Looking at the chart provided, the students need to develop a classification scheme to distinguish plant and animal cells. The presence of which of the following structures/organelles would be most useful for this purpose?
Answer:
The correct answer would be - cell wall and chloroplast
Explanation:
The cell wall and chloroplast both are the main characteristic feature of the plant if present together in any cell of organisms. In most of the cells other than plant cells, the cell wall and chloroplast does not present together.
The cell wall is the outer rigid structure of plant cells made up of cellulose provide support and injuries. Chloroplast is the major and important structure of the plants responsible for their color and production of glucose by the process known as photosynthesis.
These two organelles would be most useful as all other organelles are similar and found in all cells given in the chart.
A change is a single nitrogenous base can cause a mutation called which of the following
A. evolutionary mutation
B. point mutation
C. micromutation
D. zoomatic mutation
Answer:
The correct answer is - option B. point mutation.
Explanation:
A genetic mutation occurs due to a change in a single nucleotide base, either inserted or deleted from the genetic material (DNA or RNA) sequence, which represents the mutation called a point mutation.
It can take place by the substitution of the single nucleotide sequence in DNA or RNA in the genome of the organism, it is also known as substitution mutation.
Sickle cell anemia is an example of the point mutation that takes place due to a change in a single nucleotide sequence.

TO PEOPLE WHO HAVE THIS ASSIGNMENT:
The answer is below:
A red blood cell that’s just returned from delivering oxygen and brought back carbon dioxide would be in the right atrium. When the atrium contracts, the cell is pumped into the right ventricle. When that ventricle contracts, the red blood cell is pumped out of the heart through the pulmonary artery to the lungs.In the lungs, the red blood cell enters tiny blood vessels that come into close contact with the walls of the alveoli air sacs of the lungs. The carbon dioxide in the red blood cell passes through the walls into the alveoli while the oxygen in the alveoli air passes into the red blood cell. The red blood cell then returns to the heart via the pulmonary vein.From the pulmonary vein, the red blood cell enters the left atrium of the heart and then the left ventricle. The red blood cell is pumped out of the aorta artery and eventually reaches the capillaries leading to the individual cells. There the cells absorb the oxygen from the red blood cell and pass on their waste carbon dioxide. The red blood cell returns to the right atrium of the heart via the veins to complete the cycle.
The circulatory system transports blood and other materials into the lungs and blood vessels.The circulatory system works with the respiratory system to make sure that oxygen-rich blood can flow through the body.
The respiratory system is where gas exchange occurs in the heart, arteries, veins, and capillaries.The respiratory system supports your circulatory system with air, or more specifically oxygen, which is sent to other organs from the arteries.
Here is an example:
My model is different from the actual system because I didn’t include the lungs and it is not the real thing. It is also different because in real life, the heart would not be cut in half.Some of the limitations of a model are that it doesn't move like a real heart would and you wouldn’t be able to see it in action.
why is left lung smaller than right lung
Answer:
I guess I should guess sit correct.
Explanation:
if the left lung's size is equal to the right lung's size, then there wont be any space for the heart.
so the space left on your left lung is occupied by the heart.
hope it helps :)

1.) when Dr. bass works cases, either cold cases or ongoing investigation,, what is his role in the investigation?
2.) what role does body farm play in forensic science?
3.) what is the “sniffer”? Why could this development be important
4.) are insects a fool-proof way to determine time of death? Why or why not?
5:) why are family members or law enforcement personnel sometimes interested in having people live dr bass take a look at a cold case?
Answer:
1. When Dr. Bass works cases, either cold cases or ongoing investigation, what is his role in the investigation?
Dr. Bass’s role in an investigation is helping to identify the body and giving clues on how they died or how long they have been dead.
2. What role does the Body Farm play in forensic science?
The Body Farm plays an important role in forensic science because it has given all possible education and information on the decomposition of bodies.
3. What is the “sniffer”? Why could this development be important?
The sniffer is a mechanical device that you carry in your hand and walk across the grounds of the Body Farm. The sniffer will pick up some compounds of decomposing bodies.
4. Are insects a fool-proof way to determine time of death? Why or why not?
Insects are a great predictor of how long a body has been dead if the body is outside where the insects can get to it.
5. Why are family members or law enforcement personnel sometimes interested in having people like Dr. Bass take a look at old cases?
Family members and law enforcement personnel are sometimes interested in having someone like Dr. Bass because a forensic anthropologist can help solve and close cold cases even if decades have gone by.

male and female rabbit were placed in a deserted habitat with a good supply of water and food. which will most likely happen to the rabbit population?
A. Naturally-occurring bacteria will infect the rabbits, leaving them unable to reproduce.
B. The rabbits will not adjust to their new Habitat.
C. The rabbits will breed, increasing the size of the population until the carrying capacity is reached.
D. predators will come into habitat and kill all of the rabbits.
Answer:
C. The rabbits will breed, increasing the size of the population until the carrying capacity is reached.
Explanation:
Answer:
The answer would be "C"
Explanation:
This is because there would be no predators able to eat them, no other animals interfering with them, and enough food for them to not be worrying about finding food instead of reproducing.

Describe the
relationship
between the age
of rock layers and
a fault
Answer: The relative age of a rock, then, is its age in comparison with other rocks. ... The principle of cross-cutting relationships states that a fault or intrusion is younger than the rocks that it cuts through. The fault cuts through all three sedimentary rock layers (A, B, and C) and also the intrusion (D)
