Answer:
D. all of the above
Explanation:
The water molecules have surrounded salt (NaCl) ions in the given diagram.
Salt get dissolve in water as both are polar, having positive and negative charges and both have electrical charges. Covalent bonds in water molecules are more stronger than the ionic bonds of salts, that is why salt dissolve in water.
Water molecules and salt molecules form electrostatic interaction in which the positively charges ends of water molecules are attracted to the negative chloride ions (Cl- ion) while negative ends of the water molecules are attracted to the positive sodium ion (Na+ ion).
Water molecule breaks the ionic bond between sodium and chloride ions. Water molecules form hydration shell around sodium (Na+) and calcium (Cl-) ions and allow the salt to dissolve in water and forma homogeneous solution.
Hence, the correct option is "D. All of the above".
Answer:
Okay so start with diagramming the phases of Mitosis (interphase, prophase, metaphase, anaphase, telophase, cytokinesis) then draw what all the phases would look like for a plant cell. You can search what a plant cell looks like in mitosis and use it as a reference.
Explanation:
the color coding is for drawing each thing in the phases of mitosis
Answer:
the electrical impulses get sent through the conduction pathways which cause ventricles to contract and this allows heart to pump blood.
Explanation:
The electrical impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles.
And it should be understood that, an electrical stimulus is generated by the sinus node (also called the sinoatrial node, or SA node). The electrical stimulus travels down through the conduction pathways and causes the heart's ventricles to contract and pump out blood.
Answer:
D, Mastodon tissues contained protein sequences similar to those of modern-day elephants.
Explanation:
