Answer:

The correct answer is - 5L.

Explanation:

From the ideal gas equation -

pv=nRT

p = pressure

v =volume

Here nRT is constant so

P would be inversely proportioned to v

So, p1/p2 = v2/v1

Putting values:

2/4(2) = v2/20 (p2 = 4 times of P1)

2/8 = v2/20

V2 = 5

Thus, the correct volume at new pressure would be - 5 L.

In rabbits, B represents the allele for black coat and b represents the allele for white coat. Black is dominant over white. If
o-na [289]

Answer:

A rabbit with Bb genotype will be black coated phenotypically

Explanation:

The question involves a single gene coding for coat color in rabbits. According to the question, the allele for black coat (B) is dominant over the allele for white coat (b). This means that black coat allele (B) will mask the phenotypic expression of the white coat allele (b) in a heterozygous state.

A rabbit with genotype, Bb is said to be heterozygous because it possesses the combination of the two different alleles (dominant and recessive). Since, the 'B' allele (black) is dominant, it will mask the expression of the 'b' allele (white). Hence, the rabbit will phenotypically appear black coated.

Why are most anions basic in H2O? Give formulas of four anions that are not basic.
AVprozaik [17]

Answer:

The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.
