Answer:
Water vapor is a greenhouse gas, which absorbs the heat radiated from the earth's surface. It allows less heat to escape back to space by trapping the heat energy in the lower atmosphere and keeps the atmosphere warm.
Explanation:
Water vapor is formed through a process called evaporation. In this process, water from the ocean, rivers, and lakes evaporates to become water vapor using the energy from the sun. Water vapor also moves into the atmosphere by transpiration (plants) and sublimation (snow and ice).
The water vapor cools down and transforms into water droplets by a process called condensation, as it rises high in the atmosphere where the air is cooler. This water droplets that formed by condensation make up clouds.
When the earth’s surface get heated by the sunlight, some of the heat radiates back into the atmosphere and most of this heat is absorbed by gases in the atmosphere called green house gases. This process is called greenhouse effect, which keeps the earth warm. The green house gases mainly consists of carbon dioxide and water vapor. Water vapor absorbs the heat radiated from the earth's surface. It allows less heat to escape back to space by trapping the heat energy in the lower atmosphere and keeps the atmosphere warm.
The amount of water vapor in the atmosphere is directly proportional to the temperature. When addition of the other greenhouse gases causes a temperature increase (such as extra CO2 from fossil fuels), more water evaporates and this leads to an increase in water vapor which further increases the atmospheric temperature since water vapor is a greenhouse gas. So, water vapor is part of a positive feedback system.
The correct answer is option a, that is, multicellular, heterotrophic, and diploid.
Animals refer to the multicellular eukaryotic species, which forms the biological kingdom Animalia. Animals exhibit many features, which distinguish them from other living species. The animals are multicellular and eukaryotic, unlike prokaryotic bacteria, and unlike protists that are eukaryotic but unicellular.
The animals are heterotrophic, not like algae and plants that generate their own food. Almost all the animals make use of some kind of sexual reproduction. They are diploid and generate haploid gametes by the process of meiosis, the larger non-motile gametes are ova and the smaller motile gametes are spermatozoa.
