Answer:
B. interconnected
Explanation:
All the systems in our bodies (humans are indeed animals) are connected with each other to create a functional being. The blood flows throughout the body, providing nutrients; the bones support the structure and protect the heart and lungs. They work together.
Why not A: The systems are all completely necessary. There's nothing extraneous in our bodies, because extraneous stuff takes up energy, and our biology is incredibly economical.
Why not B: They're not interchangeable. How would you like your bones to turn to blood? Uh-huh.
Why not D: They interact with each other consistently, so they're not separate or segregated.
It should be 1830 or a possibility of 1850
Answer:
Earthworm - have a coelom and a closed circulatory system.
Scallops or clams - has a mantle and an open circulatory system.
Starfish - has an endoskeleton made of calcium-rich plates.
Spider - exhibits the phenomenon of molting.
Explanation:
Earthworm belongs to Phylum Annelida. They are metamerically segmented, triploblastic and bilaterally symmetrical. They have a closed circulatory system and a coelom (true body cavity).
Scallops or clams belong to Phylum Mollusca, the second largest animal phylum. They are coelomate, triploblastic, bilaterally symmetrical organisms having an open circulatory system. They have a calcareous shell covered body with a distinct head, muscular foot, visceral hump and a mantle (soft and spongy layer of skin) over the hump.
Starfish belongs to Phylum Echinodermata, which consists of exclusively free-living marine organisms. They have an endoskeleton made up of calcium carbonate structures. They are coelomate, triploblastic and have a water vascular system that is used for respiration, locomotion, food capture and transport.
Spiders belong to Phylum Arthropoda. They have chitinous covered segmented bodies, jointed legs and exoskeletons (hard external shells). Arthropods periodically shed their exoskeletons or shells in order to grow, this process is called molting. They are coelomate, triploblastic, bilaterally symmetrical organisms having an open circulatory system.
Answer:
I'm pretty sure its 50% and 50% :)
Explanation:
Answer:
The most appropriate way of sharing the results is to publish in a scientific journal for peer review. So the answer is 'B'.
Explanation:
In order to validate your results in the scientific community, it is best to publish in a <em>scientific journal</em> and get it peer reviewed. When the article is peer reviewed, other scientists of <em>higher caliber</em> verify your experiment and results and then give their verdict to the outside world.
Newspapers sometimes also <em>publish rumors</em>. So there is no guarantee what gets published is true. the students are still learning and cannot appreciate the full extent of your work.
