Answer:
None of the birds have the same niche.
Explanation:
They all have different niches because of the food they ate. Over time, they were gentically changing to adapt to their own food.
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:
option C
Explanation:
Plants may serve as starting point when observing the carbon cycle. they undergo a process called photosynthesis that enables them to absorb and utilize carbon dioxide from the atmosphere and combine it with water. in the presence of the energy of the Sun absorbed by chlorophyll in plants, they are able to synthesize sugars and oxygen molecules. They play a huge in keeping the air clean with the carbon becoming a part of the plant. Plants and other organisms that die and become buried may be converted into fossil fuels made of carbon like coal and oil over millions of years. when these are then burnt by humans, most carbon then return to the atmosphere as carbondioxide.
