Which of these kingdoms is the most diverse?
a. fungi
b. protists
c. animals
d. plants

c. animals

Explanation:

The animal kingdom is the most diverse of all and has over 1 million species described, not to mention those still unknown to man. The Animalia Kingdom has over one million species arranged in over 30 phyla. One of the kingdom's most striking features is its ability to move, although there are also sessile (non-moving) representatives. In addition, animals have cells that form tissues, except for porifers, which do not have true tissues.

The animal kingdom is usually divided into two major groups: vertebrates and invertebrates. This first group, despite being the best known, represents only 5% of all existing animal species. Invertebrates, in turn, group the largest number of species, with about 95%. It is worth noting that this classification is artificial, being used only for didactic purposes.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
