answer
Fossil evidence clearly shows that life is old and has changed over time. The study of anatomical features of animals of different species. The process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth
Answer:
Explanation:
In general, frogs have protruding eyes, no tail, and strong, webbed hind feet that are adapted for leaping and swimming. They also possess smooth, moist skins. Many are predominantly aquatic, but some live on land, in burrows, or in trees.

The correct answer is: introns
Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:
• Addition of a 5' cap to the beginning of the RNA
• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA
• Splicing- removal of introns and linking the exons
After these steps mRNA is mature and used for the further steps (e.g. translation).
Sometimes some genes are alternatively spliced.
The answer should be C, Sudan red solution.
Sudan red solution dissolves in lipids, which can show a color of orange/red if lipid is present.
On the other hand, Biuret solution/reagent is used to test for proteins, and it'll show a color or purple if protein is present.
Iodine solution is used to test for the presence of starch, and it'll show a blue black color if starch is present.
And lastly, Benedict's solution is used to test for reducing sugars, and it'll show a brick red color (or green as small amounts) if reducing sugars are present after heating under boiling water bath.
