Three genes (A, B, and C) at three loci are being mapped in a particular species. Each gene has two alleles, one of which result
Mashcka [7]

Answer:

The correct answer is:

D. Gene A is assorting independently of genes B and C, which are linked.

Explanation:

According to the text it is possible to deduce that the first allele of gene A appears with allele of gene B or C half of times. On the other side alleles of genes B or C appear at the same time in 14.4% of the cases. This information shows how A is and independent variable and how B and C are related as they appear together as well.

Consider one such cell where the magnitude of the potential difference is 40 mV, and the inner surface of the membrane is at a h
GarryVolchara [31]

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

W=q.\Delta V

in which

W is work in Joules (J)

q is charge in Coulomb (C)

\Delta V 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

\Delta V = 40x10⁻³ or 4x10⁻²V

Calculating

W=q.\Delta V

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.
