Correct Answer: A) They are diplobastic animals.

Explanation

Phylum Cnidaria is a group of animals that includes jellyfish, corals, and sea anemones. The question is asking which of the following statements is correct about this group. The options are: A) They are diploblastic animals, B) Body is sac-shaped with three openings, C) They are bilaterally symmetrical, and D) They are triploblastic animals with two openings.The correct option is A, which states that they are diploblastic animals. Diploblastic means that the animals have two germ layers, the ectoderm and endoderm, which are separated by a gelatinous layer called mesoglea.Option B is incorrect because the body of Cnidarians is not sac-shaped with three openings; instead, it is characterized by radial symmetry, with a central mouth and tentacles surrounding it.Option C is also incorrect because Cnidarians are not bilaterally symmetrical. Bilateral symmetry means that an animal can be divided into two equal halves along a plane that runs from head to tail. However, Cnidarians cannot be divided into two equal halves in this way.Option D is also incorrect because Cnidarians are not triploblastic animals with two openings. Triploblastic means that an animal has three germ layers, the ectoderm, mesoderm, and endoderm, while having two openings refers to animals that have a mouth and an anus. However, Cnidarians have a single opening, which serves as both the mouth and anus.In summary, option A is the correct statement about phylum Cnidaria, which is that they are diploblastic animals.

Correct Answer: A. the xylem is more interiorly located than the phloem

Correct Answer: C. 5' - GATCACG - 3'

Explanation

This question is essentially asking, Which of the following is a point mutation of the original sequence? A point mutation is a mutation in which one base pair of DNA is substituted for another. A point mutation will not change the reading frame of a DNA sequence because it does not involve adding or removing any bases. The only answer choice that is identical to the original sequence with the exception of one base pair being changed for another is 5'GATCACG3', so this is the correct answer.

Correct Answer: B. C12H22O11

Explanation

The disaccharide maltose is formed by the dehydration synthesis reaction of two glucose monomers. When simply adding the two glucose monomers together, it may be thought that the summation of the two (C12H24O12) will be the chemical formula of maltose. However, this does not account for the dehydration synthesis reaction in which one oxygen atom and two hydrogen atoms disappear. After accounting for these molecules the chemical formula for maltose will be represented by C12H22O11.

Correct Answer: A. N40

Correct Answer: A. Ova and spermatozoa

Correct Answer: D. plants react slowly to external stimuli while animals react more quickly

Correct Answer: D. xylem . . . phloem

Explanation

The correct answer is xylem . . . phloem. Water and nutrients move from the roots through plant stem to the rest of the plant. Stems are made from three tissues: ground, dermal, and vascular. Vascular tissue is primarily divided into xylem, which primarily transports water, and phloem, which primarily transports sugars.
