Answer:
Mammals do not have instincts, so they must learn all their behaviors from their parents in order to survive.
Sea turtles must survive on their own, while mammals spend time with their parents and learn how to survive as they grow.
Sea turtles are less intelligent than mammals and, thus, cannot learn new behaviors from their parents.
Explanation:
Not very often, but sometimes, the language gives away the question. This is one such instance.
Look at A. Is digestion a bad thing? It shouldn't be. Otherwise you run marathons with gobs of food not being broken down and providing energy.
Not A.
Not C. Do you like yogurt? If you don't do you know someone who does? Is yogurt for you/them a bad thing. Bacteria here are good. Again, not C.
Not D. Waste is bad. It's a problem. Getting rid of it is good. Again not D.
There's only one left.
B <<<< answer. Who would like to get strep throat. It's a fate for your worst enemy.
B <<<< answer.
Answer:
wave length=speed/frequency
=345/229
Answer:
OH⁻
Explanation:
A base is defined as a substance which interacts with water to yield excess hydroxide ions, OH⁻, in an aqeous solution.
Examples are Sodium hydroxide (NaOH)
Potassium hydroxide (KOH)
Bases are generally certain metallic oxides, metallic hydroxides and aqueous ammonia.
An acid is a proton donor, H⁺ and it interacts with water to produce excess hydroxonium ions in an aqueous solution.
Answer:
1) Add more sulfate ions.
2) 1 M K₂SO₄.
Explanation:
<em>1) Which of the following actions would shift this reaction toward solid barium sulfate?</em>
<em></em>
- Le Châtelier's principle states that if a stress is applied to a system at equilibrium, the system will shift to relieve that stress and attain the equilibrium again.
Add more sulfate ions will increase the concentration of the products side, so the reaction will be shifted towards the reactants side to relieve the stress and attain the equilibrium again.
<em>So, the right choice is: Add more sulfate ions.</em>
<em></em>
<em>2) In which of the following would barium sulfate be least soluble? </em>
The answer is 1 M K₂SO₄, it has a common ion effect of SO₄⁻ ions that increase the concentration of the products side, so the reaction will be shifted towards the reactants side to relieve the stress and attain the equilibrium again.
<em>So, the solubility will decrease.</em>
