Which of these molecules is an important source of ENERGY for most organisms?
Nitella [24]

Answer:

Glucose

Explanation:

Glucose molecule is the primary source of energy for most organisms where processes such as glycolysis starts and cellular respiration follows. Bodies of organisms can get energy from carbohydrates, proteins and fats with carbohydrates being the main component for energy where they are converted to glucose which is a form of sugar that reacts to affect blood sugar levels within an hour or two hours after eating.

The second answer option, table salt (NaCl) is incorrect because sodium added in food is vital for functioning of nerves and muscles. Additionally, it helps in fluid regulation and control of blood pressure/volume in the body.

The third answer , hydrochloric acid is not correct because presence of hydrochloric acid in the body helps in breaking down, digestion and absorption of nutrients.

The correct answer choices are : A and D.

How does wind cause weathering?
pantera1 [17]

Hello!! WOW, what a coincidence! I just took this lesson and quiz yesterday, so the answer is still fresh in my mind!

The answer to your question is

D) Blowing sand can wear away a rock's surface and break it into smaller pieces

When wind blows, sure it can pick up dry soil and sand and relocate it, but that doesn't cause the weathering in rocks.

Wind doesn't create new landforms either, that comes from plate tectonic movements and other things.

I just eliminated B and C with the two sentences above, I really don't know how to eliminate A, just common sense i guess.

Please give me brainliest if I was correct and helpful!

Otherwise, please comment and let me know how I can fix my answer!

Thank you, it was fun, have a nice week!

slader An experiment is carried out where 13.9 g of solid NaOH is dissolved in 250.0 g of water in a coffee-cup calorimeter. Dis
kvv77 [185]

Answer:

The mass of the surrounding is M_t = 263.9 \ g

Explanation:

From the question we are told that

      The mass of  NaOH is  m = 13.9 \ g

      The mass of water is m_w = 250.0g

      The chemical equation for the dissociation process is

       NaOH _{(s) } ---> Na^{+}_{(aq)} + OH^{-} _{(aq)}

       The specific heat capacity of the mixture is c_p = 4.18 J g^{-1} C^{-1}

       

The combined mass of the solution is

         M_t = 13 + 250

         M_t = 263.9 \ g

The mass of the surround here is the mass of the coffee-cup calorimeter and this contain the mixture ( water and the NaOH ) so the mass of the surrounding is  

  M_t = 263.9 \ g
