Hope the helped, you can read this and make a educated guess based off information given.
All cells have cell membranes<span>, and the </span>membranes<span> are flexible. So </span>animal cells<span> can</span>have<span> various shapes, but </span>plant cells<span> only </span>have<span> the shapes of their </span>cell walls<span>. That's nice for </span>plants<span>, because it gives them the ability to grow up and out, where they can get lots of sunlight for making their food.</span>
the Speed = Wavelength*Frequency. For example 22*5 = 110 which means the answer would be S = 110mm/s.
Are you sure this question is correct?
If you made a mistake and the question is 20mm/s and 5 freq instead of 22 and 5. Then your answer would be A. 100 mm/s.
Hope this helps! Please mark as brainliest if it did.
Answer:
<em>The transport protein would best be described as the activity of the sodium potassium pump. However, none of the alternatives are correct. </em>
Explanation:
<em>Letter A: stopping the activity of the sodium potassium pump is incorrect because, it is the only mechanism of transport our organism has to move proteins into the cell. So, if we stop it or inhibit the sodium potassium pump, we will cause damage into the heart and intestine cells.</em>
<em>Letter B: Increasing the concentration of glucose outside of the cell is incorrect because, on normal conditions the glucose tends to outflow the cell, so the correct answer would be reduce the concentration of glucose outside of the cell, so that the amount of the glucose remain inside of the cell.</em>
Letter C: lowering the energy of activation has nothing to do with this process at all.
Letter D: Increasing the number of digestive enzymes does not have anything to do with this process neither.
The letter A could be the write answer, if could delete the word stopping.
a) It's necessary to distinguish foreign cells and proteins because they could possibly be viruses since viruses have the function of a cell and coat of a protein.
b) Sickness could occur if the recognition system fails
