Igneous rocks are formed when the magma from an erupting volcano eventually cools this rock is extrusive- found on the earth's surface.
Answer:
Explanation:
you could do Water's Attraction to Other Polar Molecules.
Cohesion, otherwise known as water's attraction to other water molecules, is one of the big properties of water. Water's polarity lends it to be attracted to other water molecules. The hydrogen bonds in water hold other water molecules together. Due to water's cohesiveness:
Liquid water has surface tension. This allows for insects, such as Water Striders, to walk on water.
Water is a liquid at moderate temperatures, and not a gas.
Using an eye dropper and a coin, you can slowly keep adding water to the coin and you will see cohesion.
The water molecules will stick together and form a dome over the coin. Keep adding drops until the drop breaks and spills off of the coin. This is caused by gravity overcoming the force of cohesion.
Answer:
Any factor in the environment that does not depend on the number of members in a population.
Explanation:
Density independent limiting factors also cause population sizes to increase. For example, the water from a flash flood increases the growth of vegetation, thereby providing more food for primary consumers in the ecosystem.
Answer:
The functional groups that define the two different ends of a single strand of nucleic acids are:
B. a free hydroxyl group on the 5' carbon a free hydroxyl group on the 3' carbon
G. a free phosphate group on the 5' carbon
Explanation:
A nucleic acid is a polymer formed of nucleotides that are linked with a phosphodiester bond. The structure of a nucleotide consists on a phosphate group linked to a pentose (ribose in RNA and deoxyribose in DNA) that is also attached to a nitrogenous base. The nitrogenous bases are adenine, guanine, cytosine, thymine (in DNA) and uracil (in RNA).
DNA and RNA are nucleic acids which can be found in a double or single strand presentation.
Nucleic acids are synthesize in the 5’ to 3’ direction, so that is why the convention is that the sequences are written and read in that direction.
The strand of a nucleic acid is directional with an end-to-end orientation, where the 5’ end has a free hydroxyl or phosphate group on the 5' carbon of the terminal pentose, and the 3’ end has a free hydroxyl group on the 3’ carbon on the terminal pentose (ribose/ deoxyribose).
