Answer:
This research employed the population density, building density and building coverage ratio as independent variables, whereas Escherichia coli is a dependent variable.
Answer:
b
Explanation:
its b because it doesnt say any else then 15 or any clues so its tryna trick u
One reason could be that they do not have most of the seven characteristics of life (reproduction, homeostasis, heredity, response to the environment, growth, cellular organization, and metabolism.)
Butane, C₄H₁₀ will undergo only London dispersion forces when interacting with other molecules of the same kind.
London dispersion force:
- The weakest intermolecular force is called the London dispersion force.
- When the electrons in two nearby atoms occupy positions that cause the atoms to temporarily form dipoles, the resulting transient attractive attraction is known as the London dispersion force.
- There are instances when this force is referred to as an induced dipole-induced dipole attraction.
Butane molecules only exhibit London dispersion forces because they are non-polar and have a symmetrical distribution of electron density.
<u><em>Butane:</em></u>
- It is a covalent non-polar molecule. Every C-C and C-H bond is non-polar. This is because there is little or no electronegativity difference between C and C in C-C bonds and none between C and H in C-H bonds.

Polar bonds are when negatives and positives are attracted to eachother
