The roller coaster is your favorite ride! but the line is always long! having just studied potential and kinetic energy in physics, you evaluate the energy changes of the cars as they move on the tracks. Compare the potential energy of the cars if they are stopped at points A to point D.
A. Neither have potential energy.
B. The potential energy is the same.
C. Potential energy is greatest at point D.
D. Potential energy is greatest at point A.
Answers
Potential energy is greatest at point D. Therefore, option C is correct.
What is potential energy?Potential energy is the energy that is stored inside of an object due to the object's position, state, or arrangement. When an object's position, status, or configuration changes, the energy that has been stored in it is released.
The gravitational potential energy of an item, the elastic potential energy of a stretched spring, and the electric potential energy of an electric charge in an electric field are examples of common types of potential energy.
Potential energy depends upon the mass and height of the object. The greater the mass and height, the greater will be the potential energy of the object. The height of position D is maximum, therefore potential energy is greatest at point D. Hence, option C is correct.

Describe the process of oxidation in terms of electrons AND energy.
Answers
Oxidation is described as the loss of electrons and energy by a molecule.
OXIDATION:Oxidation is a process whereby a molecule loses electrons (e-) or energy to become positively charged. Oxidation changes the oxidation number of the molecule involved depending on the number of electrons lost. Reduction is the opposite of oxidation, and it entails gain of electrons and energy by a molecule. Together, they are called oxidation-reduction or redox reaction.Learn more about oxidation at: https://brainly.com/question/3867774?referrer=searchResults

O symbiotic species
Answers
The term that would best define the fish added to the pond is INTRODUCED species. These species may be harmful to native species.
Introduced species are exotic species which has arrived there by human activity, which may be harmful to native species.
Introduced species may even be harmful to the entire ecosystem because they can break the delicate equilibrium of the ecosystem.
Introduced species may compete with native species for limited resources (e.g., water resources, foods, habitat, etc).

Considering that cells vary in shape,what other dimensions or parameters of the cell could be used to estimate cell size?
Answers
Answer:
Three general factors determine cell shape: the state of the cytoskeleton, the amount of water that is pumped into a cell, and the state of the cell wall. Each of these three factors is highly dynamic, meaning they are constantly in flux or can be suddenly changed. This dynamism is how cells can vary in shape.

Hormones exert an effect only on a gland or organ that has a ________ where that specific hormone can bind.
Answers
Hormones excite, inhibit, or regulate the activity of other organs when they exert their effect on a target cell where that specific hormone can bind.
A hormone is the substance secreted by certain glands that promotes, blocks or regulates the activity of the organs.
Target cells are cells that possess specific receptors for hormones on their surface.The recognition of a hormone by its target cell lies in the presence at the cellular level of glycoproteins, called receptors, which bind specifically to the hormone, with high affinity and in a reversible way.Receptors present some differences related to the type of hormone or neurotransmitter to which they bind, with their location in the cell and with the way of transferring information after their union with these molecules.Therefore, we can conclude that hormones are produced by certain glands, circulate through the blood and reach other cells called target cells, exerting a regulatory effect on them.
