Answer:
The hill models gravity as a driving force in the water cycle.
Explanation:
Gravity (the gravitational force that pulls objects towards the centre of the Earth) drives the water cycle.
Gravity is responsible for precipitation (rain, hail, sleet, and snow) falling downwards towards the Earth's surface. It is also responsible for water at higher points on the Earth's surface flowing downwards to the lower points on the Earth's surface.
In Carlos' model, the hill represents a higher point on the Earth's surface while the valley represents a lower point on the Earth's surface. The river, flowing downwards from Carlos' hill to Carlos' valley, demonstrates the role of gravity as the driving force of the water cycle.
Answer:
a) the selection intensity is 21bushels/acre
b) the response to selection is 12bushels/acre
c) The heritability is 0.57 (two decimal places)
Explanation:
Given:
mean grain yield population=72bushels/acre
mean grain yield selected individuals=93bushels/acre
mean grain yield new population=84busgels/acre
a) The selection intensity is given by:
SI=mean grain yield selected individuals-mean grain yield population=93-72=21bushels/acre
b) The response to selection is:
RS=mean grain yield new population-mean grain yield population=84-72=12bushles/acre
c) The heritability of grain yield is:
H=RS/SI=12/21=0.57
Competition is one of the many types relationships in the ecosystem. It is an oppositional relationship because unlike in symbiotic relationships, the organisms do not peacefully coexist. Using the given information above, we can deduce that the two fungi compete with one another in terms of the resources plus the habitat.
The answer would be deep roots to absorb ground water.
Cacti are found in deserts, which do not receive much rain. Cacti, like all plants, need water to live so deep roots would help the cactus obtain water.
Hope this helps!
The water cycle can be described as the cycle of different processes by which the water circulates between the ocean, atmosphere, and the land. It includes, precipitation (rain and snow), drainage, transpiration, and evaporation. The animals also play a crucial role in these cycle of processes. They release the water vapors into the atmosphere when they exhale, hence, letting the water molecules to again enter the cycle.
Hence, the correct answer is 'Option D - They release water vapor when they exhale'.
