20. What would happen to a paramecium that is placed in a jar of syrup?

Answers

Answer:

It will shrink.

Explanation:

When  a solution contains more solute than the surrounding environment  where ,it  is located,it is said to be hyper tonic.Such a solution is of higher concentration,and therefore contains little water.

Syrup is an example of an hype tonic solution.Corn syrup  as an example  contains more solute in it,

Paramecium is unicellular organisms which is aquatic in habitat,therefore compare to the syrup of high solute it is hypo tonic.

Thus when placed in syrup,Paramecium loses water by osmosis,since water from the Paramecium at lower concentration would move out through the paramecium membrane ,as semipermeable membrane,into the syrup,of higher concentration

The paramecium will eventually shrink,and die,due to dehydration.

Explanation:

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops. A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question. Part E How would you conduct your investigation? In your answer, explain your independent and dependent variables.

Answers

Answer

no .  you should give one plant natural fertilizer  and the other artificial fertilizer to decide which works the best

Explanation:

because it is made for tomatoes

Answer:

part E

The dependent variable is the growth rate of the plant. The independent variable is the type of fertilizer used over time. There will be three groups of tomato plants raised from seed: one group will be a control group without any fertilizer, the second group will be planted in soil with artificial fertilizer, and the third group will be planted in soil with compost. The height of the plants will be measured every five days, over a 30-day period.Explanation:

Which statement describes gravity, There is no define of measurement for gravity, Gravity is the force that pulls objects towards Earth's center, Objects that have a small mass will have no gravitational pull, Gravitational pull between two objects decrease as the mass of one increases.

Answers

Answer:

Gravity is the force that pulls objects towards the earth centre.

Explanation:

According to the postulation of Sir Isaac Newton, explaining Gravity using an apple falling down from a tree. He was so curious to find out why this happened. I hope this helps.

The statement which best describes gravity is that it is the force that pulls objects toward Earth's center. Thus, the correct option for this question is B.

What is Gravity?

Gravity may be defined as a type of force through which a planet or any other celestial body draws objects toward its center. It is only the force of gravity that specifically keeps all of the planets in orbit around the sun. This force attracts a body toward the center of it.

According to the context of this question, it is a fundamental interaction that causes the mutual attraction between things with mass or energy.

The best example of gravity is understood by throwing a ball high in the air, it will certainly be coming back to the surface of the earth after attaining its maximum height with respect to the energy by which is thrown.

Therefore, the statement which best describes gravity is that it is the force that pulls objects toward Earth's center. Thus, the correct option for this question is B.
