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 1

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 2

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:

A car drives 150 m to the east then backtracks 30 m to the west. Describe the mathematical operation you will use to determine the net movement of the car.

Answers

Answer:

Subtraction operation

The car's displacement is  120 m west

Explanation:

Given;

first motion of the car as 150 m east

second motion of the car as 30 m west

The mathematical operation that will be used to determine the net movement of the car is subtraction operation.

The net movement of the car is the car's displacement.

Displacement is given by;

D = final position - initial position

D = 30 m - 150 m

D = - 120 m

The negative sign is direction = west ward direction

Thus, the car's displacement = 120 m west

450

Answers

Answer: the carrying capacity for adult giraffes in this area is: 6.

Explanation: [ 450 pounds divided by 75 = 6. ]

Fun Fact - Giraffes can drink up to 10 gallons of water a day and spend 16-20 hours a day feeding, their favorite food is Acacia Leaves.

Adult giraffes eat 75 pounds of food in a day. On average, an area can provide 450 pounds of food per day for giraffes.

The carrying capacity for adult giraffes in this area are 6.

How the carrying capacity for giraffes in given area is determined?

Adult giraffes eat = 75 pounds of food per dayArea provides = 450 pounds food per day

so, carrying capacity for giraffes in the area equals,

 food provided by are per day\ food eater by giraffes in a day

=450\75

= 6.

Hereby, carrying capacity of giraffes in this area is measured.

how does the concentration of electrolytes in and outside a cell control the movement of water

Answers

Answer:

Maintaining an isotonic environment for the cell ensures that the cell does not shrink or swell due to water.

Explanation:

If the cell was in a hypotonic solution, water would rush in the cell causing it to burst, and if it was in a hypertonic solution it would cause water to move out of the cell, causing the cell to shrivel. It is important that the cell is always in a solution with an almost equal electrolyte solution inside the cell

can anybody help me with this?

Answers

Answer:

presence of sugar means that the outside of the fruits is less dilute (more concentrated in sugar than water) than the inside of the fruits

in osmosis (diffusion of water molecules), water molecules have a net movement from a more dilute substance to a less dilute substance

sugar is the less dilute substance, so water is drawn out of the fruits and mixes with the sugar around them

the sugar dissolves in water, creating a sugar solution

this results in fruits with less water inside them, and surrounded by sugar solution

Answers

Answer:

Experiments

Explanation:

The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.

How ever, they relied solely on reasoning while attempting to explain scientific observations. Contemporarily, science is highly empirical. The scientific process can only be complete when scientific observations are subjects to rigorous experiments in order go determine the actual relationship between variables and provide better explanation for scientific observations.

Hence the ancient Greek philosophers should have used experiments rather than sole reason in proffering scientific explanations to natural phenomena.
