It basically means the oldest rocks and newest rocks are organized from top to bottom, like a bunk bed, oldest at the bottom, newest at the top in chronological order.
Answer:
A. division of the nucleus
Explanation:
Mitosis is a biological process that the cells of all organisms go through in order to replicate and reproduce. It is part of the cell cycle, which is made up of G1, S, G2, and M (mitosis). In G1, the cell is growing; in S, the DNA of the cell is synthesized, or replicated, so we know choice C is wrong; in G2, the cell is being prepared for mitosis; and finally, in M, the cell actually undergoes cell division.
So, we are looking for an answer choice that involves division: either A or D.
At the end of mitosis, there's an additional process called cytokinesis that actually divides the cytoplasm, so the answer can't be D.
Thus, the answer is A.
Answer:
A. III only
Explanation:
Cytochromes are found only in the mitochondrial membrane as part of the electron transport chain. They are vital to the downward cascade of energy as electrons are passed from the NAD+ and FAD produced during glycolysis and the Krebs cycle into the electron transport chain to eventually produce ATP.
The typical light microscope at its maximum magnification power has a resolution of 200 nm. The light microscope is able to view and distinguish between two lines or points that are no less than 200 nm apart. Since our membrane of interest is 8 nm apart, it won't be visible under the light microscope. Several such membranes are needed to lined side by side to make the viewing possible. The number of membranes should be, 
= 25.
Answer:
D. All scientists will be using one name for mountain lions.
Explanation:
Different names are given to the same animals around the world which is difficult for the scientist or people to memorize every name. So for that reason scientist chose a taxonomic system in which a scientific name was given to every specie that are living on earth. Scientists used a specific language for naming of different organisms i. e. Latin or Greek language.
