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.
Answer:
5 moles of Argon is present in the mixture.
Explanation:
Total pressure of the gaseous mixture = 4 atm
Total number of moles = 16
Partial pressure of Ne = 2.75 atm
By Dalton's law of partial pressure, the total pressure of gaseous mixture is the sum of partial pressures of individual gases which are non-reactive.
Hence:
Also :
Partial pressure = mole fraction*total pressure
∴Number of moles of Argon = 5
Answer:
D.
Explanation:
To convert from grams of a substance to moles of a substance, you use molar mass as a conversion factor. Sodium's molar mass is 22.99 grams per mole. To cancel out grams, you need to place grams on the bottom and moles on the top.
Answer:
most endothermic reactions
Explanation:
In endothermic reactions, the entropy of the environment decreases.
The entropy is the measure of the disorder of a specific system.
An endothermic reaction is every chemical reaction in which energy is absorbed.
In a comparison of an endodermic reaction in which energy is released in light or heat form.
