Answer:
Genetic drift is the change or mutation in the gene pool over generations. It can take several generations for a genetic drift to take place in a community. But if the population of that generation is smaller, there are higher chances that the genetic drift would occur over the next very generations. Any mutilations that disrupts the natural course of genetic transfer can cause genetic drift to take place in those species.
Final answer:
Genetic drift is a change in allele frequencies due to chance events in small populations, where a few individuals' genetic contributions can significantly impact the gene pool. The smaller the population, the greater the influence of genetic drift.
Explanation:
Understanding Genetic Drift
Genetic drift occurs due to random changes in allele frequencies within a small population from one generation to the next, and it is one of the evolutionary forces. In small populations, a few individuals that reproduce can cause allele frequencies to change just by chance, in a way that may not be reflective of the parent population's allele frequencies. This is analogous to how the composition of Halloween candy in a bucket might be influenced by random chance, based on what types of candy people are handing out. The smaller the population, the greater the impact of genetic drift because each individual's genetic contribution represents a larger portion of the population's gene pool. This is why genetic drift increases its effect as the population size decreases.
In contrast, in larger populations, the removal or addition of a few individuals has minimal impact on the overall allele frequencies due to the law of large numbers. However, in early human evolution, smaller populations meant that genetic drift may have played a substantial role in shaping genetic variation.
Why material removal processes (milling, turning, etc.) are used as secondary process after a primary process (casting, forging, etc.)?
Select one:
a. to reduce material waste
b. to improve the strength of a part
c. to reduce the weight of a part
d. all of the above
Answer:
a. to reduce material waste
Explanation:
This just begs the question, "what is the difference between forming and machining?"
Forming involves changing the shape of the material by permanent plastic deformation. This is the primary process that involves casting and forging of material. The advantages of forming processes include no wastage of the raw material, better mechanical properties of the product and faster production rate. Machining is the process of removing the material in the form of chips by means of a wedge shaped tool(the secondary process). Milling and turning are used as final stage procedures to produce desired final shape of material.

A correlation coefficient is a number from 1 to 1 that indicates the strength and direction of the relationship between variables The correlation coefficient is usually represented by the letter r The closer the number is to 1 be it negative or positive the ____________.
Answer:
Explanation:
The closer the value of r is to 1 or -1, the stronger the relationship between the two variables plotted on the graph either positive or negative. Where 1 or -1 means there is perfect linear relationship between the variables also important to note is that strong correlation does not signify that one variable cause the other.
The correlation coefficient, or 'r', measures the strength and direction of a relationship between two variables. The value of 'r' is between -1 and 1. The closer 'r' is to either -1 or 1, the stronger the correlation.
Explanation:In the field of statistics, a correlation coefficient, symbolized by 'r', represents the strength and direction of the relationship between two variables. The value of the correlation coefficient ranges from -1 to 1. The positive or negative sign indicates the direction (positive correlation or negative correlation) of the relationship. The closer the correlation coefficient 'r' is to -1 or 1, the stronger the correlation is between the variables being analyzed. For instance, an 'r' value of 0.8 indicates a strong positive correlation while an 'r' value of -0.8 indicates a strong negative correlation. Importantly, an 'r' of 0 would imply no correlation at all between the variables.

Researchers use biological, psychological, and social-cultural levels of analysis to understand eating disorders the social-cultiral level of analysis is especially likely to emphasice that eating disorders are influenced by:_______.a) the sight and smell of food.b) mass media standards of appearance.c) bouts of depression and anxiety.d) stress and mood.
Final answer:
Eating disorders are significantly influenced by social-cultural factors, primarily mass media standards of appearance and the cultural idealization of thinness, particularly impacting women.
Explanation:
Within the social-cultural level of analysis, eating disorders are influenced significantly by societal norms and values, particularly around body image and beauty standards. Specifically, the cultural idealization of thinness and mass media standards of appearance can be major contributing factors to the development of conditions such as anorexia nervosa and bulimia nervosa. These societal pressures particularly affect women due to the emphasis on slenderness as a beauty ideal. Such cultural norms perpetuate the occurrence of eating disorders, and even if individuals recover, new cases may emerge unless there is a change in these societal standards.

According to Piaget, ___________ is the process by which people understand an experience in terms of their current stage of cognitive development and way of thinking. Group of answer choices
The correct answer is assimilation
Explanation: Assimilation is taken as the subject's ability to incorporate a new object or idea into a scheme, that is, to structures already built or already consolidated by the child.
In Piaget's theory of cognitive development, assimilation refers to the process of understanding new experiences in terms of our existing cognitive structures. An example is a child initially categorizing a flying squirrel as a bird due to its ability to fly. As the child learns more, they adjust this categorization, a process known as accommodation.
Explanation:According to Jean Piaget, a Swiss psychologist known for his work on child development, the process by which people understand an experience in terms of their current stage of cognitive development and way of thinking is referred to as assimilation.
This concept is a fundamental part of Piaget's theory of cognitive development. For example, if a child sees a flying squirrel, they might categorize it as a bird because it fits their current understanding of the category of creatures that fly. Over time, as they gather new information, they adjust or accommodate their understanding (a process known as accommodation) to efficiently classify the world around them.

-A component in the differences between individuals in the risk of disease can be explained by events that are not epidemiologically manageable, including events that extend through the subcellular and cellular level, to casual events.
-At the population level, a large proportion of cases of disease is attributable to influences that only represent a small proportion of inter-individual variation in risk.
-Epidemiology is a discipline at the group level, often related to the incidence rather than to particular incidents. Some ecological studies address the causes of population disease, but are subject to many well-known biases and objective evidence tests in different study designs.
-Genetic variants are supported by individuals but must be analyzed at the group level.
-The important stochastic element in the cause of illness and the response to the specific treatment that medicine should be personalized. In fact, the transition from personalized to stratified medicine reflects the fact that, in most situations, data at the group level instead of individual data provide decisions for treatment, and affect the basis for evidence based medicine.
Explanation:
Dr. Kang, a cognitive psychologist, conducts an experiment examining the effect of emotion on memory. He provides lists of 15 words to two groups of participants at his university. He puts the names of all the participants in a hat. The first 20 names he assigns to Group A and the last 20 he assigns to Group B. Group A is given a list of words that are very emotional in content (e.g., passion, murder). Group B is given a list of words that are neutral in content (e.g., houseplant, desk). He then measures how many words each group is able to remember after being distracted for 5 minutes by watching a video about the history of the university. He finds that Group A remembers 15% more words than Group B.
Dr. Kang sends his study to a journal to be published. One of the peer reviewers questions the way Dr. Kang manipulated emotion, arguing that being exposed to emotional words does not make one emotional. The reviewer is questioning which of the following?
a) the statistical validity of the study
b) the internal validity of the study
c) the external validity of the study
d) the construct validity of the study
Answer:
d) the construct validity of the study
Explanation:
Construct validity relates to the extent in which assumptions from the operationalizations in your analysis to the conceptual frameworks on which those operationalizations were centered may genuinely be produced.
Construct validity is related to generalization, as is external validity.
