The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
So an object denser than water will sink
Answer: a. adaptation
Explanation:
Sensory adaptation can be define as the reduction in sensitivity to a stimulus after a constant exposure to the stimulus. When the awareness and sensitivity towards the constant stimulus reduces, then the attention of the receives diverts to another stimulus present in the environment around it.
The given situation demonstrates the sensory adaptation this is because of the fact that Sariah developed the sensory adaptation towards the constant stimulus that is chirping. Now her attention diverts and she was able to talk to her friends, and she lost awareness of chirping although it was still there.
Answer:
Option A, accumulation
Explanation:
As we can see in the image, the water gets heated and convert its pahse from liquid to gas i.e from liquid water to water vapor. As it rises above, it condenses and converts from water vapor into liquid water. The liquid water then moves in the downward direction and collects at the base. This process of collection at base can be related to accumulation of running water.
Option A is correct
Answer:
C, recycle, but if I could choose two it would be reuse.
Reasoning:
Reusing things and recycling things are both useful for the community.
Mutations and natural selection cause adaptations. Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations.
Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment.
