Answers

Answer 1

Answer:

Microscope

Explanation:

The first microscopes enabled scientists to closely visualise the structure of different organisms and tissues.

The microscope was necessary to provide visual confirmation that cells exist as single units.

Why does one person's body return to the resting heart rate faster than another persons? Explain why there is a difference. (Use Vocabulary: heart, circulatory system, pump, oxygen, arteries, veins, muscles, lungs, respiratory system.)

Answers

The heart is a pump, usually beating about 60 to 100 times per minute. With each heartbeat, the heart sends blood throughout our bodies, carrying oxygen to every cell. After delivering the oxygen, the blood returns to the heart. The heart then sends the blood to the lungs to pick up more oxygen. This cycle repeats over and over again.

What Does the Circulatory System Do?
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart.

The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. These roadways travel in one direction only, to keep things going where they should.

What Are the Parts of the Heart?
The heart has four chambers — two on top and two on bottom:

The two bottom chambers are the right ventricle and the left ventricle. These pump blood out of the heart. A wall called the interventricular septum is between the two ventricles.
The two top chambers are the right atrium and the left atrium. They receive the blood entering the heart. A wall called the interatrial septum is between the atria. The atria are separated from the ventricles by the atrioventricular valves:

The tricuspid valve separates the right atrium from the right ventricle.
The mitral valve separates the left atrium from the left ventricle.
Two valves also separate the ventricles from the large blood vessels that carry blood leaving the heart:

The pulmonic valve is between the right ventricle and the pulmonary artery, which carries blood to the lungs.
The aortic valve is between the left ventricle and the aorta, which carries blood to the body.
What Are the Parts of the Circulatory System?
Two pathways come from the heart:

The pulmonary circulation is a short loop from the heart to the lungs and back again.
The systemic circulation carries blood from the heart to all the other parts of the body and back again.
In pulmonary circulation:

The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.

2. Oxycodone: brand name Xtampza ER

CNS depressants for anxiety and panic disorders:

1. Triazolam: brand name Halcion

2. Etizolam: brand name Etilaam

Stimulants for increased production of dopamine and norepinephrine to help with attention deficit disorders:

1. Amphetamine: brand name Adzenys

2. Dextroamphetamine: brand name Dexedrine

I hope this is all you needed! The things in bold are the classifications of prescribed drugs and their uses, and then the stuff below that is the names of the most common drugs in those categories and their brand names. Happy learning, friend! :)

Answer:

Drugs can be classified in many different ways. Some drugs are classified according to their level of control (i.e., the addiction potential of the drug).. On the one hand, there are drugs that you cannot buy without a doctor’s prescription, and on the other, there are drugs that can be easily bought over the counter at a drug store. Another type of classification is the one used by the US Food and Drug Administration (FDA). The most widely-used system is the Anatomical Therapeutic Chemical Classification System (ATC system).

Three commonly prescribed drug classes are β-receptor blockers (beta blockers), lipid regulators, and antidepressants. Here are the classes and their two respective brands:

Bete Blockers

Brevibloc (esmolol): This medication is used in hospital settings, where the patient’s vital signs can be monitored. It can help treat increased blood pressure, rapid heart action, and hypertension. It is either injected or administered by intravenous infusion.

Sectral (acebutolol): Sectral is used to treat high blood pressure, irregular heartbeat, and for preventing strokes. It comes in the form of capsules, at one of two dosage strengths (200 or 400 mg). Initially, a dose of 400 mg is taken once a day or divided into 2 doses. If necessary, the dosage can be increased to 800 mg per day.

Lipid Regulators

Lipitor (atorvastatin calcium): It is used to reduce bad cholesterol and increase good cholesterol. It helps in the treatment of high cholesterol, stroke, and heart disease. It comes in the form of 10 or 20 mg tablets that are taken once a day.

Mevacor (lovastatin): It is used to lower bad cholesterol and increase good cholesterol. It comes as a tablet of 10, 20, or 40 mg, which is taken once a day. The highest recommended dose is 80 mg a day.

Antidepressants

Prozac (fluoxetine): It is used to treat depression, panic attacks, obsessive compulsive disorder, and bulimia. It comes as a tablet of 10, 20, or 40 mg that is taken once or twice a day, according to doctor’s orders. It is also available in liquid form.

Cymbalta (duloxetine): It is used to treat depression and anxiety. It comes in the form of 20, 30, or 60 mg delayed-release capsules, taken once or twice a day depending on doctor’s orders. Going off this drug is very difficult because it is known to cause powerful and debilitating withdrawal symptoms.

When a friend gives us a dirty look, we automatically assume that he is mad at us, but he could simply be having a bad day or contemplating something that is reflected in his expression.

What is a tendency to make illusory correlations?

Illusory correlation is the phenomenon of believing there is a relationship between variables even when there isn't one, where a false association can be created because uncommon or unique events are more conspicuous and hence catch people's attention.

An illusory correlation arises when two distinct variables occur at the same time and an unsupported association is drawn with scant data.

Therefore, seeing friends' dirty looks, an illustration of this would be if someone had a poor, instead of making assumptions, we should always ask someone.
