Biology

Nastasia [14]3 years ago
6 0

Answer:

Explanation:

The type of battery that Jackson's toothbrush is using is a secondary cell; this is because it can be recharged (meaning the electrochemical reactions taking place in the battery can be reversed). Batteries generally work in such a way that, while using it, electrons move from the anode of the battery to the cathode. In primary cells, this process continues until there are no electron to be transferred from the anode to the cathode and then the battery "dies" and is disposed. <u>But in a secondary cell, just like the battery of Jackson's toothbrush, when the battery is been recharged, the electrons start moving from the cathode back to the anode; which makes electrons available again in the anode for use</u>.

This is more of a psychology question but why does the mind procrastinate and what helps it stop?
Pie

people procrastinate because they're avoiding something they know will make them emotionally unpleasant by doing that task, so instead, they do something that provides a temporary mood boost. Procrastination itself causes shame and guilt, leading people to procrastinate even further.

your physical abilities rely a lot on your mental strength, if you feel like you've been procrastinating, try doing things to boost your overall mental health.

Which explains how interference is avoided between the signals that cordless phones receive and the signals that they broadcast?
aliya0001 [1]

Answer:

the signals have different frequency

Explanation:

The way that interference is avoided in these cases is that the signals have different frequency. Cell phone signals travel in a very specific wavelength, how often this wave repeats in a given span is called the frequency. By having these signals in different frequencies it prevents the signals from mixing with each other and instead allowing them to reach their destination intact. Otherwise, the signals would combine into a mess of uncomprehensible data, which is what we call interference.

Which of the following statements about eutrophication is TRUE?
Nostrana [21]

Answer:

C. It is driven by natural processes like rock weathering and nitrogen fixation.

Explanation:

It has been discovered that eutrophication occurs through a gradual increase in the deposition of phosphorus and nitrogen and other plants nutrients in the water bodies.

This will allow the maximum growth of algae on the surface of the water.

It has been discovered that eutrophication is not good for the water bodies. This is because, the excess growth of algae on the surface of the water will prevent the sunlight from penetrating the water, thereby preventing the plants inside the water from making use of the sunlight to carryout photosynthesis. Also, it will prevent oxygen from entering, thereby depriving the organisms in the water from having the necessary oxygen needed for respiration.
