Look to be honest, I don't know how to work out the problem, but my teacher, and my says it takes 8 minutes for the Sun's light to reach
hope my answer works :)
The answer is d because it said so
Transport of Na+ from a place of low concentration to a place of higher concentration. <u>This is the right answer.</u>
<u />
The sodium-potassium pump is the most common and well-known example of active transport. At the cell membrane, the sodium-potassium pump moves 3 sodium ions out of the cell and two potassium ions into the cell per ATP. Examples of active transport include the uptake of glucose in the human intestine and the uptake of minerals and ions into the root hair cells of plants.
One of the greatest examples of active transport is the movement of calcium ions out of cardiomyocytes. Cells secrete proteins such as enzymes, antibodies, and various other peptide hormones. Amino acids are transported across the intestinal mucosa of the human intestine. The movement of ions or molecules across cell membranes to regions of a higher concentration is assisted by enzymes and requires energy.

Answer:
B: Na(s) + Cl2(g) + 3O2(g) = 2NaClO3(s)
Explanation:
We are looking for enthalpy of formation, so we want to see reactance in their natural standard form.
Thus, we want to see the reactance of Na, Cl2 and O2.
The only option that has the correct form of Na, Cl2 and O2 is B.
Na(s) + Cl2(g) + 3O2(g) = 2NaClO3(s)
Answer:
E = 26.4 ×10⁻²⁷ j
Explanation:
Given data:
Energy of energy =?
Frequency = 4×10⁷ Hz
Solution:
Formula:
E = hf
E = hf
E = 6.6 ×10⁻³⁴ m²Kg/s . 4×10⁷ Hz
Hz = s⁻¹
j = m²Kg/s
²
E = 26.4 ×10⁻²⁷ j.
