If red blood cells are placed in distilled water and examined under a microscope
no cells are seen.
Explain why no red blood cells would be seen
Answer:
The distilled water made the red blood cells burst.
Explanation:
Distilled water is a hypotonic solution containing ZERO salt content. It is 100% water, making the red blood cells (RBC) take in water that causes the RBC to swell, then burst.
Describe the process of oxidation in terms of electrons AND energy.
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

How do gravity work?
Answer:
Gravity makes the Earth constantly pull us down. ... The force of gravity depends on the mass (weight) of each object. The force with which two objects attract each other is proportional to their mass and decreases rapidly the moment we separate them.
Explanation:
hi i'm mexican long live mexico
Answer:
the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.

Considering that cells vary in shape,what other dimensions or parameters of the cell could be used to estimate cell size?
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.
explain how a mutation could have no effect on the organism that inherits the mutation
Answer:
A mutation could have no effect on the organism that inherits the mutation because of the chances of the organism's parents/producers. One parent may be dominantly having the mutation while the other parent may have the mutation but does not display its effects, thus labeling this parent as a carrier of the trait/mutation. Drawing a punnet square would best be used to describe the possibilities of each offspring and how each carries or shows the mutation inherited from their parents.

Students were given a list of seven elements and asked to identify the four elements that are most abundant in biomolecules. Which table correctly identifies the four most-abundant elements in biomolecules?.
Answer:
Carbon, hydrogen, nitrogen, oxygen
Explanation:
Not sure what the tables are?
Biomolecules are important for living organisms and vital for cell structure and functioning. The cells are made up of biomolecules as their structural organization.
The four most abundant biomolecules are:
Carbon, Oxygen, Nitrogen and Hydrogen
The biomolecules can be explained as:
The central biomolecules for life activities are these elements that contribute to major processes.The main building blocks like carbohydrate is composed of carbon, oxygen and hydrogen. They provide energy to the body by breaking into small molecules.Proteins are vital for cell signalling and transport. They are composed of amino groups consisting of nitrogen.Therefore, carbon, nitrogen, hydrogen and oxygen are the most abundant biomolecules.

what is photosynthesis?
Photosynthesis is the process by which plants generate simple carbohydrates. This process used the energy from the sun.
Photosynthetic reactions:Photosynthesis refers to the metabolic process by which plants and algae use the energy from the sun and carbon dioxide to generate simple carbohydrates and oxygen.Photosynthetic reactions can be divided into light-dependent reactions and light-independent reactions.The light-independent reactions (also called the Calvin cycle) generate simple carbohydrates such as glucose.In conclusion, in photosynthetic reactions, plants turn carbon dioxide (CO2) and water (H2O) into simple carbohydrates by using the energy from the sun.

Hormones exert an effect only on a gland or organ that has a ________ where that specific hormone can bind.
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.
