The right answer is b. Glucose + fructose -> sucrose
Sucrose is a carbohydrate composed of a molecule of glucose associated with a molecule of fructose by a glycosidic bond. It is therefore a diholoside (or disaccharide in the old nomenclature). They also called α-D-glucopyranosyl- (1↔2) -β-D-fructofuranoside and its formula is C12H22O11.
Yes. During meiosis Diploid (2n) mother cell produces fou haploid(n) daughter cell.
Explanation:
- Meiosis is also known as Reduction division.
- It is type of cell division by which a diploid mother cell produces haploid daughter cell.
- It is termed as reduction division because the number of chromosomes are reduced to half in daughter cell.
- Meiosis occurs only in sex cells to produce gametes.
- Significance of meiosis lie in the fact that it reduces the number of chromosome into half and thus helps to maintain the chromosomal number of the species in the zygote after fertilisation .
- Meiosis has two steps : Meiosis I and Meiosis II. There is a time gap between two steps, called interkinesis.
- Meiosis I involves replication , crossing over etc.
- Meiosis II is similar to mitosis however, no DNA replication occurs prior to meiosis II and the DNA content is thus halved in Daughter cell.
Answer:
A. pH relates to relative acid-base ion balance in a solution
Explanation:
PS. The ocean is slightly alkaline ;)
Answer:
B
Explanation:
Tertiary structure is the overall three-dimensional structure resulting from folding and covalent cross-linking of a protein or polynucleotide molecule. This is what is explained in this question.
It binds lactose which changes its conformation so that is no longer binds to DNA. This allows the lactose operon to be transcribed.
