Answer:
The steps of photosynthesis are mostly the same for both the plants of desert and temperate regions. The only difference is that desert plants take up carbon dioxide at night and store it as an organic acid inside the body.
Explanation:
Answer:
Option (A).
Explanation:
Lac operon system in bacteria explains the lactose metabolism in the cell. The first operon system was discovered by Jacob and Monod. Operon may be defined as the cluster of genes that are transcribed as a single RNA unit.
The bacteria uses glucose if glucose and lactose are present in the media. The bacterial cell can recognize the glucose presence as CAP-cAMP complex are required for the process of transcription and the complex level is low in the presence of glucose. This way bacteria turns off transcription for lactose genes even when the lactose is present.
Thus, the correct answer is option (A).
Percent error is a statistical tool used for evaluating precision. It is expressed as:
Percent error = | (experimental value - theoretical value) / theoretical value | x 100%
Experimental value represents the calculated value while the theoretical value represents the known value. A percent error value which is approaching zero means that your experimental value is close to the known value. Which can possibly mean that you have precise measurements. Calculations are as follows:
Percent Error = | (2.54 - 2.70) / 2.70 | x 100 =5.93%
Thus, the answer is b. 5.93%.
believe the correct answer from the choices listed above is option A. The two principal ways to describe Earth’s structure are based on the chemical composition and thickness of layers. Since Earth is a layered structure, it is viewed according to its different chemical composition and the thickness.
Best Answer: Well, you have to look at the onion slide under the microscope and looks at each cell and tell what stage (interphase, prophase, etc.) they are in. and then for the description probably tell which one there is the most of and maybe why you think that is. You can find pictures of each phase in your book. I did a lab like this not too long ago in my bio class lol. And, i believe that you will get a lot in interphase (when cells are not currently dividing), just to let you know.
