Answer:
1.5mm
Explanation:
According to this question, Mary is trying to view 5 pollen grains under her microscope. She found out that the 5 pollen grains each with a diameter of 0.3mm could fit along the diameter of the field of view of her microscope.
This means that the diameter of the field of view of Mary's microscope can be calculated as follows:
Diameter of each pollen × no. of pollen that fit in
= 0.3mm × 5
= 1.5mm
Hence, the diameter of the field of view of Mary's microscope is 1.5mm.

Crayfish are invertebrates which means they don't have a backbone. They are also arthropods, which means that they have a protective exoskeleton on the outside of their body. Other arthropods include insects, spiders, and centipedes. Crayfish continually shed their exoskeleton and regrow a new one. During this transition is when they are most vulnerable to predators because they aren't protected by their outer shell.
Crayfish are found all over the world in many different freshwater environments, such as rivers, creeks, springs, and swamps. But this doesn't necessarily mean that you will be able to find them. They are somewhat cryptic because they dig out homes for themselves under rocks and blend in well with their environment. Crayfish will ardently defend this dwelling against intruders using their strong front claws
