Answer:

The small number behind each element symbol designates the number of atoms of each element in a chemical formula. If there is no number, it is assumed there is only one of those elements. A large number in front of a compound designates how many units there are of that compound.

Why is it impossible for male calico cats to exist
Kisachek [45]

Answer:

genetics

Explanation:

calico cats must also inherit a gene unrelated to the X and Y chromosomes that codes for white fur. Because male cats have one X chromosome with code for black or orange and one Y chromosome with no color genes, they cannot technically be calico. About one in every 3,000 calico cats is born a male, and, unfortunately, don't live as long as female calicos due to their genetic abnormalities. XXY Syndrome renders male calicos sterile and can be the root cause of many other health problems

solniwko [45]

Answer:

<h2>Proteins even make up most of your hair. ... While a structure such as a nucleus is only found in eukaryotes, every cell needs ribosomes to manufacture proteins. Since there are no membrane-bound organelles in prokaryotes, the ribosomes float free in the cytosol. Ribosomes are found in many places around a eukaryotic cell.</h2>

In a population of 100 four-o'clock flowers there are 40 red-flowered plants (CRCR), 38 pink-flowered plants (CRCW), and 22 whit
miss Akunina [59]

Answer:

Frequency of CW allele in the population= 0.41

Explanation:

A diploid organism has two alleles for each gene. So, a population of 100 plants will have total 100 x 2 = 200 alleles.

The each of the white colored plants have two copies of CW alleles and each pink flowered plant have only one CW allele.

Frequency of CW allele in the population = total number of white flowered plants x 2 + total number of pink colored plants / total population size x 2.

Frequency of CW allele in the population= 22 x 2 + 38 / 100 x 2 = 82 /200 = 0.41
