A single base substitution can occur in the first, second, or third position of a codon. Propose which position the point mutation is most likely to go unnoticed.
Why? Use examples from the codon wheel to support your answer.
Answers
The first, second, or third positions of a codon can all experience a single-base replacement. What position is the highest likelihood that the point mutation will go undetected? In the third slot, a substitute has the highest chance of going unnoticed.
What would happen if a substitution occurred in the first or second base of a codon?A mutation known as a substitution is one that switches one base for another (i.e., alters just one "chemical letter," for as changing an A to a G). A codon may be changed to one that codes for a different amino acid, which would result in a minor modification to the protein that is made.For instance, twofold degenerate codons can withstand silence mutation rather than Missense or Nonsense point mutations at the third position, whereas fourfold degenerate codons can tolerate any point mutation at the third position, although codon usage bias restricts this in practice in many organisms.If a base substitution takes place in the codon's third position, there is a strong likelihood that a synonymous codon will be produced. The mutation is referred to as silent since the gene's encoded amino acid sequence is unaltered.To Learn more About single-base replacement Refer To:

DNA is a structure made up of two coiled polynucleotide chains with nitrogenous bases present in chromosomes. These chromosomes are present in the nucleus of the cell. These cells together form an organism.
What are Cells?Cell is define as the smallest unit which can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts:
1. The cell membrane
2.The nucleus
3. The cytoplasm.
A nucleus is defined as the membrane-enclosed organelle within a cell that contains chromosomes. It is an array of pores, or pores, in the nuclear membrane that allow the selective passage of certain molecules, such as proteins and nucleic acids, into and out of the nucleus.
Chromosomes are define as the threadlike structures made of protein and a single molecule of DNA which serve to carry the genomic information from cell to cell. These DNA (Deoxyribonucleic acid) is a polymer which is composed of two polynucleotide chains that coil around each other to form a double helix consisting of nitrogenous bases.
Thus, DNA is a structure made up of two coiled polynucleotide chains with nitrogenous bases present in chromosomes. These chromosomes are present in the nucleus of the cell. These cells together form an organism.

How are adaptations passed to offspring?
Group of answer choices
Adaptations skip generations in organisms. Even if one organism "learns" an adaptation, it will be their "grandchild" organism that gets it.
Adaptations are mostly random, as they are genetic. They are written in the DNA. Changes in genes are random. If a mutation happens and the offspring of two parents has a mutation, sometimes that mutation will help it live.
The parents develop during their lifetime, so their DNA changes, and when they mate, the adaptation and then pass it on to offspring
Parents purposely CHOOSE which adaptations they give to their offspring, because they can choose which half of their genes are going to go into that organism, and predict how it will mix with it's mates genes. it is planned out to ensure species survival. This is especially true in flowering plants.
Answers
In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.
Therefore, the answer is :
Adaptations are mostly random, as they are genetic. They are written in the DNA. Changes in genes are random. If a mutation happens and the offspring of two parents has a mutation, sometimes that mutation will help it live.

With the release of enzyme, enzyme take part in the chemical reaction without utilizing in it.
When the enzyme release by any glands in the body, it attached to the substrate and speed up the chemical reaction without using in it. Once the chemical reaction ended, the enzyme which attached the substrate earlier detached and then attached other substrate in order to speed up the chemical reaction.

Why do cells continue to divide in adult organisms?
Answers
Answer:
Although most of the tissues in adult organisms maintain a constant size, the cells that make up these tissues are constantly turning over. Therefore, in order for a particular tissue to stay the same size, its rates of cell death and cell division must remain in balance.
Explanation:
There are two main reasons why cells divide rather than continuing to grow larger and larger: The larger a cell becomes the more demands the cell places on its DNA. If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Why does cell division remain important to an adult organism even after it is fully developed? It remains important because cells are renewed and wounds are healed in the process. When cells stop dividing to specialize in structure and function. When cells undergo programmed cell death.
