The evidence supporting the idea that modern birds and reptiles share a common ancestor is that feathers are a derived characteristic that first evolved in reptiles. Feathers represent an evolutionary derived trait.
In evolutionary biology, an autapomorphy is a distinctive phenotypic trait referred to as a derived trait, which is unique to a particular group/taxon.
The derived traits are phenotypic features that arise during the evolution of a particular taxonomic group.
These traits (derived traits) differ from the phenotypic trait of the ancestor of the group.

<h2>Vasa recta </h2>
Explanation:
The vasa recta is a specialized capillary that branches from the efferent arteriole; The blood flow in the vasa recta runs parallel, but in the opposite direction to the flow of tubular filtrate within the nephron loop
- The vasa recta capillaries are long, hairpin-shaped blood vessels that run parallel to the loops of Henle
- The hairpin turns slow the rate of blood flow, which helps maintain the osmotic gradient required for water reabsorption
- Absorbed water is returned to the circulatory system via the vasa recta, which surrounds the tips of the loops of Henle
- Because the blood flow through these capillaries is very slow, any solutes that are reabsorbed into the bloodstream have time to diffuse back into the interstitial fluid, which maintains the solute concentration gradient in the medulla; this passive process is known as counter-current exchange
Answer: Information stored in DNA must be translated into functional products.
Explanation: DNA is a short form of deoxyribonucleic acid. DNA is a type of nucleic acid. There are two types of nucleic acids: DNA and RNA (ribonucleic acid).
DNA is a double-stranded helical molecule that contains the complete information for the synthesis of a functional gene product. The functional gene product is usually a protein.
DNA is first copied into a messenger RNA (mRNA) in a process known as transcription. This process is catalyzed by the enzyme RNA polymerase. This process occurs in the nucleus.
The mRNA leaves the nucleus to the ribosome where it is used to produce a protein. This process is called translation and occurs in the ribosome. The protein is the functional product that expresses its function in the organism.
