In a food chain, concentrations of harmful substances increase in higher trophic levels in a process known as
A. biological magnification.
B. genetic drift.
C. biological succession.
D. pesticide resistance.
The A. Biological magnification is the process which causes toxic substances to increase at each trophic level in a food chain, making apex consumers most at risk.
The term that describes the process whereby toxic substances increase along trophic levels of an ecosystem is biological magnification. This phenomenon occurs when synthetic chemicals, such as pesticides, become more concentrated as they move up the food chain, resulting in higher levels of toxicity for organisms at the top. For instance, when a marsh is sprayed with DDT to control mosquitoes, microscopic aquatic organisms like plankton absorb trace amounts of DDT.
Filter-feeders such as clams and some fish then ingest the plankton, accumulating DDT in higher concentrations. This process continues upwards through the food chain, with each trophic level experiencing a significant increase in the concentration of these harmful substances, often resulting in detrimental effects on apex consumers.

Name two factors that cause a decrease in population size.
Mortality and emigration are the two factors that cause a decrease in population size.
Mortality is defined as the number of deaths in a population over time. When rates of mortality are high, population size might be reduced. Disease, accidents, and natural disasters are all common causes of death.
Emigration is a migration of people away from a country or region. When people emigrate, they are no longer considered a part of the population of the country or territory from where they departed. People may emigrate for a variety of reasons, including political instability, economic opportunities, and war.

Final answer:
A decrease in population size can result from economic and social crises that lead to lower birth rates, as well as high death rates due to health issues. Environmental factors, such as the availability of resources influenced by human activities, like the use of pesticides and habitat destruction, also affect population size.
Explanation:
Two factors that cause a decrease in population size include economic and social crisis, leading to reduced birth rates, and high death rates due to health issues and the collapse of social safety nets. For example, populations decline when birth rates drop during periods of economic hardship as individuals delay or forego having children. Additionally, a rise in mortality, due to factors like alcoholism or heart disease, can lead to a population decrease if the death rate surpasses the birth rate.
Another factor that can decrease population size is environmental resources, which are affected by human activities such as the use of pesticides and habitat destruction. A decline in available resources can lead to increased mortality rates and lower birth rates over time.

Fermentation reactions generally occur under conditions of:
Fermentation reactions occur in anaerobic or low-oxygen environments.
Fermentation generates energy without oxygen, unlike aerobic respiration. Certain microbes and cells can ferment to produce energy under anaerobic settings. Bacteria, yeast, and human cells are included.
When oxygen is scarce, fermentation produces energy. It breaks down organic molecules like glucose without oxidation like aerobic respiration. The process generates ATP (adenosine triphosphate) and numerous end products depending on the organism and fermentation pathway.
Yeast ferments sugar into alcohol and carbon dioxide, and bacteria and muscle cells ferment sugar into lactic acid. These reactions make bread, wine, beer, and yoghurt.

Bradley decides one day to run a marathon without any training. After ten minutes has elapsed and Bradley has run half a mile, he begins to get cramps in his thighs. He is also breathing very rapidly. What is causing the cramps on Bradley's legs?
Answer:
The correct answer is "lactic fermentation".
Explanation:
Lactic fermentation is a type of anaerobic respiration that occurs in muscle cells as a way to produce energy when not enough oxygen reach the cells. This happens when a person is performing anaerobic exercise for a considerable period of time or without proper training, like Bradley that tried to run a marathon without any training. Lactic fermentation produces lactic acid build up on muscles, which is what is causing the cramps on Bradley's legs.

The cactus has a specialized fleshy stem and it's leaves function only for protection. Which plant tissues most likely makes up the stem?
The correct answer is vascular tissues.
Vascular tissues most likely form the stem. The prime vessels observed on the vascular tissue are the phloem and the xylem. These two tissues function as an element for the conduction of nutrients and water within the stem.
The xylem transports some nutrients and water from the roots, while the phloem transports the soluble organic constituents, which were generated at the time of photosynthesis from the leaves.

about one in ____ individuals diagnosed with an eating disorder is male.
Further explanation
During this time, eating disorders are always associated with women. Some of the well-known eating disorders are bulimia and anorexia nervosa. In fact, eating disorders can also be experienced by men, both children and adult men.
Eating disorders in men were first recorded in the 16th century, precisely in 1689. At that time, the doctor from England, Richard Morton, noted two cases of anorexia nervosa in one male patient. Then in 1874, Ernest Charles Lasegue and Sir William Gull made another case report about men with anorexia nervosa.
after these early cases, men with eating disorders were considered "rare" until 1972 when Peter Beaumont and colleagues conducted research on anorexia nervosa in men. But now, a lot of research on the treatment of eating disorders that do not involve male subjects.
the total proportion of men with eating disorders is not known with certainty. Older statistics say 10 percent, but given the reluctance of men with eating disorders to admit that they have the problem, most experts believe the figure is higher.
The National Association for Males with Eating Disorders estimates that 25 to 40 percent of people with eating disorders are men.
Among other eating disorders, men have relatively more representation in the categories of binge-eating disorder and Avoidant Restrictive Food Intake Disorder (ARFID). Statistics show that about 40 percent of people with binge-eating disorders are men.
