C.It is a frameshift mutation that changes many amino acids.

Explanation:

Due to the triplet nature of gene expression by codons, the insertion of the single Adenine nucleotide will disrupt the reading frame of the gene (frameshift mutation), such that it is no longer evenly divisible by three.

Thus, resulting in a completely different translated protein from the original.

In which system of plant do the tissues xylem and phloem work?

Answers

In vascular system of plant do the tissues xylem and phloem work

Xylem cells are non-living cells that are part of a plant's vascular or conducting tissue. Xylem transports water from the roots upward through the plant, along with nutrients. Xylem is found in vascular bundles, that can be arranged in a circular fashion or a scattered fashion in woody and non-woody parts of plants with wood. The veins found in leaves, stems and roots which are interconnected contain xylem. Phloem, also part of the vascular tissue, conducts nutrients to parts of the plant where needed, particularly sugar produced by photosynthesis. Phloem cells are living and transport sap from the leaves, to roots or to storage areas in a plant such as a bulb. Phloem sap moves from sugar sources to sugar sinks due to turgor pressure gradient.

If you go back far enough, there is a chance that you inherited no DNA from a particular ancestor.

What is the main relationship among archosauria, diapsida, and reptilia clases?

Answers

Answer:

Archosauria (the "ruling reptiles") is a major group of diapsids, differentiated from the other diapsids by the presence of single openings in each side of the skull, in front of the eyes (antorbital fenestrae), among other characteristics. This continues the tetrapod trend of the reduction of skull bones by the fusion of multiple bones and the opening of fenestrae in the skull. This helps to lighten the skull, provides more room for muscles and other tissues, and allows more skull flexibility (kinesis) when eating. Other typical archosaurian characteristics include another opening in the lower jaw (the mandibular fenestra), a high narrow skull with a pointed snout, teeth set in sockets (called thecodont tooth implantation), and a modified ankle joint.

Diapsids ("two arches") are a group of amniote tetrapods that developed two holes (temporal fenestra) in each side of their skulls about 300 million years ago during the late Carboniferous period.[1] The diapsids are extremely diverse, and include all crocodilians, lizards, snakes, tuatara, turtles, and birds.[2] Although some diapsids have lost either one hole (lizards), or both holes (snakes and turtles), or have a heavily restructured skull (modern birds), they are still classified as diapsids based on their ancestry. At least 7,925 species of diapsid reptiles[3] exist in environments around the world today (nearly 18,000 when birds are included).

Reptilia, presented as a Class in our classification, includes turtles (Testudines), snakes and lizards (Lepidosauria), crocodiles and their relatives (Crocodilia), and birds (Aves), as well as a number of extinct groups.
