Answer:
I belleive A is the correct answer, here is why
Region: geography, regions are areas that are broadly divided by physical characteristics, human impact characteristics, and the interaction of humanity and the environment.
If that is correct then it is compleetly possible for animals to migrate over different regions
The beauty of plants being the reason for faster blooming cannot be tested using the scientific method.
<h3>The scientific method</h3>
It is a rational order of steps through which scientific investigations are conducted.
Beauty is a relative term and can be generally subjective. What is beautiful to one person might not be beautiful to others.
If we say that the lilies bloomed first before the asters because they are more beautiful, it will be difficult to categorize beauty into a metric variable, and thus, cannot be scientifically tested.

The Sample Size formula, also known as the Cochran Formula, allows for calculation of an ideal sample size. Below, I have inserted a picture of the formula, where it’s variables are as follows,
N=population size
E= margin of error
Z=z-score
Complete question:
If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.
Answer:
CC - homozygous dominant
cc - homozygous recessive
Cc - carriers
cc will have the phenotype
Explanation:
Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.
Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease
In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype
