Crabgrass preventers can be categorized under Residual Herbicides simply because they can stay in the soil for a considerable amount of time and control germination for the weeds. It prevents growth by staying on the ground longer.
I'm pretty sure we have the same class. And you got your answers mixed up with the question. But the correct answer is D) states whose economies rely on coal, oil, or gas. Good luck.
Answer and Explanation: The farmer has a pure-breeding line of tomato means the farmer has a tomato with genotype FFrrtt while the other line of tomato has genotype ffRRTT.
The cross between these lines gives a F1 generation of heterozygous full, red and axial or FfRrTt.
With an individual of F1 crosses with another individual of F1, the Punnet Square will be:
FfRrTt x FfRrTt
1) Dividing each characteristics, for simplicity:
F f
F FF Ff
f Ff ff
R r
R RR Rr
r Rr rr
T t
T TT Tt
t Tt tt
Analysing Punnett squares, we notice the line wanted (ffrrTT) will be produced, when an individual of F1 generation cross with another individual with the same generation.
The answer is either a or c
