The trick here is to understand the definition of each of the cellular transport or function mechanisms listed. These are some interesting (and strange) analogies!

Facilitated Diffusion
This is when a mechanism assists in diffusing (spreading) some material into an environment. The dog on the wagon going through a spring loaded door would shoot it out into the environment. This is an odd analogy but Point 3 would be the one.

Active Transport
Is when energy is expended to transport molecules somewhere against a concentration gradient or some other barrier. Examples include transporting molecules across a cell wall. The best analogy is the dog being dragged into a bathtub (Point 1).

Phagocytosis
This is when a larger cell consumes a molecule often like eating. This matches to point 2 - the child eating the doughnut.

Passive Diffusion
Is when a concentration of molecules naturally diffuse into an environment. This suits point 5 - the crowded room full of people.

Pinocytosis
Is the budding of cell membranes to consume liquid in the surrounding environment. I guess a woman drinking tea is the closest analogy listed (Point 4).

Suppose you have monohybrid flowers in your garden and find that they produce black seeds to brown seeds in the ratio of 3:1. If

Dvinal [7]

Hybrid = having one recessive and one dominant allele
This means that all of the flowers must have the genotype Bb.
Knowing this, let's make a Punnet Square.

$\begin{tabular}{ l c } & B \ \ \ \ b\\ B & \boxed{BB}\boxed{Bb} \\ b & \boxed{Bb\ }\boxed{\ bb} \\ \end{tabular}$

As you can see, 3 of these are going to have the dominant trait and 1 is going to have the recessive trait. This corresponds to our 3:1 in our question, meaning that the black seeds must be dominant and the brown ones recessive.

Because they are dominant, the genotype for black seeds could be BB or Bb.

Pea flowers may be purple (P) or white (p). Pea seeds may be round (R) or wrinkled (r). What proportion of the offspring from a

soldi70 [24.7K]

Answer:

The correct answer is c. 3/16.

Explanation:

In the given question two traits being studied, the traits are flower color and seed shape.

This is a typical Mendel’s dihybrid cross. According to the question purple colour (P) and round seed (R) are dominant traits.

When heterozygous purple-flowered (Pp), round-seeded (Rr) individuals are crossed, four different types of plants are produced phenotypically in the ratio 9:3:3:1.Out of 16 offspring, 9 are purple flowered, round seeded pea plants, 3 pea plants are white-flower with round seed, 3 are purple- flower with wrinkled seed and 1 pea plant is white-flowered with wrinkled seed pea plant is produced.
