Answer:

Homeostasis is the cells response to its environment.

Explanation:

Homeostasis is the cell response to its environment to maintain its steady state between internal conditions and outer environment. Here cell maintains cell temperature, fluid balance, sugar balance etc through it ( keep it in a pre-decided range known as homeostatic range) Ex:- when their is cold outside we start shivering and get energy to maintain our body temperature.

Answer: The correct answer is : A, B, C, D. All statements are correct.

Explanation: This case is called non-competitive inhibition. As a result of the inhibition of the enzyme, there will eventually be less substrate that becomes the final product and this route will be closed. Enzyme 1 has two binding sites.

Practice Exercises Name: : Billy-Joe stands on the Talahatchee Bridge kicking stones into the water below a) If Billy-Joe kicks

babymother [125]

Answer:

a) The answer is 11,7m

b) The time it takes to fall will be shorter

Explanation:

We will use the next semi-parabolic movement equations

$H=Hi+Viy*t+1/2*g*t$

$X=Xi+Vx*t$

Where g(gravity acceleration)=9,81m/s^2

Also Xi, Hi and Viy are zero, as the stones Billy-Jones is kicking stay still before he moves them, so we take that point as the reference point

The first we must do is to find how much time the stones take to fall, this way:

$t=(5.40m)/(3.50m/s)$

Then t=1,54s

After that we need to replace t to find H, this way

$H=(1/2)*(9,81m/s^2)*(1,54s)^2$

Then H=11,7m

b) The stones will fall faster as the stones will be kicked harder, it will cause the stones move faster, it means, more horizontal velocity. In order to see it better we could assume the actual velocity is two times more than it is, so it will give us half of the time, this way:

$t=(5,40m)/(2*3,50m/s)$
