Answer:
Explanation:
It is given that out of 40, total 5 specimen are selected.
Thus, the number of ways in which 5 specimens are selected from a given sample of 40 is given by
Number of specimen with certain trait is equal to 3.
Now, total 5 specimen are selected out of which one specimen is selected from the set of specimen that has certain trait (i.e out of 3) while the remaining four specimen will be selected from the rest 
specimen.
Thus, the probability of choosing only 1 of the 5 specimens with the trait is equal to
Hello. Giraffes with longer necks survive compared to those with shorter necks because of natural selection. Over time, natural selection favors the traits that would make a species thrive better in the environment. Giraffes with short necks won't have access to that much food compared to those with long necks thus they eventually died out.
ANSWER: natural selection.
Answer:
1. Space-filling
2. Ribbon model
3. Wireframe
4. Simple shape
5. Simplified diagram
Explanation:
"attached is the question"
A protein can be visualized using different types of models. The models you use will depend on what you want the viewer to understand.
A space-filling model would show all the atoms that composes a protein. This type of model makes use of spheres, emphasizing the globular structure of the atoms. They are proportional to the actual size of the atom they represent. Each type of atom is a different color. Even the distances of the spheres are proportional to its size to help viewers better see the actual shape of the protein.
Ribbon model is also a 3D representation of a protein. It shows the only the backbone of the protein. It highlights the folds and coils in a protein, generally the organization. Some versions show the α-helices as ribbons and β-strands are shown as arrows.
Wire frame model is like the ribbon model but it also shows the side chains. It shows the different atoms that are involved. Thin wires show the bonds made between the atoms and the wires bend show the relative location of the atoms.
A simple shape focuses more on the function of the protein overall rather than the internal structures. The shape does not represent a particular protein, merely using a general shape to represent a protein.
A simplified diagram shows more detail than the simple shape. It shows the internal structures as well but like the simple shape model, it focuses more on the function of the protein. A version of it is a solid shape, which does not show the internal structure.
