If one of the waste products of cellular respiration is CO2 by means of exhaling, then do you think the rate of cellular respira
GREYUIT [131]

If one of the waste products of cellular respiration is CO2 by means of exhaling, then the rate of cellular respiration increased.

<h3>What is Cellular respiration?</h3>

This consists of series of reactions which combine the chemical energy from foodstuffs and oxygen to form ATP and other waste products such as carbon dioxide and water.

During this process, the carbon dioxide is transported from the mitochondria out of the cell, to the red blood cells, and to the lungs where they are exhaled.

This therefore depicts that the cellular respiration increased as a result of the carbon dioxide given off via exhalation and thereby makes it the correct choice.

Calculate the mass/volume percent of a NaCl solution in which 140 g of NaCl is dissolved in enough water to give a total volume
Len [333]
Mass per volume percent is simply calculated by getting the ratio of the mass in g of solute and the volume in mL of the solution multiplied by 100 percent. In the problem, we are given all the required values. Calculation is as follows:

%w/v = 140 / 1590 x 100 = 8.81%

Answer:

I believe it is D

Explanation:

since Rutherford's explanation, when he made it in 1911, was that scattering was caused by a hard, dense court to centre of the Adam, which is the nucleus and he used Alpha particles to observe the scattered backwards from a gold foil

The density of water is 1 gm/ml. An object has a mass of 58 grams. What volume must it have in order to float in water?
Keith_Richards [23]

Answer:

58mL

Explanation:

Given parameters:

Density of water  = 1g/mL

Mass of object  = 58g

Unknown:

The volume the object must have to be able to float in water = ?

Solution:

To solve this problem, we know that the object must have density value equal to that of water or less than that of water to be able to float.

We then set its density to that of water;  

   Density  = \frac{mass}{volume}  

      Volume  = \frac{mass}{density}  

So;

      Volume  = \frac{58}{1}   = 58mL
