Answer:
Neck injury, and back injury
Answer:
The stomach, gallbladder, and pancreas work together as a team to perform the majority of the digestion of food. Food entering the stomach from the esophagus has been minimally processed — it has been physically digested by chewing and moistened by saliva, but is chemically almost identical to unchewed food
Because if they aren't properly included, it means that you are saying that the numbers can be anything, all reals.
Not including units is the same thing, if you don't properly lable the data table, you could be talking about anything.
Not giving a proper unit/variable is almost like giving someone permission to assume what you're talking about
Answer:
Phenol red indicator.
Explanation:
- Phenol red indicator is an organic dye which works as an indicator in the pH range (6.8 - 8.4) for acid-base reactions.
<em>The color in acidic solutions is yellow and in basic solution is red.</em>
The half-life of polonium-210, given that it decays from 98.3 micrograms to 12.3 micrograms in 414 days is 138 days
<h3>How to determine the number of half-lives </h3>
- Original amount (N₀) = 98.3 micrograms
- Amount remaining (N) = 12.3 micrograms
- Number of half-lives (n) =?
2ⁿ = N₀ / N
2ⁿ = 98.3 / 12.3
2ⁿ = 8
2ⁿ = 2³
n = 3
<h3>How to determine the half life </h3>
- Number of half-lives (n) = 3
- Time (t) = 414 days
- Half-life (t½) = ?
t½ = t / n
t½ = 414 / 3
t½ = 138 days
