Answer:
a. bottleneck effect.
Explanation:
A bottleneck effect occurs when some adverse environmental conditions such as typhoons and famine reduce the population size considerably. The allele frequencies of the population are changed. As the population grows again, the gene pool has different allele frequencies than the original population. During population growth, some harmful alleles may become more abundant resulting in a rare disease such as achromatopsia. Therefore, the given population represents the bottleneck effect.
They occur years apart, and the glacier theories is from research and just a theory..but the bible account of the flood is more a story instead of research and science.
Answer:
a. Tibia
b. Fibula
c. Talus
Explanation:
The ankle joint consists of three bones: the fibula, the tibia and the talus. The first two make up a vault in which the dome of the third fits. It allows, above all, forward and backward turning movements, which are flexion and extension movements of the foot. In the lateral sense, the tops of the peroneal maleolus and tibial maleolus, which are the two bony appendages that continue fibula and tibia on both sides and downward, prevent a complete movement of lateral rotation although they do allow their onset.
The talus rests on the calcaneus (the bone that forms the heel) forming a fairly flat joint, without great movement. This subastragaline joint is a source of conflict as it supports the transmission of body weight forces and governs fine movements of foot stability. When the cartilage of this joint deteriorates, an arthritic degeneration and pain occurs, which sometimes forces surgical intervention to suppress or relieve it.
