Why do you think people believe some theories even if they´re not supported by scientific evidence?
Answer:
The correct answer would be
1. to understand and have certainty
2. to have control and sense of security.
3. to maintain positive image of one self
Explanation:
Theories that can not be proved or tested or have no scientific evidence about them should not be consider valid, however, some people believe in these theories.
The reason behind these false believe, according studies could be any of these reasons:
1. to understand and have certainty - to understand and have a explanation to satisfy their curiosity.
2. to have control and sense of security - if there is something bother sense of security of individual or group of people.
3. to maintain positive image of one self - to portray them not responsible for any immoral happening or deeds.
You are interested in how stress affects heart rate in humans. Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate. How could you manipulate this stress?
Answer:
As an example, you are interested in how stress affects heart rate in humans. Your independent variable would be the stress and the dependent variable would be the heart rate. You can directly manipulate stress levels in your human subjects and measure how those stress levels change heart rate.
Explanation:
"Immediately prior to ventricular systole, pressure in the aorta is about" "The Frank-Starling law of the heart states that"
Answer:
80 mm Hg
Explanation:
Immediately prior to ventricular systole, pressure in the aorta is about 80 mm Hg. This can be explained by the Frank-Starling Law which states that the stroke volume of the left ventricle will increase as the left ventricular volume increases due to the myocyte stretch which tends to cause a more forceful systolic contraction. This applies in the case that all of the other factors remain the same during that time.

What section of a lab report should be phrased in an "If (cause), then (effect)" statement?
le
Answer:
The HYPOTHESIS
Explanation:
In an experiment, the formulation of the hypothesis is a critical part of the scientific method. The hypothesis is testable explanation given after making an observation in an experiment. In other words, an hypothesis is a predictive statement given that is subject to testing via experimentation.
The essence of formulating an hypothesis is to relate the effect of a possible solution on an observed problem. The "hypothesis" section of a laboratory report is usually identified by the use of an IF and THEN phrases in the statement. IF represents the cause, while THEN represents the effect. For example, a hypothesis can read; If plants are placed under white light (cause), then they will grow faster in height (effect).
A box is pushed across 10m by a force of 40 N in 10 seconds.calculate the power.
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{40 \: watt}}}}}[/tex]
Explanation:
Given,
Distance ( D ) = 10 m
Force ( F ) = 40 N
Time taken ( T ) = 10 seconds
Calculating the power:
[tex] \boxed{ \sf{power = \frac{work}{time} }}[/tex]
⇒[tex] \sf{power = \frac{force \times distance}{time} }[/tex]
⇒[tex] \sf{power = \frac{40 \times 10}{10} }[/tex]
⇒[tex] \sf{power = \frac{400}{10} }[/tex]
⇒[tex] \sf{power = 40 \: watt}[/tex]
Hope I helped!
Best regards!!

Provided question is incomplete as proper information is not given, however, the complete question is as follows:
Several different kinds of bonds or interactions are involved in generating and maintaining the structure of proteins. List five such bonds or interactions.
Select the five correct answers.
Answer:
The correct answer is:
peptide bond
hydrogen bond
ionic bond
disulfide bond
hydrophobic bond
Explanation:
In protein structure their are different type of bonds present in between different atoms of amino acid to forming or maintaining the protein and its structure. These bonds are as follows:
Peptide bond: These bonds are present in all amino acids, joins monomers in primary structure
Hydrogen (not between R groups): these are bonds present in all amino acids, these bonds are responsible for the secondary structure .
Hydrophobic: leucine could be involved, These type of interactions are responsible for tertiary and Quaternary structure
Ionic: glutamate could be involved in such bond, these are also responsible for the tertiary and Quaternary structure
Disulfide: cysteine could be involved in such bonding, tertiary and Quaternary structure
Where does our energy from from?
An ecologist collected climate data from two locations. The graph shows the monthly average temperatures in the two locations. In Location A, the total yearly precipitation is 273 cm. In Location B, the total yearly precipitation is 11 cm. Whats the answer?
Answer:
More organisms are present on location A.
Explanation:
Due to more yearly precipitation, there is more vegetation present on location A. Due to the presence of this vegetation, more organisms are present because there is more food available for organisms as compared to location B. Due to less precipitation, there is less or no vegetation is present on location B and organisms are present in less number due to harsh environmental conditions and no food availability for organisms.

Answer:
A set of paradigms or views shaped by one's background, culture and education which determine the way an individual or a group evaluate and find solutions to the existing environmental problems.
Explanation:
Environmental value system (EVS) is a view of a subject that transforms the way an individuals or the society thinks, view and evaluate environmental issues.
Their ideas and views is influenced by cultural, economic and socio-political background.

Diagnosis of Gardnerella vaginitis is made by the appearance of _____. anaerobes in a microscope slide clue cells epithelial cells endotoxin
Answer: The correct answer to the question is option B
CLUE CELLS.
Explanation: Gardnerella vaginitis is also known as bacteria vaginosis.
It is a disease of the reproductive system that affects mostly women of child bearing age, bacteria vaginosis occurs when there is a shift or change in the normal balance of bacteria found in the Vagina,this change in bacteria balance results in infection.
Symptoms of includes vaginal itching, abnormal vaginal discharge and odour.
When Gardnerella vaginitis is diagnosed,the following are being noted;
Clue cells; this involve coating vaginal skin cells with bacteria,clue cells are visible on microscopic exam of vaginal fluid.
When vaginal fluid is tested and the PH shows low acidity( a PH greater than 4.5 precisely).
(WHIFF TEST)When there is a fishy odour upon combination of vaginal discharge with a drop of magnesium hydroxide. A glass slide is used for this test.
