Answer: Primary
Explanation: The primary level of protein structure explains the sequence of amino acid linked together by peptide bonds to form polypeptide chains . A slight change in the amino acid sequence of Hemoglobin can alter hemoglobin function.
The primary level of protein structure is essential in the function of the protein any alteration in the amino acid sequence can disrupt the function of the protein.

Complete Question:
Students investigated samples of amylase from 100 goats. 100 small filter paper discs were each soaked in a different sample of goat amylase. The students tested the activity of these amlyase samples using plain paper. Plain paper contains starch.
A circle of plain paper was placed into a Petri dish ad shown in the diagram below. Iodine solution was used to stain the starch in the plain paper.
When iodine solution reacts with the starch in the plain paper, what colour would you see?
Answer:
The colour that would be seen is blue black .
Explanation:
Amylase is an enzyme that is involved in the breaking down or hydrolyses of starch.
When Amylase reacts with iodine, it speeds up the rate of reaction of the hydrolysis of the starch present in the plain paper.
The colour that would be observed is a blue black colour and the starch in the paper would be broken down further more into simpler sugars.
Answer:
The correct answer is option C) phagocytosis in the inflammatory response.
Explanation:
Our body has an immune response mechanism for when we get hurt or when<u> it feels that something outside our body wants to harm us</u>, so its automatic reaction is to defend against all those bacteria and viruses that want to attack us.
The system is responsible for <u>identifying the antigens and destroying them.</u> The antigens are all bacteria, harmful viruses and dead substances that are found on the cells. Our system has its own proteins that are HLA antigens. But as these are normal for the body, it does not counterattack them.
There are <u>several defense mechanisms that work as barriers</u> to prohibit the passage of any bacteria that harm us, and one of these mechanisms is inflammation.
In this case, when our body suffers some kind of injury from a bacterium, a cut or a blow, the damaged cells release substances that spill onto the tissue through the blood vessels, causing inflammation.
This allows the foreign substance to be “locked up” and cannot enter the body.
These spilled substances also attract white blood cells, which are called phagocytes which<u> are responsible for eating dead germs and cells</u> through the phagocytosis process.
Answer:
Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.
hope this helps:)
The correct answers are B & C. Silicon-32 is the parent isotope, which decays into phosphorus-32 (daughter isotope). The silicon-32 amount is halved every 170 years, so we can use this to determine how old the rock is. The amount of phosphorus-32 increases over time, but it is not equal to the amount of silicon-32.
