How does the immune system work together with the circulatory system to function properly? A.
The immune system's red blood cells fight and destroy foreign antigens.

B.
White blood cells move through the body (to parts where they are needed) in the blood vessels of the circulatory system to destroy pathogens.

C.
The circulatory system's arteries cause the immune system to work harder by bringing oxygen-depleted blood to the infection site.

D.
Red blood cells released by immune cells cause increased blood flow to the infection site; this increased blood flow brings other red blood cells to the area more quickly.

Answers

Answer 1
Answer: The answer is probably B because white blood cells are part of the immune system, so help to fight diseases. The circulatory system helps to move the white blood cell around the body. Also, pathogens are disease causing organisms, and as you can see, they all relate very well. Hope i helped, have a nice day.

Mitochondria and chloroplasts are two types of

Answers

Hey there,

Mitochondria Have DNA. Mitochondria and chloroplasts have striking similarities to bacteria cells. They have their own DNA, which is separate from the DNA found in the nucleus of the cell. And both organelles use their DNA to produce many proteins and enzymes required for their function.

Hope his helps if so please mark brainiest!

Final answer:

Mitochondria and chloroplasts are two types of organelles present in cells. Mitochondria produce ATP, the cell's main energy source, while chloroplasts in plants and algae conduct photosynthesis.

Explanation:

Mitochondria and chloroplasts are two types of specialised structures, or organelles, found within cells. They each play critical roles in energy( in different forms) provision for the cell.

Mitochondria, often referred to as the 'powerhouses of the cell', generate most of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy.

On the other hand, chloroplasts are found in plant cells and some algae. They are responsible for photosynthesis, a process by which sunlight, carbon dioxide, and water are converted into food for the plant.

Read the passage to answer the question. Even though scorpions are related to spiders, there are many differences between the two organisms. One difference is that scorpion young do not hatch from eggs as spiders do. Scorpions are born live, two at a time, and they immediately crawl onto the mother's back for protection and care. They remain there for two weeks as they grow big enough to take care of themselves. Question 2 Baby scorpions are born with fully developed bodies, each with many special parts such as a stinging tail. Which process enables baby scorpions to develop various kinds of body parts from a single zygote?

Answers

The process that enables babyscorpions to develop various kinds of body parts from a single zygote is cell differentiation. The correct option is 4.

What is cell differentiation?

The process by which dividingcells change their functional or phenotypical type is known as cell differentiation.

All cells, it is assumed, derive from stemcells and acquire their functions as they mature. Cellular composition is frequently represented as a hierarchical scheme, with stem cells at the top.

Cell differentiation refers to the process by which stem cells become more specialized. Cell differentiation is important because it creates diversity in life on Earth, diversity within our bodies' cells, and allows cells to form unique structures that fit their individualizedfunctions.

Cell differentiation is the process by which baby scorpions develop various body parts from a single zygote.

Thus, the correct option is 4.

Ribosomes are organelles that create proteins. Cells use proteins to perform important functions such as repairing cellular damage and directing chemical processes. ... Without these ribosomes, cells would not be able to produce protein and would not be able to function properly.

Bacteria and viruses have different mechanisms and machinery to survive and replicate. Because of this, there are different ways of treating bacterial and viral infections. What is a difference in the way that bacterial and viral infections are treated medically?A) Viruses can be treated with antibiotics, bacteria cannot.

B) Bacteria can be treated with antibiotics, viruses cannot.

C) Vaccinations provide immunity from viruses, but not bacteria.

D) Vaccinations provide immunity from bacteria, but not viruses.

Answers

Answer:

That is correct on USATestPrep

Explanation:

Bacteria can be treated with antibiotics, viruses cannot.

Antibiotics won't treat viral infections because they can't kill viruses. Viruses are not living and depend on a host cell to provide the machinery for reproduction.

B) Bacteria can be treated with antibiotics, viruses cannot.

Antibiotics have no target when dealing with viruses. Antibiotics work on bacteria because it targets the growth machinery in bacteria. Viruses are found inside a human cell and reproduce by inserting their DNA into a human cell. There are antivirals and vaccines out there for viruses. Our body’s immune system fights against viruses with antibodies!
