Answer:
Tissues
Explanation:
Tissues are groups of cells working together to complete a specific function.
Examples are brain and muscle tissue.
Answer:
The Right ventricle and the Left atrium.
Explanation:
The pulmonary circulation loop starts in the right ventricle, where the
deoxygenated blood is. From there, the blood goes through the pulmonary semilunar valves and into the pulmonary trunk. The pulmonary trunk divides into two arteries, the left, and right pulmonary arteries. These arteries conduct the deoxygenated blood to the capillaries in the lungs where we exchange the CO₂ for O₂. Then, the oxygenated blood goes to the pulmonary venules and the pulmonary vein. The pulmonary vein conducts the oxygenated blood from the lungs to the left atrium of the heart. Lastly, the blood goes to the left ventricle, where the systemic circulation starts.
Answer: Genetic variation describes naturally occurring genetic differences among individuals of the same species. Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation. And there are the reasons.
Yes, quite frankly it is possible to find a same gene if you're in the same class of species, but finding the protein....I believe that's impossible because in every type of gene, you have the same proteins that make you function the same way. Without them you wouldn't be able to function properly.
If I found the same gene in all organisms that I've tested, I would be intrigued because that would be a giant step in evolution. My reason for this answer is because if you have the same gene that would technically mean we all specifically came from the same species of animals.
No, that's not true because other characteristics would eventually help us in many things, studies would help us get our brain much stronger and the intelligence level would be extraordinary.
