Worms move using an hydrostatic skeleton. How do worms move?
Nadusha1986 [10]

Answer:

The correct answer is B. Worms move through changes in body structure caused by contraction of muscles compressing their watery fluid.

Explanation:

The hydroskeleton consists of a fluid-filled cavity, surrounded by muscles. The fluid pressure and the action of the muscles that border it, serve to change the body's shape and produce a movement such as digging or swimming. The successive contraction of various metamers, which are provided with bundles of circular and longitudinal muscle fibers, stretching and thickening parts of the body, allow it to move horizontally. Hydrostatic skeletons have a role in the locomotion of annelids, nematodes and other invertebrates. The hydroskeleton has similarities with the hydrostatic muscles.

In an animal cell, which two cell structures do newly-synthesised enzymes have to pass through to reach the external environment
ss7ja [257]

Answer:

Ribosomes, Cell membrane

Explanation:

Ribosomes can be described as structures which are involved in the production of proteins. Ribosomes are hence known to be the protein manufacturing units of a cell. As enzymes are also proteins,they will be synthesized in the ribosomes.

Cell membrane can be described as the membrane which is present outside the cell or which separates the cell from the external environment.

For an enzyme to pass through the external environment, it will have to pass through the ribosomes and the cell membrane.
