How are marine worms and sponges different?
a.) Sponges live in mud, sand, or underneath rocks.
b.) Marine worms exist in more than one phylum.
c.) Marine worms are invertebrates.
Answer:
Segmented marine worms are easily identified by the many visible rings that make up their bodies. Many marine species are found on the sea bottom but are not restricted to it. Sponges are filter-feeding, colonial animals which live together as a larger unit. They appear to be plants but are in fact invertebrate animals. So the answer is (A.) I think.
Filter-feeding colonial organisms, sponges live as a single bigger group. Although they seem like plants, they are actually invertebrate animals. Thus, option A is correct.
What are the different features in worms and sponges?Bilateral symmetry describes how all worms have the same body on both sides. They lack scales and real limbs, even though they might have appendages like fins and bristles.
Each of them belongs to a different phylum, and each phylum is very diversified. They all have the trait of being primitive, basic biological creatures.
Segmented saltwater worms are easy to identify because of their body's many distinguishable rings. The sea floor is home to many marine creatures, but this is not the only place they may be found.
Therefore, Sponges live in mud, sand, or underneath rocks.

Data that indicate that the genetic code changes frequently.
Data that are inconclusive about the nature of.
the genetic code.
Data that indicate that some organisms use one or more alternate codes.
Data that indicate that the genetic code is the same in all organisms tested so far.
Answer:
hi here is your answer....
Explanation:
Data that indicate that the genetic code is the same in all organisms tested so far.
becuase,
The genetic code is nearly universal, and the arrangement of the codons in the standard codon table is highly non-random. The three main concepts on the origin and evolution of the code are the stereochemical theory, according to which codon assignments are dictated by physico-chemical affinity between amino acids and the cognate codons (anticodons); the coevolution theory, which posits that the code structure coevolved with amino acid biosynthesis pathways; and the error minimization theory under which selection to minimize the adverse effect of point mutations and translation errors was the principal factor of the code’s evolution.

How does the heliocentric model of planetary motion explain a star's path across the night sky?
The sky is fixed and rotates around Earth.
Earth moves along its orbit daily to follow the stars.
The rotation of Earth makes objects in the sky appear to move.
Each star creates a different amount of light, imitating movement.
Answer:
The Rotation of earth makes objects in the sky appear to move
The heliocentric model of planetary motion explains a star's path across the night sky by The rotation of the earth makes objects in the sky appear to move; this is in Option C, as this is one of the best concepts on the planetarium models.
What is the significance of the planetary model?The planetary model is very significant, as the heliocentric model, proposed by Nicolaus Copernicus, explains that the sun is at the center of the solar system and shows that the planets, including Earth, revolve around the sun. This heliocentric model provided a more accurate explanation of the movements of the planets and paved the way for future research.
Hence, the heliocentric model of planetary motion explains a star's path across the night sky by The rotation of the earth makes objects in the sky appear to move; this is in Option C, as this is one of the best concepts on the planetarium models.
