Blubber is a thick layer of fat (adipose) tissue. Animals store extra digested food in the form of adipose tissue, which contains molecules called lipids.
ANSWER : have a specific shape related to their specific function
Answer: hybridisation between related species is unlikely to contribute to adaptive speciation.
Explanation: any population has natural genetic variation. The available resources are insufficient for all plants (and conversely, not all offspring survive). Natural selection favours variations better suited to the conditions.
Although hybridisation is more common in plants than animals, and can lead to speciation, adaptive radiation from an ancestral species is the general response to environmental change, such as from rainforest to savanna. There is low probability of selective advantage from hybridisation of two ancestral species adapted to niches within the original habitat when the conditions in those niches changes significantly.
Answer:
Reforestation
Explanation:
Reforestation will help regrow deforested areas of forests and help filter more carbon dioxide, one of the greenhouse gases responsible for climate change and global warming, and produce more oxygen for the rapidly growing population of humans. Reforestation will also help bring back wildlife and preventing animals to go extinct. Once the forest grows back, the roots of the trees will prevent the soil from soil erosion and polluting fresh water rivers and ponds.
