1. Discuss at least two attributes of a study that you would look for to determine whether or not it is rigorous.
Answers
Some of the aspects that help you determine whether a study is rigorous are questions and hypotheses that can be answered, adequated method use, and bibliography.
Rigorous is a term that refers to a quality that focuses on accuracy and precision to comply with norms, precepts, and pre-established rules. This term is widely used in science to refer to the precision of a study or investigation.
Therefore, when it is established that a study is rigorous, its attributes must be taken into account, such as:
- Questions and hypotheses that can be answered: This aspect refers to the investigator having the ability to limit his study so that it is appropriate to do so and does not include too much information that makes his study "impossible".
- Adequated methods use: This refers to using the appropriate methods to reach feasible conclusions, for example, methods of observation, deduction, induction, among others.
- Bibliography: This refers to the research or study being supported by reliable sources so that it is as accurate as the information it provides.

Under normal conditions the sympathetic division is usually active in the body resting heart rates are influenced by nor epinephrine the parasympathetic system keeps heart rate lower than the heart would beat on its own. all of the above are true
Answers
Answer:
the parasympathetic system keeps heart rate lower than the heart would beat on its own.
Explanation:
The parasympathetic nervous system (PNS) is one division of the autonomic nervous system. The vagus (parasympathetic) nerves that innervate the heart release acetylcholine in order to slow the heart rate by decreasing the slope of the pacemaker potential. Acetylcholine activates a type of G-coupled protein receptor known as muscarinic receptors, allowing for a parasympathetic reaction in the cardiovascular system (where these receptors are expressed), and thereby decreasing cardiac output by inhibiting heart rate. During rest, PNS predominates and controls the heart rate at a resting rate of 65-80 beats/minute (bpm), if parasympathetic nerves to the heart are cut, then the heart beats at its own rate of about 100 bpm.

The currently accepted model of the cell membrane was discovered by ________ in the year ______
A) Charles Overton, 1895
B) singer and Nicolson, 1972
C) Davison and Danielli, 1970
D) Irving Langmuir, 1917
Answers
Answer: B
Explanation: The currently accepted model of the membrane is the fluid mosaic model. S. J. Singer and G. Nicolson proposed the fluid mosaic model in 1972.
The cell membrane model depicts the arrangement of the biological membrane and its component. The fluid mosaic model was given by Singer and Nicolson in 1972. Thus, option B is correct.
What is the fluid mosaic model?
The fluid mosaic model was discovered by Singer and Nicolson and is a widely accepted model for the structural organization of the plasma membrane and its components. It elucidates the mosaic of plasma components.
The proteins, lipids, and carbohydrates are the main components of the plasma membrane that are arranged and shows the fluid nature of the biological membrane.
Its arrangement and structure allow the semi-permeable nature and its role as the barrier. It shows the membrane is a lipid bilayer that includes the hydrophobic tail and the hydrophilic head.
Therefore, the fluid mosaic model was given by Singer and Nicolson.

Answers
The best way to ensure that results of a study are generalizable to a population is by using a random selection of people in that population
The goal of every research experiment is to obtain results that are generalizable to a whole population.
This is achieved by the method of random selection. In random selection, members of the of the population are selected in such a way that is representative of the entire population. If for instance, I want to study a school having six classes which comprises of boys and girls. There are 700 students in the school and I need only 180 students to participate in a study whose results will be extrapolated to all the 700 students. I can decide to randomly select 15 boys and 15 girls from each class to participate in the study. This is an example of random selection.
In this way, the results obtained from the study is reflective of the whole population even though only a sample of the population actually participated in the study.

What is the frequency of a wave that has a wavelength of .20 m and a speed of 22 m/s
Answers
Answer:
110 Hz
Explanation:
Find the frequency of the wave using the formula, frequency = speed / wavelength.
Plug in the speed and wavelength, and solve:
frequency = speed / wavelength
frequency = 22 / 0.2
frequency = 110
So, the frequency of the wave is 110 Hz
