The correct answer is (a.) True. The Large variation in a crop may be developed by employing asexual reproduction. Asexual reproduction is a type of reproduction in which the offspring came from a single organism and may inherit only the parent's gene, not fusion of gametes.
Phospholipids are a class of lipids that are a major component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic.////////
True. The chemicals they gave to the birds made them quite ill.
A) The answer is allosteric interaction where activators or repressors bind to a protein, other than the protein active site, hence changing the protein conformation. This interaction occurs between the heme subunits of haemoglobin.
b) Through protonation. The amino group of the alpha subunits and the histidine C-terminal of beta subunits acquire H+ when the blood has low pH. Low pH in the blood is due to accumulation of carbon dioxide and consequent formation of carbonic acid. Protonation of the residues cause allosteric interaction, due to ionic interaction, of the subunits hence resulting to conformation change of haemoglobin between T-state and R-state
Most people afflicted with recessive disorder with recessive disorders are born to parents who are not affected at all by the disease. Most genetic disorders of humans are caused by recessive alleles. Dominant alleles on the hand cause lethal disorders, however they are less common compared to the recessive alleles disorders, this is because most individuals carrying a lethal dominant allele have the disorder and they die before pass it to the offspring, while the individuals with the recessive lethal genes are more likely to be healthy and reproduce.
