Answers

Meiosis I is dedicated to forming two Haploid(half chromosome) cells bby separating each pair of chromosomes (one of each type in each cell) and the recombination, or shuffling of genes on each chromosome with its pair by crossing over, While Meiosis II is meant to split the individual chromatids in the haploid cells to create a total or 4 daughter cells

Answer:

A

Explanation:

While studying enzyme kinetics in the lab, a scientist observed that the rate of a reaction involvingenzyme amylase increased as the concentration of starch increased. With further increase in starchconcentration, the amylase activity did not change. Why did this happen

Answers

  B. This is because there were still active sites available for the starch substrate to bind to when the concentration was initially increased (the reaction will have been first order with respect to the concentration of starch). However, at a certain concentration, all the active sites of the enzymes will be full so there will be no active sites available for the starch molecules to bind to (the reaction is now zero order with respect to the concentration of starch). i need brainliest answer to rank up plzzzz help
