Uncle Mel mentioned having difficulty sleeping. If he was prescribed a medication that targeted serotonin, such as a SSRI (selec

tive serotonin reuptake inhibitor), it would also help with sleep. There is another chemical secreted in the brain that causes sleepiness. It is characterized as a hormone rather than a neurotransmitter. Name this hormone.

Answer:

Melatonin

Explanation:

     Melatonin is a hormone linked to the circadian cycle, ie, the way the body organizes its functions when we are awake and during sleep. The substance begins to be produced in the pineal gland as day goes on to help the body prepare for sleep. It reaches its maximum level when we are sleeping. As the sun rises and the light returns, the gland reduces the production of melatonin, which signals that it is time to wake up.

Answer:

The hormone is seretonin.

Explanation:

Seretonin is a hormone that is synthesized from the hydroxylation of amino acid tryptophan resulting in the formation of 5-hydroxytryptophan which further undergo de carboxylation to form seretonin.

 Seretonin is found in both myentric neuron and seretogenic neuron.Seretonin helps to control mood,desire for food and sleep.

  Selective seretonin reuptake inhibitors are used as antidepressent that interfere with the re absorption of seretonin thereby maintaining high level of seretonin in the synapse.

inessss [21]

Answer:

negative, inhibition

Explanation:

The experiment in the illustration shows that early succession plants have a <u>negative </u>effect on the late succession plants, and the observation is most consistent with the <u>inhibition</u> model of succession.

<em>That the late succession plant thrives better in the absence of the early succession plants means that the early succession plant has been impacting the growth of the late succession plant negatively. This is consistent with the inhibition model of succession.</em>

There are 3 different models of succession. These include;

  1. Facilitation model in which colonists modify the environment to favor the growth of later successional species.
  2. Tolerance model in which early colonists' modification of the environment has no positive or negative impact on the growth of later successional species.
  3. Inhibition model in which early colonists modify the environment to inhibit the growth of later successional species.

Describe how population studies can be conducted in a school garden
daser333 [38]

Answer:

Population studies look at factors for one individual species.

Explanation:

In a garden, there are multiple species of plants growing. You could study different factors of each population, which is just all the individuals of one species in an area. For example, you could study how adding fertilizer affects the growth of tomato plants. To do this, you would have some tomato plants in the garden that have fertilizer added to the soil and some that don't. At the end of a certain period of time, maybe a month, measure the plants, find the average height and compare their growth. This is just one example, but there are lots of different things you could study.

At this time in the earth's history, scientists and others are very concerned about climate change. What is the best explanation
torisob [31]

Answer:

Rise of population and over-consumption resources are key factors of  climate change.

Explanation:

  • The fact that climate change is real and is happening at a very fast rate. The impacts of which can be seen in terms of the increase in sea levels.  
  • The rise in global average mean temperatures, an increase in the melting of Greenland and Antarctic glaciers. The exposure of barren land beneath the antarctic continent.
  • Therefore the scientific community s very concerned about the massive depletion of resources and the exposure of the earth's surface to solar radiation.

How is the message from the brain sent in response to the stimuli?
ivolga24 [154]
When a stimulus is being detected, this stimulus is being sent to the brain through the sensory neuron, going to the spinal cord then to the brain. The brain then interprets these stimuli, and responds to it using the motor neurons. These are the neurons that are responsible in our actions depending on the stimuli we are exposed to. Hope this helps.
