To support abiotic and biotic life forms.
Answer:
Dogs smell a lot better than humans, because they have more complex nose structures that allow them to follow any scent
Having 2 chromosomes that are divided will give you a chance of getting one of them of 50%. Calculation of the probability as follows:
<span>Probability = 0.5^12</span>
<span>Probability = 0.00024</span><span>
So, you have a chance of 1 in 4167. Hope this answers the question.</span>
I believe that the answer to the question provided above is that the <span> time frame is considered rapid environmental change is the modernization period.</span>
Hope my answer would be a great help for you. If you have more questions feel free to ask here at Brainly.
Answer: W = 6.4x10⁻²¹J
Explanation: <u>Work</u> is the energy transferred to or from an object due to the application of a force along a displacement.
The ion Na is gaining energy to move from a lower potential to a higher one.
For this to happen, the work done is calculated as
in which
W is work in Joules (J)
q is charge in Coulomb (C)
is potential difference in Volts (V)
The ion Na has one positive charge. In coulombs, the charge is
q = 1.6x10⁻¹⁹C
The potential difference in Volts is
= 40x10⁻³ or 4x10⁻²V
Calculating
W = 1.6x10⁻¹⁹. 4x10⁻²
W = 6.4 x 10⁻²¹ J
The work done to move an ion of sodium from the exterior to the interior is 6.4 x 10⁻²¹ J.
