Hello,
Placing a rat in a cage where electrical shocks over which the rat has no control are occasionally administered through the floor is a way to create → <span>learned helplessness
Good luck :)</span>
Explanation:
Bedbugs are parasites that rely on blood to survive. They can feed on the blood of any mammal, although they appear to prefer the blood of humans. They are attracted to the warmth surrounding mammalian bodies and the carbon dioxide present in breath expiration. It is usually these factors that guide bedbugs to locate a suitable host for feeding. DOES THIS HELP?
Answer:
An ecosystem is biotic, not abiotic.
Explanation:
First, an ecosystem is a biological community of interacting organisms and their physical environment. Second biotic factors are nonliving things whereas biotic factors are living things in an ecosystem you have your producers or plants which then will be consumed by the primary consumers. With the primary consumers feeding the next group of consumers and then the next and then after they die they fertilize the ground allowing the producers to grow as it completes the circle of life.
Answer:
Explanation:
In a lake, oxygenic phototrophs produce new organic material as well as O₂. If primary production rates are very high, the resultant excessive organic matter production can lead to bottom-water O₂ depletion from respiration and the development of anoxic conditions. This in turn stimulates anaerobic metabolisms, including anaerobic respirations and fermentations.
Organic matter that is not consumed in surface layers sinks to the depths and is decomposed by anaerobes.
For B. It is CAC
For the rest there needs to be a codon table for us to see
