Answer:
D. The process requires energy that is provided by ATP.
Explanation:
Neurons use a pump called the sodium-potassium pump, which normally pumps sodium ions out of the cell and pumps potassium ions into the cell.
This pump goes against the concentration gradient to create the resting membrane potential.
Since the pump goes against the concentration gradient, it requires energy, because it is not passive diffusion.
So, D is the correct answer, as the process requires ATP energy.
Neurons are cells of the nervous system. As part of its normal function, a
neuron pumps sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell. The process requires energy that is provided by ATP. The correct answer is option D.
What is the role of sodium potassium pump ?The role of the sodium potassium pump is the muscle contraction and the nerve impulse. In exchange of 2 potassium ions is the displacement of 3 sodium ion and this exchange is against the concentration gradient thus requires the molecule of ATP for the transfer of the ions.
The Na+/K+-pump an active transporter uses ATP hydrolysis in energy source to move ions across the neuronal membrane down their concentration gradients and assigned specific functions associated with the generation of the action potential as well as with the maintenance of other active transport.

How is mRNA produced during the process of DNA transcription
Answer
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.

Some tools contain permanent magnets. What two types of materials could these tools pick up?
A. Materials that contain a magnetic material, such as iron
B. Materials that contain glue or other adhesives
C. Materials that contain other magnets
D. Materials that contain a ceramic, such as glass
Permanent magnets are the objects producing the invisible magnetic field. The tools containing the permanent magnets will pick the magnets and iron. Thus, options A and C are correct.
What are permanent magnets?Permanent magnets are the magnetic field-producing materials that pull or repel the ferromagnetic materials towards or away from themselves. The magnetic field is produced from the internal magnetic material.
They are formed when the ferromagnetic objects are heated at high temperatures and have those properties for a very long time. These magnets can attract objects that have magnetic fields around them like iron and other magnets.
Therefore, a permanent magnet will attract magnets and magnetic materials like iron.

A scientist is adding thermal energy to a sample of water. Using the Law of Conservation of Energy, what can you predict will happen? (3 points)
The water will increase in temperature beyond the amount of thermal energy that is added, because more energy will be created in this experiment.
The water will decrease in temperature as thermal energy is added, because it cannot create more energy or matter.
The water will not change its temperature because energy cannot be created or destroyed.
The water will increase in temperature in proportion to the amount of thermal energy that is added, but some will be lost to the environment.
Answer:
you can predict that the scientist is using thermal energy and is making the tempature hotter

In an ecosystem, what happens to the atoms of certain chemical elements, such as carbon, oxygen, and nitrogen? * They move into and out of living systems. O They are only found in abiotic factors. O They move out of living systems and do not return. O They move into living systems and remain there.
Answer:
They move into and out of living systems
Explanation:
The gases in an ecosystem like carbon, nitrogen, and oxygen all move into and out of the living systems through the process of animal respiration and plant absorption of carbon and release of oxygen. They are found on diffused forms in blood and cells of body, can be found in aquatic and terrestrial components. They are processed through animal wastes and in the consumption of matter.Which statement concerning blood pressure is not correct?

What is the structure labeled Y? the nucleus a chloroplast a cytoplasm the endoplasmic reticulum
Answer: Eukaryotic cells — those that make up cattails and apple trees, mushrooms and dust mites, halibut and readers of Scitable — have evolved ways to partition off different functions to various locations in the cell. In fact, specialized compartments called organelles exist within eukaryotic cells for this purpose. Different organelles play different roles in the cell — for instance, mitochondria generate energy from food molecules; lysosomes break down and recycle organelles and macromolecules; and the endoplasmic reticulum helps build membranes and transport proteins throughout the cell. But what characteristics do all organelles have in common? And why was the development of three particular organelles — the nucleus, the mitochondrion, and the chloroplast — so essential to the evolution of present-day eukaryotes.

How does cellular respiration happen?
Answer in a minumum of 5 complete sentences
Answer:
Definition : "Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products."
Simplified : Cellular respiration is used to take in food, then is used to create ATP. ATP is a chemical the cell uses for energy. This process is called aerobic respiration. The process uses oxygen, and has four stages known as Link reaction, glycolysis, the Krebs cycle, and the electron transport chain.
