ANSWER: None of the above options are correct.

Cardiac Output(CO) = Stroke Volume(SV) × Heart Rate(HR)

Therefore where HR= 90bpm and SV= 110ml/min,

CO = 90 × 110 = 9900ml/min or 9.9L/min.

EXPLANATION:

CARDIAC OUTPUT is the volume of blood being pumped by the heart into the systemic circulation per minute.

Cardiac output is the product of two variables, stroke volume and heart rate.

STROKE VOLUME is the amount of blood pumped out by the left ventricle in each contraction.

HEART RATE is the count of the number of times the heart beats per minute.

Compare the processes by which a car and a human use "fuel" to perform work. What are the similarities?
Alenkinab [10]

A car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

<h3>What is energy?</h3>

Energy is the capacity of doing work. In physics, there exist different types of energy; among which are follows:

  • Kinetic energy: Kinetic energy can simply be defined as that energy a body posses due to its motion
  • Potential energy: , On the other hand, potential energy is the energy a body has due to its relative position.

Other forms of energy include:

  • Solar energy
  • Nuclear energy
  • Mechanical energy

So therefore, a car needs to be fueled before it can set in motion to posses a given amount of kinetic energy.

Therefore, kinetic energy is the energy which allows a car to be fueled before it can set in motion .

Many soil-dwelling bacteria produce molecules that can be naturally synthesized and kill other species of bacteria. What are these bacteria-killing molecules called antibiotics

Antibiotics are effective pills which can be usually safe. Although they are very helpful in fighting disease,  antibiotics can actually be harmful. Important Facts About Antibiotic Safety: Antibiotics can cause side effects such as allergic reactions and severe and potentially life-threatening diarrhea caused by the bacterium Clostridium difficile (C. diff).

Antibiotics can also interfere with other medications you may be taking. Antibiotic side effects account for nearly one-fifth of  emergency room visits. These conditions are the most common reasons for emergency room visits for children under the age of 18. Taking antibiotics you don't need unnecessarily exposes you  to the drug's side effects and denies you the benefits.

Basile [38]
This definition above refers to the geographic isolation.
It means exactly what it says in the definition - one species is left behind from the rest of the population, and it stays in that particular location, evolving and changing from the species and population it was once a part of.
