What do the tympanic membranes do for the frog?

Biology
1 answer:
BabaBlast [244]3 years ago
7 0
A tympanic membrane, (is also called a tympanum), is the circular patch of skin directly behind the frog’s eye that we commonly call an eardrum. It functions much like our’s does.

The tympanum sends sound waves to the middle of the war then to inner ear, which allows a frog to hear both in the air and below water.

How many new volumes would each new cell contain whenever a cell splits?
Elenna [48]
The specific volume will be different for various kinds of cells. The safe answer would be that the new cell will pretty much have the same volume as the one that it divided from. This is true for most eukaryotic cells unless other factors like epigenetics or mutations come into place.

One example of moments a cell would increase in volume is during hypertrophy. This simply means that the cell is increasing in size (compared to: hyperplasia -- which is an increase in number of the cells). Hypertrophy is definitely an increase in volume of the cell but this doesn't necessarily translate to cell division (i.e. just because the cell is big now, doesn't mean it will still be big when it divides).

Another moment of increasing volume of the cell and now also related to cell division would be during the two stages in the cell cycle (i.e., G1 and G2 phases). This is the growth phase of the cell preparing to divide. However when mitosis or division happens, the cells will normally end with the same volume as when it started.

This are safe generalizations referring to the human cells. It would help if a more specific kind of cell was given.

Consider the following food chain: garden plants are eaten by snails, which are eaten by birds, which are eaten by the household
SIZIF [17.4K]
The garden plants and snails stay balanced as they are still being eaten. However, if the cat is removed, the birds will overpopulate and then the snail would be eaten and decrease faster which gives garden plants an increase in population due to the decrease in snails. Hope this helps!

Evgesh-ka [11]

Answer:

<em>The statement that is incorrect is :</em>

<em>Robert wanted to see if his theory was true that cigarette smoke will influence web-building in spiders.</em>

Explanation:

A theory can be described as a descriptive explanation of a phenomenon which is supported by valid experiments and careful examination of facts. As Robert, has not conducted any experiments nor has proved his study with reference to facts, hence it cannot be considered as a theory.

Robert wanted to see if his observation was true that cigarette smoke will influence web-building in spiders will be the correct statement that could be used.
