PLS HELP BIG GRADE 5. Water stored in a reservoir is used to generate electricity as it flows down and into a river. The river flows to the ocean, where it evaporates to form clouds. Rain falls from the clouds into streams that flow into the reservoir.
Which location of the water has most potential energy? Assume the amount of water in each place is the same. These are the locations: 1. where it enters the river from the reservoir, 2. when it is in the ocean, 3. when it is in the reservoir, and 4. when it is in the clouds.
1. Where it enters the river from the reservoir.
2. When it is in the ocean.
3. When it is in the reservoir.
4. When it is in the clouds.
Explain your answer.
Answer: Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity.
Explanation: Hydroelectricity can be defined as the generation of electricity by utilizing the speed of water stream in a reservoir of water. The high speed water current is used to move the water turbine the energy produced in the turbine can be used to generate electricity by the generator.

descendants?
A) causation
B) correlation
C) natural selection
D) transitional fossils
The intermediate states between an ancestral form and that of its
descendants are transitional fossils.
What is a transitional fossil?
Transitional fossils are remains of an organism that came in between a known version of a species and the current species.
Transitional fossils would be proof of evolution because they would show medium forms of a species and they altered and accumulated adaptations at a slow pace.
Thus, option "D" transitional fossils are correct.

Besides the interaction between animals and plants, what other factors may be involved in the carbon and oxygen cycles?
Answer: .co2
Explanation: co2
The other factors which are involved in the carbon and oxygen cycles are air, ground, respiration, and photosynthesis.
Which factor contributes to the carbon cycle?
Explanation: Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere.
How do plants and animals interact with the carbon cycle differently from one another?Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood, and leaves decay bringing the carbon into the ground.

Answer:
- Contains myelinated axons: White matter
- Posterior column: White matter
- Located to the periphery of the spinal cord: White matter
- Gracile fasciculus: White matter
- Anterior spinocerebellar tract: White matter
- Medial vestibulospinal tract: White matter
- Marked by low myelination: Gray matter
- Functions to integrate arriving electrical signals: Gray matter
- Contains somas, synapses, and dendrites: Gray matter
- Tectospinal tract: White matter
- Functions to transmit electrical signals rapidly over long distances: White matter
- Lateral horn: Gray matter
- Ventral horn: Gray matter
Explanation:
Both the brain and the spinal cord contain white matter and gray matter. White matter is the tissue responsible for information transmission (i.e., axons); whereas gray matter is mostly involved in information processing (i.e., neuron bodies). White matter is composed of myelinated axons which extend out from the neuron bodies and glial cells, and this tissue connects different areas of the cerebral cortex (i.e., the outer layer of the brain). Moreover, gray matter is composed of neuronal cell bodies or 'soma' that contain the neuron’s nucleus and unmyelinated axons. Gray matter also has glial cells and capillary blood vessels; whereas white matter also has oligodendrocytes that produce myelin and astrocytes. The color of the white matter is caused by the myelin that surrounds the axons; while the color of the gray matter is due to the capillary blood vessels and neuronal cell bodies. In the cerebrum and cerebellum, white matter is observed in deep areas coated by gray matter; whereas, in the spinal cord, the white matter surrounds the central gray matter. White matter is involved in normal motor and sensory function, this tissue is responsible for learning and coordinating communication between different brain regions. Moreover, grey matter is involved in muscle control and sensory function (e.g., hearing, vision, memory, emotions, speech, decision making, etc).

During the Cardiovascular Function Labster simulation, cardiac output did not increase as much as oxygen consumption rate (which increased 8x), what is the most likely mechanism that could allow increased oxygen delivery by the cardiovascular system
Answer:
An increase in the rate of oxygen that has been removed from hemoglobin could increase the supply of oxygen by the cardiovascular system.
Explanation:
Hemoglobin is a protein, present in the cardiovascular system, whose main function is to remove oxygen from the lungs and take it to the tissues of the human body. Therefore, the more oxygen is removed from the hemoglobin, the greater the oxygen supply. This applies even in the situation presented in the question above, where cardiac output did not increase in the same way as oxygen consumption. In this case, if oxygen consumption is high, the removal of oxygen from the hemoglobin must be increased to supply this consumption.
