Well to move they need help from the muscles, because by their own they are just like a bunch of sticks
The best option for this question is: '<span>It increases the amount of runoff</span>'. Plant life acts as a barrier to the overland flow of water, thereby slowing the flow and allowing increased infiltration of water into the soil. Deforestation and overgrazing are major contributors to erosion, as plants act to bind the soil, and their removal allows the combination of looser soil and increased runoff to move masses of sediment into rivers and lakes. Deforestation will in fact decrease transpiration and percolation and precipitation rather than increase them.
Answer:
300 meters/min
Explanation:
average speed = distance / time
(3000 m) / (10 min) = 300 meter per minute
if you need it in meters/sec then just multiply 10 by 60 first and then continue
(3000 m) / (600 sec) = 5 m/s
It should be a molecule not an atom.
The molecule is potassium carbonate
Answer: The correct answer is-
B) guanine.
DNA ( deoxyribonucleic acid) is considered as the genetic material of living organisms. It is made up of small units called nucleotides. A nucleotide is hat is composed of -
1)nitrogenous base, which can be Adenine, Thymine, Guanine, Cytosine
2) Phosphate group, 3) Deoxyribose sugar.
In a DNA molecule, Adenine pairs with Thymine, and Guanine pairs with Cytosine as per the Watson and Crick base pairing.
If the green nitrogen base in the DNA model represents adenine, this indicates that thymine will also be green ( as it pairs with adenine).
Thus, the blue nitrogenous base will be represented by Guanine.
