The correct answer is "C".
Onion cell is a plant cell and human cheek cell is an animal cell. Hence, onion cell has a cell wall<span> but not in human cheek cells because animal cells do not have cell wall. Both cells have single nucleus. Since, human cheek cell is an animal cell, chloroplasts are cannot be seen in the human cheek cells.</span>
Answer:
Crustaceans and Molluscs play an important role in the oceanic carbon sink.
Explanation:
Carbon sinks can serve to partially offset greenhouse gas emissions. Forests and oceans are both large carbon sinks. Algae is pressurized to bottom of the ocean by long term sequestration. Algae then falls to the bottom of the ocean and TRANSFORMS to fossil fuels.
- CO2 is not combustible.
- creates carbonic acid in the oceans.
- Reduces seawater pH, carbonate ion concentration, and thus calcium carbonate (needed for shells for marine creatures, contributes to BOTTOM-UP EFFECT)

If two Bb guinea pigs cross, there are four possible outcomes:
- both pass the B: the son is BB
- one of the pass the B and the other pass the b: the son is Bb
- both pass the b: the son is bb
Since B (being black) is dominant, the son will be black in both BB and Bb cases. In order for a son to be brown, he must be a pure bb specimen.
So, if all of the offspring are black, it means that all four guinea pigs are either BB or Bb, which in turn means that at least one of the parents passed the B gene.
When fixed carbon leaves the Calvin cycle or light dependent reactions, it will become the molecule G3P, which is then combined to make glucose. The rest of the carbon is recycled to replace RUBP.
Answer:
Triangles FGH and UVW
Explanation:
For two triangles to be congruent, they must be the same size and shape. We know these two triangles are the same shape because of the hash marks being in the same places and representing the same values on each one.
