Genotypic ratio = 50% WW, 50% GW
Phenotypic ratios = 50% white, 50% appaloosa
<h3>Monohybrid cross</h3>
White horse genotype = WW
Appaloosa genotype = GW
WW x GW
GW WW GW WW
Genotype ratio = 50% WW, 50% GW
Phenotype ratio = 50% white, 50% appaloosa

Answer:
nutrients are recycled, but energy is not
Explanation:
In the flow of energy, the sun represents the maximum source of energy and this energy is converted into other forms, a transformation process where energy is not recycled but transformed into other forms. Already the flow of nutrients in an ecosystem occurs through biochemical cycles, where nutrients are used and recycled to be reused.
Explanation:
A=non-living because it doesn't perform metabolic activities
B=Living because it does metabolic activities
C= Living because it make food for it self
D= It is non-living because it doesn't perform metabolic activities

Answer:
The correct answer is option A) "Sequence of bases".
Explanation:
Even though DNA most of the time is comprised entirely of only four different nucleotide bases (adenine, thymine, guanosine and citosine), it is the sequence of these bases that allows DNA to carry a vast amount of hereditary information. The genes that carry the hereditary information are translated according to the sequence of the DNA bases. The information is translated by triplets of bases (codons) that correspond to different amino acids that are added to new synthesized proteins during translation.
Complete question:
A student is working on a lab where they are trying to identify an unknown substance. The student decides to smell the solution by taking a big breath over the test tube. They immediately start to cough and their lungs are burning.
Answer and Explanation:
Many chemicals might be recognized by their smell. Some of them might be inoffensive, some others might cause slight damage and some others might be very harmful to the person that inhales them.
In the exposed example, the solution probably damaged the respiratory tract, causing inflammation and irritation.
There are some issues to take into account to avoid an accident by inhaling a chemical:
<u>Precaution</u>:
- Study the security rules of the laboratory
- Always read the label of the substance
- Ask the teacher or the person in charge, about the correct procedure
- Proceed in the correct way, by driving the smelly vapors with your hand toward your nose. Never breathe directly over the test tube.
In case of accidents by inhaling you should:
<u>Response:</u>
- Take the affected person out of the laboratory
- Look for an airy place where the affected person might breath
- Call an emergency service
- Explain exactly what the affected person did and the chemicals that the person inhaled.
