For a gene that determines wing color in butterflies, there are three possible genotypes: BB (blue wings), bb (white wings), and

Bb (white wings with blue blotches). A sample of 100 butterflies was collected, and the following was observed:
Wing Color Number of Butterflies
blue 60
white with blue blotches 30
white 10


What is the frequency of the Bb genotype in this population if it is in Hardy-Weinberg Equilibrium?

Answer: The frequency of the b allele is calculated as follows: since there are 2 alleles in each organism, total number of genes is 200. The number of white alleles is 10*2+30 (since there are 2 copies of the alleles in white organisms and 1 copy of the b allele in the white wings with blue blotches). So the total number of white alleles is 20+30=50 white alleles. The frequency of the white allele is then 0.25. So the frequency of the blue allele is 1-0.25=0.75. Since heterozygous term is 2*p*q, the frequency of the Bb genotype is 2*0.25*0.75=0.375. Hope that helped!

Answer:

DNA or RNA: Nucleic acid

Starches and sugars: Carbohydrates

Antibodies: Proteins

Can be utilized for energy if sugars are not available: Lipids

Hydrophobic part of the plasma membrane: Lipids

Glucose and sucrose: Carbohydrates

Explanation:

The DNA or RNA can be described as molecules made up of nucleic acids.

Carbohydrates can be described as biological molecules made up of carbon, hydrogen and oxygen. For example, starches, sugars, glucose, sucrose etc

Antibodies can be describe as a type of proteins which provide the body with immunity.

Lipids or fats are the alternative source of energy if carbohydrates are not present.

The hydrophobic tail of the plasma membrane is made up of fatty acid molecules which are lipids.

We live in the Cenozoic era, and scientists know more about this era and the epochs it's divided into than any other time period
mel-nik [20]

Answer:

D. We know more about the Cenozoic era because this the most recent time period in the history of the Earth, and we have more information available to study.

Explanation:

The Cenozoic era is the era that is by far the best studied and known by the scientists. The main reason for this is that this era is the most recent one, and it is actually the era we live in. Because it is the most recent era, the Cenozoic is abundant with lot of evidence of what has happened in it. The fossil records are very rich as the fossils didn't had that much time to totally decompose. The rock layers are much younger, so they contain much more detailed evidence of the plant life, climate, changes in the environment. The oceanic crust is also in abundance, which is not the case with the other eras as the oceanic crust is constantly suducted.
