Answer:
Chimpanzees are the animals which are the closes to humans. Infact, the genome of chimpanzee is 98.6% similar to the genome of humans. Humans are thought to have evolved from chimpanzees.
Chimpanzees walk on all fours and have longer arms than legs. They are called “knuckle walkers” because they use their knuckles for support. Like humans, chimps have opposable thumbs and opposable big toes which allow them to grip things with their feet. This feature of chimpanzees for using knuckles for support makes them unique.
Chimpanzees are the only kind of animals which have the capability to groom each other which makes them unique.
Answer:
The correct answers to the question are:
- The concentration of solute bathing the inner side of the plant cell membrane should be high.
- The concentration of solute bathing the outer side of the plant cell membrane should be low.
Explanation:
- Turgidity can be defined as a condition in which the cell membrane of the plants cells becomes completely extended as a result of which it pushes tightly against the cell wall.
- This happens when the cell takes up water from its environment and stores it in the vacuoles.
- Water enters to the inside of the cell by the process of Osmosis.
- Osmosis can be defined as the process by which molecules tend to move or diffuse from a region where its concentration is high to another region where its concentration is low, provided the two regions are separated by a semi-permeable membrane.
- In any region, the concentration of solute and and concentration of solvent bears an inverse relationship. This means that the region where the solute concentration is high, the solvent concentration is low and where the solute concentration is low, the solvent concentration is high.
- In the given question, as the cell takes up water from the surrounding into its vacuole to become turgid, so by the concept of osmosis, the concentration of water must have been high outside the cell and low inside the cell.
- Again by the inverse concentration concept of solute and solvent, the concentration of solute inside the cell should be more than the concentration of solute outside the cell.
After leaving the source of emf, an electron's potential energy is lower.
<h3>Describe electromotive force.</h3>
The voltage or potential difference of a battery or other electrical energy source is known as the electromotive force. A resistor is where the emf is coming from. The potential energy of an electron will now be higher than the potential energy of an electron before it leaves the source emf.
Now, the potential energy of an electron before leaving the source of electric current will be greater than the potential energy of an electron after leaving the source of electric current because the resistor connected to the source of electric current will reduce the potential energy by converting some of the energy to heat.
