Answer: B - Breaking the bonds in a disaccharide
Explination: Just took the test.
There are 46 chromosomes in each cell at metaphase II in meiosis in humans. Normal human body cells each have 46 chromosomes. Prior to meiosis, the DNA replicates and each cell gets 92 chromosomes.
A germ cell in the testis in Metaphase II of Meiosis has 23 chromosomes.
In Metaphase II of Meiosis, the chromosomes line up at the equator of the cell and are ready to be separated into two daughter cells. Each daughter cell will receive half the number of chromosomes as the parent cell. In humans, the diploid number of chromosomes in a somatic cell is 46, while the haploid number of chromosomes in a germ cell is 23.
Therefore, in Metaphase II of Meiosis, a germ cell in the testis would have 23 chromosomes.

B. daffodils.
C. chrysanthemums.
D. lisianthus.
They explained aspects of genetics that required Watson and Crick's data to be understandable.
They needed mathematics to prove their data, and that field was not developed at the time.
They required supporting evidence which could not be provided with the existing technology.
Correct answer: D). They required supporting evidence which could not be provided with the existing technology.
Both the scientist Gregor Mendel and Alfred Wegener proposed their idea but the scientific community do not believe to their ideas they talk about genetics and DNA and at that time the technology was not developed to study such information. So, they prove their ideas and theories but are not able to explain them to the people.
Hence, the correct answer would be option D.
