Answer:
<h2>D) 610:190, round seeds:wrinkled seeds</h2>
Explanation:
Let round seed as R and wrinkled seed as r.
So the round is dominant (R) over wrinkled(r).
Hence , round is dominant and wrinkled is recessive rr.
Now cross between pure round (RR) and pure wrinkled (rr).
RR× rr
F1 offspring are: Rr ( all)
Now cross between F1 offspring;
Rr × Rr
F2 are= RR, Rr, Rr and rr
RR and Rr = round
rr= wrinkled.
round to wrinkle ratio is= 3:1
So, 610:190; round seeds:wrinkled seeds is the expected result in the F2 progeny.
Answer:
The correct answer is the alarm reaction.
Explanation:
The alarm reaction or stage is the initial stage of the body's response to a stressful situation or stimuli, due to acquired physiological changes, such as high heart rate and increase in hormones activity.
In simple words, it is a reaction that body adapts in tough or fight or flight situation by pumping blood from the heart to arms and legs to fight or flight.
Thus, the correct answer is alarm reaction.
Light reactions happens in the thylakoid membrane, and the calvin cycle happens in the stroma. What happens to water molecules in the light reactions? It's broken apart and the electrons go to photosystem II. ... Then they pump H+ into the thylakoids, and are used to make ATP out of ADP.
The right option is; nucleus
Nucleus is the organelle that controls information in the cell.
Nucleus is the most prominent membrane bound organelle that is situated within all eukaryotic cells. The nucleus controls all the activities of the cell and it contain most of the cell's genetic material (DNA). The nucleus is surrounded by a double membrane (nuclear envelope) which maintains the shape of the nucleus, and keeps the nucleus contents from the cytoplasm.
