Answer:
Invertebrates: Do not possess a backbone and doesn't have an internal skeleton. Has an exoskeleton. Are generally smaller than vertebrates. Possess an open circulatory system. The majority have compound eyes. Includes radial or bilateral body symmetry. Presence of a simple and unorganized nervous system. Mode of nutrition includes Autotrophic, Parasitic, and Heterotrophic. 95% of animal species are invertebrates. Flatworms, arthropods, sponges, insects are few examples of Invertebrates.
Vertebrates: Possess a backbone and has an internal skeleton. Does not have an endoskeleton. Larger than invertebrates. Possess a closed circulatory system. Do not have compound eyes. Has bilateral body symmetry. Presence of complex and highly specialized organ systems with specific functions. The mode of nutrition is usually heterotrophic. 5% of animal species are vertebrates. Mammals, fish, reptiles, amphibians, and birds are examples of Vertebrates.
<span> A. Insects (living) carry seeds (living)to new places, which allow new plants to grow.
B. People(living) plant trees(living) in a city park.
C. A drought dries up a river(not living), so deer(living) have less water to drink.
D. A fungus(living) causes a grove of trees(living) to die.
The answer is C because river is the only not living(abiotic) factor in these case</span>
Cell theory meets the definition of a theory because it's been tested over a long period of time, and scientists have plenty of evidence to support this theory.
However, it doesn’t seem to meet the criterion of a scientific law. Scientists only know about life on this planet, so the theory may not be universal if life is found on other planets. In addition, scientists don’t have much data on the earliest forms of life on Earth.
Hope to help :)
