Hair analysis may be used to determine all of the following except the presence of heavy metals. Thus, option C is correct.
What is metal?A metal has been defined as a material that has to be prepared freshly and polished and fractured that shows that a lustrous look or appearance and it conducts the electricity as well as heat well relatively. The main nature of metal has that they are totally malleable and ductile and these are the properties of matter which is due to metallic bond which lies in between the atoms or the molecules present in the metal.
There are several properties of metal and these properties are the metals have high point of melting, and the metals are good conductor of electricity, as well as they are good conductors of heat also. The metals consist high density and they are malleable and ductile in the nature.

Match the method of predator management to the challenges It faces. 1. use of firearms considered inhumane 2. use of poisons revised laws 3. use of traps inefficient and dangerous
Answer:
question
Explanation:
did you ever figure out what the answer was? please
Answer:
use of firearms- revised laws
use of posions -inefficient and dangerous
use fo traps- considered inhumane
Explanation:
Option 1 faces a challenge of revised laws. Although use of firearms was once a popular method of control, changes to laws, in particular those pertaining to wolves, have affected the issue. Option 2 faces a challenge of being inefficient and dangerous. Poison is illegal, largely because it is an inefficient practice that can be dangerous to both cattle and nonpredatory wild animals. Option 3 faces a challenge of being considered inhumane. The use of traps is an indiscriminate tool, like poison, often trapping the calves they are intended to protect.

Explanation:
Bacterial disease is caused by the multiplication of bacteria in a patient. How do pathogenic bacteria harm a patient?
Answer:
Host Susceptibility
Resistance to bacterial infections is enhanced by phagocytic cells and an intact immune system. Initial resistance is due to nonspecific mechanisms. Specific immunity develops over time. Susceptibility to some infections is higher in the very young and the very old and in immunosuppressed patients.
Bacterial Infectivity
Bacterial infectivity results from a disturbance in the balance between bacterial virulence and host resistance. The “objective” of bacteria is to multiply rather than to cause disease; it is in the best interest of the bacteria not to kill the host.
Host Resistance
Numerous physical and chemical attributes of the host protect against bacterial infection. These defenses include the antibacterial factors in secretions covering mucosal surfaces and rapid rate of replacement of skin and mucosal epithelial cells. Once the surface of the body is penetrated, bacteria encounter an environment virtually devoid of free iron needed for growth, which requires many of them to scavenge for this essential element. Bacteria invading tissues encounter phagocytic cells that recognize them as foreign, and through a complex signaling mechanism involving interleukins, eicosanoids, and complement, mediate an inflammatory response in which many lymphoid cells participate.
Genetic and Molecular Basis for Virulence
Bacterial virulence factors may be encoded on chromosomal, plasmid, transposon, or temperate bacteriophage DNA; virulence factor genes on transposons or temperate bacteriophage DNA may integrate into the bacterial chromosome.
Host-mediated Pathogenesis
In certain infections (e.g., tuberculosis), tissue damage results from the toxic mediators released by lymphoid cells rather than from bacterial toxins.
Intracellular Growth
Some bacteria (e.g., Rickettsia species) can grow only within eukaryotic cells, whereas others (e.g., Salmonella species) invade cells but do not require them for growth. Most pathogenic bacteria multiply in tissue fluids and not in host cells.
Virulence Factors
Virulence factors help bacteria to (1) invade the host, (2) cause disease, and (3) evade host defenses. The following are types of virulence factors:
Adherence Factors: Many pathogenic bacteria colonize mucosal sites by using pili (fimbriae) to adhere to cells.
Invasion Factors: Surface components that allow the bacterium to invade host cells can be encoded on plasmids, but more often are on the chromosome.
Capsules: Many bacteria are surrounded by capsules that protect them from opsonization and phagocytosis.
Endotoxins: The lipopolysaccharide endotoxins on Gram-negative bacteria cause fever, changes in blood pressure, inflammation, lethal shock, and many other toxic events.
Exotoxins: Exotoxins include several types of protein toxins and enzymes produced and/or secreted from pathogenic bacteria. Major categories include cytotoxins, neurotoxins, and enterotoxins.
Siderophores: Siderophores are iron-binding factors that allow some bacteria to compete with the host for iron, which is bound to hemoglobin, transferrin, and lactoferrin.

What is Anaerobic respiration?
Answer:
"Anaerobic respiration is the process of creating energy without the presence of oxygen. Sometimes the body can't supply the muscles with the oxygen it needs to create energy – such as in a sprinting situation."
I hope this helped!
Answer:
The release of a relatively small amount of energy by the breakdown of food substances in the absence of oxygen. Glucose is broken down to release energy in the absence of oxygen, forming lactic acid in muscle tissue, or alcohol plus carbon dioxide in yeast and plants.

Explanation:
Why is it important to understand challenges in a species environment in order to understand the species evolution? Relate your answer to what Darwin referred to as "the struggle for survival"
Answer:
The Struggle for Survival refers to the fight between organisms to survive by having access to the increasingly scarce resources in the environment brought upon by population increase.
Darwin believed that evolution was brought about by external pressures arising from this struggle for survival as species would have to adapt to the unique challenges in their environment to be able to better access resources.
This is why one must understand the challenges in an environment to understand why species in that environment evolved the way they did.

Define homeostasis and explain why it is important.
Homeostasis is the ability of an organism or system to maintain a stable internal environment despite changes in the external environment. The term was coined by Walter Bradford Cannon in 1930 and comes from the Greek words "homeo," meaning "similar," and "stasis," meaning "standing still."
Homeostasis applies to the body's physiological processes, such as metabolism, temperature regulation, fluid balance, and hormone secretion. These processes involve a series of feedback mechanisms that sense changes in the body and trigger responses to restore balance. For example, when the body's temperature rises above a certain level, thermoreceptors in the skin and hypothalamus signal the sweat glands to produce sweat and the blood vessels to dilate, which helps to dissipate heat and bring down the temperature.
Homeostasis also applies to psychological processes, such as mood, stress, and arousal. These processes involve the brain's regulatory systems, such as the limbic system, the autonomic nervous system, and the endocrine system. These systems work in tandem to respond to internal and external stimuli, and regulate emotions, instinctual drives, and cognitive processes.
The concept of homeostasis is important in understanding health and disease. When homeostasis is disrupted, the body or mind may experience dysfunction, disease, or pathology. For example, chronic stress can lead to an overactive HPA axis and the release of cortisol, which can suppress the immune system and lead to inflammation and disease. Diabetes is also a condition where the body's homeostasis is disrupted, resulting in high blood glucose levels and impaired glucose metabolism.
