Luda [366]

Answer:

This question lacks options, options are: a. Keystone species b. Dominant species c. Competitor species d. Omnivore species e. Mutualistic species. The correct answer is a.

Explanation:

The most connected species from a trophic point of view in an ecosystem are keystone species, since their elimination has great effects on the stability and persistence of the network. The Keystone species are those species that play a crucial role in the structure and dynamics of a certain ecosystem and that, in the event of their disappearance, would be seriously unbalanced. These species are responsible for the physical structure of the habitats of many other species, and they play an important role in the succession processes of ecosystems. Elephants play an important role in maintaining the structure and balance of ecosystems in these communities, therefore they are keystone species.

alex41 [277]

Answer:

The correct answer is option c.

Explanation:

The ABI or the ankle-brachial index examination refers to a noninvasive and brisk way to determine PAD or peripheral artery disease. The disease takes place when narrowed arteries diminish the flow of blood to the limbs. The condition can result in leg pain at the time of walking and enhances the chances of stroke and heart attack.  

On the basis of ABI, one can find that a healthy individual lacking arterial insufficiency exhibits an ABI of about 10. Those with an ABI of 0.95 to 0.5 shows minor to modest arterial insufficiency. The individuals with an ABI of less than 0.50 exhibits ischemic rest pain. Those with the loss of tissue show extreme ischemia and an ABI of 0.25 or less.
