Making concepts personally relevant to an individual helps to learn them. Below are several concepts from your reading. For each concept, give one example from your daily life and explain why your example fits the concept listed. Each concept should be a minimum of 50 words with citations to support your examples. List all references at the end of the list in Example:Sensation – I like listening to my music before going to sleep, but if my parents hear my music after 10 pm, I get in trouble. If my music is below their absolute threshold, then I won’t get in trouble, because they won’t hear it. It is really hard to keep it below their absolute thresholds because it seems that even the faintest amount of sound coming from my room is detectable. In this example, the absolute threshold is the lowest amount of volume that they can detect up to 50% of the time (Grison, Absolute Threshold Can ya make a long sentence of absolute threshold?
An absolute threshold is the smallest level of stimulus that can be detected, usually defined as at least half the time. The term is often used in neuroscience and experimental research and can be applied to any stimulus that can be detected by the human senses including sound, touch, taste, sight, and smell.
For example, in an experiment on sound detention, researchers may present a sound with varying levels of volume. The smallest level that a participant is able to hear is the absolute threshold.
However, it is important to note that at such low levels, participants may only detect the stimulus part of the time. Because of this, the absolute threshold is usually defined as the smallest level of a stimulus that a person is able to detect 50% of the time.
For hearing, the absolute threshold refers to the smallest level of a tone that can be detected by normal hearing when there are no other interfering sounds present. An example of this might be measured at what levels participants can detect the ticking sound of a clock.
Young children generally have a lower absolute threshold for sounds since the ability to detect sounds at the lowest and highest ranges tends to decrease with age.
For vision, the absolute threshold refers to the smallest level of light that a participant can detect. Determining the absolute threshold for vision might involve measuring the distance at which a participant can detect the presence of a candle flame in the dark.
For odors, the absolute threshold involves the smallest concentration that a participant is able to smell. An example of this would be to measure the smallest amount of perfume that a subject is able to smell in a large room.
The amount of force required for you to detect the feeling of a feather lightly brushing your arm is an example of the absolute threshold for touch. When it comes to touch, the level of stimulation required to detect the stimulus can vary dramatically depending upon the part of the body that is being touched.

During plant cell replication the division of the cytoplasm is called?A. CyttohydolsisB. Cytokinesis Plasmosis D. Cytoplasmosis
After the cells perform all the previous processes of the cell cycle, at the end of them, it results in two daughter cells for mitosis and meiosis I, and four daughter cells for meiosis II. This is accomplished because the cell uses proteins such as actin and myosin to enclose the resulting nuclei and the different organelles of each cell. We can say then that the correct answer is the second one: cytokinesis, and this can be seen with a little more detail in the picture below at the right part of it.
What is the dependent variable in the following scenario: A professor wonders if her students will improve their test scores if they study in the same room where they will test. She divides her class in half and asks them to all study for one hour the night before the test. Half of the class studies for one hour in the classroom where the test will take place. The other half of the class studies wherever they want. She compares their grades on the test to see which group did better.
In any experiment, you can define the independent variable (or variables) as any factor that is considered to affect directly the object of study, and the dependent variable is the effect observed.
In this scenario, the professor thinks that the place where the students study affects the result of their exams.
Out of these two variables "the result in the exam" is the observed effect, and thus, the dependent variable and the "location where the student studies" is the factor that affects it, therefore it is the independent variable.

In humans, the allele for a widow's peak is dominant to the allele for a straight hairline. In a family with three children, two of the children have a straight hairline and one child has a widow's peak. Which of the following is possible? (please i will give brainliest)
Both parents are heterozygous.
Both parents are homozygous for a widow's peak.
Both parents are homozygous for a straight hairline.
One parent is homozygous for a straight hairline, and the other is heterozygous.
The correct answer is that one of the parents is homozygous while the other one is heterozygous.
Widow's peak is a dominant trait which is observed even when a single dominant allele responsible for this characteristic is present in an individual. A widow's peak is used to refer to the hairline of a person which is shaped like the letter 'V' progressing downwards towards the central portion of the forehead.
However, the allele for straight hairline is recessive which means that in the given case one parent must be homozygous, i.e. contain similar alleles (recessive), while the other one with a widow's peak is heterozygous.

short segments of newly synthesized dna are joined into a continuous strand by _____.
Short segments of newly synthesized DNA are joined into a continuous strand by DNA Ligase.
What is DNA ligase?DNA ligase is a group of enzymes that catalyze the binding of two molecules, which are DNA; synthetase.
During DNA replication, DNA molecules are synthesized on the leading strand continuously, whereas on the lagging strand, DNA is synthesized in short stretches.
These short stretches of DNA are called okazaki fragments and are later joined together by an enzyme called DNA ligase.
Therefore, DNA ligase is responsible for joining newly synthesized DNA molecules.

Discuss assumptions about men and women, class status, religion, and race.
Social inequality is typically thought of as the absence of result equality, but it may also be thought of as the absence of opportunity equality. Race, gender, class, and religion are interrelated identity characteristics that have an impact on many facets of life in the United States.
These social institutions might become more important at any point in a person's life, and everyone is affected by them.
Gender, on the other hand, is an identity that is independent of a person's biological sex. Girls and women are frequently expected to behave nicely, dress in stereotypically feminine ways, and provide for others. Typically, men are expected to be strong, brave, and competitive.
In society, class refers to the division of people into groups based on their socioeconomic circumstances. Based on variables like wealth, occupation, or education, the grouping is stratified. Therefore, it stands to reason that the higher classes are more powerful and influential than the lower classes.
Religion supports and encourages social conflict and inequity. It causes animosity and violence caused by religious differences and aids in persuading the impoverished to accept their position in life.
The shared and hereditary physical characteristics of a group are typically used to identify a person's race, making the definition of race complex.
As a result, it is clear that race, gender, class, and religion are interconnected identity qualities that influence many aspects of American life.

How come the vertebrae protects the spinal but the PNS has no bone protection?
The Central Nervous System (CNS) is of vital importance, meaning that any small trauma that it may suffer can represent a death risk for the individual. This lead natural selection to cause the organisms to develop a strong protection against those traumas. The Peripheral Nervous System (PNS) is of monumental importance, but the traumas suffered has local impact only. The PNS is also spreaded through the entire body, getting to the tip of our toes and fingers. Therefore, its evolutionary development didn't involve the need of having such a strong protection, and that would have been really difficult as the PNS is so widely spreaded throughout the body.

Describe the structure of the endoplasmic reticulum.
Endoplasmic reticulum is a membrane system forming a series of sacs in eukaryotic cells. It has many functions, including the synthesis and transport of proteins. There are two types of endoplasmic reticulum with different structures, as follows:
1) Rough endoplasmic reticulum - its sacs are convoluted but flat, contiguous with the nuclear membrane. Its outer surface is studded with ribosomes, which gives it the rough appearance.
2) Smooth endoplasmic reticulum - its sacs are tube-like structures and they are located near the cell periphery. Sometimes these tubules branch, forming a reticular network wit.
