In certain plants, tall is dominant to short. if a heterozygous plant is crossed with a homozygous tall plant, what is the probability that the offspring will be short?
a) 1
b) 1/2
c) 1/4
d) 1/6
e) 0

The answer is E) 0.

If:
A - dominant allele,
a - recessive allele,

then:
AA - dominant homozygous (tall),
aa - recessive homozygous (short),
Aa - heterozygous (tall).

A heterozygous plant (Aa) is crossed with a homozygous tall plant (AA):

Parental generation:         Aa     x    AA
F1 generation:           AA     AA     Aa     Aa

All of the offspring is tall (AA or Aa), since tall is dominant to short.
There is no chance for offspring to be short (aa).

That is true tge cactus as a structural adaptation to its envirinment has it leaves reduced to spines. but this doesnt mean it cant produce food it produces food because of the presence of chlorophyll in its stem

Ibelieve its b but u might have to
