Pure chlorine is an example of an element.

An element is a chemical substance that cannot be broken down into simpler components in a chemical reaction or by any chemical means, and is made up of atoms that all have the same number of protons. Pure chlorine is an example of an element because it contains only one kind of an atom. Chlorine is a toxic, green, gaseous chemical element. Chlorine is a halogen, has an atomic number of 17, symbol Cl and is found in group 17 in the periodic table. Chlorine is highly reactive and a strong oxidizing and disinfecting agent.

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 $= 54\pi$

You cross two red griffins with blue eyes and produce offspring that are: red with blue eyes, red with green eyes, white with bl

sergejj [24]

Answer:

The reason for the offspring to present these genotypes is that during the formation of the gametes, the alleles separate and are inherited independently, therefore they can generate several different phenotypic combinations.

Explanation:

In order for an offspring to present very different phenotypes, as shown in the question above, it is necessary that the two red griffins with blue eyes that were crossed are heterozygous. Thus it will be possible for the offspring to present a wide variety of phenotype, according to Mendel's second law.

Mendel's second law is called the Law of segregation. This law explains that the alleles (which determine the characteristics of individuals) are separated in the formation of gametes and inherited by the offspring of a cross independently, and can generate different combinations of phenotypes, when the parents of a cross are heterozygous.
