Answer:
Capillary action refers to the motion of the liquid along the solid surface resulting due to the attraction of the molecules of the liquid. Capillary action is used by the plants to bring water up to the roots and then from stems to the remaining parts of the plant. The liquid molecules are fascinated by the molecules present within the stem. This attraction is utilized to assist the water to move up from the ground and to get distributed to all the parts of the plant.
There are three intermolecular forces that play an essential role in the procedure of capillary action:
1. Adhesion refers to the procedure of combining one substance with another. In plants, adhesion permits the water to attach with the plant's organic tissues.
2. Cohesion maintains the molecules of a similar substance to remain in combination. In plants, cohesion makes the molecules of water to stay together.
3. Surface tension refers to the influence of the intermolecular attraction, which makes liquids to produce a top or outer layer that works like a kind of thin film. Surface tension is accountable for the water drops to attain its shape and for holding the compositions together as plants soak up the water.
The question seem to be incomplete but I found the complete question which is:
If you are performing this test on an unknown organism, why is it a good idea to run simultaneous tests on known phenylalanine-positive and phenylalanine-negative organisms?
Here is the Answer:
Inoculation of a positive control and success from it includes certainty to negative outcomes on an unknown organism. That is, you know the test is working effectively, so the negative outcome is most likely precise. Without the positive control, there is dependably a component of uncertainty whether the negative outcome is a genuine negative or a false negative. performing the test on a known phenlalanine-negative organism is valuable in that it exhibits what a negative outcome looks like.
The answer is <span>hygrometer, will.
</span><span>Your <u>hygrometer</u> indicates that the relative humidity is very high. Rain probably <u>will</u> occur.
Hygrometer is an instrument used for measuring the relative humidity in the atmosphere. If the relative humidity is very high, then it rain will probably occur and vice versa.
Anemometer is an instrument used for measuring wind speed, thus it cannot be the right answer.</span>
Answer:the part of the brain that has most likely been damaged in this experiment is the suprachiasmatic nucleus (SCN) found in the hypothalamus of the brain.
Explanation:
circadian rhythms are behavioural changes that respond to light and darkness in an organisms environment. The sleep-inducing wake cycle is a good example of a circadian rhythm. In the experiment, the disruption of the mouse SCN led to development of imbalances in the circadian rhythm of sleep and wake cycle leading to falling asleep and waking up at random times of the day and night. I hope this helps. Thanks
