Answer: Since the vector transmitting the disease is the tick, the higher the density of ticks, the higher the rate of transmission of the disease.

Explanation:

Lyme disease is an infection caused by a spirochete-like bacterium of the Borrelia species and is transmitted by a vector, which is a living being (almost always an arthropod) capable of transmitting a disease to vertebrate hosts, including humans.

In this case, the disease is transmitted to humans through the bites of deer <u>ticks that are infected with this bacterium</u>. The ticks live in forests or grassland areas, woodlands and swamps near rivers, lakes or seas. Infections generally occur from late spring to early fall because infected deer ticks live in regions that have extreme temperatures (very low and very high) and high levels of humidity.  

The first and most obvious symptom of Lyme disease is a localized rash that begins as a pink or red circle that expands over time and may appear 3 to 30 days after the bite. Although the disease can also affect the skin, nervous system, joints, muscles and heart.

Therefore, since the vector transmitting the disease is the tick (without ticks there is no transmission), the higher the density of ticks, the higher the rate of transmission of the disease.

Describe the effect on animal cells of the cells do not contain enough water
lesya [120]

Answer:

Animal cells also take in and lose water by osmosis. They do not have a cell wall, so will change size and shape when put into solutions that are at a different concentration to the cell contents. Red blood cells lose water and shrink in a concentrated solution. They swell and burst in a solution that is too dilute.

In nutrient-rich environments (like your mouth), bacteria can use the provided amino acids to synthesize their proteins. However
kirill115 [55]

Answer:

The correct answer will be option-A  

Explanation:

The citric acid cycle is the cyclic chain of reactions taking place as a phase of the cellular respiration as it gets halted in the absence of oxygen. The citric acid cycle converts the obtained acetyl-CoA to a usable form of energy in the form of ATP, NADH and FADH₂.

The citric acid cycle forms intermediates which are utilised by the organisms to synthesise the various biomolecules like amino acids, purines and pyrimidines.

The intermediates like alpha-ketoglutarate forms arginine, proline and glutamine whereas oxaloacetate forms asparagine and aspartate. If bacteria do not receive the amino acids then they will synthesise the amino acids using intermediates of the citric acid cycle.

Thus, option-A is the correct answer.
