In biology, a dichotomous key helps to identify and classify organisms based on similar features and structures
What is a dichotomous key?A dichotomous key is a tool used in biology to identify organisms based on similarities in their structure and function.
Organisms with similarities in their structure and function will be placed under the same category and any difference will be used to separate them.
For example in the dichotomous key for Shark, the features:
Fish with long tubelike body will identify sharksFish with body shape not tubelike will be used to separate fishes that are not shark.Therefore, a dichotomous key helps to classify organisms based on similar features and structures.

In this question we will describe the management goals of maximum sustainable yield, ecosystem-based management and adaptive management.
What is a sustainable management plan?A sustainable management plan aims to maximize forest production and minimize damage to the remnant responsible for the productive, structural, functional and genetic support of the exploited forest.
What is ecosystem-based adaptation?Ecosystem-based adaptation protects vulnerable communities from extreme weather while providing a variety of crucial benefits for human well-being, such as clean water and food.
What is Adaptive Management?Adaptive Management is a management approach developed to provide organizational systems with a greater degree of adaptability, seeking to provide means to increase the speed of response to environmental pressures and improve the quality of this response.
With this information, we can conclude that the disadvantages of these methods are that they will bring harm to the affected ecosystem.

In guinea pigs, the allele for black fur (B) is dominant over the allele for white fur (b). A black male guinea pig is mated to a white female guinea pig. The offspring were 7 black and 6 white guinea pigs. What are the genotypes of the parents?
Answer:
Male: Bb
Female: bb
Explanation:
1. I made punnet squares to test each genotype pairs:
BB (black male) x bb (white female)
Bb (black male) x bb (white female)
** B is dominant over b so if Bb, black will be expressed
3. I calculated the percentage of each phenotype to see if it matched the the number of white and black guinea pigs produced. I found that Bb x bb had 50% chance for white guinea pigs and 50% chance for black guinea pigs, which is about the same in the scenario above (7 black, 6 white).
4. I infered that the male black guinea pig's genotype is Bb and the female white guinea pig's genotype is bb.
