Answer: The one on the right
Explanation: Its shaped like a pyramid. The one on the left shows the food cycle.
If carbon dioxide is removed from a plant's environment, what would you expect to happen to the plant's production of high-energy sugars?The correct answer would be B, Fewer sugars will be produced.
12. Which of the following affects the rate of photosynthesis?
The correct answer would be D. All of the choices - water, temperature and light intensity - affects the rate of photosynthesis.
Answer:
The correct answer is A- B cells are activated and release antibodies
Explanation:
When an antigen invades a mammals body, specific immune cells engulf and ingest it. Some of the digested pieces are displayed on the cells bodies, the next step will be that B cells are activated and release antibodies.
Drop each ball from the platform three more times
. Reliability or precision means how much the measured values vary from each other when measured by performing the same experiment repeatedly. When measuring values by observation in physical experiments of this nature, it is best to perform the experiment and measure the values at least three times. The more the better. In such measurements there is always a margin of error, e.g., how at exact time you start and stop the stopwatch. There may also be a bit harder or softer side of ball (tennis ball strip) touching the ground. In order to minimize such and some other margin of errors, it is advisable to measure the values more than 3-4 times, and then take their mean. The value now obtained would be would reliable or precise. Second and third options are incorrect because they will have no effect on improving the reliability. In order for the fourth option to be correct, the other people need to do the same (not similar) experiment, with the same balls and same conditions/instruments. That would be equivalent to repeating the experiment 3-4 times, which is already covered by first option.
