The atmosphere has many functions, such as _____.
BaLLatris [955]

Answer:

Atmosphere refers to the thin blanket of air that surrounds the earth.

It serves many important functions such as:

  • It contains a mixture of gases that are essential for the existence of life on earth. For example, carbon dioxide is essential for photosynthesis and oxygen is essential for cellular respiration.
  • It also serves as the reservoir of water in the form of water vapor. Thus, it forms an important constituent for the water cycle.
  • It maintains the temperature of the earth. Through the greenhouse effect, it maintains the temperature of the earth in limited ranges.
  • It protects the earth from harmful rays of the sun. For example, ozone inhibits the entry of most of the UV rays of the sun into the earth environment.

A sand storage tank used by the highway department for winter storms is leaking. As the sand leaks out, it forms a conical pile.
harina [27]

Answer:

Rate of change of volume of the pile  = 54\pi

Explanation:

Given -

Rate of increase of the base of the pile = 0.75 inches per minute

Height of the pile = 2 * the radius of the base

Let "h"  be the height of the pile and "r" be the radius of the base.

Then h = 2* r

Radius "r" = 6 inches

Rate of change of radius i.e

\frac{dr}{dt} = 0.75

Volume of conical pile

\frac{\pi }{3} * r^2 * h\\= \frac{\pi }{3} * r^2 * 2 * r\\= \frac{\pi }{3} *2* r^3

Change in volume of conical pile

\frac{dV}{dt} =  \frac{dr}{dt}  * \frac{6* \pi * r^2 }{3}

Substituting the value of rate of change of radius, we get -

\frac{dV}{dt}  = 2 * \pi * (6^2) * (0.75)\\\frac{dV}{dt}  = 54 \pi

Rate of change of volume of the pile  = 54\pi

Can amoeba have offspring with different genes and traits
stepan [7]

Here is your answer

No

______________________________

REASON:

Amoeba reproduces by the process of binary fusion which is an asexual mode of reproduction.

Since, in asexual method mitosis cell division takes place, same DNA material is transferred to the offsprings so no new traits and genes can be found in offsprings.

However in some case due to genetic drift or mutation, slight variations can be found in progeny.

But this is very exceptional.
