Answer: they take nutrients from food
Explanation:
Cells get energy by taking in nutrients from food. Cells get energy only by taking in oxygen from the atmosphere.
All organisms interact with and depend upon each other and their environment to satisfy their basic needs. Relationships between organisms include predation, competition, and symbiosis. Consider the food web. Select ALL of the relationships that exhibit competition for resources.
Answer:
Explanation:
Relationships in the food web that show competition for resources include:
Herbivores competing for producers. Carnivores competing for herbivores. Carnivores competing for other carnivores. What are some examples of competition in the food web?Competition in the food web involves organisms of different species trying to use the same resource.
A herbivore such as a cow competing with another herbivore such as a goat, to eat grass (producer) shows competition.
Leopards and Cheetahs competing for a rabbit shows carnivores competing for herbivores.
Then carnivores and omnivores such as lions and humans can compete for other carnivores as well such as jackals.

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.

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).

The equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy
CELLULAR RESPIRATION:
Cellular respiration is the process by which living organisms obtain energy by breaking down food molecules.Cellular respiration can occur in the presence of oxygen (aerobic) and this combines glucose molecule to form carbon dioxide (CO2) and water (H2O) and release energy for use. The general equation for cellular respiration is as follows:C6H12O6 + 602 = 6H20 + 6CO2 + Energy
Therefore, the equation best models cellular respiration is: C6H12O6 + 602 = 6H20 + 6CO2 + Energy (ATP).Learn more at: https://brainly.com/question/13721588?referrer=searchResults

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]
Which statement is a hypothesis that would best address the question "Are rainbow trout eating all the macroinvertebrates in streams and starving out other fish species?" If rainbow trout are eating all the macroinvertebrates, then keeping rainbow trout out of new river habitats will allow native species to recover. If rainbow trout are eating all the macroinvertebrates, then introducing them to other streams will help native species recover. Rainbow trout will eat a variety of macroinvertebrates and native fish species. Rainbow trout hunt and prey upon native fish species.
A possible hypothesis here is; "If rainbow trout are eating all the macroinvertebrates, then keeping rainbow trout out of new river habitats will allow native species to recover."
A hypothesis is a statement that is tentatively put forward to explain an observation. Usually, a hypothesis is an if .... then statement. This is one of the first things that we must look out for when considering each of the statements.
Since we have observed that rainbow trout eating all the macroinvertebrates in streams and starving out other fish species, it follows that keeping rainbow trout out of new river habitats will allow native species to recover."

Explanation:
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.
