The team of Hunt had designed an experiment to test the hypothesis of the effect of BPA on mice. The daily doses of BPA was administered into the female groups of mice for 3, 5 and 7 days and then the genetic abnormalities which occured during meiosis, chromosome division or egg formation were studied.

The steps followed in this experiment in order are as follows:

  • Observation- The mice eggs in plastic cages when washed using harsh soap showed problems during the cell division stage which caused genetic abnormalities.
  • Question- If the bisphenol A from the plastic affected mice in the damaged cages.
  • Hypothesis- If the frequency of the genetic abnormality was affected by the exposure to bisphenol A.
  • Prediction- The level of exposure of mice to bisphenol A was proportional to the increase in genetic abnormalities.

sineoko [7]

Answer:

A. Actin filaments and microtubules

B. intermediate filaments

Explanation:

Actin filaments and microtubules are two major building blocks that form part of the cytoskeleton in all eukaryotic cells. Both actin filaments and microtubules play a fundamental role in the dynamics of the cytoskeleton, and they are involved in many essential cellular processes including, among others, mitosis, cytokinesis, intracellular transport, cell signaling, etc. Moreover, intermediate filaments are very stable structures found in animal cells, where they extend from a ring around the cell nucleus to the plasma membrane in order to provide consistency and shape to the nuclear envelope.

Plastics, synthetic fabrics, and synthetic rubber are composed of chemicals that are derived from
SVEN [57.7K]
Petroleum Products

Petroleum and its products are mainly composed of carbon polymers (chains), as the backbone, with different structural and functional groups. Plastic, for example, is made of polypropylene and polybutylene which is mainly made of carbon atoms, whose monomers are linked in a chain to form polymers that make up the products.
Synthetic rubber on the other hand is made of copolymers of carbon and other addictives such as styrene. Synthetic fiber is made of nylon that is composed of a copolymer between carboxylic acid and amides.
