The only way to tell if the red blood cells are crenated is to observe them under a microscope
What is crenation?Crenation is the process of red blood cells becoming misshapen and breaking apart, and this can be seen through the examination of red blood cells under a microscope.
By observing the shape of the red blood cells, it can be determined if they are crenated or not. Additionally, other methods such as hemoglobin analysis or measuring the osmotic fragility of the red blood cells can also be used to determine if crenation has occurred.

Critical Thinking When lipid is added to a solution of a detergent in water, the detergent breaks
up large globules of the lipid into much smaller globules. What effect do you think a detergent would
have on the integrity of cells? Explain your answer.
Answer: The cell would break apart.
Explanation:
Because Detergent breaks apart lipids, it would destroy the phospholipid bilayer, causing the whole cell to fall apart.

Design a controlled experiment to determine the effect of hot, dry air on head lice. In your experimental design, be sure to:
• state the hypothesis to be tested in the experiment [1]
• state one way the control group will be treated differently from the experimental group [1]
• state one result of the experiment that would support the hypothesis [1]
An experiment is carried out to answer a question. The hypothesis predicts what is expected to occur. Experimental and control groups are compared to analyze the results, supporting or not the hypothesis.
-----------------------------------------
BACKGROUND
When people are infested with head lice, it is recommended to wash their cloth and dry it with hot air over 53 or 54ºC for 5-30 minutes.
Head lice and eggs seem to die when exposed to those conditions by getting dehydrated.
SITUATION
We will assume that we work in a primary school and that students from the 3rth grade are being affected by this parasite.
We want to know if applying hot air to these students before entering the class will make a difference and help to control this problem.
So, we will propose an experiment to answer this question.
HYPOTHESIS
A hypothesis is a conjecture. A researcher hypothesizes to predict what is going on or what is expected to occur. The hypothesis is a claim of how it works a relation between two or more variables. Usually, it is written in the present time.
Hypothesis ⇒ Applying hot air to students' heads kills the head lice that students are carrying.
To evaluate the effect of hot air, we need to keep control of as many other variables as possible.
To do so, we asked students' families not to use other treatments on students' heads and to bathe them daily.
In this way, we were sure that all students
were equally affected by the parasite, took showers every day, and neither was using any other product that could affect the results.Our population was the 3rth grade students ⇒ 64 children ⇒ 30 girls + 34 boys.
Before the experiment, we separated the 3rth grade into two groups.
Group A ⇒ 32 students ⇒ 15 girls + 17 boys ⇒ Experimental groupGroup B ⇒ 32 students ⇒ 15 girls + 17 boys ⇒ Control group
→ Treatment
Each student from group A received hot air every day for one week before entering the class.
Hot air was 53ºC and was applied for 5 minutes.
→ Control
Each student from group B did not receive the treatment for one week before entering the class.
CONTROL GROUP
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
Individuals of the control group are selected from the same population as the treatment group.
*** These two groups are identical in all aspects except for the independent variable, which changes in the treatment group but remains constant in the control group. ***
The control group is Group B. The only difference between the control and the experimental group is that the first one did not receive the treatment. Every other aspect was equal for both groups.
The only way the control group was treated differently from the experimental group was that the control group did not received the treatment, while the experimental group did.
RESULTS
After one week, groups were compared to see if the hot air was effective in killing head lice.
When comparing the control and the experimental group, we could see that students from group A were free of parasites.
Students from group B were still affected by the head lice.
CONCLUSION
The results support the hypothesis. Hot air turned to be a great treatment for lice control.

How does bromothymol blue act as an indicator for carbon dioxide? What evidence do you have to support your conclusion?
Answer:
Carbon dioxide production can be measured by breathing through a straw into a solution of bromothymol blue (BTB).
Explanation:
BTB is an acid indicator; when it reacts with acid it turns from blue to yellow. The more carbon dioxide you breathe into the BTB solution, the faster it will change color to yellow.

Explanation:
The volume (V) of a cylinder can be determined by using the formula
V = ar?h,
where r = the radius of the base, and h = the height of the cylinder. What is the result
of solving this equation for r?
Answer:
Explanation:
To solve for r, simply means to isolate the variable:
[tex]V = pi*r^2*h\\[/tex]
The inverse of multiplication is division, so divide both sides by pi and h
[tex]\frac{V}{pi*h} = r^2[/tex]
[tex]r = \sqrt\frac{V}{pi*h}[/tex]
what is metaphase and what does it do?
Answer:
Metaphase is the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to spindle fibers. A metaphase separates duplicated genetic material that is carried in the nucleus of a parent cell and then converts it into two identical daughter cells.
Answer:
Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. As metaphase continues, the cells partition into the two daughter cells.

What is happening to the chromosomes in this phase of mitosis?
Answer: The answer is A
During mitosis (nuclear division), the chromosomes condense, the nuclear envelope of most cells breaks down, the cytoskeleton reorganizes to form the mitotic spindle, and the chromosomes move to opposite poles. Chromosome segregation is then usually followed by cell division (cytokinesis).
