Answer:
1) Pentane 2) 2-Pentene
Explanation:
Both molecules have five carbons so you will add thhe prefix "pent-" and the first molecule only has single bonds so it will end in "-ane" because is it an Alkane. The second hydrocarbon has a double bond; therefore, it's a Alkene resulting in the ending of "-ene". BUT the double bond is located on the second carbon; therefore you must add "2-" before the name.

Answer:
cladistic analysis
Explanation:
Cladistic classification is classification in which organisms are put in group based on their shared characteristics and the most recent common ancestor. So, organisms of the same group are are closely related. Cladistic analysis are methods for the estimation of relationships among organisms and it includes the use of data on the traits of those organisms. The result of cladistic analysis is a diagram-tree which is called cladogram. Cladogram represents relations among organisms.
The question is incomplete. The complete question is:
Plasmodesmata are cell junctions that are found between ________.
a) adjacent animal cells in the same tissue type
b) individual cardiac cells in heart muscle tissue
c) the plasma membrane of actively dividing prokaryotes
d) adjacent plant cells
Answer:
d) adjacent plant cells
Explanation:
Plasmodesmata are the cytoplasmic channels that connect the adjacent plant cells together and maintain the continuity of their cytoplasm. These are the narrow channels with 20-40 nm diameter. Plasmodesmata serve the function analogous to the gap junctions of the animal cells. The presence of plasmodesmata between the neighboring plant cells allows the movement of molecules and ions between them. Plant cells can adjust the diameter of the plasmodesmata according to the requirement to allow the transport of substances across them.
The main function of the microscope is to see microscopic objects, or small objects so small the naked eye can't see it. It magnifies the object so our eye can see it.
<span>After discovering and improving the microscope, Robert Hooke discovered cells. This is just one example of how it changed the study of organisms. With the microscope, we could see and find microscopic life like bacteria and see the cells, shape, color, and other materials such as the organelles the organisms were made of.</span>
