The correct option is A.
A basic solution has a high concentration of hydroxide ions more than any type of ion and that is why it is basic in nature. An acidic solution has a higher concentration of hydrogen ions and that is why it is acidic in nature. A neutral solution has equal amount of hydroxide and hydrogen ions. Solutions are usually classified as either basic or acidic based on their hydrogen ion concentration.
Answer:
Temperature is a non-living factor in an organism's environment.
Explanation:
Non-living factors is also called abiotic factors. These factors have a great affect on the organisms growth and survival. With the help of abiotic factors i. e. sunlight, some organisms make their own food such as plants and algae. Some organisms lives in water which is abiotic factor such as fishes. Without these abiotic factors, all the organisms will die.
<span>When addressing a counterclaim in an argumentative essay, it is important to A. consider how the counterclaim reinforces the main position of your argument.
You need to take your opponent's counterclaim into consideration and turn it to your advantage - if you can manage to take their arguments and present them so as to reinforce your own, then you are surely going to win.

Answer and Explanation:
Cyclins and cyclin-dependent protein kinases (CDPKs, cell proteins) also function to control the cell cycle. A group of cyclins: the G1 cyclins, are synthesized during G1 phase and function to activate CDPKs which initiate DNA synthesis at the G1/S checkpoint. The cell fails to progress to S phase if there is no sufficient synthesis of G1 cyclins. After a cell passes through this point, the G1 cyclins are degraded, allowing for another group of cyclins: the M cyclins (mitotic cyclins) to be synthesized. M cyclins activate a second group of CDPKs which allow the cell to pass the G2/M control point and into mitosis.
In the G1/s check point, entrance into the S phase is blocked if the genome is damaged. In the G2/M check point, entrance into the M phase is halted if the DNA replication is incomplete. In the M phase, anaphase blocked if chromatids are not properly assembled.
