explain why eating down a food chain," vegetables instead of meat for example, is more energy efficient
Brut [27]

Answer:

I would say that meat is more energy efficient than vegetables because meat have more calories than vegetables do. Calories equal energy. For example, vegetables have an average calorie of 10 - 90 calories. While meat has 100 - 1200 calories. So, if calorie equals energy, I would say that calories are the reason why meat has more energy in it.

Lesions to the medial geniculate of the ___________ block conventional auditory fear conditioning.
marissa [1.9K]

Lesions to the medial geniculate of the amygdala block conventional auditory fear conditioning.

Medial geniculate

The medial geniculate body (MGB) is a collection of nuclei that receives heavy input from the IC and acts as a key synaptic junction on the routes that carry data to the cerebral cortex's auditory regions.

One should also think about how the medial geniculate's structure might affect its possible roles as a relay nucleus given the substantial studies on its anatomy. It is not in question that the MGv, which is the lemniscal portion of the MGB, "relays" accurate auditory information to the primary auditory cortex.

Consider the case of in vitro evolution used to generate RNA molecules with ligase activity. If the researchers repeated the inv
nekit [7.7K]

Answer:

The answer is E.

Explanation:

In vivo or in vitro evolution (Directed Evolution) is a technique used by genetic scientists to push the change in nucleic acids or proteins in a specific direction to get the end results that they want.

And high-fidelity polymerase is used to get a replica of the target DNA that has less errors.

So the situation given in the question where researchers use a higher-fidelity DNA polymerase in vitro evolution, the mutation rate would most likely be lower because of the high-fidelity DNA polymerase.

I hope this answer helps.
