We see rainbows when the son is behind us and some type of water or rain is in front of us. When the sun light hits a raindrop it's refracted and is changed in direction.
(and we see them with our eyes mannnn or womannnn)
<h2>Blood stain patterns.</h2>
Explanation:
- <u>A pool of blood</u><u> </u>occur(s) when blood collects in a level (not sloped) and undisturbed place, while<u> </u><u>voids</u> occur(s) when an object blocks the deposition of blood spatter onto a target surface or object and the spatter is deposited onto the object or person instead.
Analysis of blood stain patterns are significant step in crime investigations. They often give the idea of the type of weapon used , the manner of crime and the time of crime.
When blood drops on a flat surface, it does not flow but dries there. The drying time of blood is possible to be calculated. The drying time of the blood can give an idea about when the events associated with crime occurred.
Since voids are created when any object blocks the blood from spattering on the target object, an impression of the blocking object is formed. it is often the body of the victim or the weapon of crime. So an idea about victims position and shape of weapon can be assumed by void analysis.
Butterflies are among the most vibrant insects, with colorations sometimes designed to deflect predators. New research shows some of these defenses may be driven by enemies one-tenth their size.
Competition is the answer
Answer: a. precipitation (rain), person, wastewater, clouds, precipitation(rain).
Water cycle also known as hydrological cycle describes how water evaporates from the water body or surface of the earth, rises in the atmosphere as water vapor which forms clouds, clouds condenses in the form of rain, hence water comes back in the water body or earth surface.
Here, precipitation will result in accumulation of water on earth or water body, this water is utilized by person, the water is then converted into wastewater, the cloud formation takes place when water evaporates from waste water, these clouds condenses to cause precipitation.
