Charles is an engineer who is evaluating a prototype of an artificial heart. The prototype beats in a synchronized fashion, is hollow, and had tubes attached to it. It can be powered by electrical signals from the brain when it is interfaced with the appropriate nerves. What important feature should Charles notice the prototype is missing ?

Answers

Answer 1
Answer: The prototype is missing a speed control mechanism. A natural heart can adjust the rate at which it pumps blood around the body - for example, it beats quicker during exercise. As such, the artificial heart needs a monitor that regulates how fast the blood needs to be pumped around the body to maintain a sufficient supply to muscles.

Answers

The circle part of the structure is the CARBOXYL PART.

Generally, lipids are naturally occurring molecules and they serve as sources of high energy value in humans. Basically, lipids are synthesized from glycerol and fatty acids. The number of fatty acids attached to the glycerol determine the type of lipid that the molecule is. The glycerol is a type of alcohol and is made up of hydroxyl ions. lipid bio molecules are soluble in non polar solvent and insoluble in water.

Answer:

CARBOXYL PART.

Which lunar phase comes directly before the full Moon phase?

Answers

The Waxing Gibbous comes before the full moon stage.
The moon cycle is:
New Moon > Waxing Crescent > First Quarter > Waxing Gibbous > Full Moon > Waning Gibbous > Third/Last Quarter > Waning Crescent > Then back to New Moon and the cycle starts again.

Hope this helps! ^.^

Final answer:

The Waxing Gibbous phase directly precedes the Full Moon phase. In this phase, more than half the moon is illuminated but not entirely. It's this phase where the moon grows closer to becoming a full moon.

Explanation:

The lunar phase that directly precedes the Full Moon phase is known as the Waxing Gibbous phase. Here, more than half the moon is illuminated but it isn't fully illuminated just yet. It is in the Waxing Gibbous phase that the moon grows closer to becoming a full moon, as 'waxing' means 'growing' or 'increasing'

For instance, imagine the Moon moving around the Earth from right to left. As it moves in its orbit, we begin to see more and more of the Moon illuminated from our view on Earth. Once it surpasses the half illumination point, this is when we call the lunar phase 'Waxing Gibbous' right up until it becomes a Full Moon.
