One consequence of CFCS pollution is increased rates of skin cancer in humans.
Cholofluorocarbons cause the breakdown of the ozone layer that protects the earth from the sun's ultraviolet radiation. Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are brojken up by ultraviolet radiation, releasing the chlorine that catalytically destroys ozone.
Answer:
Adaptive defenses include both humoral and cellular immunity.
Explanation:
The innate immune response is the non-specific immune response and serves to provide an immediate and general immune response. The adaptive immune responses are the specific immune responses. Adaptive immune responses include cell-mediated immunity and antibody-mediated immunity.
Cell-mediated immunity includes T cells (cytotoxic and helper T cells) while antibody-mediated immunity includes the production of antibodies from B cells. Binding of antigen to B cells is followed by their transformation into plasma cells and produce antibodies. Some of the activated B cells form memory B cells that are responsible for quicker and strong secondary immune responses.
Answer:
A it investigates the super natural.
The correct answer is: about 99%.
The main difference between two random people’s genetic make-up issingle base pair differences, or polymorphisms (SNPs). There are about one SNP per 1000 bases. Since the human genome is about 3 Gbp long, about 3 million SNPs among two random people is present. SNPs may occur within coding sequences of genes, non-coding regions of genes, or in the intergenic regions.
Answer:
tRNA molecules bring a specific amino acid to the ribosome, according to the mRNA codon.
Explanation:
In the context of protein synthesis, an mRNA molecule contains the specific codons that encode the amino acids that will be part of the protein. The tRNA is in charge of bringing the amino acids to the ribosome, according to the specific information of the mRNA codons.
