Answer:

Positron emission tomography (PET)

Explanation:

Positron emission tomography (PET) consists of the measurement of the physiological function by inspecting the flow of the blood, metabolic functions, radiolabelled drugs, and neurotransmitters. PET provides quantitative analyses making it possible to monitor relative changes as time passes, keeping control of the progress of a disease or how the person reacts to a stimulus. To do it, the person receives a low quantity of a radioactive tracer into his/her organism via injection.

jok3333 [9.3K]

Answer:

348.75 individuals, however you may need to round

Explanation:

To solve this problem, you need to think of the proportions you are given. Since she marked 45 fish in the beginning, and assuming none died, you can assume that there are 45 marked fish in the whole population. Therefore, when she takes the sample of 62 and sees that there are 8 marked fish, a good strategy is to take that proportion and use it to solve for the population like so:

8(marked fish in sample)/62(total in sample) = 45(total marked fish)/x(total population. Next cross-multiply 45 * 62 and 8 * x and set them equal to each other, getting you to the equation 2790 = 8x. Finally, to find x, the population size, divide 2790 by 8 to get x= 348.75.

The nutritional energy content (in Calories) present in 86g of broccoli with 2.6g of protein, 6g of carbohydrates, and 0.3g of f
Nimfa-mama [501]

Answer:

40 Cal

Explanation:

Data provided in the question:

Protein present in the broccoli = 2.6 g

Carbohydrates present in the broccoli = 6 g

Fat present in the broccoli = 0.3 g

Now,

We know,

Energy provided by protein and carbohydrates = 4 Cal / g

and,

Energy provided by Fats = 9 Cal / g

Therefore,

Total nutritional energy content = ∑(Amount × Energy provided)

= ( 2.6  × 4 ) + (6 × 4) + (0.3 × 9)

= 10.4 + 24 + 2.7

= 37.1 Cal    

rounding off the answer to nearest 5 ≈ 40 Cal
