Answer:
The correct answer is - Fire causes the cone of an older jack pine tree to open up and release seeds.
Explanation:
Fire ecology is a branch of ecology that deals with the involvement of the fire in the ecosystem and its effects on the ecology and how it deals with the natural processes.
Naturally generated fire in forest ecosystem especially in the forests with the pine trees are useful. The coniferous trees like pine trees show adaption to the fire. These trees (pines or jack pines) open up and release the seeds from the cones caused by fire as it melts the covering made up of resin of the woody cones.
Answer: d. tundra
Explanation:
Polar bears are present only in the Arctic tundra biome. The most important areas for polar bears in the arctic are are the edges of pack ice where the wind and water interact, which createsa constant refreezing and melting network of leads (open spaces in the sea ice) and ice patches.
A polar bear has a fat layer under the skin that helps it stay warm and the big paws help a polar bear walk through the snow.
Hence, the correct option is D. Tundra.

Answer:
Option 2.
Explanation:
The fossil proof for the human-chimpanzee last common ancestor (LCA) is rare and scarce due to: These apes lived in an environment of tight or narrow range that was not preserved well in the fossil record.
Fossil monkeys and prosimians were rare in the Miocene, however, apps were normal and dominant. Option 1 is inaccurate.
The majority of the apps known from the mid-Miocene are Old World monkeys, who are from an unexpected Linnaean family in comparison to we are is an incorrect statement so it is inaccurate.
The LCA lived in the Paleocene, a time from which we have got a number of the fossil record. so Option 3 is incorrect
Thus, the correct answer is - These apes lived in an environment of tight or narrow range that was not preserved well in the fossil record.
