Answer: True
Humans have impacted the rainforests through mining, agriculture and construction as rainforests are mainly occupied with large forests trees and vegetation. Human clear cut the forests to make the land available for the purpose of mining to derive economically valuable minerals from earth, construction of house and for agriculture. This has resulted in the extinction of large number of floral and faunal species from earth. It has decreased the percentage of forest cover on earth.
According to the question, it is true that Humans have impacted the rainforests through mining, agriculture, and construction.
How human impacted the rainforests through mining
Gemstones and Precious metals such as gold, copper, diamond are important resources that can be found in the rainforests across the world. Extracting these resources is harmful activities that contribute lot of damages to the rainforests ecosystem. It causes problem for the people that live close to the rainforests. Chemical pollution and deforestation from mining can have a great adverse effect on the rainforests environment. It also affects downstream aquatic habit.
How human impacted the rainforests through Agriculture
In the rainforests, large areas are cleared for pastoral farming because the demand of meat globally has increased the opening of cattle farms in the rainforests and this also cause deforestation which has adverse effect on the rainforests. Arable farming also contribute to the loss of tropical rainforests as many farmers are clearing the land to grow crops such as soya beans.
How human impacted the rainforests through Constructions
Road building has different of direct impacts on the rainforests. In most wet tropical rainforest, the cut and fill operation related with road construction can prevent easy flow of streams, increase flooding in the forest and can drastically increases erosion in rainforests. Construction of roads in the rainforest can discharge nutrients and chemical pollutant into water ways and create avenue of invasion for disturbing exotic species.

Answer:
The water cycle is driven by the sun's energy. Water constantly changes state between solid, liquid and gaseous, this is due to solar energy and the force of gravity
Explanation:
Thanks to the effect of the energy of the Sun, water from the oceans and rivers, lakes, swamps, etc. It heats up and then evaporates. The sun is the one that governs the water cycle. The currents that rise in air transfer steam to the atmosphere, where it is at a lower temperature that causes the steam to condense and clouds form.
How did detectives nab the suspect based on the pod evidence?
A) Detectives knew that Palo Verde trees grew in a limited area of the state.
B) Detectives used DNA markers to match the pods from the truck to pods on the scene.
C) Detectives constructed a pedigree chart of the trees in the area to determine genotypes.
D) Detectives did test crosses in the lab to determine the relationship of the pods and trees
Detectives used DNA markers to match the pods from the truck to pods on the scene to nab the suspect in an ongoing murder investigation. Hence, the correct option is B.
DNA markers are the variations that can be used to identify and track specific genes or regions of the genome. DNA markers are used in a variety of applications including medical, genetics, forensic science and agriculture.
There are several types of DNA markers such as SNP, AFLP, microsatellites, RFLP. In forensic science, they are used to identifying individuals by analyzing the DNA samples that are collected from the scene of crime.
In the case given here, by using DNA markers, the forensic experts helped the detectives to match the pods from the truck to the pods on the scene. Hence, the correct option is B.
