Answer:
They have adapted to land, adding features such as embryo retention, a cuticle, stomata, and vascular tissue.
Explanation:
Plants haven't always been on the surface of the earth. Life was restricted to water for a long time. The first plants arose from green algae that resembled the Chara in the image above. Bacteria living in water were the earliest photosynthetic creatures. Soon, as algae evolved, and water drifted away, plants were found on land. Land plants had adaptations that would help their future generations.
The information contained within the gene is copied into a new molecule by the process of transcription. Transcription is a process by which the information from one strand of DNA is copied into a new molecule called messenger RNA or mRNA. Even though mRNA contains the same information it is not the exact copy of the DNA segment. Protein molecules include DNA and RNA and the genetic information is copied into the protein molecules by the process of transcription and translation. Transcription is a process by which the information coded in DNA is transferred to RNA, where as translation is a process where mRNA provides information for the Ribosome the type of amino acid to link with. As amino acids are made up of proteins there will be transfer of information contained in a gene to be transferred to protein. Whereas the function of tRNA is to carry amino acids to ribosome during the transcription hence it does not carry any genetic information where as rRNA combines with the set of proteins to form ribosomes. These rRNA molecule moves along with the mRNA molecule but does not carry any genetic information.
Therefore the answer is d
A phylogenetic tree or an evolutionary tree is a diagram or a "tree" showing the evolutionary relations between various biological species. These diagrams are usually displaying the differences in their physical or genetic characteristics.
Answer:
1) Waterfalls also create erosion. Soft rock erodes, leaving a hard ledge that it washes over. Rocks fall over the waterfall and swirl around in the pool, creating more erosion. The process is repeated, and the waterfall retreats, leaving a gorge behind.
2) Coastal erosion from oceans is always occurring. An eroding beach can lose several feet of sand in one year. In California, waves and rain create mudslides that take down houses by the dozen.
