Answer: Definition and models Contamination alludes to the presence of a substance or substances in the climate that is unsafe or harmful. The substances or poisons might be hurtful to human wellbeing, different creatures, and plants. When something hurtful enters the climate at a quicker rate than it tends to be scattered, there is contamination. or Contamination is that the presentation of hurtful materials into the climate. These unsafe materials are called toxins. Poisons might be normal, as volcanic debris. they'll even be made by human activity, similar to waste or overflow created by industrial facilities. Contaminations harm the norm of air, water, and land. Explanation: Both describe what pollution means I hope this helps you
Sometimes the cells exit the cell cycle usually from G1 phase enter the G0 phase in the phase the cell do not copy their dna
Answer:
Stronger; a hydrophobic has lower dielectric constant. The lower the dielectric constant of the interior, the stronger the ionic interactions.
Explanation:
Ionic interactions are the electrostatic interactions between the oppositely charged ions. The strength of ionic interaction depends on the magnitude of the charges on the ions, the distance between the charged groups and the dielectric constant.
Here, the dielectric constant is the property of the medium in which the ionic interactions are taking place. Dielectric constant represents the number of dipoles present in the medium or solvent. A medium with higher dielectric constant would attract the oppositely charged ions towards its own dipole and would thereby, make the ionic interaction between the ions weaker.
Given that the ionic bonding between substrate and enzyme is taking place in the hydrophobic interior, ionic interactions would be stronger since the hydrophobic medium has a lower dielectric constant.
The lower number of the electric dipoles or their absence in the hydrophobic interior would not attract the oppositely charged groups of substrate and enzyme towards its own dipoles as the water with higher dielectric constant would have done. This would allow stronger ionic interaction between the substrate and the enzyme.
During interphase, the cell spends most of it's time in interphase duplicating it's DNA, growing, and carrying out it's regular function.
