Answer;

B. Periodic drought causes an abrupt decrease in vegetation.

Explanation;

-Density-independent factors are those factors limiting the size of a population whose effect is not dependent on the number of individuals in the population, such as weather and climate, exert their influences on population size regardless of the population's density.

-The density dependent factors on the other hand are factors whose effects on the size or growth of the population vary with the population density. There are many types of density dependent limiting factors such as; availability of food, predation, disease, and migration.

Why dont earth quakes count as severe weather
Sonbull [250]

This theory led to a belief in 'earthquake weather', that because a large amount of air was trapped underground, the weather would be hot and calm before an earthquake. A later theory stated that earthquakes occurred in calm, cloudy conditions, and were usually preceded by strong winds, fireballs, and meteors.

telo118 [61]
<span>
1. Although the state of Florida receives a lot of rainfall, about 61 percent of that water leaves the ground by evaporation and transpiration, and another 38 percent is ‘lost’ into the Atlantic Ocean & Gulf of Mexico, thus leaving only 1 percent of the rainfall water available for drinking and other human use. 

 2. Florida has a very vast underground water system, known as the Floridan aquifer system; for this reason, Florida is the source of drinking water to four other states. These states are South Carolina, Georgia, Alabama, and Mississippi. The Floridan underground water system is made up of the Upper and Lower Floridan aquifers.

3. Residents of the state of Florida wanted to get rid of the water in certain areas of the state because there was too many wetlands, they experienced frequent flooding which posed a great measure of difficulty in navigating the state.

4. One negative result of the changes made by people in order to get rid of the ‘excess’ water in Florida was groundwater depletion which has led to the drying up of wells, decrease in water level in streams and lakes, reducing quality of water and land subsidence.

5. One thing that has been done to try and improve those mistakes is Rainwater harvesting; a method which is often used to replenish ground water. Using the rainwater harvesting approach, an outlet pipe is connected from the rooftop and used to divert the rainwater to existing wells.

What makes arteries unique ?
ehidna [41]

Arteries are blood carrying vessels which have thick, elastic,  muscular walls, have no valves and in which blood flows under high pressure. The make up of arteries is unique to their function of transporting blood under high pressure. 

All arteries carry oxygenated blood from the  heart to all other parts of the body, with the exception of the pulmonary artery which carries de-oxygenated blood from the heart to the lungs. It is the only artery that transports blood which has not been oxygenated.

goblinko [34]

Answer:

Diagram, in attachments

Explanation:

From the left side of the screen to the right,that is from a structure with a sugar structure with two other molecules  attached to it.

The first molecular structure is Nucleotides. Reasons it contains the middle ribose sugar(5-carbon)connected to the phosphate group and  Nitrogenous bases.This is the structure of nucleotides  and when this is joined by phosphodiester bond between one a nucleotide, to the phosphate group of another  nucleotide molecule  it forms a nucleic acid molecule.

The second structure from left to right with  long carbon chains, it is  a lipid.That js an Ester formed from the reaction of fatty acids with alcohol glycerol.

However, the presence of Phophate group in structure makes it different from a normal tryglycerides.The phosphate group has replaced  one of the  the three fatty acid molecules.Therefore it is called Phospholipid.With one hydropholic ends(phosphate ends) and the hyrophobic end the  carbon chain,with one unsaturated. The lipids molecules are held together my ester bonds.

The next structure is the protein structure(dipeptide).Genrally amino acid is made up of the central Alpha carbon connected on the right by the Carbonyl group(coo-) on the left by the Amine(NH2) group.The R-group which determines the type of amino acids  and hyrdogen atom.In the above structure condensation reaction  has occurred between the hydrogen atom  of  the amine group and carbonyl group of the other amino unit to form a dipeptide.The  bond formed from the condensation is the peptide bond.

The last structure on the far right are the carbohydrate -ring structure and the straight chains.The functional groups of the CHO  -Carbonyl group and hydroxyl group are glues to this.
