Stolb23 [73]
Hello!

<span>The position of the equilibrium for a system where k = 4.6 × 10-15 can be described as being favored to the left; the concentration of products is relatively small.

For a reaction where A produces B, the chemical equation is the following:

A </span>⇄ B

The equilibrium constant expression is the following:

k= \frac{[B]}{[A]}

From this equation, we can see that when the constant is small, as in the case of the exercise, the concentration of products is also small, and the equilibrium is favored to the left. 

Have a nice day!

Which trait is most likely a result of artificial selection
ycow [4]

Answer:

Explanation:Artificial selection is distinct from natural selection in that it describes selection applied by humans in order to produce genetic change. When artificial selection is imposed, the trait or traits being selected are known, whereas with natural selection they have to be inferred. In most circumstances and unless otherwise qualified, directional selection is applied, i.e., only high-scoring individuals are favored for a quantitative trait. Artificial selection is the basic method of genetic improvement programs for crop plants or livestock (see Selective Breeding). It is also used as a tool in the laboratory to investigate the genetic properties of a trait in a species or population, for example, the magnitude of genetic variance or heritability, the possible duration of and limits to selection, and the correlations among traits, including with fitness.

Describe a process in which energy changes form at least two times explain how the law of conservation of energy applies to the
Dmitry_Shevchenko [17]
A pendulum.  Hold it high and it has potential energy but no kinetic energy because it is still.  As it moves down when you drop it, it changes to kinetic energy and moves faster and faster until it's at the bottom where it has no potential energy.  However, it still has momentum, so now it is changed to potential energy as it moves up the other side
