Answer:
Plucking
ExplantionPlucking is the method through which erosion happens during glaciations. The movement of ice and glaciers scrapes along the rock that surrounds it while pulling ways the pieces of the foundation that results in corrosion.
Glacier causes erosion in two ways it can be either by plucking or abrasion, plucking occurs when the sediments pick up the glacier. They then freeze below the glacier thus being always carried by ice when it is flowing. Abrasion happens when the glaciers scrapes towards the earth’s service.
Answer:
predictions is the correct answer.
Explanation:
- Scientific models must be able to generate predictions.
- Scientific models refer to a conceptual illustration of a method of concepts, events or methods which are utilized to explain and predict the role of a system.
- Scientists normally use Scientific models to carry out study and to describe the outcomes of their analysis.
- A reliable and efficient scientific model should be adequate to make perfect predictions.
The right answer is c. anther; stigma.
Pollination is the fertilization necessary for sexual reproduction of flowering plants. It corresponds to the transport of the pollen grains produced by the male organs of the plant (anthers) towards the female organs (stigmas). The wind, some birds, some small rodents but mostly insects provide this service. The small population of pollinators is primarily insects and, essentially, wild or domestic bees.
