Answer:
Explanation: Without gene duplication, mutation of genes would not exist. This would prevent organisms from adapting to their environment, making survival much more difficult if not impossible.
Answer:
The species that will be most similar to humans will be
1. rhesus
2. pigeon
3. fruit fly
Explanation:
Evolution can be described as the process in which different organism evolve from common ancestors over a long period of time. Evolutionary studies show that some organisms have more shared characteristics as compared with other organisms. These organisms with common characteristics are believed to be closer to one another and evolved from the same ancestors.
In the above question, as there is only one difference between the cytochrome c of humans and rhesus, hence rhesus is the closest to humans. Pigeons has lesser number of differences than fruit fly, hence it is second on the list. Fruit fly has the maximum differences hence it is placed last.
Answer:
B) venous blood and aveolar
Explanation:
Partial pressure of carbon dioxide in the aveolar is the lowest, it is 40mmHg (millimetre mecury ) while the partial of carbon dioxide in venous blood is the highest at 45 to 50 mmHg (millimetre mecury)
20. Cell Membrane 19. Mitochondria 18.<span> Osmosis</span>
Answer: The question is incomplete therefore, the options are gotten from another websites.
demonstrating?
A. mechanical energy
B. potential energy
C. kinetic energy
D. two of the above
The correct option is C.
Kinetic energy.
Explanation:
It is kinetic energy because the chemical energy stores in food is converted to kinetic energy and this is because kinetic energy is the energy in motion.
When a person is running, the energy the person is using is kinetic energy because is the energy the person possess by virtue of his body in motion and it is the energy required to accelerate a body with mass from rest.
