The answer to this question would be: False
The rate of diffusion should not be influenced by molecular weight. Big molecule might not be able to pass the membrane though.
Diffusion happens when there is a difference/gradient in the concentration of the molecules. If the difference is higher, then the diffusion rate will be increased.
Irrigation is an artificial technology that helps to obtain water and thus recover the loss in extensive (wheat) crops.
<h3>What is irrigation?</h3>
Irrigation is a technology based on the artificial supply of water to recover crops from drought conditions.
Genetic modification may also help with drought conditions by inserting into the genome of the target species gene sequences associated with hydric stress (e.g., a protein channel to close stomata at night).
In conclusion, irrigation is an artificial technology that helps to obtain water and thus recover the loss in extensive (wheat) crops.

Answer:
b. Aldosterone promotes sodium reabsorption in the kidneys.
Explanation:
Once it is produced by the adrenal gland it stimulates the mineralocorticoid receptors on the distal tubule and collecting duct of the kidney's nephrons. This causes sodium reabsorption in the kidneys indirectly affecting water retention.
Regarding cellular phones, the <u>electronic serial number (ESN)</u> is a code used to reset a forgotten pin.
- An electronic serial number (ESN) is the distinctive identification number that the manufacturer embeds or inscribes on the wireless phone's microchip.
- The ESN is automatically sent to the base station each time a call is placed so that the mobile switching office of the wireless carrier can verify the legitimacy of the call. In the field, the ESN cannot be easily changed.
- The mobile identification number (MIN), which is used by wireless carriers to identify phones on their network, is different from the ESN.
- To aid in preventing fraud, MINs and ESNs can be electronically checked.
