Answer: The correct answer is -

Recessive and dominant alleles are the two different forms of a gene that are also known as gene variants.

A dominant allele (represented by capital letter allele such as T for tall pea plant) is the one that masks the expression of a recessive allele.

It shows its phenotype even when a single copy of it is present in the genotype (such as in case of Tt, which represents Tall plant).

On the contrary, a recessive allele (represented by small letter allele such as 't' for dwarf) is the one that only shows its phenotype when present in a homozygous recessive form (like tt for dwarf). This is because it is masked when present with a dominant allele.

You should say NO in a firm voice because they will know that you are positive in your decision and hopefully they will leave you alone. If they don't then that is when you start taking other steps in order to avoid peer pressure. I hope this helps!

A substance with a ph of 5 is called
ddd [48]

Answer:

A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.

Please said thanks
