How does the immune system work together with the circulatory system to function properly? A. 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 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. The immune system's red blood cells fig

What radiation is used in hospitals and how does it cause a problem for staff/workers?

Answers

Radiation is used for X-rays, MRIS, any type of cancer killing.
Too much of radiation can be a dangerous thing... you could end up dying from a lot of exposure.

The radiation used is gamma radiation. It causes a problem for staff/workers as it's highly penetrating meaning it can penetrate (go through) almost anything . The staff/workers will have a lot of exposure to this gamma radiation and too much exposure allows the radiation to kill cells, even the useful ones.

A group of organic compounds that include fats are known as _____. carbohydrates nucleic acids proteins lipids

Answers

Ans.

Lipids are a class of biomolecules, made up of fatty acids and fatty acid derivatives. Lipids are non-polar, water insoluble organic compounds, which include fats (triglycerides), steroids, phospholipids, and natural oils. Lipids play role in different functions, such as in membrane synthesis (phospholipids), energy storage (fats), and signalling (steroids).

Thus, the correct answer is option) 'lipids.'

Lipids would be your answer I believe(:

The formula Q = MCT where Q = heat flow, M = mass, C = specific heat, and T = change of temperature is used to calculate heat flow. Solve this formula for T.T = Q – MC
T = Q + MC
T = QMC
T = Q divided by the quantity M times C

Answers

Answer;

T = Q divided by the quantity M times C

That is; T = Q /(MC)

Explanation;

-Q or heat flow, or thermal energy is measured using temperature change and calculated using the formula Q= MC Δt., Where M is the mass, c is the specific heat capacity and delta t is the change in temperature.

-From the formula; To determine the change in temperature, we just divide the given formula by the product m×c, both sides,

ΔT = Q/mc

-To determine the specific heat capacity we divide both sides by the product m×delta T

c = Q/m×Delta T

To determine the mass, we divide both sides by the product c×delta T.

m = Q/c×Delta T

Answer : The correct option is, T = Q divided by the quantity M times C

Explanation :

The given formula is,

$Q=MCT$
