Answers

Cardiac transplantation in the united states: an analysis of the UNOs registry is a research paper by Matthew J. Everly.

What is the abstract?

For people with advanced heart disease, cardiac transplantation is a crucial choice. The number of heart transplants carried out annually in the US is around 2,000. Due to a shortage of contributors, this figure has stayed fairly steady. Coronary artery disease and dilated cardiomyopathy were the two main causes of cardiac transplants prior to the last 20 years, however dilated cardiomyopathy has since replaced coronary artery disease as the leading factor.

With the introduction of more recent immunosuppressive drugs, survival rates have increased (tacrolimus and mycophenolate). For 43,906 heart transplants, the median survival time was around 9 years. The survival rate was still declining at 20 years, reaching only 10%. Seven-year survival rates were 59%, 62%, and 65%, respectively, for patients who received heart transplants between 1998 and 1994, 1995 and 2000, and 2000 and 2007.

A student performed an experiment to see if water temperature affects the level of activity in aquatic snails. The student set up four tanks with five snails in each tank. All four of the setups were identical in every way, except for the temperature of the water. In order to make the conclusions more valid, the student could.

Answers

In order to make the conclusions more valid, the student could use a large number of snails.

The accuracy and validity of a research's findings are influenced by the size of the sample taken from the population of interest. The following method for calculating sample size to be selected during a research can be used to calculate the influence of sample size:

(Z - score)² × SD × (1 - SD) / ME² = Sample size

Where Z-score ⇒ confidence level

SD ⇒ Pre-determined standard deviation

ME ⇒ Margin of error.

The sample size has an inverse relationship with the margin of error. As a result, the error margin decreases as the sample size increases and vice versa.

By using more snail samples in each of the tanks, the student might have improved the validity of the research's findings.

Therefore, using a larger number of snails would improve the conclusion. This is because the quantity of snails tested raises the validity of a research report. The validity of the claim is higher and more credible if 10 snails rather than 5 are more active in warmer water.

Thus, option 4 is the right answer.

Ivan pavlov conducted an experiment where he wanted to train his dogs to drool at the sound of a bell. Which one of the following is the unconditioned stimulus?.

Answers

In Ivan pavlov experiment food is the unconditioned stimulus and dogs salivating for food is the unconditioned stimulus.

What is unconditioned response stimulus?

In classical conditioning, an unconditioned response occurs naturally in reaction to unconditioned stimulus. For example smell of food is an unconditioned stimulus and feeling of hunger in response to smell is an unconditioned response.

Here Ivan pavlov conducted experiment with dogs which salivated in response to a bell ring. Pavlov fed the dog by ringing the bell each time, the dog learned to associate the sound with the presentation of food.

Pavlov noticed that the dogs physical reactions to food subtly changed over time. At first dogs would salivate only in the presence of food but after conducting experiment dogs gets addicted to the sound which was rang before it is fed with food.

How are scientific inferences are drawn from scientific observations? Provide examples from your lab work and what you've learned about cells.

Answers

Inference is what we draw from observations, whereas observation is what we perceive when something occurs. Hence they are interrelated.

What are Observation and Inference?An observation is a practice of observing someone or something closely while it's happening and learning from it. Inference is the process of drawing a reasonable conclusion from known facts or conditions.Based on firsthand experience, observation is made. Unlike inference, which is predicated on known facts.

Example from lab work:

To ensure that all the starch is consumed, place a healthy potted plant in a dark room for 48 hours.Now, secure one of the plant's leaves with a paper clip to a black piece of paper.For around six hours, keep this plant in direct sunshine.Pick the uncovered and covered leaves off the plant, respectively.The leaves should be briefly submerged in boiling water.Now submerge the leaves in an alcohol-filled beaker.Put this beaker carefully in a water bath and heat it until the alcohol starts to boil.Take note of the solutions and leaves colors. With lots of fresh water, wash the leaves.Now soak the leaves for a few minutes in the iodine solution.Compare the observations of the color of the leaves.

Observation:

Alcohol solution turns green when leaves are boiled in it, while the leaves lose their color.When iodine solution is applied to leaves, (a) a leaf coated in black paper did not exhibit any color changes. (b) Another leaf that wasn't coated in black paper turned blue-black when dipped in diluted iodine solution.

Inference:

Starch is created by plants during photosynthesis.Since the leaf cannot receive sunlight when it is covered, no starch was created in the leaf.Iodine solution turns blue-black when starch is included. Iodine solution was applied to the covered leaf, but no color change was noticed. It means that this leaf did not produce any starch.The exposed leaf received sunshine for six hours, but when iodine solution was applied, the color turned blue-black.This demonstrates that photosynthesis depends on sunshine.

since cells are filled with water, what would happen to biologically important molecules if they were held together with ionic bonds?

Answers

Ionic bonding involves electrostatic interactions between oppositely charged ions, and can significantly enhance the binding strength of biomolecules immobilized to materials.

A chemical link known as an ionic bond occurs when an electron is transferred from one atom to another. Ionic bonding requires the presence of an electron acceptor and an electron donor, which is frequently a metal (often a nonmetal). Electrovalence is the process of moving electrons. A positive ion, also known as a cation, is created when an atom loses one or more electrons. The other atom that picks up one or more electrons will change into a negative ion known as an anion. The elemental name is modified by adding a -ide at the end to designate the ion that accepts the electron. For instance, the name of the anion of chlorine is chloride while the anion of sulfur is sulfide.

A mutation that affects only the DNA sequence and not the amino acid sequence is known as a silent mutation. Introns, which are spliced off prior to translation, are susceptible to silent mutations.

Several mutagens, or compounds that alter the DNA sequence, can generate silent mutations, Mutations are caused by living things or processes that support life. For example, certain viruses insert copies of their genetic code into the DNA of their hosts. Silent mutations are typically not the outcome of such extensive change.

Chemical mutagens are chemicals that interact with DNA to chemically change the nucleotides.

Base analogues are substances that resemble nucleotide bases structurally. These may result in base-pair mismatches that are integrated into the DNA sequence of the mutation, leading to silent (and other) mutations.
