How does adaption allow mice with the mutation to survive better in some areas

1 answer:

3 0

Answer: Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations. Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment. A mutation is an alteration of the DNA sequence.

A mixture initially contains A, B, and C in the following concentrations: [A] = 0.350 M , [B] = 0.650 M , and [C] = 0.300 M . Th

Answer: The value of equilibrium constant, $K_c$ for the given reaction is 12.85.

Explanation:

For the given chemical equation:

$A+2B\rightleftharpoons C$

At t = 0 0.350M 0.650M 0.300M

At $t=t_{eq}$ (0.350 - x) (0.650 - 2x) (0.300 + x)

We are given:

Equilibrium concentration of A = 0.220 M

Forming an equation for concentration of A at equilibrium:

$0.350-x=0.220\\x=0.130$

Thus, the concentration of B at equilibrium becomes = $0.650-(2\times 0.130)=0.390M$

Equilibrium concentration of C = 0.430 M

The expression of $K_c$ for the given chemical equation is:

$K_c=\frac{[C]}{[A][B]^2}$

Putting values in above equation:

$K_c=\frac{0.430}{0.220\times (0.390)^2}\\\\K_c=12.85$

Hence, the value of equilibrium constant, $K_c$ for the given reaction is 12.85.

How could two species that evolved on separate continents have many similarities? Read More >>

Neko [114]

They could have similar environments which require them to adapt similar characteristics

for example the dolphin and shark are not related but due to their aquatic environment they have similarly shaped tails and fins

the process or species getting more similar over time is called called convergent evolution

Which of the following has the greatest mass? pls look at options

Rzqust [24]

Answer:

C.) One mole of mercury

Explanation:

You can determine which has the greatest mass by identifying each of their atomic masses. The atomic mass represents the mass of an element per 1 mole.

Gold (Au): 196.97 g/mol

Mercury (Hg): 200.59 g/mol

Barium (Ba): 137.33 g/mol

In this case, one mole of mercury has the greatest mass.
