Answer: There are two ways to determine the age of a dinosaur fossil. One is called relative geologic time, which involves deciding whether one dinosaur fossil is older or younger than another. Geologists then measure the proportion of parent and daughter atoms present in the ash crystals to determine the crystal's age.
Explanation:
Answer:
The function of biomolecule inside our body system fully depends on the structure of that biomolecule.It is because the functional groups that participate in a chemical or biochemical reactions are arranged in a specific array in the structure of that biomolecule or macromolecule.
Explanation:
a enzyme structure/catalysis Enzymes are proteinecious in nature.Enzyme contain various amino acids in its active site such as histidine,serine,glutamic acid etc The amino acids of the active site of that enzyme interact with the substrate resulting in the formation of the product.
b mRNA structure/protein synthesis mRNA or messenger RNA consist of nucleotide sequence.The 3 concequetive nucleotides of an mRNA is termed as codons.Each codon codes for specific amino acid.The so formed amino acid linked with the adjacent amino acid by peptide linkage.
c cell membrane structure and signal transduction cell membrane contain various surface protein that act as receptor to detect signals by binding with signaling molecule during signal transduction process.
Answer:
The correct statements are A negative feed back regulation if free fatty acid accumulate C targeting the acetyl CoA transport shuttle in the mitochondrial membrane
Explanation:
The beta oxidation of fatty acid can be regulated by several following ways.
A The accumulation of free fatty acids exerts negative feedback during beta oxidation of fatty acids.As oxidation of fatty acids result in the breakdown of complex fatty acids in free fatty acids and acetyl CoA,the accumulation of free fatty acids lowers the rate of beta oxidation of fatty acid.
C The targeting of end product of beta oxidation that is acetyl CoA to the mitochondrial membrane also regulates the beta oxidation pathway.Because more the transport of acetyl CoA to the mitochondrial membrane more will be the rate of fatty acid break down by beta oxidation.
