Answer:

The correct answer is option A. a motor protein ATPase inhibitor.

Explanation:

Motor proteins are sub-atomic motors that utilize ATP hydrolysis to move along cytoskeletal filaments inside the cell. They satisfy numerous capacities inside the biological system, controlling the sliding of filaments for muscle contraction and intervening intracellular movement along biopolymer filament tracks.  

The two globular head motor areas in heavy chains can change over the chemical energy of ATP hydrolysis into mechanical work to move along microtubules.

Thus, in vitro experiment inhibitor of the motor protein, ATPase will be a control.

Match the rocks with the material they are made of. igneous rocks /sedimentary rocks /metamorphic rocks
Vlad1618 [11]

The answers would be:

Igneous Rocks - They are made from hot magma.

Sedimentary Rocks - They are made from weathered pieces of rock.

Metamorphic Rocks - They are rocks, small or large which reformed due to high temperature.

If you'd like to know more, read on:

Igneous rocks are formed when hot magma is cooled and then it hardens into a rock. The word igneous comes from the word, "ignis" which means "of fire. They can be formed beneath the Earth or on the surface.

Sedimentary rocks are formed from weathered pieces of rock. These pieces are called <u>sediments</u>. They can also be made out of other material. When these sediments settle, it continues to do so until so much sediment accumulate and they start to press down on each other. The sediments then start to go through compaction and sedimentation which for a sedimentary rock.

Metamorphic rocks form under heat and pressure. They are squeezed and shaped and go through <u>metamorphosis </u>or go through change. A metamorphic rock can be formed from any other type of rock as long as it goes through changes due to intense pressure and/or heat.

Contact [7]

Answer: C). Sensory neurons, D).motor neurons

Explanation: Sensory neurons are nerve cells that carry signals from the external parts of the body such as the skin, eyes, ear, nose (the sense organs) to the brain.

Motor neurons are nerve cells that carry information or messages away from the central nervous system ( brain and spinal cord) to the rest of the body such as the skin, muscles and glands.
