Actually it is the females the mostly build the nests the males will help build it sometimes both males and females will build it but typically it is females and that goes for all birds.
"Females typically build nests, but sometimes both parents or just the male"
<span>I believe it is light, but this is kind of a confusing question. Technically there is a independent and dependent variable in the question. The variable being manipulated is light, and the earthwork activity depends on the light. </span>
Answer:
Golgi receives a vesicle containing newly synthesized proteins that were sent by the endoplasmatic reticulum. Then it modifies the proteins and sends them where they need to go.
Explanation:
Protein synthesis is initiated in the cytoplasm when mRNA meets a free ribosome, which is the primary structure for protein synthesis. They read the mRNA code and add the correct amino acid using transference RNA to build the protein. The synthesizing protein is driven to the rough endoplasmic reticulum and translocated to the lumen. Once there, the protein suffers a few modifications, one of them is folding to become functional. Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are <u>packaged into vesicles</u> and <u>sent to the Golgi complex</u>, where it occurs the <em>final association of carbohydrates with proteins</em>. The Golgi complex <u>sends proteins to their different destinies</u>. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organ. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.
Answer:
a. A hypothesis that does not generate a testable prediction is not useful.
Explanation:
In the scientific method, we generate a hypothesis to explain a phenomenon. After this, it is necessary to create a method to test the hypothesis and make predictions. Moving forward, we test this methodology, generating results and reject or not reject the hypothesis. If the hypothesis can't be tested, the scientific method can't be applied.
An example of vesiscle-mediated transport would be cell secretion by exocytosis.
The reason why this would be an example of vesicle-mediated transport is because all the other types of transport listed here are not something you would call vesicle-transport; the substances don't really get transported in vesicles. This is different in exocytosis where the compounds gets packaged into vesicles.
