Answer:
Adaptive radiation occurs within a single lineage
Explanation:
Adaptive radiation generally occurs when an organism enters a new area and different traits affect its survival. An adaptive radiation is a burst of evolution, creating several new species out of a single parent species, which simply means that adaptive radiation occurs when a single lineage produces many descendant species. Adaptive radiation is considered to be a rapid process, where adaptation from a recent common ancestor takes place in a short period of time (with respect to geological time, of course).
Adaptive Radiation refers to the process causing a rapid rate of speciation, within a single lineage, particularly when a single species invades various diverse environments. This process leads to multiple new species evolving from a single ancestral species. An established example illustrating this concept is Darwin's study of finches on the Galapagos Islands.
The correct statement about adaptive radiation is that it occurs within a single lineage. Adaptive radiation is a process that prompt multiple speciation events in a relatively short time, particularly when a single species invades different and diverse environments. Each of these invasions results in adaptational and evolutionary changes, leading to multiple new species originating from a single ancestral species.
For instance, Charles Darwin's study of finches on the Galapagos Islands is a classic example of adaptive radiation. The different beak shapes evolved over time in response to the different food sources available on the separate islands within the archipelago.
b. They are composed of molecules that contain carbon-carbon bonds.
c. They undergo chemical reactions to use energy they acquire from the environment.
d. They do not require catalysts to sustain their living state
Answer: b. They are composed of molecules that contain carbon-carbon bonds.
c. They undergo chemical reactions to use energy they acquire from the environment.
Living things includes all the organisms that display features which make them distinct from non-living organisms. The living organisms have an organized structure, they are composed of cells, they require energy to survive or sustain existence, they are able to reproduce and they exhibit ability to grow.
They are composed of molecules that contain carbon-carbon bonds: Carbon is the main component present in all living things. They make up the organic biomass of these living organisms.
They undergo chemical reactions to use energy they acquire from the environment: The plants traps sunlight energy and converts it into food and lastly into chemical energy in the form of ATP. This ATP is used as a energy reservoir for metabolic processes occurring in the plants. Therefore, energy is generated after chemical reactions.

Answer;
- Sensory receptors
After receiving a stimulus, the sensory receptors send(s) signals to the appropriate area of the body.
Explanation;
-Sensory receptors are structures that reacts to a physical stimulus in the environment, whether internal or external. They are sensory nerve endings that receives information and conducts a process of generating nerve impulses to be transmitted to the brain for interpretation and perception.
-The sensory receptors include those for tactile sensations, such as touch, pain, and temperature, as well as those for vision, hearing, smell, and taste.
