This vacuole also perform other functions such as storage (water and other nutrients) and waste disposal. When this vacuole is damaged in plant cells, the cells may no longer be able maintain turgor pressure and store materials (water inclusive).

Reil [10]

Answer:

<u> Succession</u> refers to the process that facilitates plant communities gradually changing over a period of time in order to respond to their environment.

Succession can be described as changes that occur in an ecosystem in response to the changes in the environment or any other disturbances.

Succession can be of two types. 1. Primary succession 2.Secondary succession

Primary succession occurs on lands where there was no life before. With time, plants start to grow here and a community is developed.

Let Y = yellow and y = green, and R = round and r = wrinkled. You cross YYRR peas with yyrr peas. All of the F1 individuals are
lukranit [14]

Answer:

1/4

Explanation:

Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio.

YyRr X YyRr:

Let us break the dihybrid cross into individual monohybrid crosses.

Yy X Yy :

    Y     y

Y  YY  Yy

y   Yy   yy

2/4 or 1/2 of the offspring are heterozygous for the trait.

Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.

Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.
