The correct order given below shows the changes that occurs in a mice population in response to changes in their environment:

  • The population of mice is in an environment with many black rocks
  • Mice with black for are more likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have black fur
  • A sandstorm covers most of the population's environment with brown sand
  • Mice with black fur are less likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have brown fur

<h3>What is the correct order for natural selection in the desert environment given?</h3>

Based on the process of natural selection due to envrionmental pressures, the population of the mice in the desert changes as follows before and after the environmental change:

  • The population of mice is in an environment with many black rocks
  • Mice with black for are more likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have black fur
  • A sandstorm covers most of the population's environment with brown sand
  • Mice with black fur are less likely to survive and reproduce than mice with brown fur
  • After many generations, most of the mice in the population have brown fur

Therefore, the correct order shows the changes that occurs in a mice population in response to changes in their environment.

Anybody know chemistry Grahams law ?
sukhopar [10]
There is two different types but i’ll just do both meanings just incase.

Graham's Law of Diffusion: the rate of diffusion of one gas through another is inversely proportional to the square root of the density of the gas.

Graham's Law of Effusion: the rate of effusion of a gas is inversely proportional to the square root of the density of the gas.

hopes this helps..!

Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen
polet [3.4K]

Answer:

A. Whenever the population has increased, steel consumption has increased as well.

Explanation:

Based on the graph of US population and steel consumption, what could have led to the increase in steel consumption seen  on the graph is that whenever the population has increased, steel consumption has increased as well.

A critical look at the graph, you will discover that the population and the steel consumption are moving upwards (i.e they are increasing). It's seen that as the population increases, steel consumption increases. This is true because as the population increases, people are building houses, more transportation systems that require steel are being manufactured, more household utensils that are steel products are being fabricated etc; therefore the consumption of steel increases.

What energy transformations occur each time the skateboarder rolls up on the ramp? ( I will try to mark you ) (7th grade science
ZanzabumX [31]

Answer:

Kinetic energy is energy of motion. The faster skaters move, the more kinetic energy they have. In a halfpipe, energy is constantly transformed between potential (at the top) and kinetic (as they travel down the sides) as the skater goes back and forth between the ramps.

The equilibrium constant (K p) for the interconversion of PCl 5 and PCl 3 is 0.0121:
aksik [14]

Answer: At equilibrium, the partial pressure of PCl_{3} is 0.0330 atm.

Explanation:

The partial pressure of PCl_{3} is equal to the partial pressure of Cl_{2}. Hence, let us assume that x quantity of PCl_{5} is decomposed and gives x quantity of PCl_{3} and x quantity of Cl_{2}.

Therefore, at equilibrium the species along with their partial pressures are as follows.

                         PCl_{5}(g) \rightarrow PCl_{3}(g) + Cl_{2}(g)\\

At equilibrium:  0.123-x          x              x

Now, expression for K_{p} of this reaction is as follows.

K_{p} = \frac{[PCl_{3}][Cl_{2}]}{[PCl_{5}]}\\0.0121 = \frac{x \times x}{(0.123 - x)}\\x = 0.0330

Thus, we can conclude that at equilibrium, the partial pressure of PCl_{3} is 0.0330 atm.
