Allen and his lab partner each held a tuning fork, frequency 440 Hz, in their hands. Allen tapped his tuning fork with a mallet

and they listened to the sound it made. "Wait a minute!" exclaimed Allen's partner. "My tuning fork is vibrating too!" Sure enough, both tuning forks were vibrating although only Allen hit his with the mallet. How can you explain this? A) Sound waves are transferred to the tuning fork. B) Sound particles caused the second tuning fork to vibrate. C) Sound energy travelled as waves from one tuning fork to the other. D) Sound energy travelled as particles from one tuning fork to the other.

Answer:

The correct answer is option C. Sound energy traveled as waves from one tuning fork to the other.  

Explanation:

Sound energy is the energy that is generated if an object vibrates. The sound is basically is the waves that travel by a medium such as water, solid and air. the solid medium is usually metal or wood. guitar is one of the great examples of the sound energy-producing object.

The sound is one of the forms of mechanical energy. In this case, sound energy is generating by the hitting tuning fork with a mallet that is transferred as waves to the other tuning fork.

Thus, the correct answer is option C.

A change in temperature affects an enzyme by causing the enzyme to change it's shape.

<h3>what is an enzyme?</h3>

An enzyme is a substance that catalyzes chemical reactions.

  • Temperature is one of the major factors that aid enzymes action.

  • Increase in temperature could increase the rate of enzyme.

  • However, at a very high temperatures, the enzyme can be denatured thereby changing it shape or structure and the enzyme may no longer bind to the substrate or function effectively this will then reduce the rate of chemical reaction.

Therefore, a change in temperature i.e very high temperature can change the shape of an enzyme.

1) The process arrow A represents is photosynthesis.

2) Arrow A represents light energy transformation. Light energy from the sun is converted into chemical energy in plants.

3) Photosynthesis is part of a carbon recycling process in the carbon cycle. Plants absorb light energy and convert it to chemical energy. Plants absorb carbon dioxide which is exhaled by humans and animals. Plants then produce oxygen which is absorbed by humans and animals. Animals also eat plants thus passing the carbon compounds along.

I hope this makes sense. Hope this helps! :)

For a particular species of wolf, 55% are female, 20% hunt in medium-sized packs, and 15% are both female and hunt in medium-siz
lorasvet [3.4K]
*Given
Percent of the wolves which are female - 55%
Percent of the wolves which hunt 
     in medium-sized packs                      - 20%
Percent of the wolves which are both
     female and hunt in medium-sized
     packs                                                  - 15%


*Solution

<u>Assuming that there is a total of one hundred wolves in the species, </u>

1. Since percent (%) means "per 100" or "for every 100" then, 

a. The number of female wolves is

    (55 female wolves / 100 wolves) * 100 wolves total = 55 female wolves

b. The number of wolves that hunt in medium-sized packs is

    (20 wolves / 100 wolves) * 100 wolves total = 20 wolves

    Note that the 20 wolves is a mixture of male and female wolves. 

c. The number of female wolves that hunt in medium-sized packs is

    (15 female wolves / 100 wolves) * 100 wolves total = 15 female wolves

2. Because there is a total of 55 female wolves in the species, and 15 of these wolves hunt in medium-sized packs, then the number of female wolves that do not hunt in medium-sized packs is, 
 
    55 female wolves total - 15 female wolves hunting  = 40 female wolves not
                                                in medium-sized packs         hunting in medium
                                                                                              sized packs

3. To find the proportion, we can express the answer in terms of percent (%) or in fraction, which is usually how proportions are expressed. 

For every 100 wolves, there are 40 female wolves that do not hunt in medium-sized packs. This can be expressed as a proportion of 
 
                                       <span> <u> 40  </u>
</span>                                        100

and simplified by dividing both the numerator and denominator by 10, we get,

                                     <span><u> 40/10  </u>
</span>                                     100/10

                                       <span><u>  4   </u>
</span>                                        10

When this is expressed in percent, we multiply the fraction or proportion by 100% to get, 

                                       <span><u>  4   </u>   x    100%     = 40%
</span>                                        10

Thus, the proportion of female wolves that do not hunt in medium sized packs is 4/10 or 0.4. When expressed as percent, this is 40%.
