Answer;

both positive and negative

Explanation;

-The elephant are keystone species, playing an important role in maintaining the biodiversity of the ecosystems in which they live. They may have both negative and positive interactions to the environment. For example, during the dry season, elephants use their tusks to dig for water, which has a positive impact to the surrounding.

A ship is at anchor. Over its side hangs a rope ladder with rungs a foot apart. The
Triss [41]

Answer:

At the end of 6 hours, 6 feet of the ladder remained above water

Explanation:

we are given the following:

change in tide = 8 inches per hour

1 hour = 8 inches

∴ 6 hours = 8 × 6 = 48 inches

Now, since the length of the ladder is measured in foot, let us convert the rate of tide rising to foot.

12 inches = 1 foot

dividing both sides by 12:

1\ inch=\frac{1}{12}\ feet\\ \therefore 48\ inches\ =\ 48\ \times \frac{1}{12}\\ =\frac{48}{12}\\ = 2 feet

Therefore, after 6 hours, the tide rises by 2 feet.

Next, we are told that the rope ladder at the beginning was 8 feet, hence the length remaining above water after 6 hours of the rising of the tide is calculated as follows:

= 8 feet above water

height of tide = 2 feet = amount submerged in water

∴ length above water = (ladder before rising of the tide) - (amount submerged in water)

length above water = 8 - 2 = 6 feet

Therefore at the end of 6 hours, 6 feet of the ladder remained above water
