Answer:
Trachea: It is the wind pipe — making it a part of the respiratory system
Esophagus: It is the food pipe — making it a part of the digestive system
Trachea: It is shorter, 10–11 centimeters. It connects upper airway to the lungs
Esophagus: It is longer, 25 centimeters. It connects mouth to the stomach
Trachea: It is cartilaginous, made of C-shaped semicircular cartilages. They give it structural stability and prevents it from collapsing
Esophagus: It is muscular. It contracts in a wave-like motion through it’s length to propel food from mouth to stomach a.k.a swallowing
Trachea: It’s opening is protected by Epiglottis, a flap like structure, to prevent food from accidental entering the air passage. It prevents choking
Esophagus: It’s opening is protected by two sphincters. They are muscular rings that constrict to close the esophagus off when food is not being swallowed.
Trachea: It has 2 portions — cervical and thoracic i.e. neck and chest portions.
Esophagus: It has 3 portions — cervical, thoracic and abdominal i.e. neck, chest and stomach portions.

A microbiologist is conducting a research project on chemolithoautotrophs. This means that the investigator is examining certain aspects of a bacterium that is a purple nonsulfur bacteria which depends on light. uses light as its energy source and carbon for organic compounds. can oxidize inorganic molecules such as ammonia and sulfur for energy. can use the energy from sunlight to build organic molecules from carbon dioxide. obtains carbon from organic molecules.
Answer:
uses light as its energy source and carbon for organic compounds.
Explanation:
The purple non-sulfur bacteria which depends on light produces organic food just like plants through the process of photosynthesis. The purple non-sulfur bacteria uses carbondioxide and water with sunlight produces oxygen and glucose which is an organic compound. So that's why purple non-sulfur bacteria is also known as phototrophic means organism that produces their own food through photosynthesis.
A distribution of class scores on a test is approximately normal with a mean of 75 and a
standard deviation of 8. Edna scores an 85%. Does her score place her in the top 10% of
this class?
O A. No, 10.6% of the class scored above her test score
B. Yes, 10.6% of the class scored above her test score
C. No, she scored better than 10.6% of her classmates
D. Yes, less than 10% of the class scored better than her test score
Answer:
O A. No, 10.6% of the class scored above her test score
Explanation:
Using the standard normal distribution (Z score) to solve this problem. The formula is as follows:
Z = x - μ/σ
Where;
σ = standard deviation
μ = mean score
x = Edna's score
According to the information given in this question:
σ = 8
μ = 75%
x = 85%
Z = 85 - 75/8
Z = 10/8
Z = 1.25
Using the table of normal distribution probabilities, we check for Z score of 1.2 under 5 = 0.8944
This means that Edna's percentage score is 89.44%. Hence, (100 - 89.44) = 10.56% is above Edna's score in the class
Approximately, 10.6% of the class scored above Edna's test score, meaning that she is not among the top 10% of her class.

Answer:
100% of children will have a double heterozygous genotype (EeWw)
Explanation:
A homo-zygous individual is an individual that has two dominant alleles or two recessive alleles for a given gene/locus. A dihybrid cross, also known as Mendelian dihybrid cross, refers to a type of cross in which both parents differ in two observed phenotypic traits which are controlled by two distinct non-linked genes. When both parents are inversely homo-zygous for both genes as in this case (i.e., one parent is homo-zygous dominant for the first gene and homo-zygous recessive for the second gene, while the other parent is homo-zygous recessive for the first gene and homo-zygous dominant for the other), all the F1 will be heterozygous, i.e., all F1 individuals will have the EeWw genotype because each parent can produce only one type of gamete (either Ew or eW). If both genes are subject to complete dominance, then the expected phenotypic ratio of the F2 obtained by crossing double heterozygous individuals will be 9:3:3:1, i.e., 9/16 individuals will have the dominant phenotype for both traits (in this case E_W_ genotype), 3/16 individuals will have the dominant phenotype for the first trait (in this case, dominant earlobe E_ww genotype), 3/16 individuals will have the dominant phenotype for the second trait (in this case, dominant hairline eeW_ genotype), and 1/16 will have the recessive phenotype for both traits (in this case, double recessive eeww genotype).
Imagine a continuation of the experiment described above. How might NS3/4A expression impact Sendai virus replication, as measured by the amount of virus produced by the different cells? a. Cells expressing NS3/4A will produce more Sendai virus than cells that do not express NS3/4A. b. Cells expressing NS3/4A will produce less Sendai virus than cells that do not express NS3/4A. c. The two types of cells will produce roughly equal amounts of Sendai virus.
Answer:
The correct answer is - a. Cells expressing more NS3/4a will produce more Sendai virus than cells that do not express NS3/4a.
Explanation:
NS3/4a is a multiprotein serine protease that is a non-covalent heterodimer consisting of a catalytic subunit protein. This heterodimer has an N-terminal one-third of NS3 protein and at an activating cofactor (NS4A) protein.
It acts as an antagonist for cytokine promoters. Thus in the absence of cytokines or reduced levels of cytokines due to inactive promoters) the expression of the virus would increase.

Every day we make choices that can potentially affect our environment. For example, we may toss a plastic drink bottle into the nearby trash because it’s more convenient than walking all the way to the recycling bin. Think about three choices you made this week that could have affected the environment. Did your choices have a positive or a negative effect on the environment? Explain your reasoning.
The three choices that could have affected the environment are as follows:
Utilization of plastic to make it easy for carrying objects.Plants trees in order to build a green environment. Overdependency on vehicles rather bicycles and pedestrians. What is Environment?The environment may be defined as anything which is present in the surroundings of living organisms. This environment basically has two types of factors biotic and abiotic factors.
In the above three choices, building a green environment has a positive effect on the environment. It may also affect living organisms positively. While the rest of the two may stimulate a negative impact on the environment by increasing the levels of carbon dioxide by liberating emission and non-biodegradable plastics.
Therefore, the three choices that could have affected the environment are well mentioned above.

Risk assessment is often used to set “acceptable” levels of toxins for the environment. Propose a concern people may have about using risk assessment in this way.
The concern about risk assessment of acceptable levels of toxins can be a failure to use appropriate risk metrics, incorrect measuring of known risk, failure to take known risks into concern, or failure in risk communication or risk monitoring.
What is meant by risk assessment?A risk assessment is a step-by-step process that, in combination with an exposure analysis and other elements, provides an estimate of the likelihood that an adverse health event will occur as a result of ingestion, inhalation, or absorption of one or more toxins. One of the most important aspects of risk assessment is toxicity assessment.
A toxicity assessment is a study of a substance’s ability to cause harm – and how much harm it can cause. It’s important to note that not all substances are toxic – many therapeutic medications are acute toxic but beneficial when taken at the right dose.

Darwin presented a hypothesis about how evolution takes place. Now this hypothesis has become a theory. What caused the idea to become a theory? A. Darwin shared his ideas with others, and many scientists have performed experiments that support this idea. B. Darwin is well respected, and scientists honor his work by referring to his idea as a theory. C. Darwin performed an experiment that supported his hypothesis. D. Darwin convinced everyone around him that it was a good idea.
Answer:
C. Darwin performed an experiment that supported his hypothesis.
Explanation:
Darwin believed that his experiment, which was comparing the finch's beaks from Galapagos Archipelago, in which there was variation between the size and shape of beaks, as the basis in which he believed evolution was correct. However, variation does not mean evolution, and evolution, in which it calls for a chain of events to create beneficial traits successively, is nigh impossible to occur in the real world. Again, that is not to say that there is no such thing as variation, in which there is, in which people or animal groups adapt to their natural habitat. However, to state that adaptation is proof that a species becomes another is to go out on a limb, and current failures of "new species" (in that it originates from today's day and age, rather then discovered) to emerge is proof of such.

Postpartum urinary retention can be caused by: a. Stretching of the ureters during delivery b. Decreased sensitivity to bladder fullness c. Contraction of bladder muscles caused by oxytocin d. The effects of proteinuria and lactosuria on the bladder
Answer:
a. Stretching of the ureters during delivery
Explanation:
Postpartum urinary retention is defined as the stretching if the uterus or the genitourinary tissue which occurs in most of the women during vaginal deliveries. The postpartum bladder is vulnerable to the urinary retention. This occurs due to the physiological changes in the pregnancy period. During delivery through vagina, the genitourinary tissues becomes edematous and also gets traumatized form the labor process and thus stretches the ureters during the delivery time. But it returns to normal after 4 to 6 days of diagnosis.
Hence the correct option is (a).

Describe the relationship between the surface area and the volume of a cell. Analyze the data and explain why cells are often flattened instead of cube-shaped.
Answer:
Inverse relation.
Explanation:
There is an inverse relationship between the surface area and the volume of a cell because one increases the other decreases. When a cell grows bigger in size, its internal volume enlarges and the cell membrane start expanding. Unfortunately, the volume increases more rapidly than the surface area of the cell. So the surface area available to pass materials to a unit volume of the cell steadily decreases. Cells are often flattened instead of cube-shaped because the surface area increases. Due to surface area increases, more materials to be absorbed through the cell membrane at a greater rate than that of a cell with smaller surface area.

It results in an equilibrium mixture of reactants and products.
Explanation:
A reversible reaction is a type of reaction where reactants react to give rise to products and in the same vein, products react to give rise to reactants again. That is;
A + B (reactants) ⇌ C + D (products)
For example, in the above reaction, C and D are formed simultaneously with the reformation of A and B. Based on this, an equilibrium mixture of reactants and products occurs in a reversible reaction. This means that there is no net change or difference in the formation of A and B or C and D.
