Can you determine the relationship between the risk of contracting Lyme disease and the concentration of ticks that act as vecto

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.

How can the presence of one species benefit another in the same ecosystem
tekilochka [14]

Answer:

The different species present in an ecosystem make the ecosystem balanced.  The species of an ecosystem interact with one another in one form or the other. For example, the presence of a plant species will provide food for the abundant types of herbivores present in an ecosystem. A predator might feed on many types of preys. Hence, the presence of different preys will reduce the chances of a species from becoming wiped out from the ecosystem. Hence, all the organisms in an ecosystem are dependent on another in some way or the other.

True or false? cell death normally does not occur unless there has been an injury to the cell.
Evgen [1.6K]

The statement 'cell death normally does not occur unless there has been an injury to the cell' is false.

A cell can be described as the basic building block of life. All living organisms are known to be made of cells.

There are various reasons that a cell might die. A cell might die when its function is over. A cell might also die for the formation of other structures in the body. For example, the formation of an outer layer of the skin requires dead cells. A cell might kill itself if it has no use or finds that it has been invaded by an antigen.

Hence, the statement that cell death occurs only due to injury is false as cell death can occur due to various other reasons.

Match the term on the left with its definition on the right.
noname [10]

Answer:

1. Eutrophication  - When fertilizers, animal waste, or sewage flow into waterways, causing algal blooms  and depriving other organisms of oxygen .

2. Biological  augmentation  - Adding natural predators to a damaged ecosystem .

3. Ecological  footprint  - The number of natural resources used to support an individual's lifestyle .

4. Biodiversity  hotspot  - Areas of high biodiversity that have been significantly impacted by human activities .

5. Acid  precipitation​ - The result of pollutants reacting with water in the air to form sulfuric acid, which falls  back to the earth's surface in rain, snow, sleet, or fog .

Explanation:

  • Eutrophication

The enrichment of an aquatic ecosystem by minerals and nutrients caused by animal waste, human activities like sewage flow, farming, etc that lead to fertilizer runoff into waterways causing algal blooms which results in the oxygen depletion of the aquatic ecosystem. Algal blooms block sunlight from getting into the water and deprives other organisms of oxygen, thus harming the plants and animals in the ecosystem. Some species of algae produce toxins that are harmful to human or marine life.

  • Biological augmentation

It is the most efficient way to clean and restore nature and natural resources like water bodies, soil, etc by decomposing pollutants and adding essential materials to a damaged or degraded ecosystem with the use of organisms such as bacteria. Examples include increasing the available nitrogen in soil by nitrogen-fixing plants, wastewater treatment, cleaning of ponds and lakes by adding bacterial cultures, enzymes, etc.

  • Ecological footprint

It measures the number of natural resources and how fast they are consumed to support people or an economy and also the waste generated, i.e., measurement of human demand on nature. For the calculation of ecological footprint, the usage of certain categories of productive surface areas such as forest area, cropland, fishing grounds, grazing land, built-up land, carbon demand on land, etc is tracked. Based on this information, the quantity of natural resources we have and how much of these resources are used is measured.

  • Biodiversity hotspot

It is a biologically fertile region that has a rich distribution of plants and animal species not found anywhere else and is highly threatened with destruction by human habitation. Examples of biodiversity include the Andes Mountains tropical hotspots, New Zealand archipelago, forest habitats, etc.

  • Acid precipitation​

It is any form of precipitation including rain, dust, fog, snow or hail with acidic components that possess a pH of about 5.2 or below, such as nitric or sulfuric acid that fall to the ground from the atmosphere. The fossil fuel emissions such as sulfur dioxide, nitrogen oxide, etc react with the water molecules in the atmosphere to produce acid precipitation. By reducing fossil fuel emissions, the effect of acid precipitation can be reduced.
