A dam is built across a river to generate electricity. What is likely effect of the construction of a dam on the river?
a)increase in the size of fish in the river
b)increase in the water flow in the river
c)decrease in the population of aquatic organisms in the river
d)decrease in the amount of pollutants dumped into the river
Answer:
c i think
Explanation:
Most likely the effect of the construction of a dam on the river is that it decreases the population of aquatic organisms in the river. Thus, the correct option is C.
What is Population?A Population may be defined as the group of individuals significantly belonging to the same species living in the same area in a definite time period.
When a dam is built across a river in order to generate electricity, it results in the reduction of the population of aquatic organisms in the river.
This is because the whole construction affects the natural habitat of aquatic organisms as well as their adaptations. So, such populations are frightened due to external construction and do not play their essential roles.
Therefore, most likely the effect of the construction of a dam on the river is that it decreases the population of aquatic organisms in the river. Thus, the correct option is C.

Which of the following are sites where waste products are released from the body but not where they are produced
O skin and anus
O large intestine and small intestine
O liver and kidney
O tubules and ureters
Answer:
Its A skin and anus
(just did test)
Explanation:
The skin and the Anus are sites where waste products are released from the body but not where they are produced.
Which process of the human body eliminates the waste products?Excretion is the biological process through which any unwanted or waste products are eliminated from the body.
Large and small intestines produce waste products that are not completely digested by the stomach. The liver and kidney are also the sites of waste products like the removal of carbon dioxide and synthesis of urine respectively.
Therefore, the skin and the Anus are sites where waste products are released from the body but not where they are produced.

Which of the following data would support the claim that the gravitational force
between objects depends on mass?
O An object's weight can change depending where it is on Earth.
O A rocket can escape Earth's gravity by traveling at high speed.
O The further a planet is away from the sun, the smaller the gravitational force.
O Gravitational force is stronger on more massive planets.
Answer:
D.
Explanation:
gravitational force of attraction is stronger on more massive planets such as Jupiter
Gravitational force is stronger on more massive planets, the claim that the gravitational force between objects depends on mass, hence option D is correct.
What is gravitational force?The force that pulls things toward the center of a planet or other body is called gravity. All the planets are kept in orbit around the solar by gravity.
Earth is subject to the same gravity pull that you are. But your force doesn't really affect our globe because Earth is so much larger than you are.
In our world, gravity the moon is maintained in its circle around Earth by gravity, as are the planets in their orbits around the sun. The gravitational force is equivalent to your weight when you are at rest on or near the Earth's surface.
Therefore, gravitational force is stronger on more massive planets, hence option D is correct.

identify the type of solution (Hypotonic, Isotonic and Hypertonic) in each of the beakers. Write your answers as A=..., B=..., C=...
Answer:
Beaker A= Isotonic
Beaker B = Hypotonic
Beaker C= Hypertonic
Explanation:
ISO means the same on each side.
Hypo means less.
Hyper means more.
Beaker A= Isotonic
Beaker B = Hypotonic
Beaker C= Hypertonic
what is the difference between Isotonic Hypotonic Hypertonic?Isotonic: Isotonic solutions are solutions having equal osmotic pressures.Hypotonic: Hypotonic solutions are solutions having lower osmotic pressures.Hypertonic: Hypertonic solutions are solutions having comparatively higher osmotic pressures.The main difference between isotonic hypotonic and hypertonic solutions is that isotonic solutions are solutions having equal osmotic pressures while hypotonic solutions are solutions having lower osmotic pressure and hypertonic solutions are solutions with high osmotic pressure.

How do mountains affect the climate of a region?
(giving brainlist)
Answer:
As context, there are two sides of a mountain range:
A) The windward side
B) The leeward side
As mountains are tall, they block clouds which are in the troposphere. All the moisture thus falls onto the windward side, while almost none of the moisture from the rain gets to the leeward side.
In a nutshell, mountain ranges create barriers for precipitation which blocks off moisture to the leeward side, creating deserts.
This is why you see mountain ranges near deserts.

Sophie visited Carlsbad Caverns with her family during her summer vacation, and she was amazed at the cave’s formations. She learned that the cave was formed from minerals.
Rearrange the phrases describing one of the ways minerals form into the correct order. Place the earliest stage of mineral formation at the top. Place the final stage at the bottom. (Write 1 2 3 or 4 in order)
1. a solution forms from a liquid and dissolved substances
2. a warm solution flows through a crack in the rocks there
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
BASICALLY SAY WHICH STEPS GO FIRST IN MINERAL FORMATIONS! PLESSS
Answer:
The ways through which the minerals form include the following order:
2. a warm solution flows through a crack in the rocks there
1. a solution forms from a liquid and dissolved substances
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
Explanation:
From the explanations above, it could be seen that a warm solution (most probably water) flows through the cracks in the rocks leading to dissolution of substances to form liquid. When the liquid cools, the elements leaves and crystallize as compounds.

does photosynthesis remove take or use co2 from atmosphere?
Answer:
Take in
Explanation:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

What might happen to a desert biome if the area received more rain than it normally receives over an extended period of time? Describe some of the changes that you might expect to see
Answer:
Desert biome will change.
Explanation:
Desert biome will change if the area received more rain than normal it receives over an long period of time because the vegetation on that area appears. The change in rainfall pattern in the desert area changes the animals present in this region because the temperature of the desert is no longer suitable for the desert animals so they migrated and other organisms come to this place.

A cell has undergone determination to become an epithelial lung cell. If it is transplanted to a leg muscle, what do you think will happen to this cell?
Answer:
Change occur in form and structure of the cell.
Explanation:
The structure and shape of the cell change because the function of leg is different from the lungs. In the lungs the epithelial lung cell is responsible for the detection and protection of the cells against pathogen while on the other hand, the leg has the function to move an individual from one place to another so due to difference in function, the cells of both regions have different shape and structure of the cell and the epithelial lung cell will be changed into a leg muscle cell.
