Answer:
Different types of microscopes use different sources for magnification, have different levels of magnification, and can help in visualizing an object in two dimensions or three dimensions.
Thus, if the same object is observed under different microscopes the differences we can observe is the resolution, magnification, and plane (2D or 3D) of the object.
For example, a compound microscope can magnify up to 500x whereas stereoscopic microscope can only magnify up to 50x.
Following general conditions are necessary for natural selection to occur in population:
- More organisms are born than can survive.
- Organisms vary in their characteristics, even within a species.
- Differences in reproduction and survival are due to variation among organisms.
According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.
Galapagos Finches: The Galapagos finches studied by Darwin on his famous voyage are probably the most common example of natural selection.
Answer:
A tight junction is a watertight seal between two adjacent animal cells, which prevents materials from leaking out of cells.
Explanation:
Answer:
Mechanical barriers — which include the skin , mucous membranes , and fluids such as tears and urine — physically block pathogens from entering the body. Chemical barriers — such as enzymes in sweat , saliva , and semen — kill pathogens on body surfaces.
I’m pretty sure it’s D, sorry if I’m wrong, I looked it up and it said “ Speed, latitudes, and direction of the objects determines the path along, which, the Coriolis effect deflects moving objects”
