4. Neurofilament proteins (NF-L, NF-M, NF-H) are found primarily near the MTOC in neuronal cells, where they stabilize the organization of the endoplasmic reticulum and Golgi complex. True or False
Homework Answers
True.
Neurofilaments are a class of intermediate filaments that play a role in structural integrity and organisation of the neuronal cells. Like other intermediate filaments, they provide anchorage and stabilization to cell organelles such as endoplasmic reticulum and golgi complex. Also it serves to reorganise the cells so that they can organise into tissue

It has been found that in acid solution (greater than 1 M H^+) the rate expression for the reaction of H_2O_2 with I' is of the form rate = k_2[H_2O_2][T] where k_2 = 0.25 L^2 mol^-2 s^-1 at 25 degree C Therefore the rate law over the whole range of acidity from very acid solutions to a neutral solution is given by a two-term rate expression: rate = k_1[H_2O_2)[I^-] + k_2[H_2O_2)[I^-)[H^+) where k_j has the value of 0.0115 L mol'1...

1.In early March, it was reported that two main strains of SARS-CoV-2 had been identified, termed S and L, with the S type being the less virulent ancestral form representing about 30% of prevalence and the more virulent L type having descended from the S type and representing about 70% of prevalence. However, the prevalence of the more virulent L type seems to have decreased after early January, and it is thought that this resulted from human intervention against this...
