Answer:
a. 9:00 pm to midnight.
That is the point in Mars' orbit when it comes closest to Earth, this time at about 38.6 million miles (62.07 million kilometers) from our planet. Mars was visible for much of the night in the southern sky and at its highest point at about midnight.
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.
Underneath lakes and rivers pacfic ocean
Answer:
Lake, -- C) A(n) example of local base level include a stream and or
Terrace, -- E) The flat, broad area surrounding a stream.
Floodplain, -- D) A sweeping bend of a stream which is migrating laterally in a wide, flat valley.
Meander, -- A) A bend in a steep narrow bedrock valley
Base Level -- B) The lowest level to which a stream can erode Remnant of a former floodplain.
Explanation:
- A lake is an example of the be local level is surrounded by the land on all the sides and a terrace is a step-like formation and is gentle spring in nature and a floodplain is a plain that is formed by the and that is adjacent to the base of the rover walls.
- A meander is a sharp turn or bends in the normal course of a rover and the base level is level that the r0ver can erode at the maximum depth and ocean water are considered to be the grand base level.
