Answer:
Options B.
They are both diploblastic.
Explanation:
Cnidarians are group of aquatic animals that live both in fresh water and Marine water. They are distinguished by the possession of specialized cells called cnidocytes for capturing prey. They are radially symmetrical and have two body layers ectoderm and endoderm separated by jelly layer called mesoglea.
Examples are Hydra, corals, sea anemone and jelly fish.
Ctenophores are phylum of Marine animals that are found in every where. They are characterized by vast of cilia which is use for swimming. They are bilaterally symmetrical , they have mouth and don't have anus. They don't have respiratory, excretory and circulatory system. They are diploblastic i.e they have two body layers but some are triploblastic.
They have nemacyctes for capturing prey.
Examples are nuda, tentaculata e.t.c.
Answer:
mass doubled makes KE twice as large
velocity doubled makes KE 4 times as large
Explanation:
Try it with an example
m = 4
v = 8
KE = 1/2 m * v^2
KE = 1/2*4 * 8^2
KE = 1/2 * 4 * 64
KE = 128
Now double the mass
m = 8
v = 8
KE = 1/2 8 * 8^2
KE = 1/2 8 * 64
KE = 4 * 64
KE = 256 double what it started out as.
Now do it again.
m = 4 That was the original mass
v = 16
KE = 1/2 4 * 16^2
KE = 2 * 256
KE = 512
When the velocity is doubled the KE becomes 4 times as big.
4*128 = 512
Cells make up the basic structure of an organism, and they perform basic life functions for the organism.
