I can’t help you with the first two questions, as I do not have a reference, but I can help you with the last two. Cystic fibrosis is a recessive trait. It is caused when specific sections of both copies of chromosome 8 are deleted, which in other words mean that it is not a sex-linked disorder because it isn’t inherited from the mother and father of the offspring.

No, all mutations are not bad. Only a small amount of mutations cause genetic disorder. Some in fact are good mutations. There is actually one mutation that is found roughly in 10% of Europeans which affects the CCR5 protein and it prevents HIV from entering the cell!

RideAnS [48]

Answer: Those which can adapt and withstand the high acidity levels of water.

The pond slowly becomes more acidic due to release of chemicals from a nearby factory. The chemicals released are acidic and toxic which will cause biomagnification in the pond water. Those organisms which can withstand the high acidic pH of water will survive. Others which can undergo adaptations can also survive.

Potassium has a half-life of 12 hours. What fraction of a 100g sample is left after 48 hours
EastWind [94]

Answer:

After 48 hours amount left = 6.25 g

Explanation:

Given data:

Half life of potassium = 12 hours

Total mass = 100 g

Mass left after 48 hours = ?

Solution:

Number of half lives passed:

Number of half lives = Time elapsed / half life

Number of half lives = 48 hours/ 12 hours

Number of half lives = 4

At time zero = 100 g

At first half life = 100 g/ 2 = 50 g

At 2nd half life = 50 g/2 = 25 g

At 3rd half life = 25 g/2 = 12.5g

At 4th half life = 12.5 g/2 = 6.25 g

What was Mendel's explanation for the fact that 0% of the offspring from this cross were green?
VMariaS [17]
So Mendel got roughly 75% yellow and 25% green in f2. This means that f1 contains all heterozygous genes, as shown below

Y y
Y YY Yy
y Yy yy
Summary: 75% YY or Yy, 25% yy

Which means that green (y) is a recessive phenotype, while yellow (Y) is a dominant phenotype, since plants with heterozygous genotype Yy express the yellow trait.

How does evolution lead to both the diversity and the unity of life?
gogolik [260]
<span>Simple. All of the millions of different life forms (the diversity of life) have come about by natural selection, whereby random mutations in the genes have either succeeded or failed. But all life can be traced back to a common single-celled origin. Thus we have the unity of life where we (possibly) share more than 50 % of our DNA with a crocodile.eg:analogous organs, homologous organs.</span>
