Answer:
En el hemisferio sur el verano comienza en diciembre y finaliza en marzo, mientras que el invierno comienza en junio y finaliza en septiembre.
Perú se encuentra en el hemisferio sur, con lo cual el verano comienza el 21 de diciembre y finaliza el 21 de marzo, mientras que el invierno comienza el 21 de junio y termina el 21 de septiembre.
El afelio indica a la mayor distancia posible en la órbita de un planeta con respecto al Sol, mientras que el perihelio refiere a la menor distancia posible (es decir, el punto de mayor cercanía posible) entre la órbita de un planeta y el Sol. En la Tierra, el afelio se produce a comienzos de julio, donde nuestro planeta dista aproximadamente 152 millones de kilómetros con respecto del Sol, mientras que perihelio se produce a principios de enero, donde la Tierra dista aproximadamente 147 millones de kilómetros con respecto del Sol.
La caída de lluvia es un fenómeno independiente a la estación del año, es decir, la lluvia caída en enero o julio no modifica que en el hemisferio sur nos encontremos en verano e invierno, respectivamente. En algunas regiones las lluvias se concentran en un determinado período del año, lo cual es un fenómeno meteorológico que tampoco tiene incidencia sobre la estación del año.
in 1907, Duncan preformed a series experiments in which he attempted to measure the weight of a soul as it left a dying person in his experiment McDowell cool place a dying person on a scale and measure their weight immediately prior to the following death. McDowell determined the change and weighed approximately 21 grams for the experiments he concluded the soul exists and has mass what is the fundamental scientific flaw in his conclusions
Answer:
The flaw is that he is studying pseudoscience (fake science) and he did not repeat his experiments in any form of trials.
Which monomer serves as the building block of glycogen, a polymer made up of many glucose molecules? Choose 1 answer: (Choice A) Amino acid (Choice B) Monosaccharide (Choice C) Nucleotide (Choice D) Steroid
The monosaccharide serves as the building block of glycogen, a polymer made up of many glucose molecules. So, the correct option is (B).
What is Polymer?A polymer is defined as a substance or material consisting of very large molecules known as macromolecules, which are made up of many repeating subunits. Due to their wide spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life.
During the process of polymerization, polymers are formed in which smaller units known as monomers are joined together with the help of covalent bonds. Polymers are of four types:
1. Natural
2. Synthetic
3. Addition
4. Condensation
In above given example, Monosaccharide which is glucose is the monomer which is joined together to from glycogen which is a polymer.
Thus, the monosaccharide serves as the building block of glycogen, a polymer made up of many glucose molecules. So, the correct option is (B).

A. parasympathetic
B. somatic
C. peripheral
D. autonomic
Answer:
autonomic
Explanation:
edg 2020
Control of glands and the muscles of internal organs is a function of the autonomic nervous system.
What is autonomic nervous system?The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic, and enteric.
The sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS) contain both afferent and efferent fibers that provide sensory input and motor output, respectively, to the central nervous system (CNS).
Activation of the SNS leads to a state of overall elevated activity and attention: the “fight or flight” response. In this process, blood pressure and heart rate increase, glycogenolysis ensues, gastrointestinal peristalsis ceases, etc.
Therefore, Control of glands and the muscles of internal organs is a function of the autonomic nervous system.

Can an enzyme be recycled? Explain.
Answer:
Enzymes serve as catalysts to many biological processes, and so they are not used up in reactions and they may be recovered and reused. However, in a laboratory setting, reactions involving enzymes can leave the enzyme unrecoverable. This process makes the enzyme at once less reactive but more stable.

Mercury is a toxin that is of significant concern due to biomagnification. Explain how mercury found in an aquatic environment can accumulate in
biomagnification, and explain how limiting consumption of large predatory fish, such as swordfish, may be necessary for individuals trying to avoid high
mercury concentrations
Answer: Mercury has been well known as an environmental pollutant for several decades. As early as the 1950's it was established that emissions of mercury to the environment could have serious effects on human health. These early studies demonstrated that fish and other wildlife from various ecosystems commonly attain mercury levels of toxicological concern when directly affected by mercury-containing emissions from human-related activities. Human health concerns arise when fish and wildlife from these ecosystems are consumed by humans.
During the past decade, a new trend has emerged with regard to mercury pollution. Investigations initiated in the late 1980's in the northern-tier states of the U.S., Canada, and Nordic countries found that fish, mainly from nutrient-poor lakes and often in very remote areas, commonly have high levels of mercury. More recent fish sampling surveys in other regions of the U.S. have shown widespread mercury contamination in streams, wet-lands, reservoirs, and lakes. To date, 33 states have issued fish consumption advisories because of mercury contamination.
These continental to global scale occurrences of mercury contamination cannot be linked to individual emissions of mercury, but instead are due to widespread air pollution. When scientists measure mercury levels in air and surface water, however, the observed levels are extraordinarily low.
Explanation:
Mercury can accumulate in biological systems and then pass to humans after consumption (in this case, fish consumption).
What is bioaccumulation?Bioaccumulation can be defined as the process of accumulation of chemical nocive substances in biological systems.
Mercury is a toxic metal that bioaccumulates in life forms such as fish and then passes to humans, which is a serious threat to health.In conclusion, mercury can accumulate in biological systems and then pass to humans after consumption (e.g., fish consumption).
