amino acid and RNA (or anticodon)

tRNA is used in the process of translation, which is when cells create a protein (polypeptide) from a strand of mRNA just came from the nucleus and is floating in the cytoplasm. This process occurs with the help of ribosomes!

A ribosome binds to an mRNA molecule, and tRNA's come swooping in one at a time to add amino acids to a growing polypeptide chain (protein).

On one end of the tRNA is a set of 3 RNA bases (called an anticodon), that binds perfectly to the opposing next 3 bases on the mRNA strand (called a codon) as it works it way through the ribosome. On the other side of the tRNA is the amino acid that the codon on the mRNA codes for, thus allowing the specific protein to grow 1 amino acid at a time.

The question on this specific query is rather confusing however, in trying to explain human population has grown into a massive populace which can be called overpopulation which in sense causes a specie to be invasive in an ecosystems and more biosystems.

A fossil can be studied to learn __________.

Fudgin [204]

I think the best answer is letter b. which is all of these. By studying fossils, a scientist can determine what organism is found. The scientist also can determine the age of the fossil but it can be recognized as a fossil if it was older than 5,000 years. And lastly, fossils can illustrate the changes of environment, climate and evolutionary patterns of our world.

What is the most likely risk when a society uses wind as an energy source? A. Risk from radioactive material

lesya692 [45]

I think the answer is B because when you think of wind as an energy source you think of wind turbines,, the big things that turn high in the sky. And since it’s in the sky, birds and other flying animals can fly into it and die. Furthermore it can’t be A since wind energy doesn’t use radioactive material, for C I do not believe it uses ground water, and for D the small greenhouse gas emissions it may make to convert the wind energy into electricity (it might not produce any, it depends on how far science has come in the past few years) would be nothing compared to the amount produced burning coal or using gasoline or something like that.

When researchers are measuring plant productivity, they usually harvest and measure above-ground biomass. But with grassland pla

LekaFEV [45]

Answer:

Because of the fibrous root network of grasses.

Explanation:

Measuring below ground biomass of grass plants is technically impossible and difficult because of the fibrous root network different plants form with one another and within the soil. The network virtually makes it impossible to individually extract all the underground biomass of each grass.
