Answer:

1. A hydrogen fuel cell is more efficient than a combustion reaction because very little of the released energy is released as HEAT.

We need more energy emit as light and less heat. Lesser the heat more the efficiency.

2. when used at home a fuel-cell illuminates the need for an electrical grid because the cell is portable.

As said, it is portable.

Which statement correctly compares mass and weight?
hram777 [196]

Answer:

D. Weight varies with location, but mass does not vary

Explanation:

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, the weight of an object is given by the formula;

Weight = mg

Where;

  • m is the mass of the object.
  • g is the acceleration due to gravity.

Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.

Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).

<em>Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.</em>

Which pair of biogeographic regions is the most likely to have species that show convergent evolution?.
Alexeev081 [22]

The biogeographic regions that are the most likely to have species that show convergent evolution are Nearctic and Palearctic.

<h3>What are Nearctic and Palearctic?</h3>

The Nearctic and Palearctic are two of the eight (8) biogeographic regions present on the Earth planet.

Palearctic represents (in turn) the most widely extended biogeographic region present on the Earth planet.

Biogeographic regions are specific areas consisting of particular biological (biotic components) features.

During discharge patient teaching, the nurse reviews prescriptions with a patient. Which statement is correct about refills for
melamori03 [73]

Answer:  is <em>c. </em><em><u>The patient may have no more than 5 refills in a 6-month period</u></em>.

Explanation:  Schedule C-III medications will not be refilled more than five times in 6 months period of time. Schedule 3 catogory of drugs may contain, valium, tranquillisers, anabolic steroids, testosterone, Tylenol, codeine and Ketamine. The reason behind why patient should not have more refills in a 6 month period of time is because by consuming these drugs patient may experience mild physical dependence or very high physiological dependence. Patient may experience addition (mild to high) while taking schedule C-III drugs. Although schedule C-III drugs are less abusive then schedule 1 and schedule 2 drugs. Schedule 3 drugs are declared as sightly dangerous.

CAPACITY..

Limiting factors determine carrying capacity. The availability of abiotic factors (such as water, oxygen, and space) and biotic factors (such as food) dictates how many organisms can live in an ecosystem. Carrying capacity is also impacted by the availability of decomposers.

BIODIVERSITY...

While food and water supply, habitat space, and competition with other species are some of the limiting factors affecting the carrying capacity of a given environment, in human populations, other variables such as sanitation, diseases, and medical care are also at play.
