Answer:
0.0025micrometer.
Explanation:
To calculate the actual size of the image, the formula to be used is
Actual size=Image size÷magnification.
The image size is 0.00005 wide
Magnification is 2000
First, convert the image size to micrometer.
=0.00005 × 1000000
50micrometers.
Actual size= 50÷2000
Actual size = 0.0025
The KT boundary marks a mass extinction event. the KT boundary is the time between the Cretaceous and Tertiary periods. An asteroid hit the earth at the end of the Cretaceous and that caused the end of the Cretaceous period. Before the KT boundary, pollen from angiosperms and gymnosperms is high. After the meteor hits the earth, a mass extinction occurs and the amount of pollen from gymnosperms and angiosperms decreases dramatically, while the amount of spores from ferns increases. During the Cretaceous period there were many species of gymnosperms and angiosperms but they disappeared at the KT boundary, when the asteroid hit the earth.

Answer:
it becomes a positive ion
Explanation:
that is because when it loses an electron, then it has one more proton in comparison with the total number of electrons making it a positive ion
Answer:
Both plant and fungal cells have a cell wall. The main difference between the fungal cell wall and the plant cell wall is that the plant cell wall is made up of cellulose whereas the cell wall of fungal cells are made up of chitin. Along with cellulose, the plant cell wall also comprises of hemicellulose and pectin.
