Which of the above phrases describes the blood pressure reading taken while the heart is beating?

Hyperstolic

Hyperbolic

Diastolic

Systolic

When the heart beats faster than when it relaxes, blood pressure rises. The higher figure, known as the systolic pressure, is your blood pressure while your heart is contracting and is the second number you are given when your blood pressure is taken. When the heart has relaxed, your blood pressure, or diastolic blood pressure, is the lower value. These numbers provide a crucial indicator of cardiovascular health when taken as a whole.

Methanogens are certain archaeans. Swamps, cows’ guts, and even human colons are home to certain methanogens. What gas does methanogen metabolism result in the emission of?

Carbon monoxide

Hydrogen sulfide

Ozone

Methane

Methanogens produce methane, as the name suggests.

Chestnut blight, a form of ____ infection, nearly led to the demise of the American chestnut.

archaean

bacterial

viral

The American chestnut is on the verge of extinction due to chestnut blight. The species is still being saved by ongoing efforts. These attempts involve developing American chestnut strains that are blight resistant.

Phlebitis was a problem for my grandma. Describe phlebitis.

Inflammation of the arteries

Inflammation of the capillaries

Inflammation of the veins

Ballooning of a region of an artery

Inflammation of the veins

When you have a cold, why does food taste bland?

Much of what we perceive as taste is actually smell.

The lack of desire to eat when ill causes food to taste bad.

A cold increases the rate at which taste buds die and replacement taste buds are formed at a slower than usual rate.

A cold causes taste receptors to malfunction.

Much of what we perceive as taste is actually smell.

A cold-related stuffy nose restricts the olfactory receptors in the nose, which dulls the flavor of food.

LSD originated from a(n) _____

fungus

bacterium

plant

animal

The original source of LSD was ergot, a fungus that grows on grains.

Nonvascular plants have a flagellum in their sperm. As a result, their sperm reach the egg by _____

being blown there in the air

being pollinated by bees

swimming in water

crawling along the ground

swimming in water

Flagellated sperm swim to the egg. This is one of the reasons why most plants, including mosses, are restricted to damp settings.

A(n) ____ is used to evaluate the heart’s electrical activity.

EEG

EKG

EGG

ABC

EKG

Electrocardiogram, often known as EKG or ECG. Any abnormalities seen by an EKG might indicate an issue with cardiac function.

Compared to other cell types, archaeans resemble ____ cells more.

fungal

animal

bacterial

plant

tube feet

wings

tube feet

A theory and a hypothesis are different terms for the same thing.

A theory is a fact; a hypothesis is a comprehensive explanation.

A theory is a comprehensive explanation of a phenomenon; a hypothesis is a generalized statement that can be used to generate testable predictions.

In the body, ____ blood arteries serve as the conduits for the exchange of oxygen and carbon dioxide.

capillaries

distributing arteries

venules

arterioles

capillaries

Capillaries are just one cell layer thick, which facilitates the interchange of materials more easily than if the vessels were made of many cell layers.

Describe leukemia.

Cancer of blood cell producing tissue

A low white blood cell count

A low platelet count

A high red blood cell count

Cancer of blood cell producing tissue

White blood cells are produced in great quantities as a result of leukemia. Due to the immaturity of these white blood cells, this both decreases the formation of other blood cell types and weakens immune system performance.
