Which of these species would be most in danger of becoming extinct if one of their food sources became unavailable?
Advocard [28]

Answer:

Due to their being no options (possibly just an incomplete question), I will just give an answer. So for panda bears, if their food sources became unavailable, they would most likely be in danger of becoming extinct.

But one thing is, pandas do have the ability to survive with bamboo.

But since bamboo comprises 99 percent of their food, although they also consume other plants and even meat, I highly doubt they could (whose make the remaining 1 percent ).

Because the gene T1R1 mutated some 4 million years ago, causing them to lose the ability to taste umami, giant pandas have come to rely significantly on bamboo (which is what makes meat tasty for omnivores and carnivores). The availability of bamboo trunks at the time coincided with their purported food source becoming increasingly limited, thus pandas became used to them and began to rely significantly on them, as they do now.

Thank you,

Eddie

A facility would like to verify each individual's identity prior to allowing access to its server room and datacenter. Additiona
yKpoI14uk [10]

Answer:

C. Implement a biometric reader at the datacenter entrance and require passage through a mantrap.

Explanation:

The first step this installation should do is to limit access to only authorized persons. The safest way to do this is to use a biometric reader at the datacenter entrance, so in addition to just entering authorized persons, it would be possible to verify each individual's identity before allowing access to the server room and datacenter. The facility should also use a mantrap to separate safe areas from unsafe areas, so it can also limit access to the facility and decrease the chances of users tailgate behind other uses.

How do pioneer species make ecological succession possible on an island formed from a volcanic eruptions
SIZIF [17.4K]

Answer:

The correct option is <em>3. they break down rock into soil in which plants can grow</em>

Explanation:

When a disaster is such huge that even the soil and organic matter get removed from the place, then the succession that will occur in such kind of place will be termed as primary succession. For example, a volcanic eruption or an earthquake.

On the other hand, if after a disaster some of the organic matter remains on the land, then the succession that will occur will be termed as secondary succession. E.g a succession after fire

In primary succession, the pioneer species will be plants that require less soil such as the lichens. The lichens will break down the rocks into the soil and eventually new species of plants will start to grow on the land.
