Answer and Explanation:
Skepticism refers to the questioning that an individual makes about certain information, when he suspects that this information presents deceptive and lying facts. In relation to skepticism in advertisements for diets and medicines for weight loss, it is important that the individual uses skepticism to research whether the information presented in the advertisement is true. In this case, the individual must search for scientific validation of the information presented in these advertisements, assessing whether there is evidence that the advertised product is effective.
Bacteria Growth Rate Formula:
N(t) = N(0) * ( 1 + r)^t
where, N(0) is the number of bacteria present at the beginning of the experiment, r is the growth rate, t is the time taken/ elapsed.
Substituting the numbers for N(t), N(0) and t from the given description, we get the value of r.
220 = 20*(1+r)^(24 hours)
Solving for r, we get r = 0.105074.
1 week has (7 x 24 = 168) hours in it.
Therefore, N(168 hours) = 20*(1+0.105074)^168
Which is approximately 390 millions.
Hence there will be 390 millions bacteria at the end of 1 week.
C.carry explosives, hope i helped :p
Answer:
Skeletal muscle contractions help maintain body temperature. (Ans. E)
Explanation:
Skeletal muscle contributes to maintaining temperature homeostasis in the body by producing heat. Muscle contractions require energy & produce heat as a by-product of metabolism. All types of muscles produce heat, but a large amount of Skeletal muscle found in the body, so it contributes greatly to heat production.
This is noticeable during extreme cold environment shivering produces random skeletal muscle contractions to generate heat to maintain the body temperature.
Skeletal muscle contractions pull (drag) on tendons, which are joined to the bones present in the body. If the contraction of muscles causes the muscle to shorten, the bone (present in the body) & other body part will start to move. Then the energy comes from a skeletal muscle produces heat & maintain the body temperature.
