Answer:

The correct answer is option A, that is, snowline.

Explanation:

The climatic boundary between a snow-covered and snow-free surface is known as a snowline. The real snowline may amend seasonally, and be either substantially lower or higher in elevation. The permanent snowline refers to the level, that is, above which all the year snow will lie.

It is an umbrella term for various elucidations of the boundary between the snow-free surface and snow-covered surface.

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.

Describe the pathway of a protein being made in a cell...from nucleus to vesicle

Karolina [17]

Answer:

ER → ER-to-Golgi transport vesicles → Golgi cisternae → secretory or transport vesicles →cell surface (exocytosis) (see Figure 17-13). Small transport vesicles bud off from the ER and fuse to form the cis-Golgi reticulum.

A group of hikers find a fallen tree in a forest. The dead tree trunk is covered by mushrooms and other fungus. Later, they find

Agata [3.3K]

Answer: D. The fungus and bacteria organisms are obtaining the energy they need by decomposing organic matter like dead trees and old apples.

Fungi is the primary decomposer of biological waste in forest ecosystem. Fungi grows on the branching network of hyphae which provide it more penetration potential towards the litter. Wood decaying fungi has enzymes required for decomposition of lignin, a chemical substance found in wood. Fungi decompose organic matter by releasing enzymes which breaks down the decaying matter, after that they absorb the nutrients in the decaying material. The left residue in the organic matter includes sugars and amino acids are degraded and decomposed by the bacteria.
