The best answer is A.
Mitochondria are small organelles found floating free in the cytoplasm of both animal and plant cells. They consist of two membranes, an outer and inner membrane which has numerous folds creating layered structures called cristae.Inside the mitochondria, there is found fluid called the matrix
Mitochondria are the powerhouse of cells. Many of the reactions in cellular respiration that take place in the cell occur in mitochondria and thus these organelles are key in the production of energy .
I'm just guessing since this is my prediction. Either B. or D. I dont know about C. and it is definitely not A. since the lumber companies are only taking down some trees instead of all of them.
Answer:
The first line of defence (or outside defence system) includes physical and chemical barriers that are always ready and prepared to defend the body from infection. These include your skin, tears, mucus, cilia, stomach acid, urine flow, 'friendly' bacteria and white blood cells called neutrophils.

Answer:
From your list of answers it would be to collect rock samples from the moon.
Explanation:
The cell interior would experience higher than normal Na⁺ concentrations and lower than normal K⁺ concentrations.
<h3><u>Explanation</u>:</h3>
The membranes that contain high concentration of sodium potassium ATPase pumps are generally the excitable membranes. These are found in muscles and in neurons.
In normal scenario, the de polarised membrane has higher potassium concentration inside and higher sodium concentration outside it. Now as an impulse comes, the sodium channels open which creates sodium influx and then potassium channels open which let's potassium efflux. Then after the conduction of impulse is over, the membrane regains its de polarised state by the sodium potassium ATPase pumps which transfers three potassium outside the cell and two potassium inside the cell in exchange of an ATP.
Now if the ATP is non hydrolyzable, then the pump won't occur. This will lead to greater sodium inside the cell and greater potassium outside the cell but the change difference will be nil on both sides.
