B-it does. It demonstrate the ability to move in response to environmental stimuli
Then the resultant solution is basic.
<h3>What is basic solution?</h3>
An aqueous solution that has more OH-ions than H+ions is referred to be a basic solution. It is an aqueous solution with a pH higher than 7, in other words. Ions are present in basic solutions, which also conduct electricity, color blue on red litmus paper and are slick to the touch.
The scale ranges from zero (the most acidic) to fourteen (the most basic). Pure water has a pH value of 7, as can be seen from the pH scale above. Since it is neither acidic nor basic, this value is thought to be neutral.
Potassium hydroxide (KOH), Sodium hydroxide (NaOH), Caesium hydroxide (CsOH), Strontium hydroxide (Sr(OH)2), and Lithium hydroxide are some typical strong Arrhenius bases.

Answer:
0.492 J/g °C
General Formulas and Concepts:
<u>Thermodynamics</u>
Specific Heat Formula: q = mcΔT
- <em>q</em> is heat (in J0
- <em>m</em> is mass (in g)
- <em>c</em> is specific heat (in J/g °C)
- <em>ΔT</em> is change in temperature (in °C)
Explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
[Given] <em>q</em> = 45.0 J
[Given] <em>m</em> = 8.10 g
[Given] <em>ΔT</em> = 24.3 °C - 13.0 °C = 11.3 °C
[Solve] <em>c</em>
<em />
<u>Step 2: Solve for </u><em><u>c</u></em>
- Substitute in variables [Specific Heat Formula]: 45.0 J = (8.10 g)c(11.3 °C)
- Multiply: 45.0 J = (91.53 g °C)c
- Isolate <em>c</em>: 0.491642 J/g °C = c
- Rewrite: c = 0.491642 J/g °C
<u>Step 3: Check</u>
<em>Follow sig fig rules and round. We are given 3 sig figs.</em>
0.491642 J/g °C ≈ 0.492 J/g °C
Answer:
D. An endangered species is in danger of becoming extinct in the near future. A threatened species could become endangered in the near future.
Explanation:
The answer is B, since petroleum is from where plastic comes from.
