Answer:
CU, in the periodic table. Stomic number 29.
The macromolecules broken down by following enzymes are:
- Nuclease: Nucleotides
- Sucrase: Sucrose
- Lipase: Lipids
- Pepsin: Peptides
Enzymes are the biological catalysts. They function to catalyze the chemical reactions inside any living organism. These enzymes act upon certain molecules called substrates, carry out the reaction in an accelerated manner and then form the product.
Nucleotides are the molecules involved in the formation of genetic material like DNA and RNA. A nucleotide itself is composed of three components: a pentose sugar, a nitrogenous base and a phosphate group. The pentose sugar is different for DNA and RNA. For DNA, it is deoxyribose sugar, whereas for RNA it is ribose sugar.

Answer:
What are viruses?
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea.
How are they different from bacteriophages?
Virus: ↑ A type of microbe that can infects cells. Human viruses infect human cells, plant viruses infect plant cells, etc. Bacteriophage: ↑ A virus that infects bacteria, also called a phage. DNA: ↑ The molecule that carries all the information in the form of genes needed to produce proteins.
Answer:
'Cross experiments done by Morgan, illustrating the X-inheritance link of a mutation Thomas Hunt Morgan moved intensely in a program of breeding and crossing miles of fruit flies at New York University in a room that was renamed the Fourth of the Flies. He tried to mutate the flies with various means (X-rays, centrifuges, etc.) .The fruit fly which has 4 pairs of chromosomes. One of those pairs was identified as containing X and Y sex chromosomes. He applied Mendelian principles in flies. Morgan's inheritance study demonstrated inheritance linked to sex, and is one of the first evidences that confirm the chromosomal theory of cross-based inheritance. In 1909, Morgan detected a fruit fly (Drosophila melanogaster) with a strange mutation which he called "white eyes", due to the coloration of his eyes (contrary to normal, which is red). Analyzing this fly under the microscope Morgan discovered that it was a male, and could use it as a stallion so that he could observe how the new characteristic of white eyes would pass from generation to generation.All the offspring of this cross will have red eyes, which He made Morgan suspect that something strange had happened, since the color of the father's eyes could not have disappeared. He decided to take a couple of "daughters flies" and cross them together, just to see what happened. Morgan's surprise was very great, observing that among the "granddaughters" flies only males had white eyes. The problem then was to explain what had happened during the hereditary transmission for the color of the white eyes only the males possessed. .
