1. MOUNTAIN GOATS HAVE HARD HOOVES

Answer:
1. Mountain goats have cloven hooves with two toes that spread wide to improve balance. Rough pads on the bottom of each toe provide the grip of a natural climbing shoe. ... During the more moderate summer season goats shed this coat.
2. Whales and dolphins use their lungs to breathe air also. That's one reasons why they come to the surface of the ocean. ... Blow holes are surrounded by muscles that keep the hole closed when the whale or dolphin is under water and open it when the animal is at the surface and needs to breathe.
3. Lotus roots are found buried in anaerobic sediment and are characterised by having oval holes for obtaining oxygen.
4. The submerged leaves are often highly dissected or divided. This has the advantage of creating a very large surface area for absorption and photosynthesis. It also minimises water resistance and hence potential damage to the leaves.

Whales and Dolphins keep coming up to the water surface because they don't have Gills like other fishes which helps them to take the oxygen dissolved in water. dolphins do not have gill like other fishes . so they come up to the water surface to give out the carbon dioxide.
The Lotuses I closely observed were in various life stages; many were well-established (at Terra Flora and the Chicago Botanic Garden), and one was a young plant (in the water garden at my home). The plants were large overall, both in how much space they took and the size of leaves. They send the cylindrical stalks of both the leaves and flowers from the muddy bottom of the water high into the air.
The tuberous roots were not visible beneath the mud, but I could see the shoots emerging from the mud and out of the water. Each individual stem of leaf and flower rises separately from the root/muck (group consciousness?). The stems are hollow but extremely tough on the outside, with small, rather pointed “dots” along the entire length of the stem.
The leaves and flowers are borne high above the water’s surface, unlike those of the water lily, which float directly on the surface of the water. Initially, the leaves and flower buds are very pointy. The leaves are like tips of an arrowhead shooting up and unfurling into large, rounded, very broad cups. The cup-like leaves have a central “dot” which collects drops of water. This central, circular marking shows in the flower as well. Dew/water droplets also collect around the edges of the leaves and pods.
The leaves also have interesting veining, radiating out from the center to the margins. It appeared that these veins were singular and straight until very close to the edges, where they split off into usually only one or two additional branches. On closer examination, I saw that the entire leaf was “woven” with very subtle veins throughout the whole.
The submerged leaves are often highly dissected or divided. This has the advantage of creating a very large surface area for absorption and photosynthesis. It also minimises water resistance and hence, potential damage to the leaves since moving water (currents and waves) can be damaging to the leaves of the plant.
