Answer:
The sensitization and awareness campaign by Teddy's organization was aimed to prevent greenhouse effects by preserving the integrity of the ozone layer in deflecting the dangerous ultraviolet radiation from the sun.
Explanation:
Products such as aerosols, refrigerators, and other substances that can release Chlorofluorocarbons (CFCs) had been banned due to their bye product of CFCs which had been studied to be harmful to the ecosystem, especially the stratosphere.
The released CFCs are volatile and escape faster due to their low relative density. Therefore, they tend to get into the upper atmosphere within a couple of minutes. When CFCs and Ultraviolet radiation reacts, it leads to the formation of mono oxides of chlorine and bromine. These fragments (Cl2O and Br2O) are capable of reducing the protective ozone shield into ordinary oxygen, which cannot prevent the penetration of harmful ultraviolet radiation into the earth, which cause mutation of DNA and destruction of protein content of the animals and plants on the earth, and finally to cancer and other genetic mutation problems.
Bc yarn and hair is very identical so therefore hair would be a substitute for yarn

Answer:
D. 100%
Explanation:
In humans, males have only one copy of the X chromosome in their cells. Therefore, human males express all the X-linked genes present on their X chromosomes irrespective of the recessive or dominant nature of the allele. This occurs since males do not have one more copy of the X chromosome to carry another allele for the gene. So, all the X-linked alleles present on the X-chromosomes of the human males are expressed.
For example, human males with genotype X^cY and X^hY express colorblindness and hemophilia respectively. Though, human females express these recessive X-linked disorders in homozygous genotype only.
