For the answer to the question above. I believe the answer to your question is <span>"75/100 = 3/4" is the dilution needed for a 75ml of diluent added to 25ml of bacterial suspension</span>.
I hope that my answer helped you. Have a nice day!

Answer:

The dilution is 1/4.

Explanation:

Dilution is the process of decreasing the concentration of any substance by adding the diluent into it. If we want to prepare 1:5 dilution of bacterial culture in 10 ml than 2 ml of bacterial culture should be added in 8 ml of diluent making total solution 10 ml.

So the dilution comes 1:5 after dividing 2 ml bacterial suspension with 10 ml of total solution(2/10=1:5). Therefore similarly addition of 75ml of diluent in 25 ml bacterial culture makes total 100 ml and in that 100 ml, 25 ml is bacterial suspension.

So by dividing 25 ml bacterial suspension by 100 ml of total solution we will get 1/4 ratio. Therefore the correct answer is 1/4.

describe two alternative photosynthesis pathways found in plants suggest how how these adaptions might help plants
klio [65]

a. Sugar cane, corn, carbgrass which are identified as C4 Plants allow fixation of carbon dioxide into four carbon compounds. This happens during the  hottest time of the day - their so-called stomata gets partially closed. C4 plants have been identified to lose only half of the water that C3 plants lose when they produce the similar amount of carbs.

<span>b.CAM PATHWAY - Plants such as pineapples and cactus have different approach to adapting heat. Carbon is fixed through a cam pathway. They use it to open their stomata at night and close it in the morning.</span>

Describe the three major sources of energy taht power earth's environmental systems
MArishka [77]
There are two major sources of energy that power the earth's environmental systems, these are SUN AND THE EARTH'S INTERIOR HEAT.
The heat energy from the sun is the one responsible for processing all the external processes that occur in the atmosphere, hydrosphere and on the earth surface.
The energy from the earth's interior is the one that is respondsible for powering the internal processes that produce earthquakes, volcanoes eruptions and mountain formation.

Increased water volume causes the hydrostatic pressure in plasma to increase and the osmotic pressure to decrease; as a result,
lapo4ka [179]

When there is an increase in water volume in plasma, it causes the hydrostatic pressure in plasma to increase and the osmotic pressure to decrease and as a result, water will move out of plasma.

<h3>How does increased water volume affect hydrostatic pressure in plasma</h3>

When water volume in plasma increases, the hydrostatic pressure will increase.

Increase in water volume will result in a decrease in the osmotic pressure of plasma due to dilution of the solutes in plasma.

Therefore, to maintain homeostasis, water will move out of the plasma by simple diffusion and osmosis.

Therefore, increased water volume causes the hydrostatic pressure in plasma to increase and the osmotic pressure to decrease and as a result, water will move out of plasma.
