Answer:
The history of GIS all started in 1854. Cholera hit the city of London, England. British physician John Snow began mapping outbreak locations, roads, property boundaries, and water lines.
John Snow’s Cholera map was a major event connecting geography and public health safety. Not only was this the beginning of spatial analysis, but it also marked the start of a whole field of study: Epidemiology – the study of the spread of disease.
To this date, John Snow is known as the father of epidemiology. The work of John Snow demonstrated that GIS is a problem-solving tool. He put geographic layers on a paper map and made a life-saving discovery.
Explanation:
Answer: The endocrine system sends chemicals called hormones through the bloodstream to change short-term and long-term activities in the body
Explanation: Endocrine system is a system made up of glands that produce and secrete chemical signal called hormones which travel through the bloodstream to the target cell where they exert their effects.
A hormone is a chemical messenger secreted by an endocrine gland. Long-term activities in the body influenced by hormones include growth and development.
The correlation between thirst and kidney function is the following:
Thirst is the regulator of the state of hydration, necessary to eliminate the osmotic load, it can help preserve kidney function.
The instantaneous perception of osmolarity in the blood allows us to generate the sensation of thirst.
In other words, this sensation is in turn caused by a high concentration of osmolytes (compounds that affect osmosis, or the way it is measured, osmolality or osmolarity) or by hypovolemia.
The receptors that control cellular dehydration are called osmoreceptors and are located in the lateral preoptic area.
Osmoreceptors detect this decrease in cellular water and trigger thirst, as well as the release of Anti-Diuretic Hormone into the bloodstream.
Antidiuretic hormone helps regulate the amount of water in the body by controlling the amount of water excreted by the kidneys.
Therefore, we can conclude that the sensation of thirst appears the sodium concentration is higher than normal, when drinking water, the concentration gradient is reduced, which allows the normal functioning of kidney function.

Law of segregation states that <span>gametes carry one allele for each trait
As it states that
</span>that during the production of gametes the two copies of each hereditary factor segregate<span> during the production of gametes</span> so that offspring acquire one of the two allele from each parent
so option C is correct
hope it helps
