If a system requires 150 J of input work and produces 123 J of output work, what's its efficiency?

The efficiency of work is a dimensionless value, and is equivalent to the ratio of the actual work output to the theoretical work requirement. This can be calculated using the equation:

Efficiency = (actual work) / (work requirement) = 123/150 = 0.82

The higher the efficiency, the better performance is given by the system. In reality, efficiency is always lower than 1 which is the ideal value.

Large molecules, such as glucose, that cannot cross the lipid bilayer can still move across the membrane through a type of passi
harkovskaia [24]
Facilitated diffusion. It is a passive transport mechanism in which carrier proteins shuttle molecules across the cell membrane without using the cell’s energy supplies. Instead, the energy is provide by the concentration gradient, which means that molecules are transported from higher to lower concentrations, into or out of the cell. The carrier proteins bind to glucose, which causes them to change shape and translocate the glucose from one side of the membrane to the other. Red blood cells use facilitated diffusion to absorb glucose.

Each of two parents has the genotype green divided by brown​, which consists of the pair of alleles that determine eye color​, a
Liula [17]

Answer:

A)BB-Bg-Bg-GG

B)The probability is 25%

C)The probability is 75%

Explanation:

In order to solve this you just have to create a punnet square, where the parents are shown to both have brown and green coloured eyes genes, so it would be like this:

               Mother:      Brown                                 Green

Father↓  

Brown                      Brown-Brown                 Brown-Green

Green                      Brown-Green                  Green-Green

As the instructions say that if any kid had one green allele that would be the dominant, only the Brown-Brown will show the fenotype, so there´s 1/4 chance to happen, or 25%, the other probability of having green eyes is 3/4 or 75%

2 characteristics of bisexual flowers​
deff fn [24]

Answer:Bisexual flowers are complete flowers, containing both androecium and gynoecium in one flower. Therefore, bisexual flowers contain both stamens and pistils in the same flower. Hence, bisexual flowers are called hermaphrodite or androgynous flowers as well.
