Susan made observations about outside events she noticed throughout the day. The day began with rain. Susan saw puddles on the r
S_A_V [24]

Answer:

Rainfall - precipitation

disappeared puddles - evaporation

cloud formation - condensation

Explanation:

Rainfall that is observed by the Susan is the precipitation of the water cycle in which the water vapor that was condensed become heavy and form droplets of water and fall from sky to the earth surface.

Puddles that formed due to rainfall are the collection of water in the water cycle which is evaporated (process: evaporation) into the atmosphere n the form of water vapor which condensed to form clouds.

astra-53 [7]

The diagram below shows the different aspects of the water cycle, such as how water is observed by plants and how it is carried around by the atmosphere.

The diagram relates to a cactus biome.

Cactuses are still plants,

We have several characteristics that make cactus a plant:

1. Photosynthesis

Unlike other plants that photosynthesize with their leaves, cacti do so with their stems. At night, they take in carbon dioxide, which is then used during the day.  

2. The stem succulent

A cactus is classified as a succulent. In other terms, a succulent is a plant that has thick juicy stems or leaves that store water. A cactus stores its water in stems, and some species are adapted to arid areas.  

3. Special skin surface

One attribute that makes cacti not lose a lot of water is the fact that they have waxy surfaces that prevent evaporation. Some species also have ribbed surfaces that prevent splitting even when the plant expands during desert rainstorms.

4. Cactus spines

Cacti have spines that protect them from being eaten by animals. The spines also act as insulation during the dry seasons.

How do cactuses survive in the desert?

A cactus is able to survive in the desert due to the following features:

It has long roots that go deep inside the soil for absorbing water.

Its leaves are in the form of spines to prevent water loss through transpiration.

Its stem is covered with a thick waxy layer to retain water.

This shows how cactuses can survive without water and this relates to what the diagram shows however, the diagram shows that rain takes a part in the water cycle, whereas for cactuses, they don't need much water due to their extreme adaptivity.

But there are some similarities too, for example cactuses are still plants so they still photosynthesise and give us oxygen and whatnot.

Forgive me if this is wrong, I tried my best <3 Have a great day

(Forgive me if this is too long just use the important part)

What is the formula for CO3 2- and Al3+ ?
Goryan [66]

Answer is: formula is Al₂(CO₃)₃.

Aluminium carbonate (Al₂(CO₃)₃) has neutral charge. Because aluminium cation has positive charge 3+ and carbonate anion has negative charge 2-, for right chemical formula, we need two aluminium cations and three carbonate anion:

charge of the molecule = 2 · (3+) + 3 · (-2).

charge of the molecule = 0.
