Question

1. the smallest biological unit of a living organism is a ____________. a. cell b. compound c. element 2. pairs of thread - like molecules, which live in the cells nucleus, and carries heredity information are called________________. a. chromosomes b. genes c. dna 3. made of dna this is the basic physical and functional unit of heredity. a. chromosomes b. genes c. dna 4. fully grown parent cells split into two halves resulting in two daughter cells with the exact dna as the parent. a. binary fission b. budding c. fragmentation 5. a parent cell breaks into pieces and each piece become a new offspring. a. binary fission b. budding c. fragmentation 6. which is not an advantage for asexual reproduction? a. less genetic variation b. no need for a mate c. quick

Explanation:

1. Cells are the basic structural and functional units of living organisms. Compounds and elements are non - living chemical substances.
2. Chromosomes are thread - like structures in the cell nucleus that carry hereditary information. Genes are segments of DNA on chromosomes, and DNA is the molecule that makes up chromosomes.
3. Genes are the basic physical and functional units of heredity made of DNA. Chromosomes are structures containing genes, and DNA is the larger molecule.
4. Binary fission is a form of asexual reproduction where a parent cell splits into two daughter cells with the same DNA. Budding involves an outgrowth, and fragmentation is different.
5. Fragmentation is when a parent cell breaks into pieces, and each piece becomes a new offspring. Binary fission is splitting into two, and budding is outgrowth.
6. Less genetic variation is a disadvantage of asexual reproduction. No need for a mate and being quick are advantages.

Answer:

1. A. Cell
2. A. Chromosomes
3. B. Genes
4. A. Binary Fission
5. C. Fragmentation
6. A. Less genetic variation
