Answer:
Homologous chromosomes
Explanation:
Homologous chromosomes are two pieces of DNA within a diploid organism carry the same genes, one from each parental source
i think it is a 417
b. False
a. True
This is somehow true. If the climate before, thousands of years ago was in harsh conditions; the same conditions today many organisms would not survive. Hence, certain climate conditions is needed for an organism complex such as mammals, humans and the similar organisms to thrive.
Answer:
A. true (just took test)
Answer: Option D
Explanation: Natural selection come into action when some change takes place in the environment which affects the survival of the organism. Here the change is addition of antibiotics. So the bacterial cells which were able to adapt to the change, they survived and rest were killed. These resistant bacterial cells would pass on the genes to next generation and gradually population of resistant bacteria would increase.
Answer:
To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
B) commensalism
C) symbiosis
D) interaction
The right option is; A) coevolution
Coevolution is the term that refers to a change in one species that results from a change in another species that it interacts with.
Coevolution is a process of mutual evolutionary change that takes place between two or more organisms as they interact with one another. Under this process, any change in any of the organisms that are involved in the interaction influences others evolution. Coevolution can happen in interactions such as between host and parasites, predators and prey and mutualism.
