b) Identify a dependent variable in the experiments. Identify the reasoning of the scientists when they tested the number of colonies produced by strains C3-PBB and C6-PBB . The scientists also analyzed the number of colonies produced from each of the environmental and clinical isolate strains when the strains were plated on a growth medium lacking the toxic chemical. Justify this analysis.
A dependent variable is the number of colonies produced. The experiment gives a useful insight into the toxicity of the chemicals.
A scientific experiment must always have a dependent and an independent variable. A dependent variable is the variable whose outcome is being determined by manipulating the independent variable which in this case is the presence or absence of the chemicals.
Toxicity of chemical substances is a very important information to scientists as such this experiment is very important because it highlights the toxicity of the chemicals to living things.

When you exhale, what happens in the lungs?
A. Air moves from high pressure (in the lungs) to low pressure (outside)
B. Space in the lungs increases
C. Lung pressure decreases
D. Air moves from low pressure (in the lungs) to high pressure (outside)
Answer:
Conversely, exhalation moves the diaphragm up into the chest cavity and reduces the space in it. This forces the air, which is dense with carbon dioxide at that point, out of the lungs and windpipe. It then exits the body either through the nose or mouth. Usually, this requires no physical effort from the body.

how many body systems are in eating a single bite of turkey? PLSS HELP its duo in abt 6 mins!!
Answer:
There are 4 systems involved in this activity. these systems are: the skeletal, muscular, circulatory and digestive systems.
Explanation:
To eat a single bite of turkey it is necessary that 4 systems come into play and work together for this activity to be possible.
First, it is necessary that the turkey is brought to your mouth through the movement of its members. In that sense, the resqueletico and muscular systems will act because it is through them that the movements of the members are created.
Then you will need to bite the turkey, chew it, moisten it with saliva, swallow it and digest it. This work will be done with the digestive system that will manage all of these activities.
Finally, your body will need to absorb the elements that make up the turkey pedal that you ate and that were rescued by digestion, these elements are nutrients, proteins and others. All will be absorbed through the work of the circulatory system, which through the blood will carry the elements throughout the body.

Answer:
The term amino acid is short for α-amino [alpha-amino] carboxylic acid. Each molecule contains a central carbon (C) atom, called the α-carbon, to which both an amino and a carboxyl group are attached. The remaining two bonds of the α-carbon atom are generally satisfied by a hydrogen (H) atom and the R group.

Answer: # 1: c. #2: d. #3: a
Explanation:
#1 is C. because the equation for cellular respiration is C₆H₁₂O₆
+ 6O2 --> 6H20 + 6CO2 + ATP
This says the reactants (inputs) are oxygen and glucose and the products (outputs) are water, carbon dioxide, and ATP. 1 glucose molecule makes 6 carbon dioxide, so 3 glucose would make 18 carbon dioxide molecules.
#2 is D. because the law of conservation of matter states that matter cannot be created nor destroyed, so the weight before and after cellular respiration would stay the same, as the matter would not change.
#3 is A. because a model would show the exact way the molecules would be arranged, while a formula only tells you how many there are, not the way they would be made up.

If a DNA strand has 23 % guanine before semi conservative replication occurs, what percent Thymine will each new strand have after replication?
Answer:
27%
Explanation:
DNA is a linear molecule composed of four nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T). Chargaff's rules state that adenine (A) always pairs with thymine (T), while guanine (G) always pairs with cytosine(C). In consequence, the amount of G should be equal to the content of C, while the amount of T should be equal to the content of A. In this case, the content of G is 23% and the content of C is also 23%, so the remaining content (A + T) is equal to 54% [100 - (23 + 23) = 54%], thereby content of A is equal to 27% and the content of T is also 27% (27 + 27 = 54%).

In eukaryotes the electron transport chain is composed of a series of electron carriers located in the blank of mitochondrion
Answer:
Facts that is right
Explanation:
In eukaryotes, the electron transport chain is composed of a series of electron carriers located in the inner membrane of the mitochondrion
The electron transport chain is composed of four large, multiprotein complexes. These protein complexes are formed of a series of electron carriers.
These complexes are embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.These transfer electrons from electron donors to electron acceptors via redox reactions and joins this electron transfer with the transfer of protons across a membrane.Thus, in eukaryotes, the electron transport chain is composed of a series of electron carriers located in the inner membrane of the mitochondrion

Answer:
1) Transcription Bubble.
2) Replication Forks
3)
Explanation:
1) The region of opened- up DNA is called a Transcription Bubble. In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complentary RNA transcript.
2) The Replication Forks hold the 2 separated strands of DNA apart, preventing then from assuming their double helix shape... in order to replicate all your DNA its faster to replicate DNA if your doing it in many different areas at the same.
3)Since DNA polymerase requires a free 3` OH group for initiation of synthesis, it can synthesize in only one direction by extending the 3` end of the preexisting nucleotide chain. Hence, DNA polymerase moves along the template strand in a 3`-5` direction, and the daughter strand is formed in a 5`-3` direction.

Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.

Answer: I think Negative?
Explanation:
Describe your diagnosis for the patient. How did the chlorine gas affect concentration difference, diffusion distance, and surface area in the patient’s lungs? Explain how these affected the diffusion rate.
The concentration difference and surface area lead to decrease but the diffusion distance increases due to application of chlorine.
The difference in the concentration of a substance between two regions is known as the concentration gradient.
Surface area is the total area that the surface of the object occupies.
Diffusion rate is defined as the change in the quantity of diffusing molecules inside the cell in a specific period of time.
The chlorine gas greatly affected the concentration difference because it lowers the value. The gas increases the diffusion distance but decreases the surface area of the patient's lungs. The decrease in the concentration difference leads to slower the diffusion rate.
It is because there is less difference in the concentration of both regions i.e. lungs and the surrounding atmosphere and when there is equal amount on both sides the diffusion of gas molecules stopped so we can say that decrease occur in the concentration difference and surface area but increase occur in the diffusion distance

The IQ range that indicates moderate mental *********** is A. 70-79.
What is an IQ?
IQ stands for Intelligence Quotient and is a measure of cognitive abilities and intellectual potential. It is determined through standardized tests that assess various cognitive skills, including problem-solving, memory, and analytical thinking.
The average IQ score is set at 100, with scores ranging from 70 to 130 considered to be within the normal range. Scores below 70 indicate varying degrees of intellectual disability, while scores above 130 suggest above-average intelligence.
While IQ scores can provide insight into a person's cognitive abilities, they do not account for other factors, such as emotional intelligence or creativity, that may contribute to overall success in life. It is essential to recognize that IQ tests have limitations and should not be used to label individuals or limit their potential.
This range is considered to be a mild to moderate intellectual disability, indicating limitations in adaptive functioning and potential need for support in daily life activities.
