Answer:
Option C is correct. The flow chart best shows the relationship between the cell structures is:
DNA → gene → chromosome → nucleus
Explanation:
DNA can be described as the material of inheritance.
A gene can be described as the basic unit of inheritance. It is made up of segments of DNA.
Chromosomes can be described as thread-like structures which are made up of different genes.
The nucleus is the site where chromosomes are placed. The nucleus is found in every eukaryotic organism.
Hence, the correct order for these cell structures is illustrated in option C.
Answer: Leeuwenhoek biggest contribution is to the first tenet of the cell theory.
Explanation: the first tenet of cell theory states that every living being is made of cells and even an organism can be made of just one cell able to reproduce by itself.
Leeuwenhoek observations stablish the existence of microscopic structures alive some with movement. This helped other scientists to determinate this structures were cells that can make vital processes such as feeding, breathing or reproducing which are determinant in biological definition of life.
“His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.”
<span>Answer:
100 amino acids.
Each amino acid corresponds to a codon of 3 nucleotides. Therefore, a coding region of 300 nucleotides contains 100 codons and will produce a polypeptide of 100 amino acids in length.</span>
