Which statement describes one of Wegener’s ideas that contributed to the theory of continental drift? The continents drifted apart due to repeated meteor impacts.
The continents were once connected as one landmass.
The continents have moved apart very quickly due to earthquakes.
The continents are magnetically pulled toward or pushed away from one another.

Option B

The continents were once connected as one landmass.

Explanation:

The theory of continental drift suggests that all the continents on the planet were once connected, forming a supercontinent. However, over time they drifted apart as a result of some internal forces of the earth.

The most appropriate option that shows this is option B: The continents were once connected as one landmass.

This statement describes one of Alfred Wegener's ideas that suggests that a very long time ago, the continents were once connected in a landlocked mass. The fact that the continents are separated now shows that the continents are continuously shifting position on the earth's surface.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
