Answer:Radiometric dating allows us to indirectly date fossils up to billions of years old based on minerals in surrounding volcanic strata. The correct option is D.
Explanation:
Radiometric dating was first used by geologist after being published by Bertram Bollywood in 1907. During volcanic eruption, some minerals ( carbon) are trapped within the volcanic strata. These minerals are made up of radioactive isotopes which are unstable as they form decay products with a known constant rate of decay. This enables them to :
- access information about the absolute age of rocks,
- date a wide range of natural and man-made materials
- know even the age of earth. I hope this helps. Thanks
A. because the iced tea mix dissolves in the water therefore it is a solvent <span />
Answer:
more information is needed, because organisms from both the bacteria and archaea domains are prokaryotic and unicellular.

Answer:
FERTILIZATION
Explanation:
Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition. Thus, sexually reproducing organisms alternate between haploid and diploid stages. However, the ways in which reproductive cells are produced and the timing between meiosis and fertilization vary greatly.
Answer:
C
Explanation:
First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!
