<h3>What is muscle?</h3>
Muscles are soft tissues. Numerous elastic fibers make up your muscles. There are more than 600 muscles in your body. The various muscle groups' purposes differ. You can move swiftly, as when you run or jump, or deftly, like when you thread a needle, thanks to certain muscles.
Muscles can be used to lift large things or give birth in addition to assisting with movement and pumping blood. Muscles either contract or relax to produce movement. This movement could be unconscious or intentional, that is, made voluntarily and consciously (involuntary).

Answer:
d) Change slides not less than every 30 seconds
Explanation:
a) Use several different fonts and font sizes throughout the presentation
Having different fonts and font sizes in your presentations will most likely distract your audience. Therefore, it is recommended to use same font and size throughout your presentation.
b) Present as much written material as possible on each slide
This is clearly not a good idea to put too much verbose in your presentation. The audience is less likely to focus on you if you put too much text in your slides. One should always keep the key points in the slides and explain them verbally to your audience.
c) Vary the slide background from slide to slide
This is similar to option A and might distract your audience, therefore not recommended.
d) Change slides not less than every 30 seconds
If you are changing the slides very fast then your audience might have trouble understanding or absorbing the content of your slides. Therefore, it is recommended that you should not change slides less than 30 seconds.

Answer:
\rb. To accelerate the heart rate by interfering with vagal impulses
Explanation:
Digoxin is a cardiac glycoside which has both the cardiac as well as the electric effects. The most important electrical effect includes early parasympathomimmetic responses(decrease in heart rate) which are followed by late arrhythmogenic actions. Thus the parasympathetic effects of digoxin specifically on atria and AV node results in a decrease in heart rate while atropine in given in this condition because it is a parasympatholytic drug thus it reverses the bradycardia induced by digoxin by interfering with vagal impulses and increases the heart rate .
Hence the option \rb. To accelerate the heart rate by interfering with vagal impulses is true.
