Biois My Answer Correct ?

Answers

Answer 1
No, the option you chose is wrong. Salad dressing is a suspension & the oil & the particles gets settled when left undisturbed (2nd option.) Oil & water (the other particles) are immiscible, so it's a suspension. Some salad dressings can be a colloid as well. But, the 2nd option suits better here.Your answer is wrong because in a suspension, the particles are big & aren't informally distributed throughout the mixture. That's only in a solution/colloid. Suspensions have particles that are unevenly distributed & are big enough to scatter light until they settle down (Tyndall effect).

Homeostatis is the process by which the body maintains a stable internal environment. The hypothalamus is a part of the brain that regulates many key body processes. It works to restore the system to its normal state when an internal change in one of these systems occurs.

Long paragraph:

The hypothalamus is a part of the brain that regulates many key body processes including internal body temperature, hunger, thirst, blood pressure, and daily (circadian) rhythms. When the brain receives signals from the body about an internal change in one of its systems, it works to restore the system to its normal state. For example, the normal internal temperature for the human body is approximately 98.6 degrees Fahrenheit. If the body temperature rises because of exercise, the body will try and cool itself off. This happens through coordination between the hypothalamus and the various body systems that are affected.

nerve fibers are insulated from one another by __________.

Answers

Answer:

endoneurium

Explanation:

The endoneurium is a layer of connective tissue composed of endoneurial cells that surround and protect the myelin sheath of each myelinated nerve fiber.

nerve fibers are insulated from one another by endoneurium.

What are nerve fibers and their composition?

A nerve fiber is a long axon from a nerve cell (neuron muscle). The body of the nerve cell is anatomically located either inside the ganglia of the peripheral nervous system or within the central nervous system.

The ganglionic neurons' axons that travel from the retina's vitreal surface to the optic disc make up the nerve fiber layer. These axons are not myelinated until they reach the optic disc and break through the sclera. The optic disc's white color is a result of oligodendrocytes' myelination of them at this point. They help in the communication of two nerve fibers.

Thus, nerve fibers are insulated from one another by endoneurium.

A person who is exercising vigorously breathes more deeply and rapidly than someone who is resting. Give TWO reasons why this is necessary.

Answers

During physical exercise, more oxygen is used up and more carbon dioxide is produced leading to faster and deeper breathing.

Physical exercise is a state in which the muscles are flexed much vigorously leading to a faster heartbeat owing to a quicker rate of pumping of the blood by the heart.

There are two main reasons why a person engaging in physical exercise tends to breathe faster and more deeply;

The muscles tend to work harder during physical exercise hence more carbon dioxide is produced.The body uses up oxygen more quickly leading to a greater demand for oxygen and thus a faster and heavier breathing rate results.

what can be said about altitude, atmospheric pressure, and the partial pressure of oxygen? check all that apply.

Answers

As both altitude and atmospheric pressure increase, the partial pressure of O2 will decrease.

Though I could not locate the options online to provide an exact answer, I can offer a general overview of the question at hand.

The interactions between altitude and the partial pressure of oxygen are inversely proportional. This means that as one increases, the other will decrease. The proportion of oxygen is 21% of the air content at all altitudes. However, as the altitude increases, the atmosphere becomes thinner, meaning that the partial pressure of O2 will decrease given that 21% of a thinner atmosphere results in less oxygen.

On the other hand, the relationship between atmospheric pressure and oxygen is that they are directly proportional. This means that as one decreases, the other does as well. In this case, since atmospheric pressure is the sum of the partial pressures of all gases, we can conclude that as it decreases, so to will the partial pressure of oxygen.

Kim's Dalmatian, Tigger, always eats the same brand of food. Although he does everything else at lighting speed, he is a very slow eater. After watching a TV commercial touting the irresistible taste of Puppy Yums Dog Vittles, Kim decides to conduct an experiment comparing Tigger's regular food (K-9 Crunchy Bits), Puppy Yums Dog Vittles, and a store brand that cost 1/3 as much as the advertised food. Kim gave Tigger the same quantity of each different food, on three successive evenings, and used a stopwatch to determine Tigger's dinner-time munching speed.

Answers

The experiment was intended to show that the dog will eat the tastier food advertised on TV at a faster rate than it eats its regular food.

An experiment must have an independent variable and a dependent variable. The dependent variable is the variable that is being manipulated in the experiment. The responding variable is also called the dependent variable.

In this experiment;

The independent variable is the type of dog foodThe dependent variable is the eating time of the dogThe predicted result is that the dog will eat the advertised Puppy Yums Dog Vittles faster than the other dog foodsThe control variable is the quantity of dog food given to the dog each evening.The hypothesis of the experiment is that the dog will eat the advertised tasty food faster than it eats its regular food.

Explain why a plant with a mitochondrial issue likely will not survive.​

Answers

Mitochondria are cellular organelles that are in charge of oxidative phosphorylation, which is the critical process of turning nutrients into adenosine triphosphate (ATP) molecules that power normal cell operations. At least hundreds of mitochondria are found in each neuron. Because nerve cells are postmitotic, any mitochondrial damage received will accumulate over time and produce malfunction. Cells die as a result of widespread mitochondrial damage because they can no longer create adequate energy.
