If I breed a short for FF female with a short for Ff male then I will expect to see what type of offspring

Usimov [2.4K]

If being short is the dominant trait, then you should expect the offspring to also be short.

This is because the traits are spread out as four different possibilities. Either FF, FF, Ff, or Ff. If the dominant trait is being short, “F” then this would mask the recessive trait “f”.

Under certain circumstances, potassium ions ( K + ) in a cell will move across the cell membrane from the inside to the outside.

dexar [7]

Answer:

8.18 × 10 ⁻²¹.

Explanation:

The potential energy may be defined as the energy stored in the rest objects. This energy is important for the maintenance of the concentration gradient in the cell.

The change in the potential energy can be calculated as follows:

W = v2-v1 × q.

Here, the charge of the proton is considered because k+ ions has been used.

W= 0 - ( - 70. 5 mV) × 1.602 * 10^-19 C.

W= 8.18 × 10 ⁻²¹J.

Thus, the answer is 8.18 × 10 ⁻²¹.

Ray Of Light [21]

Explanation:

(3) active transport

The molecules would be moving against their concentration gradient from a region of low concentration to a region of high concentration.

While cells facilitate the transport of molecules via movement across the cell membrane, there many different mechanisms. These include passive diffusion, facilitated diffusion, and passive transport. However some very large molecules require specialized type of active transport, which requires energy in the form of ATP, in order to move substances across the membrane against their concentration gradient.

Active transport is a mediated process that requires an energy input and the use of specialized membrane proteins to move against the concentration gradient. These proteins require energy in the form of adenosine triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules to alter the spatial location of the molecule. For instance, with Na+, K+ pumps in cell membranes.
