Explanation:

Basically ones that are best adapted for their environment. (I'm assuming "he" is Darwin?)

Explanation:

Deoxyribonucleic acid or DNA hold all the instructions that make up an organism. It determines the physical structure and even the function of the different cells that make up all organisms.

The DNA are all stored in the NUCLEUS of cells. Typically, eukaryotic cells have a nucleus except red blood cells. The nucleus has a nuclear envelope that keeps the DNA stored inside but it has nuclear pores that allows it to interact with the cytoplasm.

In order for DNA to be replicated, it needs to be turned into messenger RNA, otherwise known as mRNA. The mRNA decodes the DNA in order for the cell to use the code. The process is called transcription.

Transcription is done within the nucleus. Before the cell can understand what to do with DNA, mRNA transcribes to know what information it needs to produce specidic proteins.

Once transcription is done, it will then bring the information out of the nucleus and into the cytoplasm. The cytoplasm is the viscous gel-like solution that holds the organelles of the cell. In the cytoplasm you have ribsomes.

Ribosomes is where protein synthesis takes place, this is why it is called the protein factory of the cell. It is a molecule that is made up of ribosomal RNA, which direct the chemical processes involved in protein synthesis. For protein synthesis to happen, it will need another type of RNA, which is the tRNA.

tRNA is transfer RNA and they translate the mRNA sequence into proteins. tRNA have amino acids attached to it.

Each 3 bases of the mRNA are collectively known as codons. These codons correspond with specific tRNA that hold the anticodons. These anticodons code for specific amino acids that they also hold.

When they pair up, the tRNA drop off the amino acid which form a chain with the other tRNA amino acids that complete the code. These chain of monomers then make the protein specific to the DNA code that was copied in the beginning.

<u>Translation:</u> process of protein formation is called translation .

In the process of translation, a cell reads information from a molecule called a messenger RNA and uses this information to build a protein. Translation involves “decoding” a messenger RNA and using its information to build a polypeptide, or chain of amino acids .

Translation involve three major steps

• Initiation ("beginning"): in this stage, the ribosome gets together with the mRNA and the first tRNA so translation can begin.

• Elongation ("middle"): in this stage, amino acids are brought to the ribosome by tRNAs and linked together to form a poly peptide chain.

•Termination ("end"): in the last stage of translation, the finished polypeptide is released to go and do its job in the cell.

<u>Organelles involve in translation:</u>

Ribosomes: main process of translation occour at ribosomes.

Rough endoplasmic reticulum: ribosomes are located on rough endoplasmicreticulum .it bound proteins in the vesicles.Vesicles containing proteins are budded off into cytoplasm and move toward golgi apparatus for further modification .

Golgi apparatus: synthesisezed proteins are not functional . In golgi apperatus they are further modefied and processed and stored for a short time and then released toward destination.

Alborosie

Answer:

An ecosystem is biotic, not abiotic.

Explanation:

First, an ecosystem is a biological community of interacting organisms and their physical environment. Second biotic factors are nonliving things whereas biotic factors are living things in an ecosystem you have your producers or plants which then will be consumed by the primary consumers. With the primary consumers feeding the next group of consumers and then the next and then after they die they fertilize the ground allowing the producers to grow as it completes the circle of life.

What would happen if you flew into jupiter?

aleksley [76]

A major problem in sending space probes to Jupiter is that the planet has no solid surface on which to land, as there is a smooth transition between the planet's atmosphere and its fluid interior. Any probes descending into the atmosphere are eventually crushed by the immense pressures within Jupiter
