Arthropods invaded land about 100 million years before vertebrates did so. This most clearly implies that
horrorfan [7]

The correct answer is - A) arthropods evolved before vertebrates did.

The arthropods have evolved much earlier than the vertebrates. They were on the scene millions of years before the earliest marine forms of the vertebrates. Because the arthropods were on the scene much earlier, they managed to use the newly formed suitable environment on the land. They were initially marine, but with only slight adaptations they were able to adapt to the terrestrial life.

Once the arthropods got out of the marine environment and started to take up the niches in the terrestrial environment, they experienced a real explosion in their evolution and diversification. They were the dominant land dwellers, and because of the lack of competition, as well as the higher levels of oxygen, they managed to reach pretty big sizes for their standards. Unfortunately for them, their brain capacity is limited to a very low level, so once the competition came on the scene, they were quickly pushed from the throne as the dominant terrestrial creatures.

Which of the following best describes the process of transcription during protein synthesis?
jonny [76]

Answer:

The answer is 'D'. Transcription is the process by which a single stranded mRNA is formed from the double stranded DNA.

Explanation:

The central machinery of biology involves three processes- replication, transcription and translation. The process by which DNA doubles itself is called <u>replication</u>. In translation, protein is formed from the messenger RNA or mRNA. The major steps involved in transcription are:

  1. <em>Initiation</em>
  2. <em>Elongation</em>
  3. <em>Termination</em>

In the process of translation, amino acids bind together in the <u>ribosome</u> to form a polypeptide chain.

Each fossil with the layer where it will be present based on are layer A-BIRDS, layer B -dinosaurs , layer C-amphibians, layer D-Corals ,layer E -trilobites.

<h3>What is the oldest fossil layer?</h3>

The Pilbara area of western Australia's Strelley Pool is home to the oldest known fossils. Stromatolites are fossilized mats of microorganisms wedged between sedimentary layers. The fossils have an age of 3.4 billion years.

<h3>How are the layers containing the fossils organized?</h3>

The Law of Superposition, which asserts that in undisturbed rock sequences, the bottom layers are earlier than the top ones, is the foundation for this theory. Because of this, certain fossil discoveries can be dated using the strata—a particular stratum of rock—in which they were discovered.
