Annette [7]

Answer:

1. Lupus

2. Cardiovascular disease

3. Huntington disease

4. Cancer

5. Diabetes

Explanation:

A disease can be defined as any harmful or abnormal deviation of the body of a living organism from its functional state or normal structure, which is typically accompanied by certain signs and symptoms.

Basically, a disease negatively affects the function or structure of the body of a living organism.

The different types of diseases experienced by living organisms include the following;

1. Lupus: occurs when the immune system attacks the body. It is referred to as an autoimmune disease.

2. Cardiovascular disease: is often caused by obesity resulting from overeating and poor nutrition.

3. Huntington disease: is caused by DNA changes in a single gene and affects the nerve cells in the brain.

4. Cancer: is caused by uncontrolled cell growth.

5. Diabetes: occurs when the pancreas does not produce enough insulin, or the body does not respond properly to it.

How does the removal of top predators affect mesopredator populations?
Aleksandr [31]
The removal of top predators affect mesopredator populations in that the geographical range and abundance of the mesopredators will increase. Top predators are the predators that eat herbivores and the mesopredators, therefore their removal would mean the mesopredators and the herbivores will not be predated and thus their population will increase.

What are convergent boundaries?
boyakko [2]

Answer:

Explanation:

A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.[1] These collisions happen on scales of millions to tens of millions of years and can lead to volcanism, earthquakes, orogenesis, destruction of lithosphere, and deformation. Convergent boundaries occur between oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere. The geologic features related to convergent boundaries vary depending on crust types.

Plate tectonics is driven by convection cells in the mantle. Convection cells are the result of heat generated by radioactive decay of elements in the mantle escaping to the surface and the return of cool materials from the surface to the mantle.[2] These convection cells bring hot mantle material to the surface along spreading centers creating new crust. As this new crust is pushed away from the spreading center by the formation of newer crust, it cools, thins, and becomes denser. Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle.[3] As the relatively cool subducting slab sinks deeper into the mantle, it is heated, causing hydrous minerals to break down. This releases water into the hotter asthenosphere, which leads to partial melting of asthenosphere and volcanism. Both dehydration and partial melting occurs along the 1,000 °C (1,830 °F) isotherm, generally at depths of 65 to 130 km (40 to 81 mi).[4][5]

Some lithospheric plates consist of both continental and oceanic lithosphere. In some instances, initial convergence with another plate will destroy oceanic lithosphere, leading to convergence of two continental plates. Neither continental plate will subduct. It is likely that the plate may break along the boundary of continental and oceanic crust. Seismic tomography reveals pieces of lithosphere that have broken off during convergence
