Which trait will an organism that receives one dominant gene and one recessive gene most

Chemistry

velikii [3]3 years ago

Answer:

The dominant gene - such as brown hair or brown hair

Explanation:

Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked. A person with two dominant or two recessive alleles for a trait is "homozygous." A person with one dominant and one recessive allele for a trait is "heterozygous." Because a boy inherits only one X-chromosome, if there is a recessive gene on that X-chromosome, the gene is expressed.

State the types of change that take place in each of the following
atroni [7]

Answer:

Chemical changes

Explanation:

a)Burning a piece of charcoal - chemical change

b) Heating copper (ii) carbonate strongly - chemical change

c) Heating Zinc oxide strongly - chemical change

The given types of reaction indicates chemical changes. A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes. The process is not easily reversible and hence, it is a permanent procedure.

 Burning of charcoal produces a new kind of produces in the combustion process.

Both heating of copper(ii)carbonate strongly and zinc oxide will lead to a decomposition reaction in which new compounds are formed.

Calculate the percent error in the atomic weight if the mass of a Cu electrode increased by 0.4391 g and 6.238x10-3 moles of Cu
PIT_PIT [208]

Answer:

10.77%

Explanation:

Molar mass of Cu = mass deposited/number of moles of Cu

Molar mass of Cu = 0.4391 g/6.238x10^-3 moles

Molar mass of Cu = 70.391 g/mol

%error = 70.391 g/mol - 63.546 g/mol/63.546 g/mol × 100

%error = 10.77%

Penicillin N is an antibacterial agent that contains 8.92% sulphur by mass.Which could be the molar mass of Penicillin N? a)256g
scoundrel [369]
Answer : Option B) 360 g/mol

Explanation : 
The antibacterial agent Penicillin N contains 8.92% of sulfur by mass. So we have to calculate the molar mass of penicillin N will be as 

i) 256 X 0.0892 = 22.83 g/mol this cannot be the answer as it doesn't shows any sign of sulfur being present even in 1 mole.

ii) 360 X 0.0892 = 32.112 g/mol This is the closest to the molar mass of sulfur which is 32.06 g/mol; this means it contains 1 mole of sulfur.

iii) 390 X 0.0892 = 34.78 g/mol this also fails to prove the answer as correct.

iv) 743 X 0.0892 = 66.27 g/mol This is not even falling in the range of sulfur mole.

Hence we can confirm that the answer is Option B

Write a balanced half-reaction describing the oxidation of aqueous gold(i) cations to aqueous gold(iii) cations.
bezimeni [28]
<span>Balanced half-reaction: Au</span>⁺<span>(aq) </span>→ <span> Au</span>³⁺(aq) + 2e⁻.
Oxidation reaction is increasing of oxidation number of element, because element or ion lost electrons in chemical reaction.
Gold lost two electrons and change oxidation number from +1 to +3.
Reduction is lowering oxidation number because element gain electrons.
