Answer:
Yes Asha is correct because when she mixed the purple berry with water into the chemical it changed color.
Explanation:
Carbon monoxide (CO) is an odorless, colorless, and tasteless gas that is toxic in high enough concentrations. It can be a by-product of burning fossil fuels. CO binds irreversibly to the protein (hemoglobin) that transports O2 throughout your bloodstream. As you are exposed to high amounts of CO over a period of time your available hemoglobin becomes unable to bind to O2 because it is bound to CO. In your own words, explain what would happen to cellular respiration and what overall effect this would have on the organism.
Answer:
Carbon monoxide has much more affinity for the hemoglobin than the affinity of the oxygen to the hemoglobin almost 300 times more, which allows the Hb to bind with carbon monoxide irreversibly. Due to this, the small quantity of CO can also reduce the ability of oxygen transport of the hemoglobin.
Longer exposure of CO to the cHb will lead to reducing oxygen release by the Hb that is bound to oxygen in this T state which causes less oxygen availability. In aerobic oxidation mechanisms like oxidative phosphorylation will eventually stop. It will be shifted to anaerobic cellular respiration. The net production of ATP drastically reduced due to anaerobic glycolysis. Cells will eventually start to die causing the death of an organism.
Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses?
options: Although both rely on other living organisms to survive, viruses are usually beneficial.
Although both rely on other living organisms to survive, parasites feed on the host organism.
Although both are living organisms, viruses break down dead plants and animals that other organisms use.
Although both are living organisms, parasites depend on the cells of living things to reproduce.
Answer:
The second statement clearly differentiates the pathogens best. Parasites feed on living host while viruses depend on the cells of other organisms to survive and reproduce as they cannot function outside a living host.
Although both rely on other living organisms to survive, parasites feed on the host organism. The correct option is B.
What are parasites?A parasite is an organism that lives on or in the host and obtains its food from or at the expense of the host.
Protozoa, helminths, and ectoparasites are the three main types of parasites that can cause disease in humans.
They frequently go unnoticed because they have few symptoms. However, these infections frequently result in serious illnesses such as seizures, blindness, heart failure, and even death.
A parasitic relationship takes place when one lifeform, the parasite, feeds on another organism, the host, causing harm and possibly death.
The parasite lives on or in the host's body. Tapeworms, fleas, as well as barnacles are examples of parasites.
Thus, the correct option is B.

What acts as the final destination for chromosomes during mitosis?
Answer:
Telophase
Explanation:
if you're asking what the final stage of mitosis is called
Answer:
Telophase
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.

Explanation:
Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question. Construct at least two possible hypothesis for the students experiment
Answer:The student's observations before he starts his experiment are that his tomato plants grew faster and taller with his artificial fertilizer rather than without any fertilizer at all.

1. Identify one population of organisms shown in the food web, other than rabbits or mice, that would likely be affected by the introduction of snowy owls AND explain why their population would be affected.
2. State which level, a, B, or C, contains the least total available energy. Support your answer.
Answer:
The population if snakes will decline because there will be competition between snakes and snow owls. The snow owls will eat the mice, but if there's only a small population of mice. Only a few snakes will eat, other snakes will die of starvation. There will be competition between snow owls, hawks and mountain lions, but they have other sources of food, unlike snakes.
Level C contains the least amount of energy. This is because each level gets less and less energy per meal, beacuse energy is released by each organism.

What is the purpose of a control in this experiment?
Question 9 options:
The control is the tube that only has milk in it.
The control is the one tube that we know will show milk digestion.
The control is the one tube that we know will not show milk digestion.
The control is the only one the scientist changes.
Answer:
I can't definitively answer this because I don't know the experiment, but I can help.
Explanation:
The "control group" of an experiment is like a dry simulation, where there is no variables changed across all the different trials you do. This is different from a dependent variable or an independent variable. Using your newfound knowledge of what a control group is you can automatically cross off the last option.
Since I cannot see what your experiment was I can't give you which of the top 3 answers it is however. You need to look at which one has no change.
If I were to blindly guess I would say the top option seems like the most likely answer.

what is the difference between mitosis and meiosis?

Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
AZT is a drug that is commonly used to fight HIV infection. The active component of AZT is a nitrogenous base that mimics thymine. Normal nucleotides CANNOT covalently bond to the thymine mimic. HIV's reverse transcriptase enzyme will use the thymine mimic instead of using thymine, whereas our DNA polymerase will not make this mistake. What is the most likely explanation for how AZT prevents HIV replication
AZT works by selectively inhibiting HIV's reverse transcriptase, the enzyme that the virus uses to make a DNA copy of its RNA. Reverse transcription is necessary for production of HIV's double-stranded DNA, which would be subsequently integrated into the genetic material of the infected cell to produce its proteins. All reverse transcriptase inhibitors are analogues of the naturally occurring deoxynucleotides needed to synthesize the viral DNA and they compete with the natural deoxynucleotides for incorporation into the growing viral DNA chain.
