Answer:
The students with the purple shirts are moving through the gym doors most often.
Explanation:
- The students with the purple shirts represent potassium ions
- Potassium ions move freely across the membrane by passive transport and are important in maintaining membrane potentials
- The movement of sodium ions is through active transport therefore this is a process that requires energy (ATP) and thus these ions are less likely to move across the membrane often
Correct answer: D). Tides
The tidal force is generated by the combination of gravitational attraction between the earth, moon and the sun and the rotation of Earth-sun and the earth-moon system. The tides rise and fall on the ocean surfaces. The moon has a large effect on the generation of the tides than the Sun.
Thus, the correct answer would be option D.
The parts of one nucleotide a nitrogenous bases (labels C and D), a pentose sugar (labels B and E) and phosphate group (labels A and F).
<h3>What is a nucleotide?</h3>
A nucleotide is a building block of nucleic acids (either DNA or RNA) that form the genetic material of an individual.
Phosphate groups form the backbone of the double helix and bind to pentose sugars in adjacent nucleotides.
Nitrogenous bases bind opposite DNA strands by hydrogen bonds, they include Adenine (A), Guanine (G), Cytosine (C) and Thymine (T).
In this case, the labels include:
- Label A: phosphate
- Label B: deoxyribose sugar
- Label C: nitrogenous base
- Label D: nitrogenous base
- Label E: ribose sugar
- Label F: phosphate
In conclusion, the parts of one nucleotide a nitrogenous bases (labels C and D), a pentose sugar (labels B and E) and phosphate group (labels A and F).
