When the elodea is underwater where is the carbon dioxide coming from

1 answer:

5 0

The elodea is getting the carbon dioxide from its environment like when underwater animals breathe out carbon dioxide the plants will use that carbon dioxide. The plants can also get the carbon dioxide from the atmosphere which can "dissolve" in water.

Why do non-native plants threaten native plants?

Liono4ka [1.6K]

Destruction and replacement of ournative plants by invasive species has several significant consequences. Wildlife that depends on native plants is often unable to adapt and may be forced to leave the area or die out.Invasive aquatic plants can completely fill a water body, driving fish and wildlife from the area.

Where must an mRNA attach before protein production can begin?

kap26 [50]

Answer:

to a Ribosome

Explanation:

mRNA is produced inside the nucleus of a cell according to the genetic information present in the DNA of the cell. this process is known as Transcription.

Then it's sent to ribosomal subunits in the cytosol through nucleopores. then it attaches to the ribosome. the ribosome reads the nitrogenous base sequence and pairs the tRNAs with complementary nitrogenous bases. <u>(your answer is here, but if you want to know more, continue reading it.)</u>

Each tRNA contains a tri-nucleotide that is collectively known as an anticodon which has the complementary bases of the relevant codon on the mRNA.

Each tRNA has captured a protein. the type of protein is determined by the sequence of the anticodon.

It means two tRNAs with two different anticodons cannot bring the same protein to the ribosome.

the Ribosome separates the proteins attached to tRNAs and links them as a chain.

the final result is a polypeptide chain. I explained to you the basic protein synthetic process.

sukhopar [10]

Answer:

The options are

A) electrical energy.

B) mechanical motion.

C) heat and light energy.

D) electrical and heat energy.

The answer is C) heat and light energy.

Explanation:

Chemical energy in the wood is lit up by fire and a burning process begins to occur. Burning involves a substance being consumed by fire and fire aids in the conversion of some forms of energy to mainly light energy as a result of the burning flames and also to heat energy as a result of the high temperature in the form of heat which the fire brings into play.

This validates the stored chemical energy in the logs being changed into light and heat energy.
