1.all living things are made up of cells
2.Cells are the smallest units of life
3.all cells come from preexisting cell though the process of cell division
Likely, B is the expected answer.
_____
As one who has suffered health problems for more than 40 years due to the desire of certain chemical industries to make money by polluting my food, I can barely remain civil when discussing genetic modification. Plants with built-in pesticides are bad news on so many levels it would take a library of books to discuss them all. What, after all, is the benefit of efficiently producing poison?
As newer rock layers form, they overlap with the ones with the pre-existing ones. Therefore, when looking for older rock layers, we would look for the ones that are deeper beneath the surface of the earth. On the other hand, newer rock layers are found at the top. This is also observed in the fact that oil rigs dig very deep into the ground to access the layers that are millions of years old.
So mitosis will start with interphase which will be the longest step. Inside of interphase there will be and S phase where the DNA will be copied. Then the PMAT phases then these phases are where the cell is actually dividing and it ends with cytokinesis with the cell splitting one membrane into two different membranes.
Answer:
B. Carbon dioxide
Explanation:
First of all, let’s write out the photosynthesis equation to identify the products and reactants.
6CO2 + 6H2O + energy —> C6H12O6 + 6H2O
In a chemical equation with the arrow pointing right, the reactants are on the left and the products on the right.
In photosynthesis, the reactants, carbon dioxide, water, and energy, react to form the products of glucose (sugar) and oxygen.
Now, let’s look at the answer choices. We can automatically eliminate choices A (oxygen) and D (sugar) because they are products.
We are left with B (carbon dioxide) and C (water). Water isn’t really considered a major contributor to climate change. Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, causing climate change.
Therefore, the best answer choice is B. Carbon dioxide
