Answer:
For functioning of heart, circulatory and execratory systems are required.
Explanation:
It requires at least two body systems to perform the function because the functions does not be completed solely, it requires coordination among systems which help them to fulfill their task. For example, the function of the heart requires circulatory system and execratory system for the pumping of blood throughout the body. it is an involuntary action which is not control by nervous system.
Answer:
A: Discovery of DNA as the genetic material
Explanation:
DNA is the genetic material and stretch of DNA that codes for a specific protein is called as gene. Discovery of DNA as genetic material provided the physical proof of Mendel's factors that were responsible for transmission of genetic traits in his experiment.
Discovery of DNA as genetic material also established that genetic variations among individuals of the species as described by Darwin are due to minor differences in their DNA molecules.
Hence, discovery of DNA as genetic material led to acceptance of both Mendel's law and Darwin's theory.
Hello! :)
It would take forever listing all the animals that have adaptations that helps them survive in their environment.
Natural selection is the process by which individuals with characteristics that are advantageous for reproduction in a specific environment leave more offspring in the next generation, thereby increasing the proportion of their genes in the population gene pool over time.
Hope this helped and I hope I answered in time!
Good luck!
