What role does natural light exposure during the day play in improving sleep? it helps to regulate circadian rhythm. it discoura
yuradex [85]

Answer: It helps to regulate circadian rhythm

Exposure to natural light during the day helps regulate the circadian rhythm, which improves sleep pattern. The term circadian rhythm refers to our biochemical, physiological and behavioral processes in approximately 1 full day cycle. Circadian rhythm plays an important role in controlling when we fall asleep and when we wake up.

During day light, the secretion of melatonin or sleep hormone is suppress by melanopsin that keeps people awake and alert. Nevertheless, during nighttime, melanopsin stimulates the release of melatonin to signal sleeping time. Therefore, this hormone works the entire day and has direct effect on the circadian rhythm, which acts as a regulator of our biological clock.

professor190 [17]

1. Answer: C

Explanation: Species that are inclined to clumping means they are more likely to cooperate in tasking such as gathering food. However, evenly distributed population means there is competition between individuals hence the need to their own space and territory from the other individual.

2. Answer: B

Explanation: While the clumped up populations may be inclined to cooperate in tasks such as food gathering, such distribution results to increases intraspecies competition especially during scarcity. This is because the individuals are close together – which is also advantageous during mating season.

3. Answer: A

Explanation: Type 3 survivorship curve is characterized by a high mortality rate early in the life of the species which gradually progresses to a low mortality rate for the individuals that survive the early stages of life. These species, therefore, bear a lot of offspring most of which will not make to adulthood.

4. Answer: B

Explanation: If the death rate of a population is higher than the birth+ immigration rate, then the population must be decreasing. This can be demonstrated by a growth curve of a population such as that of bacteria. The population starts decreasing due to increased competition for reduced resources after reaching carrying capacity  - depicted by the stationary phase.
