Due to its small size iodine easily passes the membrane and charges glucose, hence iodine is a molecule that is permeable and glucose is impermeable.
Which molecule is permeable and impermeable?Because the tubing was iodine permeable, the contents of the bag became blue-black, indicating the presence of starch.
Glucose also easily flowed through the membrane's pores. After completing Benedict's test on the solutions, both the bag's and the beaker's liquids became brown.
Iodine molecules are tiny enough to pass readily across the membrane, but starch molecules are complex and too huge. Because it passed through the dialysis tube and interacted with the starch, iodine was permeable.
Therefore due to the small size of iodine and its charge with glucose, the permeable molecule is iodine and the impermeable is glucose.

What happens when the chemical bond that holds the third phosphate is broken?
Answers
The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).
What is phosphate bond?
The structural structure of nucleic acids, including DNA and RNA, is composed of the sugar-phosphate backbone.
This molecule's directionality is determined by this backbone, which is made up of alternating sugar and phosphate groups.
Nucleotides make up DNA and RNA, and they are connected to one another in a chain via chemical interactions between their neighboring nucleotides' phosphate groups and sugar bases.
Therefore, The second and third phosphate groups' chemical connection is a high energy bond. ADP is created when that link is disrupted and energy is released (adenosine diphosphate).

Vaccines are given to provide protection against pathogen causing infections. Which of
the following statements best describes how vaccines work?
Answers
Answer:
vaccines basically have the virus they are fighting in them to get the white blood cells in our bodies to know how to fight that virus in the case we do get it
Explanation:
Answer: Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself. Regardless of whether the vaccine is made up of the antigen itself or the blueprint so that the body will produce the antigen, this weakened version will not cause the disease in the person receiving the vaccine, but it will prompt their immune system to respond much as it would have on its first reaction to the actual pathogen.

Amino acids are named after two of their functional groups: the amino group (NH2), which acts like a base, and the carboxyl group (COOH), which acts like an acid. Amino acids also contain a third functional group, often called the R group. In alanine, the R group is a methyl group (CH3). In serine, the R group is a methyl alcohol (–CH2OH).
A molecule of alanine is shown next to a molecule of serine. Each molecular structure has an amino group (NH2) on the left side, and a carboxyl group (COOH on the right side.
What functional groups will be joined together if alanine and serine molecules combine to form a single molecule?

What is amino acids?Amino acids are molecules that join together to form proteins. Amino acids are the building blocks of living organisms. Proteins are broken down into amino acids which is the end product of protein digestion and it is easily absorbed into the body. Amino acids help to build cells, synthesize hormone and neurotransmitters.
Amino acid is divided into essential and non essential amino acids.
The essential amino acids are not synthesised by the body but they are taken up as food supplements and they include that include leucine, isoleucine, histidine, lysine, methionine, threonine, phenylalanine, tryptophan, and valine.
Non-Essential Amino Acids are Amino acids that are synthesised by our bodies. Examples include aspartic acid, glutamic acid, alanine, glycine, tyrosine, serine.
Therefore, The functional group alanine and serine molecules when they combine to form a single molecules an amino group and a methyl group.
