what are the answer choices
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.
The answer is A. Can mate with each other and produce fertile offspring.
Answer:
The correct answer is C. the size of the algae population .
Explanation:
An ecosystem is made up of biotic and abiotic factors. Biotic factors are the living components of an ecosystem that impact the ecosystem and abiotic factors are the non- living components that have their own impact on the ecosystem.
So according to the definition of biotic factor algae is the biotic factor in this question because algae is a living component of the ecosystem that influences the ecosystem by providing food to the corals.
So by providing food algae supports the coral's ecosystem and coral provides a home to algae to grow. In the ecosystem, both biotic and abiotic factors interact with each other.
So the correct answer is C. the size of the algae population.
Because when the DNA replication occurs, it will first uncoiling. And each strand will be a template for replicating. So the new DNA will have one strand from the origin DNA and one strand from newly synthesis. That's the reason of semi-conservation.
