In what trophic level do most humans belong? And why?

Biology
1 answer:
klio [65]2 years ago
8 0

Answer:

Not all humans belong to the same trophic level. This is due to the dietary choices each human makes.Next come the omnivores that eat a mixture of plants and herbivores. That's where humans rank, with a trophic level of 2.2.

Explanation:

Many humans are omnivores, meaning they consume both plant and animal material. Thus, they may be on the third or even fourth trophic level. For example, if you consume beef (cows are herbivores), you are a part of the third trophic level. If you were to eat salmon though, salmon consume other fish, and this would mean you are a tertiary consumer on the fourth trophic level.

Vegans and vegetarians who do not consume fish or meat of any kind are primary consumers. They belong on the second trophic level.

KIM [24]

Answer:

The correct answer is option a, that is, the thrM and thrN would be transcribed at high levels in comparison to non-mutant.

Explanation:

Based on the given information, in the existence of thorain the expression of thrM and thrN will be prevented as thorain functions as a negative regulator. In case, if the gene, which codes for thorain, that is, thrL gets mutated, the coding for the functional thorain would get prevented.  

With the encoding of the non-functional thrL protein, there would be an enhancement in the expression of thrN and thrM genes and it will get transcribed at higher levels in comparison to the non-mutant or the wild-type.

Since urological or gynecological exams rarely result in any sexual arousal and unwanted sexual advances produce only revulsion,
nignag [31]

Answer:

mind

Explanation:

  • An area present in the body that is highly sensitive and thus the stimulation of which may result in sexual arousal is termed as an erogenous zone.
  • There are different erogenous zones present in the body an all these zones vary in their sensitivity and these zones mainly provide a sense of pleasure upon stimulation.
  • However, the ultimate erogenous zone is the mind and one can say that it is a hidden erogenous zone as it is not exposed to tactile sensations like the other areas.
  • This is the reason why during urological or gynecological exams or unwanted sexual advances a person doesn't get sexually aroused even though the same areas are being touched.
