Answer: To know if a document is a primary source, check to see when the document is published, if it is an autobiography of a person, a diary, a letter, or the documents happen at the time of the event.
The competition between two organisms can be seen if there is only 1 source of food or habitat space and they're competing against each other for the food or habitat.
There is cooperation between two organisms if they are helping each other with resources or alarming each other if there is danger.
Predation between two organisms happen when one organism hunts the other organism for food.
Answer:
mRNA must start membrane protein in the cytoplasm and, after that, continue it in the rough ER.
Explanation:
Protein synthesis is initiated when mRNA meets a free ribosome, the primary structure for protein synthesis. Ribosomes can be found in the r<em>ough endoplasmic reticulum</em> or floating in the cytosol. They read the mRNA code and add the correct amino acid using transference RNA to build the protein.
The <u>rough endoplasmic reticulum</u> is in charge of the synthesis and transport of the membrane proteins. It is also in charge of the latest protein modifications after transduction. Synthesis of membrane proteins <u>starts in the cytoplasm</u> with the production of a molecule portion known as a signal sequence. This portion leads the synthesizing protein and associated ribosome to a specific region in the Rough endoplasmic reticulum where it continues the protein building.
Membrane proteins are synthesized in the endoplasmic reticulum and <em>sent to the Golgi complex in vesicles</em>, where it happens the final association of carbohydrates with proteins. Finally, protein is transported <em>from the Golgi complex to its final destiny, the membrane. </em>
Multi cellular organisms like animals are eukaryotes
An ecosystem is the area in which an animal lives. This can be like a coral reef or a forest.
