Why are small quantities of chlorofluorocarbons so harmful to the ozone layer?

Biology
1 answer:
ikadub [295]3 years ago
8 0

Answer:

The chlorine from the chlorofluorocarbons reacts with free molecules of oxygen causing a stop in ozone production. ... Free oxygen atoms can replace the chlorine in chlorine monoxide, releasing a free atom of chlorine which can then recombine with an oxygen atom in ozone, destroying more ozone.

Leokris [45]

Insect hormones and their receptors are a focus in pest control and research. Hence, Option B is correct.

Some of the insect hormones such as ecdysone (molting hormone), JH (juvenile hormone) and their analogs can be used for biological  control of pests.

Option A: Hormone receptors are proteins that bind hormones and form hormone receptor complex to maintain cellular activities.

So Option A is incorrect.

Option B: Some of the peptide hormones used in pest control and research. So Option B is correct.

Option C: Peptide hormones interact with only cell surface whereas aminoacid derivatives and thyroid hormones directly interact with nucleus. so Option C is incorrect.

option D is incorrect.

Explain how genetic information is stored in DNA and how this information is used to make functional proteins.
AfilCa [17]

Answer:

The correct answer will be- codons and each codon specific for amino acids.

Explanation:

Deoxyribose nucleic acid is the genetic material of the organism which provides instructions for the organism.  DNA is made up of nucleotide monomers which are composed of five-carbon sugar deoxyribose, a phosphate group and four types of nitrogenous bases (adenine, guanine, cytosine and thymine).

It is the arrangement of these nitrogenous bases which provide codes to the organism as it forms mRNA molecule through transcription. The sequence of the nitrogenous bases in mRNA is read by the ribosome during translation.

The ribosome reads the bases in triplets called "codon" which code for a specific amino acid. If the sequence of the base changes, therefore, the amino acid also changes. These amino acids bond to each other by peptide bond and form a protein molecule.
