An earthworm receives support and shape from its fluid-filled cavity. It has Hydroskelton
Explanation:
The muscle of earthworm encloses with two layers of muscle which is circular and longitudinal. There is fluid cavity between digestive part and muscle. it is called coelom and fluid is coelomic fluid. This fluid work as hydrostatic skeleton.
It provides resistance to muscular contraction. It helps the earth worm to applying the force and change the shape. Mostly hydrostatic Skeleton organism has more or less cylindrical. This type of Skeleton found in soft bodied invertebrates.
I think the answer is bed load
Explanation:
bed load describes particles in a flowing liquid that is transported along the stream bed
Answer:
a. are probably built by different genes.
Explanation:
Although sharks and dolphins are aquatic animals belonging to the vertebrate group, sharks are fish while dolphins are mammals. Sharks belong to the class Chondrichthyes which are fish that have a cartilaginous skeleton. On the other hand, dolphins are mammals (class Mammalia) which are animals mainly characterized by the presence of mammary glands. In consequence, both species are not closely phylogenetically linked, thereby those genes involved in the development of the integumentary system (skin) in both species are expected to be different.
Western Honey Bee: They Pollinate The Earth by spreading Pollen around that has latched onto their feet while they took a walk on the flower head. Bull Frog: Eats flies, lays eggs, lowers the amount of insects near the area, increases the population of bullfrogs. Homo Sapiens Epoch 74 ( humans ) : Pollute the earth, kill animals, make a mess, overpopulate the world, leaves barely any room for animals. Hamsters: Digs holes in the ground, eats seeds, poops everywhere, sometimes eats bugs.
