Answer:
The flower colour ratio obtained is: Blue : Purple = 3 : 1.
Explanation:
- According to the question,
- the genotype, AABB or AaBb or AABb or AaBB gives blue phenotype.
- the genotype, AAbb or aaBB or Aabb or aaBb gives purple phenotype.
- Red phenotype is for the aabb genotype.
- As only the presence of dominant allele is mentioned but whether it is homozygous or heterozygous is not mentioned, in 1. we consider that presence of a single dominant allele A or B in either locus is capable of showing a blue phenotype, irrespective of the nature of the other allele.
- In 2. we consider that the presence of a single dominant allele, A or B in one locus with recessive pairs of alleles in the other locus is sufficient to develop the purple phenotype.
- The aaBb individual will produce the gametes: aB, ab.
- The AABb individual will produce the gametes: AB, Ab.
- Crossing them,
aB ab
AB AaBB AaBb
(Blue) (Blue)
Ab AaBb Aabb
(Blue) (Purple)
- Of the offspring obtained, 3 have blue phenotype and 1 has purple phenotype.
- Hence, they have the following phenotypic ratio:
Blue : Purple = 3 : 1.

The answer is:
<em><u>Carbohydrates give our bodies energy like sugars, glucose, fructose, sucrose and lactose. When you eat carbs, your body breaks them down into simple sugars then are absorbed into your bloodstream</u></em>

Answer:
They found evidence of an impact crater in Mexico
Explanation:
The K-Pg boundary is the boundary between the Cretaceous period and the Paleogene period, but also marking the end of the Mesozoic era and the beginning of the Cenozoic era. This boundary is dated to roughly 66 million years ago. The K-Pg boundary is characterized with a mass extinction. The dominant organisms on Earth all died out, including the dinosaurs, both terrestrial and aquatic, as well as the flying reptilians, with only the birds surviving from that super-family. The reason for the mass extinction has been an impact with an asteroid or a comet, that was very large and hit the Earth where the Yucatan Peninsula in modern day Mexico is located. The impact was devastating, with heat waves, tsunamis, earthquakes, triggering of the majority of the volcanoes, wildfires, all combined managed to devastate the environment, thus big portion of the species living in it as well. The lucky survivors were smaller organisms, and the mammals turned out to be the most successful in occupying the empty niches and have became the dominant organisms on the planet.
