In drinking water, the more turbid it appears, the higher the chance that  those using it could end up with  gastrointestinal diseases.  The water may be having contaminants such as viruses and pathogenic bacteria which are found attached to suspended solids. These solids may interfere with disinfection of the water.
Erosion and effluent from highly urbanized  areas contribute to the turbidity of water in those areas.  In open bodies of water, organisms such as phytoplankton can contribute to turbidity in the water. 
 
        
             
        
        
        
Answer:
Dissimilar organisms might have evolved from a distant, common ancestor.
Explanation:
First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism. 
Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.
 
        
             
        
        
        
Answer:
lysosomes, small molecules 
Explanation:
-plants:usually not evident Animals: occurs in cytoplasm
-small organelles filled with enzymes 
-"clean up crew" 
- the digestion or breakdown of lipids, carbs, and small proteins into small molecules that can be used by the rest of the cell 
-involved in breaking down organelles that have outliveed their usefullness 
-diseases are trace to lysosomes that dont function properly
 
        
             
        
        
        
Q1. The answer is 1.
It can be calculated using the equation:
 (1/2)ⁿ = x
x - decimal amount remaining, 
n - a number of half-lives.
x = 50% = 50/100 = 0.5
n = ?
(1/2)ⁿ = 0.5
log((1/2)ⁿ) = log(0.5)
n * log(1/2) = log(0.5)
n * log(0.5) = log(0.5)
n = log(0.5)/log(0.5)
n = 1
Q10. The answer is 2.
It can be calculated using the equation:
 (1/2)ⁿ = x
x - decimal amount remaining, 
n - a number of half-lives.
Rhyolite #2 has 25% of the parent H remaining:
x = 25% = 25/100 = 0.25
n = ?
(1/2)ⁿ = 0.25
log((1/2)ⁿ) = log(0.25)
n * log(1/2) = log(0.25)
n * log(0.5) = log(0.25)
n = log(0.25)/log(0.5)
n = -0.602 / - 0.301
n = 2
Q3. The answer is 100 million years.
A number of half-lives (n) is a quotient of total time elapsed (t) and length of half-life (H):
n = t/H
n = 1
t = ?
H = 100 000 000 years
n = t/H
t = n * H
t = 1 * 100 000 000 years
t = 100 000 000 years<span>
