Answer: a molecule made of many small molecules
Explanation: Macromolecules are large molecules that are composed of smaller molecules called monomers. These macromolecules are polymers of the monomers units. Examples of macromolecules are proteins which have amino acids as their monomers and carbohydrates which have monosaccharide sugars such as glucose, and fructose as the monomers.
The right answer is A.
Plant species are particular in their ability to produce oxygen and carbohydrates through photosynthesis. The plant, just like the animals also needs to breathe so that these cells survive, so it is forced to take some of the oxygen and carbohydrate produced by photosynthesis to operate these cells through cellular respiration.
Answer:
48 amino acids
Explanation:
The wild type gene codes for a protein with 100 amino acids. One amino acid is encoded by one triplet code of the gene. This means that the wild type gene has a total 100 triplets or 300 nucleotides to code for a protein of 100 amino acid. Mutation in this protein has introduced the code "UAA" at the 49th codon. The code "UAA" is a stop codon. Therefore, the mRNA transcribed from the mutant allele would code for a protein having 48 amino acids as the protein synthesis will be stopped once the stop codon at the 49th position is read.
The third one is the correct answer I hope this helped
The movement of substances (as by diffusion) across a cell membrane without the expenditure of energy.
