1. List 2 interactions between the earth spheres and the water cycle.
Harrizon [31]

Answer:

The carbon cycle, as the nitrogen cycle, occurs in all the spheres: Biosphere, Atmosphere, Geosphere and Hydrosphere.

Explanation:

Most Earth events involve interaction between multiple spheres. For example, rain is the movement of water (the hydrosphere) from the atmosphere to the lithosphere where it collects in lakes, rivers, or streams. Water is an important resource for inhabitants of the biosphere.

The Atmosphere-contains all the air in Earth's system. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. This sphere is also where weather occurs.

The nitrogen cycle occurs in all the spheres and ecosystems. It passes through rocks, water, atmosphere, plants, etc.

In atmosphere and biosphere: Nitrogen is about 78% of the gases in the atmosphere an it’s a essential component of the living organisms. It enters plants through the microorganisms that convert this nitrogen into ammonia. After this conversion, the plants absorb this substance. It can pass to animals when they eat these plants. Then, when they urinate, bacteria convert ammonia to nitrogen again and it returns to the atmosphere.

goldenfox [79]

Answer:

46 chromosomes

92 Chromatids

One DNA molecule

Explanation:

The interphase part of the cell cycle is divided into 3 sub-phases namely; G1 phase, S-phase and G2-phase

G2-Phase occurs when the cell grows more to make more proteins and organelles. This also when the cell reorganize its contents in preparation for mitosis.  The number of chromosomes will therefore, remain the same but the DNA molecule will be one in preparation for mitosis where it can then divide into two
