neonofarm [45]

Answer:

<em>No, these exceptions do not discredit natural selection.</em>

Explanation:

Natural selection tends to favour those organisms which are better adapted to live in an environment. But it does not completely remove the other organisms from the world that are less adapted to live in an environment. Usually, the number of these organisms that are not favoured by natural selection is very less as compared to the number of organisms which are favoured by natural selection. As we see, the number of albino animals is far lesser as compared to their wild-type animals.

Eq-4 what do you do when you see another vessels red and white lights
REY [17]

Answer;

When only white and red lights are visible, you are approaching the port side of a powerboat and thus you should give way to your starboard side.

Explanation;

-The red and green lights are called sidelights (or combination lights) because they are visible to another vessel approaching from the side or head-on. The red light indicates a vessel's port (left) side; the green indicates a vessel's starboard (right) side.

-When only a white light is visible, one may be overtaking another vessel. Give way to either side. Additionally, when only a red light is visible, you are approaching the port side of a sailboat.

Ainsley lives in a town 360 miles directly north of Orlando. One Saturday, she takes the train from her town to Orlando. The tra
MakcuM [25]
Take note that the total distance that needs to be traveled is 360 miles. The train is moving at 60mph and 2.5 hours have passed. To get the remaining distance, first you need to solve for the distance traveled already. 

Distance is equal to the velocity times the time travelling or:

d = vt

So considering the given we can get the distance traveled in 2.5 hours. 

d = vt
d = (60mph)(2.5h)
d = 150miles

So far, Ainsley traveled 150 miles. If her town is 360 miles away, you can get the remaining by subtracting the distance already traveled from the total distance. 

360 miles - 150 miles = 210 miles. 

Now if you want to put that into a single equation you can do that by combining all the equations together.

d = 360 miles - (vt).
d = 360 miles - (60mph)(2.5 h)
d = 360 miles - 150 miles
d = 210 miles

Very low concentrations of detergent make membranes leaky to small molecules and ions without damaging proteins. In isolated mit
BigorU [14]

No, because with a leaky membrane, the proton gradient cannot be maintained

<h3><u>Explanation</u>:</h3>

The cell membrane is composed of a protein lipid bilayer. The detergent is very efficient to clean out portions of lipid from the protein part, thus disrupting the cell membrane. In presence of low concentration of detergent, the small portions of lipid are taken out, leaving the cell membrane structure intact, but with smaller pores which can lead to leakage of several smaller substances from inside.

So these leaky membranes don't allow the gradient of proton to build up. Thus ATP cannot be produced. So the cell cannot respire with detergent present.
