I believe your answer would be B.
Answer:
When a turtle is lying on a sunny riverbank, it’s body temperature rises and when it starts swimming in a cool river, it's body temperatures drop.
Explanation:
Cold-blooded animals, like turtles, do not have an internal feedback loop that regulates constant body temperature – as warm-blooded animals do. Their body temperatures fluctuate with that of the environment. This is why you see animals like lizards basking on rocks to raise their body temperatures. When it too hot, then they seek the shade under these rocks to lower their temperatures.

The molality of the solution = 17.93 m
<h3>Further explanation</h3>
Given
6.00 L water with 6.00 L of ethylene glycol(ρ=1.1132 g/cm³= 1.1132 kg/L)
Required
The molality
Solution
molality = mol of solute/ 1 kg solvent
mol of solute = mol of ethylene glycol
- mass of ethylene glycol :
= volume x density
= 6 L x 1.1132 kg/L
= 6.6792 kg
= 6679.2 g
- mol of ethylene glycol (MW=62.07 g/mol)
=mass : MW
=6679.2 : 62.07
=107.608
6 L water = 6 kg water(ρ= 1 kg/L)
During all chemical reactions, the mass of the products is never equal to the mass of the reactants.
- FALSE
Mass is sometimes lost in chemical reactions.
- FALSE
The Law of Conservation of Mass states that mass is not conserved.
- FALSE
