1. Evaporation - During this process, surface water turns into water vapor. This is done by the transfer of heat energy. Water absorbs this heat energy and turns into its gaseous state.
2. Condensation - Water vapor rises into the atmosphere and is changed into water droplets. When gas is chilled, it turns back into a solid state. These water particles that form in the atmosphere then come together to form clouds.
3. Sublimation - Ice directly converts into water vapor without first converting into a liquid. This process accelerates when the temperature is low or pressure is high.
4. Precipitation - It is the result of evaporation and condensation. Precipitation describes any liquid or solid water that falls to Earth as a result of those two processes. It includes rain, hail, snow, sleet and a bunch more.
5. Transpiration - When precipitation happens, the soil absorbs some of the water. While in the soil, the roots of plants will take in the water and push it towards the leaves where it is used for photosynthesis.
6. Run Off - This happens as a result of precipitation, so it is again, technically not a process. As water pours down, it leads to runoff. This is the action of water running over the surface of the Earth. As water runs over the ground, it can displace the topsoil with it and move minerals along lakes, seas and oceans.
7. Infiltration -
This last process happens when water does none of the things stated above after precipitation. Sometimes, some of the water will move deep into the soil. Avoid the plants, avoid evaporation, avoid runoff, everything. The water instead seeps down and increased the level of the groundwater table. It is called pure water and is 100% fresh and drinkable.
Answer: sp+ zn+/ sp+ zn+ ; sp+ zn+/ sp zn; sp zn / sp zn
Explanation: f a double heterozygote is testcrossed and gametes are produced in a ratio of 1:1:1:1, this can be interpreted as unlinked genes or as genes that are 50 map units apart. Because gametes this far apart cannot be distinguished from gametes that are unlinked, it's not possible to get a ratio of gametes that indicates a distance of greater than 50 map units.
A man and a woman are trying to have children but are unsuccessful. As part of a series of tests, the man is karyotyped. His autosomes appear normal, but his sex chromosomes, shown in the following diagram, are not. The diagram also shows a normal male's sex chromosomes for reference.
