Answer:
Explanation:
Staining is done for onion cells to visualize the cytoplasm of yellow and white onions because they are not pigmented. The staining of human cheek cells with methylene blue is necessary to stain the nucleus to get clear image of it under microscope because methylene blue binds to negative charge nucleic acids
While for leaf epidermal cells smears, staining is not necessary as they are visible under light microscope without staining and they also have pigmented materials inside them such as chlorophyll chloroplast. The cork cell is a non-living and have a cell wall whose structure is visible under light microscope.
Answer:
The Monterey pine and the Bishop's pine inhabit some of the same areas of central California. The Monterey pine releases pollen in February, while the Bishop's pine does so in April. This is an example of <u>temporal</u> isolation.
Explanation:
Temporal isolation is a form of reproductive isolation in which two or more species reproduce at two separate times.
<u>For example:</u> Northern america leapord frog mates in April and North America Bullfrog mates in july.
As in the given scenario, reproductive isolation is occuring in which two species (Monterey pine and Bishop's pine) are reproducing (producing pollens) at two separate times(February and April). Hence it is an example of temporal isolation.
