The question was; which of the following examples posses the greatest potential threat to biodiversity?
The answer would be; A, constructing oil gas pipelines through old growth forest.
Biodiversity refers to the variability and variety among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part. Human activities poss great threat to biodiversity, these include defforestation, and others like construction which involves destruction of trees and other habitats for living thing.
The most common types of cancer occur in AIDS patients are Kaposi's Sarcoma, non-Hodgkin's lymphoma, and cervical cancer (in women). AIDS patients are immunocompromised so that their immune system is weak. Therefore, the most common type of cancer in AIDS patients is liver cancer.

Answer:
Explanation:
This is the process of muscle contraction and relaxation in the muscle. The type of muscle involved is the skeleton muscle.
The process is initiated in the Central nervous system. Examples are in contraction of biceps and triceps.
It involves myosin head and actin filament coupled with the release of calcium ion from the sarcoplasm reticulum: this ion activates this process in the muscles. With the exposure of the music binding site on the acting filament, myosin is able to bind to acting filament bringing about this process.
a. ATP attaches to myosin head
b. Myosin head is re-energized
c. Myosin head forms cross bridge with actin
d. Power stroke moves thin filament
e. Cross bridges detach from actin
f. Myosin binding sites covered
g. Calcium ions pumped into the sarcoplasmic reticulum
h. Calcium ion concentration decreases below the threshold for binding to troponin.
