. If energy is the ability to cause change, then what evidence is there that energy is produced in the interaction between the wind and the blades of the wind turbine?
Answers
Answer:
Explanation:
Wind is considered to be kinetic energy. As the kinetic energy of the wind hits the fans of the wind turbine it causes the fans to spin. This then causes the blades to spin a rotor which is connected to the main shaft of the turbine itself. This rotor spins and generates electricity. Therefore, the kinetic energy that was initially introduced into the system goes through a process and gets converted into electrical energy which we can use.
What is the structure that breaks the spindle fiber into 2?
Help !!
Answers
Answer:
The centromeres
Explanation:
The KINETOCHORE is the cellular structure that breaks the spindle fiber into TWO.
The kinetochore is a structure that associates the duplicated chromatids in eukaryotic cells to spindle microtubules during cell division (either mitosis or meiosis).
The kinetochore forms at the centromere of the chromosomes.
The kinetochore is a disk-shaped structure made up of more than 100 different proteins, especially constitutive centromere-associated network (CCAN) proteins.
In conclusion, the KINETOCHORE is the cellular structure that breaks the spindle fiber into TWO.

What is the difference between a biome and a microhabitat
Answers
The difference between a biome and a microhabitat are as follow:
Microhabitat: A microhabitat is a small specialized habitat within a larger habitat. An example of a microhabitat is a caterpillar snacking on leaves that have fallen from a walnut tree in the orchard.
Biome: A biome is a large region of Earth that has a certain climate and certain types of living things. Major biomes include tundra, forests, grasslands, and deserts.
What is a habitat?A habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive.
Hence, microhabitat is a small specialized habitat whereas biome is a large region.

In the Osmosis Gizmo, the cell is placed in a very small chamber. Suppose a cell is placed in a large container of water with a very low solute concentration. What do you think would happen
Answers
Answer:
If a cell is placed in a large container of water with a very low solute concentration the solution will be hypotonic in nature. The water will enter inside the cell through semi-permeable membrane of cell. The cell will swell.
A gummy bear was left in a beaker of distilled water overnight. The gummy bear on the left was the original gummy and the gummy on the right was the resulting bear.
Explain what happened to the volume of the gummy bear that was left in distilled water. Use CER format to construct your answer.
Answers
Answer: The tap water contains impurities that the gummy bear was already at an equilibrium with. Therefore, if it is placed in distilled water; it would be placed in a hypotonic solution. This would cause it to swell even more and become more fragile.
Explanation:
The Gummy Bear has a partially permeable coating that allows water molecules to pass through while blocking larger molecules. Water molecules move into the bear in this osmosis experiment, enlarging it.
What is endosmosis?Endosmosis is the movement of water within cells when placed in a hypotonic solution. Water movement causes the cell to swell.
The swelling of the cells is caused by endosmosis. Exosmosis occurs when cells are placed in hypertonic solutions, resulting in cell shrinkage.
Isotonic solutions have a similar water potential to the cytoplasm, so neither endosmosis nor exosmosis occurs.
The mobility of solvent into the cell is referred to as endosmosis. The progression of solvent out of the cell is known as exosmosis.
The solvent flows from the extracellular environment into the cell. The solvent flows from the cell into the surrounding solution.
Thus, the process of endosmosis will occur in the given situation that causes that bear to swell.

Claim 2: The magma that formed the Rocky Mountains came from the rock of the Great Plains.
Choose the claim that is best supported by evidence, explaining why the rock of the Rocky Mountains and Great Plains have surprisingly similar mineral compositions.
Answers
Answer: It is claim 1
Explanation: It is 1 as the Rocky Mountains weathered down into sediments which was then compacted into sediment rocks
The appropriate claim is Claim 1: The sediment that formed the Great Plains came from the rock of the Rocky Mountains.
It should be noted that the sediment that formed the Great Plains came from the rock of the Rocky Mountains. As the Rocky Mountain was eroded by erosion, there were sediments that were produced.
Cenozonic-era volcanism and erosion resulted into sediments and the sediments were transported and were later deposited to form the Great Plain. Therefore, the first claim is logically true while the second claim is incorrect.

Answers
Answer: The correct answer is
A disease caused by an uncontrolled division of abnormal cells in a part of the body.
Explanation:
This is because cancer is a disease that occur when the normal body mechanism changed and stop working whereby old cells refuse to die and there is uncontrollable replication of abnormal cells in the body . This uncontrollable division of cells tend to want invade and spread to part of the body thereby forming tumors and some cancers don't form tumors such as lukemia.

Answer:
Stores nutrients and cellular waste products.
Explanation:
Vacuole is a space that is line with membrane and within the cell that lacks cytoplasm but filled with fluid.
They are important cytoplasmic organelles and perform certain functions such as storage, ingestion, digestion, excretion, and expulsion of excess water.
In plant, large central vacuoles enable them to attain a large size without accumulating the bulk that would make metabolism difficult.
