Tju [1.3M]

Answer:

The answer is 17190 years

Explanation:

Original amount was 5730. To become 1/8 of the original amount, three (3)  half life periods will demand because after first half life the amount will become 1/2 and after second half life, amount become 1/2 again (1/2 x 1/2 = 1/4).  Third half life, the amount become half 1/2 again (1/2 x 1/2 x 1/2 = 1/8).

For the 3 half life periods we have original amount x numbers of half life periods = 5730 years x 3   =  17190 years

nasty-shy [4]

Answer:

Principles by Mendel

Explanation:

The heritage principles of Gregor Mendel are at the core of modern genetic engineering. Mendel has created three heritage principles by conducting experiments with pea plant breeding, which described the passing on of genetic characteristics before anyone thought that genes did exist.Mendel referred to this components as "elementen" and suggested that, throughout sexual reproduction, each parent contributes a form of elementary elementen to the resultant offspring. This blend of parental elementen then defined what type of characteristic was noticeable in the descendants.

Genetic concepts are laws or guidelines regulating the biological heredity process, the transition of parents' to children's attributes by information that is biochemically transmitted by DNA, to gene units.

If the mass of a material is 92 grams and the volume of the material is 25 cm3, what would the density of the material be?
olya-2409 [2.1K]
<h3><u>Answer;</u> </h3>

= 3.68 g/cm³

<h3><u>Explanation;</u></h3>

Density is given by dividing the mass of a substance by its volume.

Thus; Density = mass/ volume

In this case; mass = 92 g and Volume = 25 cm³

Therefore;

Density = 92 g/ 25 cm³

             <u>= 3.68 g/cm³</u>
