C. Bacteria are multicellular
viruses have no DNA or RNA so they can't be unicellular or multicellular
The right answer is A) DNA.
During evolution, the mitochondria have retained their own genome, which, although very small compared to that of a bacterium, is essential for the proper functioning of these organelles. Confined within the mitochondria, organelles that produce cellular energy, the mitochondrial genome (mtDNA) is distinct from the DNA in the nucleus. The transmission of this DNA is generally called non-Mendelian because it is only transmitted by the mother.
Chloroplasts contain DNA grouped into nucleoids; each chloroplast can contain up to 100 copies of the genome. The DNA molecules of the chloroplast genome are generally linear or branched. The chloroplast genome is very small, 37 to 220 kb and usually contains about a hundred genes
Answer: 1. Disaccharide
2. two monosaccharides, galactose and glucose
3. the role of lactase is to catalyse the hydrolysis of the disaccharide lactose to yield the monosaccharides galactose and glucose
Explanation:
Lactose is a disaccharide, consisting of two monosaccharide units joined by a beta 1–>4 glycoside link
Lactase cleaves the glycoside link, giving two monosaccharides, galactose and glucose
Autotrophs are able to live without heterotrophs.
