Answer: The earthworm contracts and extends in its movement, but the nematode moves side by side.

Explanation:

NOTE: By mode of location, we mean the way it moves.

The skin of a nematode is very unusual in that it secretes a thick outer cuticle which is both hard and flexible. And this cuticle makes it sustain a side by side mode of location. The closest thing a roundworm has to a skeleton is its cuticle and it uses it as a support and balance point for movement. Long muscles lie just underneath the epidermis and are all aligned longitudinally along the inside of the body, so the nematode can only bend its body from side to side, not contract or extend itself.

Whereas the earthworm extends and contracts as its mode of location.

An earthworm moves by using its two different sets of muscles: circular muscles for looping around each segment, and the longitudinal muscles for running along the length of the body.

The contraction of the circular muscles make the earthworm stretch becoming longer and thinner. The earthworm uses its longitudinal muscles to contract and thus becomes shorter and wider or it bends from one side to the other, pulling the body forward in the process. The earthworm withdraws the front setae and uses its rear setae to anchor itself at the back. Then the earthworm uses its circular muscles to lengthen and push itself forward again.

What is the lowest output value approached by the function f(x)=2x−5?

Bond [772]

Are you sure you wrote it right? :-(

The function f(x)=2x-5 is a linear function.

Unless otherwise stated (and that does not seem to be the case) in the real numbers domain, x may assume any value.

The same can be said to y.

So, the lowest output value approached by this function is -∞

(minus infinity).

Answer:

The eruption of the volcanoes, and the occurrence of the earthquakes on the planet and the spilling of the lavas, and the smoke-filled air hat comes to from the vent of the large craters.

As most people think that the volcanoes are present on the land areas only does not mean that they are confined to the above surface of earth they are also characterized by the deep hydrothermal vent and the most pope thus are surprised to know about them as they don't know that they are the primary place for the origin of the first life forms n the earth in the single-celled bacteria.

They generally spill out the lavas and the magmas and this is called sth submarine volcanoes and ends to occur along the mid-ocean ridges. And are known to give out an estimated 75% of the volume of the lavas on earth.

They are also known as the seamounts that are created from the extinct volcanoes that occur in 1000 to 4000 meters depth of the seafloor.
