Plants have a cell wall and chloroplasts; animal cells do not have either
Hope this helps : )
Answer:
The correct answer is There are very few receptors on the soles of a person's feet.
Explanation:
The skin is made up of a layer called the epidermis. The epidermis contains cells that are very sensitive and are responsible for perceiving everything we touch by sending this information to the brain.
All the nerve endings that our body has are in charge of controlling the sense of touch.
All the sensations that we perceive when touching something with any part of the body are linked to the sense of touch.
The most sensitive places on our body are palms, lips, tongue, soles of the feet, fingertips, eyelids and face.
Therefore the correct answer is There are very few receptors on the soles of a person's feet.
The correct answer is (A)
Burning of wood is a chemical change as new substance is formed during the burning of wood which is not reversible.
Now, what happened during the burning of wood?
In the case of burning wood, stored potential energy( in the form of chemical energy) in the log is released due to heating by other excited atoms. This chemical reaction is called combustion that requires oxygen. We can also say that combustion is change of potential chemical energy into kinetic energy in the form of heat.
When in a certain situation, organisms with traits more suited to survive in that situation often survive more often and are able to reproduce more, which means that their genes eventually dominate the gene pool.
For example: take a light moth population and a dark moth population. They live in a forest with dark trees, so the dark moths blend in more and are harder to find and hunt. As a result, more of them survive than the light moths, so more of them are reproducing and passing their genes along.
Over time, those genes may become the only traits of that variety that the organism can have, so they grow to evolve and adapt to their surroundings.
<span>Adaptations are the result of evolution in different living organisms. This process occurs amazingly through gene mutation but it takes a very long period in time. Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. An example of this are the bills of a bird and the fur of bears that they generally need for their survival; birds for hunting, and bears to protect them from low climate areas.</span>
