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 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.

An enzyme that copies dna to make a molecule of rna is:.
Answer: An enzyme that copies DNA to make a molecule of RNA is RNA polymerase.
Answer:
RNA polymerase
Explanation:
RNA polymerase has many important roles inside of an organism and is a very complex enzyme. One of the most common roles "RNA polymerases" has, is that it is able to copy DNA to then make an RNA molecule. Another common role the RNA polymerase has, is that it helps maintain the organism's metabolism. Which means the enzyme itself helps the chemical processes within an organism be completed in order to keep that organism from dying.

Which is a cause of drought?
A.High precipitation levels
B.low water demand
C.low precipitation levels
D.high water demand
Drought is the time period where is marked by dry conditions which is caused by the low precipitation levels. Thus, the correct option is C.
What is Drought?Drought is a prolonged dry period in the natural climatic cycle in an environment that can occur any geographic location in the world. It is a slow-onset disaster which is characterized by the lack of precipitation, resulting in a water shortage condition. Drought may cause a serious impact on the overall health, agriculture, economies, energy and the environment of an area.
Drought is mainly caused by a lack of rainfall, which causes serious water shortage. This condition can be fatal. Unlike the other extreme weather events that are more sudden, like that of earthquakes or hurricanes, droughts can happen gradually.
Therefore, the correct option is C.

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.

respiration, and ATP.
Answer:
Cellular Respiration Photosynthesis
The entire process occurs in Mitochondria. The entire process occurs in Chloroplasts.
Glucose and oxygen are the reactants of this process. Carbon dioxide, water and light energy are the reactants of this process.
