Which of the following is a demonstration of the polarity of water?A) A stream of water bending toward a balloon due to the balloon have a static charge from being rubbed on a sweater

B) Water clinging to each other and as a result forming a droplet on a penny

C) Water clinging to the side of a windshield after a rain

D)All of the above

Answer 1
Answer:

Answer:

D)All of the above is your answer
Answer 2
Answer:

Answer:

All of the above

Explanation:

In letter A, B, and C; in different physical situation the molecule of water behave and put in charge with its peculiar polarity. Remember that is part its quite simple and molecular structure.

Water is "dipolar", because there is an uneven distribution of electron density. Water has a partial negative charge (Delta-) near the oxygen atom due the unshared pairs of electrons, and partial positive charges (Delta-) near the hydrogen atoms.

Two reasons for the increasing demand for power are:a] reduced efficiency in appliances
b] population growth
c] relaxation of government regulations
d] increased consumption
e] reduced resources
f] global warming
g] hole in ozone layer

Answers

population growth

relaxation of government regulations

increased consumption those are the answers

Final answer:

The increasing demand for power is driven by reduced efficiency in appliances, population growth, and increased consumption. Reduced efficiency requires more power, population growth means more users, and increased consumption can be attributed to social and technological advances.

Explanation:

There are several reasons for the increasing demand for power, and in this case, we are focusing on three of them: reduced efficiency in appliances, population growth, and increased consumption.

Reduced efficiency in appliances means that more power is needed for these appliances to function, thereby driving up demand. On the other hand, population growth also leads to an increased need for power, because more people mean more use of appliances and technology that require power. Lastly, increased consumption, which may be a result of societal and technological progress, also contributes to the growing demand for power as people's lifestyles become more comfortable and more machine-dependent.

Animals are completely dependent upon plants for food. Even the animals that eat other animals are dependent on plants. Explain.

Answers

When the first consumer (herbivore) eats a producer (plant), the second consumer will have to eat the first consumer for food. So in order for the second consumer to live, the first consumer must live as well by eating plants. That is why the second consumer also need plants to survive. E.g. Plant is eaten by a rabbit and the rabbit eaten by a fox

PLZ HELP!!! I'm timed. I need answer as soon as possible. Will mark the brainliest if correct and ad a thanks with a rate of 5 too. thank you :) .Which definition best describes global warming?

a long-term change in the Earth's climate
a long-term increase in the Earth's average temperature
a long-term change in the climate of a region or a city
solar heat that is radiated out into space

Answers

Answer:

I think it's the 2nd one
B would be the correct answer and here is why

A is incorrect because climate is the weather conditions prevailing in an area in general or over a long period. Which means it only affects one area meaning that it is not “Global” so this also eliminates C.
D is incorrect because that is not talking about Earth

Plz mark as brainliest I took the time to explain why B is correct and also ensured you that it is correct through these explanations

What is the purpose of equilibration ?

Answers

Answer:Equilibration buffer provides a condition to ensure that the target molecules interact effectively with the ligand and are retained by the affinity medium as all other molecules wash through the column.So the buffer pH and ionic strength at optimal condition are responsible for this ligand-molecule interaction.I hope this will help you.
