11. Which of the following statements is/are correct?
A. Cnidarian can not reproduce sexually
B. Nematocysts are stinging structures that Cnidarians and many other animal Phyla possess.
C. Given the following on the organisms:
I. An animal
II. Multicellular
III. has tissues (diploblastic)
IV. lacks organs
V. is radially symmetrical
This organism could be a member of the Phylum Cnidaria
D. Sea anemones are members of the phylum Echinodermata
E. Members of Cnidaria have three layers of cells (triploblastic) including the endoderm, mesoglea, and ectoderm.

Options A, B, C, D at correct

Explanation:

Cnidarians are a branch of invertebrates characterised by by a radially symmetric body including a saclike internal cavity and nematocysts; stinging structures that aids in feeding. They are also known as coelentrates. They are diploblastic (2 body layer). They also reproduce asexually by various mean including budding. Example include sea anemones, hydra, corals, jellyfish etc

Option B, C, and D.

Explanation:

Phylum cnidaria are group of animals in the animal kingdom that live in aquatic habitat mostly living in marine. They have specialized cells called cnidocytes of nematocysts organelles that help in stinging and capturing prey. Their bodies is consist of mesoglea found between to epithelium layers. They are radially symmetrical .

They have two majory body forms, swimming Medusa and sessile polyps. Cnidarians are diploblastic animals. Cnidaria can reproduce sexually.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.
