Answer:
10 B and 11 C thats what I got
I believe the answer is B, primary active transport. Root hair cells in plant use active transport to absorb mineral ions such as nitrates from the soil. The concentrations of minerals in the soil are lower in the soil than in within the root hair cell, therefore the transport will be against the concentration gradient which does not favor diffusion, therefore the pant has to use active transport.
Generally, the sun observes a solar cycle of eleven years. In this cycle, there are fluctuations in the activity, such as the ejected levels of solar radiation, and in the appearance of the sun, such as changes in the amount and size of sun spots, solar flares and other phenomena that occur on the sun's surface.
These changes also affect phenomena on earth, especially the auroras.
Answer:
Earth's atmosphere is mostly made up of nitrogen and oxygen. Once the solar particles reach Earth's atmosphere, they collide with atoms of nitrogen and oxygen, stripping away their electrons to leave ions in excited states. These ions emit radiation at various wavelengths, creating the characteristic colors.
Explanation:
Answer:
The answer is A, to serve as an outgroup.
Explanation:
The study of any phylogenetic group requires that there must be an outgroup that can serve to understand which characters are plesiomorphic (or ancestral) and how they changed over the years to a new evolved character. In this case, Lily, since it is not a member of the group which is under study (orchid), serves as an outgroup.
