Which of the following is true about pastoralism?

S_A_V [24]

Answer:

The answer is D

Explanation: I live on a farm, seasonal movement; It allows the animals to find new fresh green grass. It also allows the grass (where the animals were currently grazing) to help it grow back so then when the animals come back they will have nice green grass to eat next season. It also allows the people to take care of the land without any animal getting injured.

The equations of the tangent to the curve y=xsinx at the point (pi/2,pi/2) is

never [62]

The first thing you have to realize is that tangent is the slope of a curve on a given point. You can solve for the slope by finding the derivative of the given function. So:

$\frac{d}{dx} xsin(x)$

Next use product rule (I recommend watching videos if you're confused):

$= [sin(x)] + [x*cos(x)]$

Next substitute you x-value (π/2) into your derivative:

$= [sin( \frac{ \pi}{2} )] +[ \frac{\pi}{2}*cos( \frac{\pi}{2})]$
$= 1 + \frac{\pi}{2} *0$
$= 1$

So our slope at π/2 is 1. Next we use our slope-form and substitute our given value and solve for y-intercept (algebra-stuff)

$( \frac{\pi}{2}) = 1( \frac{\pi}{2}) + b$
$b = 0$

So we get our equation:

$y = x$

So our answer is E

Feel free to ask any questions.
Hopes this helps!

(a) Describe the effect on chlorophyll-containing photosystems when the chlorophyll molecules absorb photons of light.

ExtremeBDS [4]

Answer:

Photosynthesis begins in chlorophyll-containing photosystems.

Explanation:

Photosynthesis begins in chlorophyll-containing photosystems when the chlorophyll molecules absorb photons of light. This energy passes through other chlorophyll molecules, towards the reaction center of Photosystem II. The researcher should use plant with normal enzyme as a control with a plant having mutant enzyme. A plant that has multiple photosynthetic pigment has greater fitness as compared to plant that has only one type of photosynthetic pigment because multiple pigments absorb different wavelengths of light that allows the plant to capture the maximum amount of energy from the sun for photosynthesis.
