Explanation:
When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because:_____________. 1. glycolysis does not occur to significant extent under aerobic conditions. 2. muscle is metabolically less active under aerobic than anaerobic conditions. 3. the lactic acid generated is rapidly incorporated into lipids under aerobic conditions. 4. under aerobic conditions in muscle, the major energy-yielding pathway is the pentose phosphate pathway, which does not produce lactate. 5. under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
Answer:
5. under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
Explanation:
The contraction of muscles occurs in the presence of Adenosine Triphosphate (ATP) because ATP supplies the muscles with the energy they require for contraction.
Muscles can undergo contraction Aerobically ( in the presence of oxygen) or Anaerobically ( in the absence of oxygen).
When a muscle is stimulated to contract aerobically, less lactic acid is formed than when it contracts anaerobically because under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.
The branch of science which deals with a living being is called biology.
The correct answer is E.
The process of breakdown of the glucose molecule into pyruvic acid is called glycolysis. The process of glycolysis is done under the aerobic reaction. The reaction which took place in presence of air is called aerobic reaction.
In this process, Glucose is completely digested into carbon dioxide, water, and energy. Hence, the lactic acid is not formed.
The lactic acid is formed due to a lack of oxygen and leads to incomplete oxidation.
Hence, the correct answer is E that is under aerobic conditions most of the pyruvate generated as a result of glycolysis is oxidized by the citric acid cycle rather than reduced to lactate.

Which observation about the phosphorus tracer supported the researchers' conclusion that DNA, and not proteins, transmits genetic information? A. It was in the supernatant only. B. It was in the pellet only. C. It was in both the pellet and the supernatant. D. It was in neither the pellet nor the supernatant.
Answer:
Hershey and Chase demonstrated that genetic material is contained in the DNA molecule. By using bacteriophages they observed that DNA, but not proteins, contains the genetic material. These researchers tagged DNA with radioactive phosphorus and then separated bacteria and protein phages by centrifugation, observing that bacterial pellet was radioactive
The radioactive phosphorus tracer was found only in the pellet (option B), indicating that DNA transmits genetic information.
Explanation:The observation that supports the researchers' conclusion that DNA, and not proteins, transmits genetic information is that the radioactive phosphorus tracer was found only in the pellet, which contained the heavier bacterial cells, and not in the supernatant.
This indicates that the genetic material, which carries information to produce more phage particles, is present in the pellet along with the bacterial cells. Since phosphorus is found in DNA but not proteins, the presence of the radioactive phosphorus in the pellet confirms that DNA is indeed the genetic material.
Kendra often has her hair in her hands and pulls at it. When she is nervous, she tends to pull some of it out, which helps her feel better. Most of the time she does not even realize she is doing this. Which diagnosis would Kendra likely receive?
True / False.
Answer:
The correct answer is trichotillomania.
Explanation:
A hair-pulling disorder also termed as trichotillomania refers to a mental condition that comes under Obsessive-Compulsive and associated disorders. The person suffering from the condition has an irresistible desire to pull hair from different parts of the body like eyebrows, scalp, and eyelids.
The condition results in partial or complete removal of the eyelashes and eyebrows, while if one pulls hair from the scalp it can lead to different degrees of hair loss patches. The condition often interferes with the occupational and social functioning of the individual.

D. Stretch marks
Answer:
A. Striations
Explanation:
Final answer:
A. Striations are grooves or scratches in rocks caused by glaciers. They provide evidence for the direction and force of past glacial movements and are formed through glacial erosion processes like abrasion.
Explanation:
The term that means scratches in rocks caused by glaciers is Striations. These striations, or glacial striae, are lines or grooves cut into bedrock by debris that is carried along the base of a glacier. Evidence of this geological process includes not only the striations themselves but also rock flour, which is finely ground rock produced by glacial abrasion. Glacial striations are a key indicator of past glacial movement and can be found at various scales, from microscopic to several meters in depth and length. They offer clues indicating the direction of ice flow and can be used alongside other features, such as moraines and drumlins, to understand glacial processes.

According to the oxygen-hemoglobin dissociation curve, PO2 in the lungs of 100 mm Hg results in Hb being 98% saturated. At high altitude, there is less O2. At a PO2 in the lungs of 80 mm Hg, Hb would be ________ saturated. According to the oxygen-hemoglobin dissociation curve, PO2 in the lungs of 100 mm Hg results in Hb being 98% saturated. At high altitude, there is less O2. At a PO2 in the lungs of 80 mm Hg, Hb would be ________ saturated. 95% 100% less than 50% 98%
Answer:
95%.
Explanation:
Oxygen-hemoglobin dissociation curve:
Oxygen-hemoglobin dissociation curve is basically a sigmoid curve which relates between the saturation of oxygen (SO2) and partial pressure of oxygen in blood (PO2). It shows the affinity of oxygen with hemoglobin at different temperature and other factors. In the oxygen-hemoglobin dissociation curve; saturated oxygen is ploted on verticle axis and partial pressure of oxygen in mmHg on the horizontal axis.
Here in the above scenario at the high altitude oxygen is less and at 80 mmHg, Hb would be 95% saturated.

When the diaphragm and external intercostal muscles contract, it
Answer:
The correct answer is: lets the air get inside the lungs.
Explanation:
The process of ventilation, or breathing, consists of two parts: inhaling and exhaling.
Inhaling is the name of the process that is responsible for the air entering the body by the respiratory tract. Exhaling is the opposite, it lets the air out. Both are equally important since they allow the gas exchange necessary for the oxygenation of the blood.
When inhaling, the diaphragm and the external intercostal muscles contract. This pulls the ribcage upwards and outwards, which increases lung volume while decreasing the air pressure inside.
Answer:
These are the mechanism of inspiration which increases the capacity of the thoracic cavity, for maximum volume of air to be inhaled during inspiration.
The contraction makes the diaphragm to move towards the abdominal cavity inferiorily creating the space for the distention of lungs during filling with air. When the external inter coastal muscles contracts, the rib cage is pushed upwards and outwards with the sternum remain fixed. This causes expansion of the rib-cage, with further widening of the thoracic cavity for maximum lung capacity.
Explanation:
Which muscles is involved in normal quiet inspiration?
Answer:
The muscles that contribute to quiet breathing are the external intercostal muscles and the diaphragm.
Explanation: When drawing breath, the external intercostal muscles and diaphragm contract simultaneously.

A botanist created a linear model to predict plant height from soil acidity (pH level) for a certain type of plant. The slope of the model was 2.5 centimeters per pH level, the standard deviation of the sample of plant heights was 4 centimeters, and the standard deviation of the soil acidity was 1 pH level. What is the value of the correlation coefficient?
Answer:
0.625
Explanation:
The slope (m) of a linear regression line is ...
[tex]m=r_{xy}\cdot\dfrac{s_y}{s_x}[/tex]
Then we have ...
[tex]2.5=r_{xy}\cdot\dfrac{4}{1}\\\\\dfrac{2.5}{4}=r_{xy}=0.625[/tex]
The value of the correlation coefficient is 0.625.
Here, we are required to find the value of the correlation coefficient given the slope of the regression model and the standard deviation of the dependent and independent variables.
The value of the correlation coefficient is 0.625
and it is dimensionless.
The relationship between the slope of a regression model and the correlation coefficient is given by;
m = r (Sy/Sx)
where
m= slope of the regression model = 2.5cm/pH.r = the correlation coefficient = ?Sy = The standard deviation of the dependent variable i.e Plant height = 4cmSx = The standard deviation of the independent variable i.e soil acidity(pH level) = 1pHTherefore;
2.5 = r × (4/1)
r = 2.5/4
r = 0.625
P.S: It is important to know that the correlation coefficient is a dimensionless parameter.
