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.
The correct option is B.
Leather shoes are made form leather, which is a natural polymer. Leather is usually obtained by tanning the hides of animals, especially cattle. Natural polymers refer to those polymers that are obtained naturally from nature. Examples are wool, silk, leather, keratin, etc. Synthetic polymers on the other hand are man made, they are produced by combination of chemical substances in the industries. Examples are plastics, polyethylene, nylon, etc.
Answer:
Digestion
Explanation:
The diagram is attached below
The diagram represents a complex sugar that is linked to an enzyme. With the addition of water, this complex sugar is broken down into two simple sugars.
This process is called digestion, which is the breakdown of large insoluble molecules into small molecules that the body can use for energy. The catalyst in this picture speeds up or facilitates the reaction. It could be an enzyme such as amylase.
The water level fell because of eccesive use of underground water and due to that the water debt increased
