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.

Look in explanation
Explanation:
The sun provides energy to plants. The plants are eaten by herbivore/omnivores transferring the energy from the plant to the herbivore/omnivore, then the carnivore eats the herbivore/omnivore which gives the carnivore the energy
Answer:
Explanation:
Cellular respiration -
Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
Biology is a branch of science that deals with living organisms and their vital processes. Biology encompasses diverse fields, including botany, conservation, ecology, evolution, genetics, marine biology, medicine, microbiology, molecular biology, physiology, and zoology.
Answer:
A living being or organism is a complex set of organizational material, in which molecular communication systems intervene that relate it internally and with the environment in an exchange of matter and energy in an orderly manner, having the ability to perform the basic functions of life that are nutrition, relationship and reproduction, in such a way that living beings work by themselves without losing their structural level until their death.
Explanation:
The matter that composes living beings is formed in 95% by four elements (bioelements) that are carbon, hydrogen, oxygen and nitrogen, from which biomolecules are formed: 3 4
Organic biomolecules or immediate principles: carbohydrates, lipids, proteins and nucleic acids.
Inorganic biomolecules: water, mineral salts and gases.
These molecules are constantly repeated in all living beings, so the origin of life comes from a common ancestor, as it would be very unlikely that two living beings with the same organic molecules have independently appeared.5 6 Stromatolites have been found 3700 million years old, 7 so that life could have arisen on Earth 4100-3800 million years ago.1 8 9
All living things are made up of cells. Inside these are carried out the sequences of chemical reactions, catalyzed by enzymes, necessary for life.
The science that studies living things is biology.
