I would say B, as morality is knowing the difference between right and wrong, and I think A would be an ethical issue
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.
A because it is used to treat known diseases.
Answer:
The term which can be used for this species is psychrophile. Psychrophilic bacteria are the bacteria which love to grow at low temperature. The optimum they like to grow is 15°c and the highest temperature they grow is 20°c.
The minimal temperature a psychrophile grows is zero degree Celsius so a psychrophile can grow easily at refrigeration temperature which is 4°c. Phychrotrops are bacteria which can grow at cold temperature but tends to grow well above 15-20°c.
Therefore according to this question, there was no growth at 37°C and 50°C, very slight growth out on the benchtop, and abundant growth at refrigeration which determine that the species is a psychrophile.
