Answer:
Anomalous expansion
Explanation:
Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.
At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.
When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.
This way, organisms can survive in the water due to the lower layer not freezing.
D. Darwin's theory of natural selection shows that organisms evolve based on which one's survive the best and thrive.
The base sequence in the DNA is A=T
G=C
Answer:
Sugars move from “source” to “sink” ... Sugars produced in sources, such as leaves, need to be delivered to growing parts of the plant via the phloem in a process called translocation, or movement of sugar. The points of sugar delivery, such as roots, young shoots, and developing seeds, are called sinks.
Explanation:
u will get 10 out of 6
When a molecule is made up of one sugar unit, its called a monomer.
Eg. Glucose, galactose, fructose
When a molecule is made of more than one sugar units, its called a polymer.
Eg. Cellulose, glycogen
Polymers are usually macro molecules.
