Explain why increased ecosystem diversity contribute to increased biodiversity in the biosphere
Leto [7]

Answer: Diversity, referring to the state of having many different organisms cohabitate within an area is a desirable outcome for many ecosystems. The presence of a wide spectrum of different organisms allows for more life to be able to thrive in an ecosystem. For example, an ecosystem with a wide array of shrubs, grasslands and forested areas is able to accommodate more life forms than an ecosystem of just forest. This increased capacity to support life directly improves the capacity of the biosphere to support life as well, diversity leading to growth.

In order for translation to occur: Please choose the correct answer from the following choices, and then select the submit answe
sweet-ann [11.9K]

Answer:

there must be large numbers of free amino acids present in the cytoplasm

Explanation:

<em>In order for translation to occur, </em><em>there must be a large number of free amino acids in the cytoplasm.</em>

<u>These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.</u>

During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.

Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.

What state of mind does alcohol initially produce in most adults after the first drink?
Cerrena [4.2K]

Answer:

euphoria

Explanation:

When a person takes alcohol, he/she feels relaxed and euphoric. This happens because of the release of endorphins. Endorphins are a chemical that produces the feeling of pleasure and happiness. After the first drink, the content of alcohol in blood is 0.05-0.06% which is sufficient to develop euphoric feeling.  

However, some of the consumers have also claimed that it act as a depressant.
