30. An anatomist wishes to make detailed comparisons of

medial surfaces of the left and right sides of the brain. This

work requires sections that show the entire medial surface.

Which kind of sections should be ordered from the lab for

this investigation?

Answers

Answer and Explanation: In anatomy, bodies are divided by hypothetical geometric planes to describe location or direction of its structures. These planes are called Planes There are 3 reference planes:

1) Sagittal Plane divides the body into sinister and dexter (left and right) sides.

2) Coronal Plane divides into anterior and posterior portions.

3) Transverse Plane divides into superior and inferior portions.

For the anatomist, to have a section that shows the entire medial surface, should be ordered the Sagittal Plane, more especifically midsagittal (median) plane.

What cause the slight positive (8+) and negative (8-) poles on a molecule of H20?

Answers

Answer:

In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms

Because of the water molecule's bent shape and its atoms' unequal sharing of electrons, it has partial positive (δ+) and partial negative (δ-) poles. ... A hydrogen bond occurs when molecules that have hydrogen covalently bonded to oxygen, nitrogen or fluorine interact.

Explanation:

Water is said to be a molecule made of oxygen and hydrogen atoms. There is a partial negative and positive charge at the poles of water due to hydrogen bonds, and electronegativity.

What are hydrogen bonds?

Hydrogen bonds are defined as weak chemical bonds and interactions that result from the electrostatic attraction between the electronegative atom and the proton. These bonds are formed by dipole-dipole interactions.

Oxygen atoms in the water molecule are highly electronegative whereas the hydrogen atom of the water molecules is proton donors. This results in the formation of hydrogen bonds between the oxygen atom of one molecule and the hydrogen atom of the other molecules.

The electron sharing between the hydrogen and the oxygen atom tends to be unequal resulting in bonds being slightly towards the oxygen atom due to its electronegative nature. This results in the formation of partial positive and negative charges.

Therefore, hydrogen bonding results in slight positive and negative charges.

C) display each of the four key characteristics of the chordates at some point in the life cycle
D) possess a backbone in at least one life stage.

Answers

Answer:

C) display each of the four key characteristics of the chordates at some point in the life cycle

Explanation:

To be characterized as a chordate, an organism must display each of the four key characteristics of the chordates at some point in the life cycle. Therefore, the correct option is C.

To be characterized as a chordate, an organism must display four key characteristics at some point in its life cycle.

These characteristics include having a notochord (a flexible rod-like structure), a dorsal hollow nerve cord, pharyngeal slits or pouches, and a tail.

It is not necessary for all four characteristics to be present simultaneously or in both the larval and adult stages. As long as the organism exhibits these characteristics at some stage of its life, it can be classified as a chordate.

Each enzyme can catalyze many different biochemical reactions. D. Enzymes and substrates fit together like a lock and key.

Answers

It would be answer D. because enzymes are a type of catalysts that function in living things and a substrate is a reactant that an enzyme catalyzes. An enzyme and substrate fit together perfectly like a lock and key as it catalyzes and produces a product

Enzymes are proteins that are like keys and fit into the lock called substrate to carry out the reactions. Thus, option D is accurate.

What are enzymes?

Enzymes are involved in metabolic reactions and act as catalysts by speeding up the reactions. They do not decrease the activity function of the rate of reactions in the living things.

A specific type of enzyme can catalyst only a single type of substrate and are unique for a reaction. Enzymes and substrates act as lock and key that fits together to carry out the reaction.

The active site of the enzymes is unique and fits into the substrate to form the complex resulting in a product formation.

What is the appropriate protein portion for men?
A. 2 palm portions
B. 3 palm portions
C. 2 cupped handfuls
D. 3 cupped handfuls

Answers

Answer:

A is correct- 2 palm portions is an appropriate protein portion for men

Explanation:

Two palm portions is the appropriate protein portion needed for men. It is advised to consume 0.8 grams of fat per kilogram of body weight. So, option A is right.

Amino acids are the building blocks of proteins. Your body requires amino acids to create hormones and enzymes, as well as to build and repair muscles and bones. They can also be utilized as a source of energy.

For a typical sedentary adult, the suggested dietary allowance is 0.8 grams per kilogram of body weight.

For men, 2 palm sized portions of protein is recommended in each meal. Palm is used to measure protein and handfuls is used to measure carbohydrates.

30 grams of protein are contained in one palm serving. Two palm pieces would therefore provide roughly 60 grams of protein for a man having 50-70 kilogram, which is a sufficient quantity for most guys.

Therefore, option A, 2 palm portions of protein is the appropriate protein portion for men is the correct answer.

Answers

Answer:

B. The 55 N cat has less mass than the 110 N dog.

Explanation:

Weight of an object refers to the product of its mass and the force of gravity. However, the greater that mass of an object, the greater the weight of that object.

In this case, the cat's weight is 55N while the dog's weight is 110N. This means that the dog has a greater mass than the cat or alternatively put, the 55 N cat has less mass than the 110 N dog.

Note that: if the gravitational effect is removed, the cat will contain lesser mass.

Explanation:

Phenytoin (sodium channel blocker) and ethosuximide (calcium channel blocker) are anti-seizure drugs that stop seizures from happening. These drugs work by inhibiting electrical impulses (action potentials) from occurring. Explain the importance of sodium and calcium channels on a neuron and and the reasons why action potentials do not occur when these channels are inhibited

Answers

Answer:

Phenytoin and ethosuximide are drugs that slow the recovery of the sodium channel during the inactivated state.

That is to say, they prolong the inactivation state of the channel, thus generating that in this way the neuron remains in resting potential and the action potential causing the epileptic attack is not triggered.

On the other hand, these drugs, according to the bibliography of the book "Golan, 3rd Edition, Principles of Pharmacology" have a use-dependent affect capacity, this means that those sodium channels that have more activity will be more affected, in this way Not only is epileptic shock avoided, but if the same happens independently in any neuron, it will not be able to propagate the action potential to its neighboring neurons, therefore the surrounding neurons will not be stimulated and will not be fulfilled. with the sudden rapid discharges that are the most dangerous in some cases of severe epilepsy.

It is important to understand that these drugs affect the ion channels responsible for exciting neurons, that is why by inhibiting them, a constant rest of these neurons is promoted, and they are unable to generate abrupt discharges and dissemination of the electric charge. among them generating epileptic shocks.

The ions in neurons are in charge of indicating or modulating the different neuronal states, if they are inactive, open or closed, they will directly affect the membrane potential, that is, the positive or negative charge of the neuron's membrane.

Explanation:

In order to finish completing the question, these drugs are excreted through the p450 protein, that is why if this excretion system becomes saturated because another drug is consumed that is excreted in the same way, these antiepileptics will remain longer in use. blood and in the body, generating a greater effect and enhancing adverse effects on the central nervous system.

From the memoir of author Abigail Prynne1I sit at my desk listening to thunder growl outside my window. Flashes of light burst through the darkness, and wind races past my window. The thrilling combination of sight and sound conjures up visions of dragons roaring proudly, breathing fire, and soaring across the midnight sky. Dragons first fascinated me when I was a little girl. They have followed me ever since. The magnificent creatures appeared in storybooks I read in the library, paintings I saw in museums, movies I watched in the theater, and the dreams I had in my sleep. By the time I was thirteen, one question consumed me. I wanted to know if dragons ever existed, so I set out on a quest for facts.2As I started my research, I discovered many skeptics. Scientists presented evidence to show why dragons could notand did notexist. They explained that it would be impossible for dragons to fly because they would be too big. They laughed at the idea of dragons breathing fire. They pointed out that no other animal has ever done this. They said that if dragons had lived, someone would have found remains somewhere in the world. No bones about it, there were plenty of logical explanations. It would have been easy for me to accept that the only place dragons ever existed was in the imaginations of those who believed.3I could have given up, but I thought about my grandmother. She always told me that "people who believe that science is the answer to everything are missing out on everything else." With her words in mind, I searched some more. There were many facts that hinted that dragons may not be fictional. I noticed that cultures across the world all described dragons in similar ways. This was odd because they had no way to communicate with each other. I found dragons mentioned in more than just stories. They appeared in old legal papers, in the travel logs of Marco Polo, and in the Bible. I saw that the Chinese calendar uses a different animal each year. Dragons are included along with eleven real animals. I began to believe it was a real possibility that all of these people were talking about a creature that actually existed.4With renewed hope that there was some truth to the legends, I looked for new research. I found that some experts disagreed with popular arguments against dragons. They suggested that a dragon could have four stomachs like a cow. If it created stomach gases like birds, it might create enough to lift itself off the ground. This would give it the ability to fly. If it forced out air when diving toward the earth, it might release gases which could ignite into flame. When the animal died, the stomachs would release strong acids that would dissolve its dead body over time. Biologists backed up these ideas with sketches and models based on known animals. Not everyone agreed with these ideas, but many of the things we accept about dinosaurs and other extinct species started the same way.5I doubt we will ever truly know whether dragons existed. There may always be two sides to the fiery debate. Some will say the stories come from active imaginations. Some will believe with all their hearts that the legendary creatures roamed our ancient world. I don't know for certain which side to believe, but the sound and fury of a night like this makes me smile. It rekindles my childhood dreams and keeps the exciting possibility alive.In paragraph 5, the author discusses two sides to the dragon debate. Which statement best summarizes the ideas in the paragraph? The author implicitly states that she believes that dragons once existed. The author explicitly states that she believes that dragons once existed. The author implicitly states that she believes that dragons did not exist.
