Answer;

-Elements are composed of atoms

Explanation;

-A chemical element consists of atoms with a specific number of protons in the nucleus; this number is called the atomic number. The atoms of an element may differ in the number of neutrons; atoms with different neutron numbers are said to be different isotopes of the element.

-Elements are represented by a chemical symbol, with the atomic number and mass number sometimes affixed.

Which of the following combinations of coefficients correctly balances this chemical equation: 2H2S (g) + __O2 (g) __CO2 (g) + 2
frez [133]
In chemistry for an chemical equation to be complete it has to be balanced using appropriate coefficients and state symbols such similar atoms are equal in both sides of the equation. The reaction between hydrogen sulphide and oxygen gas yields sulphur iv oxide and water as indicated by equation.
 2H2S (g) + 3O2 (g) = 2SO2(g)+ 2H2O(l).
therefore the correct answer is 2,3,2,2

Which of these defines the term PHENOTYPE (with reference to a gene's alleles)?
spayn [35]

Answer:

Phenotype is : The actual appearance or characteristics of an individual organism (i.e the effect of allele combination ).

Explanation:

We come across differences shown by   individuals of same  species or we can say dis-similarity shown by offspring when compared to his/her parents .

When we cross parental generation , the gamete formation occur in accordance with Law of Segregation and then we get to see different combination of gametes that give rise to offspring with contrasting characters (In accordance with Law of independent assortment ).

After crossing we make conclusions by calculating the phenotypic and genotypic ratio of the cross .

Phenotype : It refers to physical expression of an organism or  The actual appearance or characteristics of an individual organism (i.e the effect of allele combination ).

Phenotypic ratio of Monohybrid cross is always 3:1 .

Genotype : Refers to genetic constitution of an organism .

Genotypic ratio of Monohybrid cross is always 1:2:1 .
