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.

Many bedbugs are highly resistant to insecticides, but the scientist’s bedbugs aren’t resistant. Explain why this happens based
Nutka1998 [239]

Wild Bedbugs become insecticide resistant because of the mutations and natural selections.

<h3><u>Explanation</u>:</h3>

As the huge amount of pesticides and insecticides are sprayed in the rooms for cleaning, the pests and insects like bedbugs dies in huge portions because of the toxin. But some of the bedbugs remain alive as they have mutations that help them to detoxify the toxins given, or bypass the metabolic processes so that the toxins don't hamper them much.

Now as the population becomes very small(bottle neck effect), the nature selects these organisms over the other to propagate more sufficiently and enormously. As the nutrients and supplies are also available, so the bedbugs don't suffer any lack of nutrition which can be a determining factor of their population.

Thus the wild bedbugs become resistant to insecticides while the experimental one remain succeptible to insecticides.

They are all rock with different size and shapes and are located in different areas possibly in the same areas but they all have there own unique textures from the photographs and 3 of them look like maybe a fossil of some type of when the dinosaurs where still around and the rocks on the top left corner look smooth and are a small type of igneous rocks. That have been soothed over the years.
