You are studying the population growth of a species of fish. Assuming unlimited resources, no predators, and a constant per capi
ArbitrLikvidat [17]

The projected population size in 2030 will be : ≈ 44159

First step : determine the population growth rate

Gr = change in population / time

    = ( 1500 - 1100 ) / 1 year

    = 400 = 36%

<h3>Determine the projected population size </h3>

applying Malthus's population projection.

Pp = P₁ ( 1 + r )ⁿ

where ; P₁ = 1500, r = 0.36 , n = ( 2030 - 2019 ) = 11 years

Pp = 1500 ( 1 + 0.36 )¹¹

    = 1500 ( 29.439 )

    = 44158.5  ≈ 44159

Hence we can conclude that the projected population size as at 2030 is 44159

What is the molarity of a solution that contains 5.80 grams of nickel (ii) nitrate in 500. ml?
Rus_ich [418]

Answer:- 0.0634 M

Explanation:

molarity is defined as the number of moles of solute in 1 L of solution

molar mass of Ni(NO₃)₂ - 182.7 g/mol

number of moles of Ni(NO₃)₂ - 5.80 g/ 182.7 g/mol = 0.0317 mol

number of moles in 500 mL - 0.0317 mol

therefore number of moles in 1000 mL - 0.0317 mol / 500 mL x 1000 mL/L

molarity of the solution is - 0.0634 M

sammy [17]

When the nurse is reinforcing medication, the statement that she has to tell him should be apply the patch every morning and leave there for period of  12 to 14 hours, then remove it in the evening.

<h3>What is angina?</h3>

This is the condition that humans may have that would include very painful chest problems. The pain is usually severe. This pain would spread to the shoulder and other body parts. The reason would be poor circulation of blood.

<h3>What does it mean to reinforce medication?</h3>

This has to do with all of the ways that the nurse is going to ensure that there is medication compliance. It is necessary for people with health issues to adhere to taking their medications.

This would help to ensure that there is team based care that would last for only a period of time. It would help the patient to get better faster.

Hence the statement that has to be included when reinforcing medication would be: apply the patch every morning and leave there for period of  12 to 14 hours, then remove it in the evening.
