Scientists believe that some mass extinction events are possibly caused by asteroids, volcanic activity, or climate
change. How many mass extinctions have occurred on Earth in the last 4.6 billion years?
O 0
O 1
O 5
O 10
Answer: 5
Explanation:
The number of mass extinctions that have occurred on Earth in the last 4.6 billion years is five. Thus, the correct option for this question is C.
What do you mean by Mass extinction?Mass extinction may be defined as a type of event in which a large number of species undergo extinction within a relatively short period of geological time, due to some factors such as catastrophic global consequences, volcanic activity, asteroid explosion, etc.
Mass extinction is also known as mass diversity loss. The first mass extinction occurred in the Ordovician period, the second occurred in the Devonian period, the third occurred in the Permian period, the fourth occurred in the Triassic period, and the fifth occurred in the Cretaceous period.
The third mass extinction is the biggest mass extinction in which 90% of life forms were lost. In which 90-96% of species are extinct.
Therefore, the number of mass extinctions that have occurred on Earth in the last 4.6 billion years is five. Thus, the correct option for this question is C.

plant cells contain chlorophyll. what is the role of chlorophyll in plants?
Answer:
The role of the chlorophyll is to literally provide food for the plant by absorbing the sun.
Explanation:
That's basically the simplified way of seeing it
Explanation:
Green Plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color.:-)-XxItzAdiXxYou are solving a density problem, where density = mass/volume.

The weakest hydrogen bonds occur between which of the following?
thymine
cytosine
guanine
adenine
Answer:
Explanation:
Weakest hydrogen bond will be formed when the electronegativity difference between the atom and H is the least. Hence, S−H−−−−−H form the weakest hydrogen bond.

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.

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.
