Answer: D) The amount of air in a room never changes.

Explanation: Equilibrium is defined as the state in which the concentration of reactants and products is constant or the rate of forward direction is equal to the rate of backward direction.

a) The percentage of nitrogen gas in a room decreases steadily: the amount decreases that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.

b) A blade of grass grows taller : the plant gets taller that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.

c) The amount of water in a cup decreases as it evaporates: The amount of water is decreasing that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.

d) The amount of air in a room never changes: the amount of air does not change as the amount of air leaving the room is same as that of the air entering the room and hence the  reaction is in equilibrium.

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

Match the description to the type of energy.
attashe74 [19]

Answer:

1)diaphragm vibrations- sound waves

2) Changing magnetic fields- Electrical energy

3)sound waves- Mechanical energy

Explanation:

A changing magnetic field induces an electromotive force and then an electric field which contains electrical energy

Sound energy is a form of energy that can be heard by humans. Sound is an example of a mechanical wave because it consists of physically oscillatory elastic compression.

A diaphragm is a thin surfaced cone used to produce sound. It is caused to vibrate using electromagnetic energy.
