Biology

levacccp [35]3 years ago

The easiest example here is a computer/laptop... e.g. when the CD-ROM is spinning when you are perhaps playing a movie, the kinetic energy causes friction, which results in heat.  All computers need a fan to prevent them over-heating for this very reason.  Therefore heat is lost and energy is wasted.

Another example is a lightbulb.  When a light is switched on and left for a long time, the current flowing through the filament (the thin bit of wire in the bulb) causes heating (due to electron-ion collisions but you may not need to know that) so energy is wasted as thermal energy instead of light energy.

These are just a few examples but other ones you could use are tv screens, kettles, toasters, etc :)

Why is reducing caloric intake insufficient for a person to loose weight in a healthy way?
garri49 [273]

Because there are several factors that determine weight loss or gain and reducing calorific intake is just one of them (for reducing weight loss). Other factors that should be considered is exercise. Doing regular exercise ensures that the metabolic rate of the body is increased so much of the calories are burned even after intake. Having a lower metabolic rate can result to increased weight gain even with low calorie intake.

How does interphase prepare cells for mitosis
Luden [163]

Answer: During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.

jekas [21]

Answer:

Option 1, 2, 5

Explanation:

Options for the question

  1. car a and car b are both moving toward the origin.
  2. car a and car b are moving in opposite directions.
  3. car a is moving faster than car b.
  4. car a and car b started at the same location.
  5. car a and car b pass each other at the crossover  point on the graph.  time (s)

Solution -

The motion of any object is represented by  position-time In such graphs the position of an object is fixed for any starting point on the y-axis and time on the x-axis.

The slope of such curves determine the velocity of the object at all its position within the graph. The steeper the slope is, the faster the the object is moving.

Hence, the following statements are correct
