Answer:Acid rain
Explanation:
A person eats a large meal, which makes him feel sleepy. Later, he gets indigestion and throws up. The first event involves the action of the
parasympathetic nervous system
sympathetic first and then parasympathetic nervous system
parasympathetic first and then sympathetic nervous system
sympathetic nervous system
Answer:
When the parasympathetic nervous system (PSNS) is activated, it slows our heart and breathing rates, lowers blood pressure and promotes digestion. Our body enters a state of relaxation, and this relaxation breeds recovery
Stimulating the vagus nerve stimulates the parasympathetic nervous system, which in turns reduces our neurophysiological experience of stress. It reduces our heart rate and blood pressure. It influences the limbic system in our brain, where emotions are processed.

Which type of bonds form between the oxygen and hydrogen atoms of within a water
molecule
Answer:
covalent bonds
Explanation:
Covalent bonds occur when two atoms—in this case oxygen and hydrogen—share electrons with each other. Because oxygen and hydrogen attract the shared electrons unequally, each end of the V-shaped H2O molecule adopts a slightly different charge. The area around the oxygen is somewhat negative compared to the opposite, hydrogen-containing end of the molecule, which is slightly positive.

Answer: A!
Explanation: All biological organisms play a part in the earth's ecosystem, but consumers get energy from eating other organisms and producers make energy on their own. Grass is a producer, a self-sustaining organism that obtains its energy from the sun. In the process, it introduces new organic substances into the food chain and plays a key role for consumers. Grass forms the basis of the food chain because of this ability.

In your own words, discuss the importance of enzymes within a living system and include what the function of an enzyme is. Using your best grammar, write 2-4 sentences.
Answer
Enzymes are proteins that act as biological catalysts that increase the rate if a reaction by decreasing the amount of energy needed to speed up the reaction. Enzymes help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. Enzymes build muscle, destroy toxins, and break down food particles during digestion.

What would be the best negative control to use when testing for any organic compounds
Explanation:
A similar question was asked online, here is the answer it gave:
'“Negative control” is a treatment that by definition is expected not to have any effect (neither positive effect, nor negative effect). “Positive control” is treatment with a well-known chemical that is known to produce the expected effect with the assay that you are studying. Application of an antagonist is not a negative control in your case. “Negative control” is condition that should be treated with the same solutions or buffers as your “treatment” condition, with the only difference that instead of the chemical that you investigate you should add just the solvent that was used to dissolve you chemical in the respective final concentration that you have in the “experimental treatment” condition. For example if your chemical is dissolved in DMSO – than the correct negative control will be to add to the medium/buffer just DMSO in the same final concentration that you reach with your “treatment” condition. One of the reasons of using such negative control is to verify that the solvent is having no effect in your assay. Note that among all treatment conditions (“negative control”, “positive control”, “experimental treatment you are investigating”) the volumes and the composition of the treatments that you are doing should be uniform: always treat with the same volume of medium or buffer, always containing the same concentration of the used solvent (e.g., DMSO). The only difference should be the presence or absence of the defined compound-treatments (agonist, antagonist, the chemical for the experimental investigation etc.).'
My best advice is to use the textbook you have, or use examples of a negative control when testing organic compounds because you have to find something that you can assign, like a worm in a box of dirt, the worm could have enough food to survive, so that is your negative control, but when it comes to finding the best, that would have to rely on something within the parameters of being self sufficient like a plant getting its energy from photosynthesis, etc.

why does the central part of a red blood cell appear paler than the outer part when viewed under a light microscope
Answer: The central pale area of each red blood cell is due to the concavity of the disc.
Explanation:
The absence of a nucleus and light effect makes the central part of a red blood cell appear paler
The red blood cells ( RBC )does not have a nuclei like every other cells contained in the body. therefore when viewed under a light microscope the outside of the red blood cell will appear brighter ( pink ) while the center of the red blood cell will appear pale ( whitish ). also the the light intensity from the light microscope contributes to the pale nature of the central part of the red blood cell.

use the concept of natural selection to explain why organisms typically adapt over time
Answer:
natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species
Explanation:
Answer:
Natural selection is the process by which organisms which are not as well adapted to their environment do not survive long enough to pass their less favorable traits on to the next generation of their species. Eventually, the more favorable traits are incorporated into a species as the organisms that had those traits survive while the ones who do not die. This process takes time because it occurs through individuals with the favorable traits passing those traits on to future generations. Typically, the less favorable traits will not be eradicated in one generation.

Identify two examples of foods that contain high amounts of
each of the following macromolecules: carbohydrates, lipids, and proteins.
Answer:
Carbohydrates: pasta and rice, both very starchy
Lipids: beef and bacon, both have animal fat in themm which contains lipids
proteins: eggs and beef, lots of animal derived foods contain proteins since thy are the basis of life.
Explanation:
Here are two examples for each of the three macromolecules; Carbohydrates; Bread, Rice. Lipids (Fats); Avocado, Salmon. Proteins; Chicken Breast, and Beans.
Carbohydrates;
Bread; Bread is rich in carbohydrates, primarily in the form of starch. It provides a quick source of energy due to its high carbohydrate content.
Rice; Rice, especially white rice, is another significant source of carbohydrates. It is a staple food in many cultures and contributes to daily energy intake.
Lipids (Fats);
Avocado; Avocado is a fruit that contains healthy monounsaturated fats. It is often used in salads, spreads, and various dishes.
Salmon; Salmon is a fatty fish that provides omega-3 fatty acids, which are essential for heart and brain health.
Proteins;
Chicken Breast; Chicken breast is a lean source of protein, low in fat. It is commonly consumed for its high-quality protein content.
Beans; Legumes such as beans (e.g., kidney beans, black beans) are rich in plant-based proteins. They are a staple in many vegetarian as well as vegan diets.

d. nucleic acids
Answer:
c. lipidsExplanation:
As,
A lipid is a phospholipid, a major structural component of all cell membranes. It is composed of a glycerol molecule, two fatty acids
The type of biomolecule that is made up of fatty acids is Lipids and thus, option C is the correct answer.
Nucleic acids, Lipids, Proteins, and Carbohydrates, are some of the significant biomolecules. The characteristics of lipids are listed as follows:
The organic molecule that is specifically related to fatty acids and can be able to dissolve only in organic solvents and not in water are called lipids. The lipid molecule is composed of 1 molecule of glycerol and 3 molecules of fatty acids that are linked to one another. Oils, waxes, fats are some examples of lipid molecules.Thus, we can conclude that lipids are the type of biomolecules which is made up of fatty acids.
