Answer:
preparedness.
Preparedness is the tendency to learn some associations more easily, quickly and permanently than others.
<span>A sample that is large and randomly selected<span> is most likely to yield generalizable results. A large and randomly selected sample shows the real diversity of the population with little relevance of bias within the findings and produces generalizable results. Also, the results from the sample gives accurate representation of the larger population and are easy to use.</span></span>
Answer:
mtDNA is used, consider forensic laboratories to characterize bone remains and identify individuals who have other evidence
The disadvantage of using mtDNA in relation to nuclear DNA is that it does not identify individuals unambiguously, it only detects relationships between groups of individuals
Answer:
The receptor senses changes in the environment and responds by sending information (input) to the control center along the ascending pathway. The control center analyzes the input, determines the appropriate response, and activates the effector by sending information along the descending pathway. When the response causes the initial stimulus to decline, the homeostatic mechanism is referred to as a negative feedback mechanism. When the response enhances the initial stimulus, the mechanism is called a positive feedback mechanism. Negative feedback, mechanisms are much more common in the body.
Explanation:
Homeostasis is the adaptation of living organisms or systems to new conditions in the environment by auto-regulation. Through this mechanism, an equilibrium state can be maintained in spite of any changes. This adjustment in the physiological system is called <em>homeostatic regulation</em> and it is composed of three parts: the receptor, the control center, and the effector.
The receptors receive information from the environment about something changing and transmit that information to the central nervous system (control center). This pathway is defined as the ascending pathway. Information is processed in the control center which handles many sensory signals, evaluates them, compares them and uses them for decision making. After that, an efferent neuron is stimulated to carry information from the central nervous system to the effector cells of the target organ. The effector may be muscle or glandular tissue. This pathway is defined as the descending pathway. Finally, the target organ responds.
There is negative feedback when the response declines the initial stimulus, which is the <u>most common mechanism</u> in the body. There is positive feedback when the response enhances the initial stimulus, which might be very nocive to the organism.
Answer:
The correct answer is "Catalase".
Explanation:
Catalase is an enzyme that is found in practically all living beings for their important function of catalyzing the reaction of decomposition of hydrogen peroxide to water and oxygen. Catalase is primarily found in organelles involved in respiration and photorespiration, such as mitochondrias and peroxisomes. If catalases are found in rough ER microsomes it would indicate that rough ER has been contaminated with another organelle, such as mitochondrias and peroxisomes.
