Sample Response: How do mass and the type of material affect thermal energy transfer? What did you include in your question? Check all that apply. examines the effect of mass examines the effect of different materials contains at least two variables
Answers
The question "How do mass and the type of material affect thermal energy transfer?" contains at least two variables, and examines the effect of mass and different materials on thermal energy transfer.
When examining the effect of mass on thermal energy transfer, it is important to note that objects with more mass require more energy to heat up or cool down. This is because they have more particles that need to be heated or cooled.
For example, if you compare a small cup of water and a large pot of water, the pot will take longer to heat up because it has more water and therefore more mass.
The type of material also affects thermal energy transfer because different materials have different thermal conductivities. Thermal conductivity is the rate at which a material can transfer heat, with higher thermal conductivity meaning that the material can transfer heat more quickly. For example, metals generally have higher thermal conductivities than plastics, meaning they can transfer heat more easily.
Overall, understanding the impact of mass and material on thermal energy transfer can help in a variety of contexts, from designing more efficient heating and cooling systems to understanding the physics behind climate change.

dna profiling is based on the slight differences that occur in ____ in the human genome.
Answers
DNA profiling is based on the slight differences that occur in specific regions of the DNA sequence, known as polymorphic regions or genetic markers, in the human genome.
These genetic markers are regions of the DNA that vary in length or sequence between individuals. The most commonly used genetic markers for DNA profiling are short tandem repeats (STRs) or variable number tandem repeats (VNTRs), which are repeated sequences of nucleotides.
By analyzing the variations in these genetic markers among individuals, DNA profiling can create unique genetic profiles that are highly specific to an individual. This allows for accurate identification and differentiation of individuals based on their DNA profiles.

Write a set of directions for a red blood cell to deliver oxygen to the brain. Lungs heart-brain aorta arteries veins
Answers
Answer: How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.OK Our typical red cell passes from the capillary into the venules, and then into veins. It flows back to the right side of the heart, completing the second loop of its circuit [music out]. As we saw, it then travels back to the lungs.The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

Disease or disorder that affects the nervous systems
Answers
Answer:
There are many diseases/disorders that affect the nervous system, but here are a few:
Alzheimer's disease
Parkinson's disease
Epilepsy
Stroke
Explanation:
Alzheimer's disease: Alzheimer's disease is a progressive disease (gets worse and worse overtime) that destroys your memory. When a person has Alzheimer's disease, their neurons (nerve cells) get damaged and eventually die all throughout the brain. Some problems people with this disease can experience are: getting lost easily, personality/behavior changes, memory loss (obviously), and need help with self-care and daily things.
Parkinson's disease: Parkinson's disease is a progressive disorder that affects one's movement. Because the nerve cells are damaged, the dopamine (type of neurotransmitter) levels decrease. Since dopamine can control your body movement, it makes it hard to balance, and you're usually stiff. It usually begins with a tremor in your hand.
Epilepsy: Epilepsy is a neurological disorder where neuron activity in the brain gets disturbed, resulting in a seizure. Epilepsy is usually genetic or gained through a trauma or stroke (brain injuries). During these seizures, people often lose consciousness. Most epileptic people are sensitive to lights (flashing and flickering especially).
Stroke: A stroke occurs when your blood supply to your brain is interrupted/stopped. This is a SERIOUS emergency. Cells can die from lack of blood and the resulting lack of oxygen. Most warning signs of a stroke include: numbness + weakness, trouble speaking, loss of balance, and dizziness.

Why do we have a problem with antibiotic resistant bacteria? bacteria are not affected by antibiotics we are not taking enough antibiotics the bacteria have become immune antibiotics attack viruses no
Answers
Antibiotic-resistant bacteria have developed over time, causing infections that can't be cured with traditional antibiotics. The widespread use of antibiotics is the primary cause of this issue. As a result, many illnesses that were once easily treated are now becoming increasingly difficult to cure.
Antibiotic resistance arises when bacteria are exposed to antibiotics, allowing them to develop the means to resist the drug's impacts. Antibiotic resistance is an issue because it limits the number of antibiotics that can be used to treat bacterial infections, making some bacterial infections difficult or even impossible to cure. Antibiotic resistance is increasing at an alarming rate, and it is becoming a major public health issue.
The inappropriate usage of antibiotics, such as using them for viral infections like colds and the flu, contributes to antibiotic resistance. Antibiotics cannot kill viruses, but they are frequently prescribed when they are not needed or when they will not help. As a result, the use of antibiotics must be closely monitored to reduce the development of antibiotic resistance.
Antibiotic-resistant bacteria are a problem because they limit the effectiveness of antibiotics, making it difficult to treat bacterial infections. Antibiotic resistance is increasing due to the misuse and overuse of antibiotics. As a result, we must use antibiotics responsibly to reduce the risk of antibiotic resistance. we have a problem with antibiotic-resistant bacteria is due to the inappropriate use of antibiotics, which contributes to the development of resistance.

describe three unintended consequences that have occurred in marine ecosystems when top predators are removed
Answers
Smaller, lower trophic level fish populations are kept from destroying ocean ecosystems by top predators. The fact that top predators would feed first on the diseased, disabled, and elderly members of lower trophic levels helps to maintain the health of marine ecosystems.
If top predators are eliminated from a coral reef ecosystem, smaller fish may multiply, allowing for an increase in algae on the corals, which in turn inhibits coral growth. In the absence of predators, prey can overpopulate. In addition to causing disease outbreaks that may spread to domesticated animals, this may also cause harm to nearby flora. Small predators like coyotes are subjugated by top predators like wolves, which controls their populations as well.

an oocyte is an immature reproductive cell found in many sexually reproducing organisms. A crawfish oocyte has a radius of approximately 1mm, while a human oocyte is much smaller and has a radius of about 0.05mm
Surface area of a sphere: A = 4πr2
Assuming both cell types are perfectly spherical, how many times larger is the surface area of a crawfish oocyte compared to the surface area of a human oocyte?
answer choices
100 times larger
200 times larger
300 times larger
400 times larger
Answers
Assuming both cell types are perfectly spherical, the surface area of a crawfish oocyte is 400 times larger than the surface area of a human oocyte. Here option D is the correct answer.
The surface area of a sphere is given by the formula A = 4πr^2. To compare the surface area of two spheres, we need to use the ratio of the surface area of one sphere to the surface area of the other sphere.
Surface area of the crawfish oocyte = 4π(1mm)^2 = 4πmm^2
Surface area of the human oocyte = 4π(0.05mm)^2 = 4π(0.0025mm^2)
The ratio of the surface area of the crawfish oocyte to the human oocyte is:
(4πmm^2) / (4π(0.0025mm^2))
= 1 / 0.0025
= 400
Therefore, the surface area of the crawfish oocyte is 400 times larger than the surface area of the human oocyte. So the answer would be 400 times larger.

for the nucleophile of this reaction, dialkyl phosphonates (diesters of phosphonic acids) are . quizlet
Answers
Dialkyl phosphonates (diesters of phosphonic acids) act as nucleophiles in this reaction.
Dialkyl phosphonates are a class of organic compounds which have the general formula (RO)2P(O)H, where R is a short-chain alkyl group (usually methyl or ethyl). Dialkyl phosphonates act as nucleophiles in reactions, meaning they have a high affinity for positively charged atoms (in this case, the carbonyl carbon of an aldehyde or ketone).
This reactivity is due to the electron-withdrawing properties of the phosphonate group, which makes the carbon more susceptible to attack by the nucleophile. The use of dialkyl phosphonates as nucleophiles is particularly useful in the Horner-Wadsworth-Emmons (HWE) reaction, a type of olefination reaction that allows for the formation of carbon-carbon double bonds between aldehydes or ketones and phosphonate esters.
The reaction is catalyzed by a strong base (usually triethylamine), which deprotonates the phosphonate ester to form a reactive ylide intermediate that can then undergo nucleophilic addition to the carbonyl group of the aldehyde or ketone.
