The right option is; dark-field microscope
A light microscope that makes the specimen appear light on a dark background is called a dark field microscope.
Dark field microscopes are light microscopes that are used in different ways to clearly view various specimens that are unstained, transparent, and hard to see using a light field unit. Dark field microscopes are very effective because they show the details of unstained and live samples. It is also very simple to use, and inexpensive to set up.

Answer:
there is a 25% chance that the parents (both Hh) will have a child that does not have the disease 
Explanation:
 This would be the dichotomous key:
 
 | H | h

Answer:
Based on the data in Table 1 and the biomass of the very large animals eaten by the lions, predict the likely effect on both the lions and leopards if the availability of the very large animals becomes limiting in the reserve. After analyzing the data, the scientists claim that the leopards and lions coexist in the reserve through the use of niche partitioning. Use evidence from the data provided to support the scientists’ claim.
