Mendel crossed purebred purple-flowered plants with purebred white-flowered plants, and all of the resulting offspring produced purple flowers. The offspring are all , and the allele for purple flowers is .

A. heterozygotes, recessive
B. heterozygotes, dominant
C. homozygotes, recessive
D. homozygotes, dominant

B.  Heterozygotes, dominant

Explanation:

As given pure bred purple plant is crossed with pure bred  white flower, their resulting flowers are all purple, it shows that purple is dominant over white.

So let purple as PP and white as pp

cross between PP and pp

PP×pp ; their gametes are Parent-1: P , parent -2, p

Offspring are: Pp, Pp, Pp, Pp

Here all offspring are heterozygous and the allele for purple color is dominant over white color.

This is what i found on google“ the monomers combine with each other via covalent bonds to form larger molecules known as polymers. in doing so, monomers release water molecules as byproducts. this type of reaction is known as dehydration synthesis, which means “to put together while losing water. in the process, a water molecule is formed.” i hope this you

Hydrosphere is the correct answer
