Answer:

Pineal gland

Explanation:

The suprachiasmatic nucleus is the paired nucleus made of about 1000 neurons each in the hypothalamus. The suprachiasmatic nucleus is involved in maintaining the endogenous clock or the internal clock.

The suprachiasmatic nucleus controls the circadian rhythm by controlling the amount of melatonin. The melatonin is produced by the pineal gland from the serotonin and tryptophan precursors.  The hypothalamus thus controls the amount of the melatonin by regulating the pineal gland.

Thus, Pineal gland is the correct answer.

If a person had a low level of neurotransmitters, how could this affect the person?
AveGali [126]

Answer:

B

Explanation:

Neurotransmitters such as acetylcholine, epinephrine are important at a neuron-neuron junction called synapses. When an impulse reaches the end of one neuron, at the synapse, it causes the release of neurotransmitters from synaptic vesicle that diffuse across the synapse and when they bind to their reports on the other end. An impulse is then generated on the subsequent neuron that travels down the axon to the next synapse.

Crazy boy [7]

Answer:

Anthropoids lived for approximately 0.86% of the total time.

Explanation:

  • Anthropoids are the higher developed organisms that includes apes and ape mans.
  • The age of earth is 3500 million and anthropoids lived for about 30 million years.
  • By the simple calculations we can find out the data in percent which gives us the result nearest to 0.86%.
  • That means 0.86% of 3.5 billion year is equivalent to 30 million years (time that was lived by anthropoids).

Consider the diagram of a eukaryote and a prokaryote. According to cell theory,
Artemon [7]

both are single cells that carry out the functions of life

Explanation:

Both eukaryotic and prokaryotic cells are single cells according to the cell theory and they carry out the functions of life.

  • The cell theory postulates that all living organisms are made up of cells and that the cells are the basic organizational unit of life.
  • It also proposes that all cells arise from pre-existing cells.

Eukaryotic cells differs from prokaryotic cells in that they have true nucleus and membrane bound organelles.

Despite this seeming different, both cells are able to carryout different life functions as unit and when they combine together, they advance into higher organization of life.
