Answer:
the answer is c, polarity of water molecules
Explanation:
Water is the universal solvent, which has high solubility. The water is tasteless, odorless, and transparent fluid.
The correct answer is:
Option C. Polarity of water molecules
Water has solvent abilities for a certain substance because::
The water molecule is made up of two atoms of hydrogen and one atom of oxygen. The composition of water molecules provides its polarity and the ability to form hydrogen bonds.The polarity of the water makes it an excellent solvent and can dissolve many polar and other substances.
Thus, the correct answer is Option C.

What did B. F. Skinner believe drove one's behaviors? (Site 1)
Answer:
Environment
Explanation:
B.F Skinner was of the belief that the environment of a person drove or influenced his behavior. His opinion was that human beings have a particular way of behaving which requires special kinds of responses and that as this goes on, humans will adapt and start behaving in a certain kind of way.
He strongly believed that because we learn things differently and in different environments, that is why there are differences in human behavior and one's environment can shape his personality.

A researcher investigates an organism found on the ocean floor. The organism is asymmetrical. It lacks a body cavity, body tissues, organs, and a nervous system. The researcher finds that the organism can fully regenerate itself if parts of its body are broken off. Into which phylum should the researcher classify the organism?
The correct answer is option A, that is, Phylum Porifera.
The species of Phylum Porifera are aquatic, that is, mostly marine. They exhibit cellular grade of the body, they are diploblastic animals with asymmetrical symmetry. They lack body cavity and exhibits a holozoic mode of nutrition with intracellular digestion.
They lack circulatory and nervous system and possess the tendency to regenerate their parts of the body. The organisms in phylum Porifera exhibits both asexual and sexual mode of reproduction.

Explanation:
The scuba diver is a living system. The scuba gear, or self-contained underwater breathing apparatus, is a system of air exchange. How are these two systems interacting? What are the inputs and outputs of these systems?
Answer:
Input is oxygen and output is carbondioxide or the movement.
Explanation:
These two systems i. e. scuba diver and scuba gear interacting with each other by giving oxygen to the individual and remove carbondioxide gas from the diver. The input of this system is oxygen that is required by the diver while the output is the carbondioxide gas produced by the diver or the movement of the diver. This scuba gear is responsible for the removal of carbondioxide gas from the system. This scuba gear enable us to stay in deep water for 60 minutes.

4. The elbow is located _________________ to the wrist.
Elbow is the joint between upper and lower arm while wrist is the joint between lower arm and hands.
So below :P
The elbow is located proximal to the wrist.
What is an elbow?The humerus, ulna, and radius are the three bones that make up the elbow, which is a hin-ged joint. The cartilage on the extremities of the bones protects them.
Because cartilage has a springy texture, joints can move smoothly against one another and can absorb trauma. Ligaments that make up the joint capsule hold the bones together.
The wrist is close to the elbow. This is so because the wrist makes the site of attachment more distant, while the elbow brings it closer.
The elbow joint is proximal to the wrist and distal to the shoulder because the humerus is longer than the radius and ulna combined. The elbow joint serves as the focal point or center in this situation.
Therefore, the elbow is located proximal to the wrist.

The ability of metabolically active tissue (e.g. muscle) to change energy sources from fat to carbohydrates (and vice versa) is termed
Answer:
The ability of metabolically active tissue (e.g. muscle) to change energy sources from fat to carbohydrates (and vice versa) is termed: Metabolic flexibility.
Explanation:
The human body primarily uses two sources of energy, glucose and fat. Glucose is found in the bloodstream and stored as glycogen in muscles and the liver, and fat in adipose tissue and in fatty acids. Metabolic flexibility is the ability of the body to alternate between the different energy substrates according to the circumstances of each moment. People with good metabolic flexibility will find it easier to use body fat and perform better physically. At lower intensity during exercise, more fat is consumed and at higher intensity, more glucose. If that high intensity is maintained, glycogen stores will be depleted. So then, how much energy is stored, how much is needed and how it will be delivered, is part of the reading that our body performs. This cellular adaptation to the requirements is known as metabolic flexibility.

Penicillium (the source of the antibiotic penicillin) is a mold that secretes a toxin that kills bacteria and other organisms. Penicillium, however, is not harmed by this toxin. This is an example of:_______
a. predator-prey.
b. commensalism.
c. mutualism.
d. amensalism.
Answer:
This is an example of amensalism (Option d).
Explanation:
The interaction between penicillium and bacteria is a typical example of amensalism.
Amensalism refers to a biological relationship established between two organisms, in which one of them avoids the growth, development, or survival of the other one. In this interaction, one of them is strongly affected by the other one, which does not seem to be affected at all. Antibiosis is referred to as amensalism interaction.
Antibiosis is the interaction in which one of the species secretes a chemical that kills the other species organism or inhibits its actions by causing severe damage. The organism that releases the toxic substance is called the inhibitor. For the inhibitor species, this relationship is neutral because it does not seem to be beneficiated or affected.
Another classic example of amensalism is those plants that secrete chemicals to damage or kill other plants that live near them. In this way, the secretory plants may live and grow with no competition.

Which is a possible mechanism for why we observe the correlation that red cars are more dangerous than other colored cars?
a. Younger people prefer red cars and have less driving experience
b. Red cars are more difficult to view in the evening and are therefore more prone to accidents in medium-light conditions
c. More sports cars are painted red and people who buy them are more risk-taking
d. All of the above
Answer:
b. Red cars are more difficult to view in the evening and are therefore more prone to accidents in medium-light conditions
Explanation:
Red colored cars are more dangerous than other colored cars because red color cars can not be seen in the evening or dark environment so that's why more accidents were observed with red color cars as compared to another color cars. Red is a vibrant color and one of the most dangerous cars colors. People sometimes confused with traffic lights, brake lights etc and accident happen.

Which of the following digestive system structures releases sodium bicarbonate into the small intestine, resulting in a change in the pH of chyme from acidic to basic? a. Gallbladder b. Appendix c. Liver d. Pancreas
Answer:
d. Pancreas
Explanation:
The digestive system structure which releases sodium bicarbonate into the small intestine, resulting in a change in the pH of chyme from acidic to basic is called the pancreas. It makes use of the pancreatic duct in releasing the bicarbonates into the small intestine.
The bicarbonates aids the digestive processes and also neutralizes the duodenum from acidity. This is due to the the acidic food from the stomach and is as a result of the stomach being acidic and having acids such as dil. Hcl.
The system that breaks food molecules into smaller pieces and components for absorption and excretion is called the digestive system. It includes organs and secretions required for digesting liquids and food.
The digestive system that releases sodium bicarbonate is:
Option d. Pancreas
The system can be explained as:
The pancreas is an organ that releases sodium bicarbonate and enzymes rich in pancreatic juices to send them to the small intestine through ducts.The acidic chyme produced in the stomach gets passed to the small intestine where the pancreatic secretion along with sodium bicarbonate buffers the acidic juices and inactivates the enzyme pepsin which changes the pH of chyme to basic.The bicarbonate salt neutralizes the acidic nature of chyme and protects the further digestive organs from acidic food.Therefore, the pancreas secretes sodium bicarbonate.
