The greenhouse effect is the trapping of the sun's warmth in a planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun
Chlorophyll is the main pigment in this case. Without it, it basically would not exist.
Answer:

Explanation:
There is a proper mechanism of controlling the levels of various kinds of hormones and chemicals in our body called as positive feedback and negative feedback.
In a very simple language you can understand it as whenever there is a release of a particular hormone or chemical inside the body in very huge amount then the negative feedback of the body is activated the production of that particular hormone or chemical is stopped and vice -versa for negative feedback.
Explanation:positive feedback and negative both the feedback mechanism are achieved to maintain the proper homeostasis.
Example: release of clotting factor after blood loss is a positive feedback and a hormone is released and then suddenly there is a increase in hormone b, then the amount of hormone a will decrease this is a negative feedback.
Answer:
The arc is 6.4 units long.
Explanation:
For a circle of radius R, the circumference is given by:
C = 2*pi*R
If we have a section of this circle defined by an angle θ (such that this section makes an arc), the length of that arc is:
A = (θ/360°)*2*pi*R
and 2*pi*R is the circumference, then we can write the length of the arc as:
A = (θ/360°)*C
qsIn this case, we know that the circumference is equal to 8 units, and the arc has an angle of 288°
Then the length of that arc is:
A = (288°/360°)*C = (288°/360°)*8 = 6.4
The arc is 6.4 units long.
