Which best describes heat by conduction?

Biology
1 answer:
Anna35 [415]3 years ago
5 0
The answer to this is A.

Heat transfer by conduction only happens when the two objects are in contact in each other. This is because conduction relies on the collision of molecules of the two object.

When an object has a higher temperature, their molecules will have a higher kinetic energy. They move faster and eventually collide into other slower molecules, then spreading their energy out and making those molecules move faster and have a higher kinetic energy too. Both object will now have the same temperature (ie. Thermal equilibrium is achieved).

Therefore, as the air molecules touches the ground, they collide to the ground molecules and therefore warming it up. The answer is A.

Receptor cells for our sense of ________ reproduce themselves every week or two. vision hearing taste equilibrium
patriot [66]
Taste

Taste buds or taste receptor cells in the tongue allow a person to taste the different flavors of the food he or she eats. An average person has around 10,000 of these cells, which gets replaced every week or two. As a person gets older, cell replacement is much slower and some of these cells do not get replaced anymore. An older person may then have only about 5,000 working taste buds.

A heritable trait is one that A heritable trait is one that is determined at least in part by genes passed from parents to offsp
sveta [45]

Answer:

A heritable trait is one that is determined at least in part by genes passed from parents to offspring.

Explanation:

A heritable trait is the one which is passed from parents to offspring. While environmental factors can still have an effect on such traits, they are at least in part determined by the genes passed on from the parents. They are not always inherited specially if they are recessive.

Heritable traits are passed on through the genetic information stored in germ cells. If a trait is acquired during lifetime of an organism and was not present when the organism was born, such a trait wont be passed on to the next generation and wont come under heritable trait. For example if mice tails are cut for ten generations, the mice born in eleventh generation would still be born with tails.
