Answer:
C. Simple diffusion
Explanation:
Simple diffusion from a high to low concentration is the most direct method that ions or molecules can move across a cell membrane.
Through this method, no proteins are required for transport, and no energy is used.
The ion or molecule being transported directly moves across the cell membrane, without any other factors involved.
So, the correct answer is C. Simple diffusion
B, light if i’m thinking about it right. My bad if it’s wrong, it seems reasonable!
Answer:
Coral reefs are built by coral polyps as they secrete layers of calcium carbonate beneath their bodies. The corals that build reefs are known as “hard” or “reef-building” corals. ... The coral polyps that build the reef survive by forming a symbiotic relationship with microscopic algae called zooxanthellae.
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.
