Explanation:
Friction is the name of the force that opposes motion.
Answer:
B. They deliver oxygen to the blood.
Explanation:
The lungs, nose, and trachea are organs of the <u>respiratory</u> system. All three help circulate <u>oxygen</u> through the body's system. <em>*I might be wrong though* </em>
Answer:
The dust and gas particles of a slowly rotating nebula gradually came together to form a cloud with a huge central bulge surrounded by a flat ring of dust and gas. The sun was formed from the material in the bulge. The flat ring became several rings. In each ring, a planet formed and continued to revolve around the sun in the plane of the ring it came from.
Explanation:
Answer:
A pathway by which counter ions can flow between the half-cells without the solutions in the half-cell totally mixing.
Explanation:
Electrochemical cell -
Device used for the conversion of chemical energy to electrical energy is called electrochemical cell.
it is based on oxidation reduction reaction.
Electrolyte is a solvent in which ions are dissolved and two electrodes are dipped in it.
Anode electrode is responsible for oxidation, and the cathode electrode is responsible for reduction.
The electrochemical cell is composed of two electrodes dipped in an electrolyte , and which are further connect by salt bridge .
Salt bridge firstly connects the circuit and allows the movement of ions and , resists any mixing of the solution , and helps to maintain the electrical neutrality condition .
Hence , from the question , the correct option about salt bridge is the first option .
Explanation:
Strength of intermolecular forces depends on the number of carbon atoms present in a compound. More is the number of carbon atoms attached linearly to each other more will be the surface area occupied by it. Hence, more is the strength of the compound.
This means that more is the branching present in a compound or lesser is the number of carbon atoms present in it then less will be the strength of intermolecular forces in the compound.
Thus, we can conclude that given compounds are placed in order of decreasing strength of intermolecular forces as follows.
