ANTONII [103]
The light-dark cycle caused by the rising and setting of the sun is responsible for what are called circadian rhythms. These are biological processes that show a cycle of around 24 hours, the time between consecutive rising of the sun. Experiments have shown that without the external cue of sunlight, the circadian rhythms of organisms tend to break down. These can be reset by being re-exposed to these cues. Jet lag is due in part to a re-setting of the circadian rhythm, as you travel to a different time zone, your body has to become used to a different timing of night and day. <span>  </span>

Answer:

Explanation:

Due to the prevalence of malaria in Africa, the allele for sickle cell anemia (HbS) provides a selective advantage. That's why it remains in the population.

A normal African person (HbAHbA), with normal haemoglobin, will not die of anemia, but will die of malaria.

An African person with sickle cell anemia (HbSHbS), with abnormal haemoglobin, will die of anemia.

A heterozygous African person (HbAHbS), with half of his red blood cells (RBCs) being normal and the other half being sickle-shaped, will neither die from anemia, nor malaria since the plasmodium will be incapable of completing its life cycle in the abnormal RBCs.

Thus heterozygous African people will grow, reproduce and pass on the HbS allele to the next generations.

Answer:

Thyroid hormones      

Explanation:

Animals and people exposed to pesticides such as insecticides, fungicides, and herbicides, have shown to be affected by their effect on the thyroid. These chemicals can produce endocrine alterations acting as thyroid disrupters. They affect many mechanisms in the organisms such as inhibition of thyroid iodine uptake, <u><em>interference with the thyroid hormone receptor</em></u>, binding to transport proteins, among others. They cause toxicity in the functioning of the hypothalamic-pituitary-thyroid axis.

There are many studies that associate thyroid diseases with exposure to organochloride pesticides. Significant alteration in the TSH, T3, and T4 levels have been expressed by people directly or indirectly exposed to the chemicals.
