy for cellular processes.

• Deoxyribose sugar is involved in protein synthesis.

What is carrying capacity in an ecosystem?

• The total number of species in an ecosystem.

• The maximum number of individuals of a species that an environment can sustainably support, based on available resources.

• The minimum number of individuals required for a species to survive.

• The average number of individuals of a species in a given area.
