Answer;
-5-carbon sugar
Explanation;
-The basic repeating unit of nucleic acids are known as nucleotides. There are two types of nucleic acids, namely RNA and DNA.
-A nucleotide consists of three distinct chemical groups, a 5-carbon sugar (ribose or deoxyribose), a nitrogen-rich base - (cytosine (C), guanine (G), adenine (A), thymine (T) in DNA or uracil (U) instead of T (in RNA), and phosphate.
Nucleotides consist of a phosphate group, a nitrogenous base, and a 5-carbon sugar.
Nucleotides, the building blocks of nucleic acids, consist of a phosphate group, a nitrogenous base, and a 5-carbon sugar. The 5-carbon sugar is called a pentose sugar. In DNA, the 5-carbon sugar is deoxyribose, while in RNA, it is ribose.

Ans.
Coral reefs are underwater ecosystems, made from growth and deposition of living or dead corals. Red algae play an important role in formation of coral reefs. The thread-like structures of red algae trap the sand sediments and particles of sands and cements, which provide mechanical support to the colony of corals and help them to grow.
Thus, the correct answer is option). 'red.'
b) phylogenetic tree II
c) phylogenetic tree III
d) phylogenetic tree IV
Answer:
Your question is incomplete, but I attached the exercise with the possible phylogenetic trees and all the information that your question missed. I hope it helps you.
The most parsimoniuous phylogenetic tree is c) phylogenetic tree III
Explanation:
The most parsimonious tree is the one that takes fewer base-change events, it's the simpler one. In this case it could be tree III or tree IV. But, if we look at the genetic evidence, group 2b and 3 are nearer than 2b and 2a; group 4 and 5 are also closely related. So it is possible that the group 2b, as well as groups 3,4 and 5, diverged from group 2a. So the answer is tree III.
The most parsimonious phylogenetic tree is the one that requires the least changes in the A, C, G, T genetic sequence coding for eye growth, thereby presenting the simplest explanation of evolutionary relationships among the alien species.
The question is asking which of the four possible phylogenetic trees represents the most parsimonious, or simplest, explanation of the shared genetic sequence for eye growth among the alien species. The most parsimonious tree would be one that requires the least amount of evolutionary change in terms of the genetic sequence. This would be determined by comparing each tree and the associated genetic sequences in the way they separate the six groups of aliens and particularly how they divide the single-tail three-eye group. This should provide the simplest explanation of evolutionary relationships based on the alien's genetic code of A, C, G and T.

Answer:
Pepsin breaks the proteins into simple amino acids.
Explanation:
Digestion is the process of break down of the larger food particles into the simpler substances. The digestion process requires enzymes and digestive juices.
Proteins are made of the amino acids. The enzyme pepsin helps in the breakdown of proteins into the simple peptides. The proteins present in the test tube is hydrolyzed by the enzyme pepsin and breaks down the proteins into simpler amino acids.
Thus, the answer is pepsin breaks the proteins into simple amino acids.
