Answer:

spheres of Earth are represented in a tropical rainforest are

1. BIOSPHERE

2. HYDROSPHERE

3. LITHOSPHERE

4. atmosphere

Explanation:

Biosphere :The biosphere includes all life on Earth - plants, animals and humans. Most of what is studied in Life and Living is about the biosphere. The biosphere also includes life in the oceans, and under the soil. For example bacteria living on decaying plant material and the smallest sea creatures and plants are part of the biosphere.

Hydrosphere: The hydrosphere includes all water on the planet - the oceans, lakes, rivers, groundwater, rain, clouds, glaciers and ice caps. About 70% of the surface of the Earth is covered with water. The oceans contain most of this water, with only a small portion of it being fresh water. All the water on Earth forms part of the hydrosphere.

Atmosphere:The atmosphere includes all the air above the surface of the Earth all the way to space. All the gases that are present in the air are included in the atmosphere. Most of the atmosphere is found close to the surface of the Earth where the air is most dense. The air contains 79% nitrogen, less than 21% oxygen, and a small amount of carbon dioxide and other gases

Lithosphere: The lithosphere includes the Earth's crust and the upper part of the mantle. All mountains, rocks, soil and minerals included in the Earth's crust are part of the lithosphere. Even the seafloor is part of the lithosphere, because it is also made up of sediments of sand and rock.

Flura [38]

Answer:

assuming the

1.Cc represent creepers ( since creepers never breed true this is the likey representation,)

2. nn represents normal.

If these are crossed the F1 progeny are;

Cn and Cn= creeper

nc and nc = normal 50/50 % ratio.

However. if the two creepers(Cn and Cn ) from above are self-crossed in the F2 to give two creepers and a normal progeny .The creeper traits is expected to be dominant; while the recessive to be lethal, The normal birds nn, is expected to be homozygous recessive for the trait .
