Setler [38]
The answer should be A, inside the bag.

Permeable means allowing certain material to pass through. So if it's permeable to water and iodine, it means it can allow water and iodine to pass through the bag, but doesn't allow starch to go in.

Because iodine can pass through the bag, it can get into the bag filled with starch. But since starch couldn't diffuse out of the bag, the color change is only can be observed inside the bag. When no starch is gone out from the bag, there is no color reaction in the rest of the beaker.

So that answer is A.

All of the following are transmembrane pumps that facilitate active transport except?
BigorU [14]

Answer:

b) Channel pumps

Explanation:

The channels are the transmembrane proteins that serve in the passive transport of substances down the concentration gradient. The channels can be gated or non-gated. The gated channels are opened and closed in response to certain stimuli such as electrical change.

For example, aquaporins are the gated water channels that transport the water across the plasma membrane. The process is driven by the osmotic gradient and does not use the energy of ATP.

Plants and animals that lack color are commonly called albinos. In corn plants, green (G) is dominant to albino (g). A student
Fittoniya [83]

(B) 25% GG, 50% Gg, and 25% gg

<u>Explanation:</u>

Given:

Green is dominant and is coded by G

Albino is recessive and is coded by g

Two corn plants that are heterozygous for color are crossed.

The heterozygous condition of the plant would be Gg.

The cross is shown in the table attached.

According to the punnett square drawn,

The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)

                                 = 25% GG , 50% Gg , 25% gg

Phenotypic ratio = 3 : 1 ( green : albino)

                           = 75% green, 25% albino
