Mention many ways to change how we use water, Which way do you think is the best and explain why.
sergij07 [2.7K]

Answer:

The easiest way to monitor the usage is to manage the water flowing into the home. (If you have a slow flow in your home now, you have much more incentive to watch your use!) - Take baths that consume ten times less water instead of taking a bath.

Explanation:

Ways to save the water:

  • Switch off the tap while your teeth are cleaned
  • Insert your toilet cistern displacement unit to minimize the amount of water that is used with each flush
  • Get a shorter tub. Short shower.
  • Always use the laundry and dishwasher for maximum loads.
  • Remove a drop tap.
  • Build a drainage pipe with a water butt and water the plants
  • Water the lawn instead of a pipe for watering.

What is the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells at night w
lions [1.4K]

Answer:

C. +23.1 kJ/mol

Explanation:

the formula to use to calculate the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells is:

ΔGt = RTIn  \frac{C_{2} }{C_1}   + ZFΔV

let's list the values of the data we are being given in the question to make it easier when solving it.

Z= 1

F= 96500C (faraday's constant)

ΔV= 160mV = 0.160V

R= 8.314( constant)

T= 15ºC ( converting our degree Celsius into kelvin, we will have 273.15k+ 15 = 288.15K)

∴ T= 288.15K

Putting it all together in the formula, we have:

ΔGt = 8.314 × 288.15 × 2.303 log \frac{C_{2} }{C_1}  + 1  × 96500 × 0.160

ΔGt = 5517.25   [ -(log(H^{+}_{out} ) + log(H^{+}_{in} )_{in}  +15440

ΔGt  = 5517.25 (pH_{out} - pH_{in}  +15440

Given that the pH  differential gradient  across the membrane is 1.4pH units. It implies that;

ΔGt  = 5517.25 × 1.4 + 15440

=  7724.15 +15440

= 23164.15 Joules/moles

= +23.1 KJ/mole

Which defines background extinction?
victus00 [196]

Answer:

<em>The correct option is D) the natural extinction rate</em>

Explanation:

Extinction can be described as a process due to which species get removed from the world.

Background extinction can be described as the standard rate of extinction of organisms of a species due to ecological or environmental factors. It is a low-level type of extinction which occurs over a long period of time. It can be described as the natural extinction rate of individual organisms. Hence, option D best describes the natural phenomenon of background extinction.

Fatty acid synthesis can be divided into 3 stages: Stage 1. Export of acetyl CoA from the mitochondria, Stage 2: Synthesis of ma
saveliy_v [14]

Answer:

The third stage in the synthesis of fatty acids is the synthesis of palmitic acid (letter e)

Explanation:

The synthesis of fatty acids takes place in the cytoplasm of the cell. The first step is the transport of acetyl-CoA to the cytoplasm. This came in the form of citrate usually from the pyruvate generated in the glycolysis from the mitochondria. The citrate is enzymatically transformed into acetyl-CoA.

Once the acetyl-CoA is in the cytoplasm, this is transformed into malonyl-CoA. This molecule will be the donor of two carbons in the synthesis of fatty acids.

In the final step takes place a cyclic process of reactions (condensation, reduction, hydration and second reduction) to synthesize the palmitic acid ( 16 carbons) by the fatty acid synthase.
