Stratosphere is the majority of Ozone that protects against the high energy radiation of the sun. Ozone is an allotrope of oxygen. It is the necessary protective component of upper atmosphere but considered a pollutant in the atmosphere.

In troposphere temperature increases with increasing ltitude. Ozone was discovered in 1913 by French Physicists called Henri Buisson and Charles Fabry. 97 TO 99 percent of sun’s medium-frequency ultraviolet light are absorbed on the Ozone layer.

In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted po

kifflom [539]

Answer:

The phenotypes are as follows

Purple, full- 9

Purple, constricted- 3

White, full- 3

White, constricted- 1

Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.

Explanation:

This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).

In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1

Purple color, full pod- 9

Purple color, constricted pod- 3

White flower, full pod- 3

White flower, constricted pod- 1

Explanation:

Mediterranean fruit flies are also called as medfly. They are a type of pests that are yellow and brown in color and are originated from Sub- Sahara Africa and also found in California, Texas and some other places.

When Matthew Gage analyzed then, he found the males that mate alone produce fewer sperms while those mates in the presence of other males produce more sperms.
