Answer:
yes because without microscope our eyes will be damaged
Both eyes must be open when looking through the microscope to prevent eye fatigue, which occurs when the non-viewing eye is kept closed.
What is Microscope?A microscope is defined as a laboratory instrument which is used to examine objects that are too small to be seen by the uncovered eye while microscopy is defined as the study of small objects and structures using a microscope.
Viewing through a microscope requires both eyes to be open to avoid eye fatigue that occurs when the non-viewing eye is closed, while keeping both eyes open requires some practice. But it is highly recommended, we should never let an eye touch an eye.
Thus, both eyes must be open when looking through the microscope to prevent eye fatigue, which occurs when the non-viewing eye is kept closed.

Proteins are sequences of amino acids joined by peptidic bonds. These sequences determine their function in cells. They characterize for expressing primary, secondary, tertiary, and quaternary structure.
-----------------------------------------------------------------
Amino acids are organic molecules. They are composed of a central carbon, one hydrogen atom, one carboxyl group, one amine group, and one R group. The composition of the R group is what makes them different from each other.
Proteins are amino acid polymers linearly arranged and connected by peptidic bonds. These molecules characterize by their different structures.
The primary structure refers to the sequence in which the amino acids are arranged in the chain. The secondary structure is the folding that the polypeptide chain adopts through the hydrogen bonds between the atoms.The hydrogen bonds are set between the -CO- and -NH- groups of the peptide bond (the first as an H acceptor and the second as an H donor). These conformations with less free energy, and therefore, more stable. The most common secondary structures are alpha-helix and beta-sheet.
Many proteins can express both secondary structures, alpha-helix, and beta-sheet.
Proteins acquire a tertiary structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water. When proteins are composed of more than one polypeptide subunit, they arrange in a fourth structure, named quaternary structure.The many functions that proteins accomplish depend on the aminoacids sequences.
So, the appropriate locations in this concept map are as follow,
a) amino acids
b) functions
c) peptide bonds
d) central carbon
e) primary structure
f) secondary structure
g) R-group
h) tertiary structure
i) quaternary structure

The pH of a solution increases as its acidity increases.
O The pH of a basic or alkaline solution is less than that of an acidic solution.
O As the concentration of H increases in a solution, the pH decreases.
O A solution to which HCl has been added will have a greater pH than a solution
to which NaOH has been added.
O Each number on the pH scale represents an increase of 108.
Question 3
Answer:
your correct answer is 3 ok
The pH of a solution increases as its acidity increases 3) A solution to which HCl has been added will have a greater pH than a solution to which NaOH has been added.
While the acidity of an answer will increase does the pH increase?As a solution gets greater acidic (as [H+] will increase), the pH decreases. As an answer receives greater basic (better [OH-]), the pH increases. Because the pH of a solution decreases through one pH unit, the attention of H+ will increase by way of ten times.
The logarithmic scale of pH method that as pH will increase, the H+ attention will decrease through the power of 10. Therefore at a pH of zero, H+ has an awareness of 1 M.
Decrease pH variety approach stronger acid, higher pH number approach the stronger base. It may be a bit difficult, but the decrease the pH of a substance, the stronger an acid it's miles.

Fishing is a major part of many Caribbean economies. The yellowtail snapper and Nassau grouper are important food fishes. However, a lack of adequate regulation has led to overfishing in many areas and consequent damage to reefs.
When grouper fishing is set to 70% what happens to the population of other fish populations in the reef?
Question 1 options:
The lack of grouper fish in the food web caused a spike in the snappers that are usually eaten by the groupers.
Since there were hardly any grouper left as a result, the snapper population also decreased amongst the reef community.
All the other fish populations in the gizmo increased as a result of the fishing favoring the grouper.
Answer:
The lack of grouper fish in the food web caused a spike in the snappers that are usually eaten by the groupers.
Explanation: because fish. (i did the test btw so i know this is correct ;)
When grouper fishing is set to 70%. The lack of grouper fish in the food web caused a spike in the snappers that are usually eaten by the groupers. The correct option is A.
What is fishing?Fishing is a technique to catch fish and other water organism for selling and food purposes. Here the topic is overfishing, which means the over-catching of fish, which disbalances the ecosystem.
In Caribbean economies, fishing is an important act. There are two main fish, groper, and snapper. But due to the deregulation of catching fishes, the grouper fishes are killing more than the snapper fishes. So this would cause a decrease in the population of groupers.
Thus, the correct option is A. The lack of grouper fish in the food web caused a spike in the snappers that are usually eaten by the groupers.
