Protists belong to the group eukaryotes (having their DNA enclosed
inside the nucleus). They are not plants, animals or fungi but they act like
one. They can be in general subgroups such as unicellular algae, protozoa and
molds. They thrive in environments with little sunlight. But they are not
plant-like organisms. The answer is letter B.
Hybrid = having one recessive and one dominant allele
This means that all of the flowers must have the genotype Bb.
Knowing this, let's make a Punnet Square.

As you can see, 3 of these are going to have the dominant trait and 1 is going to have the recessive trait. This corresponds to our 3:1 in our question, meaning that the black seeds must be dominant and the brown ones recessive.
Because they are dominant, the genotype for black seeds could be
BB <em /><em>or</em>
Bb.
Answer:
Hydrogen bond
Explanation: Pretty much just a type chemical bond
It is called a sister chromatid, not a polar body.
