Answer & Explanation:

After a complimentary DNA chain is generated as messenger RNA (mRNA), Sequence of nuclotides in a mRNA directs the addition of a specific sequence of amino acids to form the protein. This usually occur on ribosome.

The polypeptide chain now increases in length by covalent attachment of successive amino acids units, each carried to the ribosome and correctly positioned by its transfer RNA (tRNA). The completion of the polypeptide chain is signalled by a termination codon present in the mRNA.

Anit [1.1K]

Answer:

Class Scyphozoa

Explanation:

In the Scyphozoa class, the predominant and sexual forms are beautiful medusas of varying colors, the true "medusas" often seen on our shores. The polyps are small and correspond to the asexual, short lasting phase. Since this class has the predominant species, the jellyfish, we can conclude that the class that the question is referring to is Scyphozoa.

The medusas are shaped like an umbrella and are different from the group of hydrozoans. They can reach from 2 to 40 cm in diameter. The giant of the group is a North Atlantic jellyfish that reaches 2 meters in diameter.

-BARSIC- [3]

Answer/Explanation:

Essential nutrients such as nitrogen, phosphorus, at specific moderate level are needed for the overall functionality of the aquatic ecosystem. However, when excess of these elements infiltrates the aquatic ecosystem, the nutrient overload causes a surge in the growth of aquatic plant. For example, algal bloom. These increased growth of aquatic plant further takes up space and oxygen, prevents sunlight and later leads to what is known as "dead zone". It is a condition of an ecosystem having little or no biological activity. Aquatic life is impacted negatively when this occurs.

These are the changes that occurs as a result of nutrient loading.

choose two of the four major divisions in the geologic time scale, Describe each one and explain one way in which they were diff
Anastasy [175]

Two of the four major divisions in the geologic time scale are the Archean eon and proterozoic eon.

<u>Explanation:</u>

The Arcean eon is dated from 3900 million years ago to 2500 million years ago. It was in this period the oldest known rocks were deposited.  At that time the atmosphere of earth was composed of  gases like methane, carbon monoxide, ammonia etc.  

The Proterozoic eon is dated from 2500 million years ago to 540 million years ago. It was by the end of Proterozoic era that the Eukaryotas came into existence.  

There are some similarities and differences between Archean eon and Proterozoic eon.  Stromatolites formed by the colonies of cyanobacteria lived in both the eras. This is one similarity between both the eras.  

The weather in the Archean era was hot and wet while the climate and weather of proterozoic era was different from this. Proterozoic era experienced two ice ages.
