If plaque buildup reduces the radius of the artery by a factor of 2, by what factor does the flow rate change?
If plaque buildup reduces the radius of the artery by a factor of 2, the flow rate becomes 1/16th of the original.
Coronary heart disease results from a deposition of plaque in the blood vessels which transport blood to the heart. When the flow of blood to the heart is hampered or obstructed, the heart can be harmed due to a deficiency of oxygen.
Moreover, if a large section of plaque that is deposited gets displaced from an artery wall, it can get stick in other arteries in the body as well, including those present in the brain.
For convenience, an assumption can be made that the artery is cylindrical in shape with a radius of R. The flow rate of a viscous fluid (blood in this case) is determined by Poiseuille's Law, i.e. Q = (π/8) (ΔP/ηl)r4.

In areas that are hard hit by natural disasters, many people are unable to purchase property insurance. Defend your stance on providing or not providing insurance in these disaster areas.
Answer:
I personally used to live in Florida when i was little and I went through one hurricane and it absolutely destroyed our house. Unfortunately we did not have property insurance and we had to pay out of pocket for repairs. I believe everyone should be able to be provided with property insurance in these disaster areas. In the text, It states "Property damage from Hurricane Katrina and costs to rehabilitate or rebuild the area may exceed $100 billion, making it the most costly hurricane in U.S. history." Thats a lot of money to recuperate and still some people hadn't recovered in some areas.
Explanation: I got 100% ur welcome:)
Insurance should be provided for these areas because people are in need. This insurance should be buyable like car or home insurance. If wreckage to these places happens so often I think it would be silly not to have back up in this form. Personally I would just move out of the area and to some place safer. - 100%

3 States of Matter
Categories of Biodiversity
Answer:
Frequency: The rate that sound or other waves vibrate at
Frequency: The rate at which something happens
wavelength: wavelength -- the distance (measured in the direction of propagation) between two points in the same phase in consecutive cycles of a wave
wavelength: wavelength -- a shared orientation leading to mutual understanding; "they are on the same wavelength"
energy: Power that makes machinery work
energy: The physical and mental effort used to do things
Electromagnetic energy is a term used to describe all the different kinds of energies released into space by stars such as the Sun. These kinds of energies include some that you will recognize and some that will sound strange. They include: Radio Waves. TV waves.
Reflection: A reflection shows what something is like
Reflection: The image that reflected from or in something
Refraction: refraction -- the change in direction of a propagating wave (light or sound) when passing from one medium to another
Refraction: deflection, deflexion, refraction -- the amount by which a propagating wave is bent
Absorption: absorption, soaking up -- a process in which one substance permeates another; a fluid permeates or is dissolved by a liquid or solid
Absorption: absorption -- the physical process in which incident radiated energy is retained without reflection or transmission

Describe the general flow of energy through an ecosystem beginning with the Sun and going through a third order consumer.
Answer:
1) Autotrophs transform solar energy into chemical energy.
2) Herbivores and omnivores (primary consumers) eat producers, make use of some of the energy, making from it their biomass.
3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy.
4) Decomposers (last order in the chain) recycle all the dead organic material and make use of some of the stored energy.
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, only 0.1 or 1% is absorbed by autotroph organisms or producers.
From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment.
Organisms that can use light, and turn it into organic matter according to their own needs are producers, and they are called autotrophic organisms. These organisms are by excellence all plants, algae, and bacteria that photosynthesize. Organisms that are incapable of producing their food are called heterotrophic. They depend on other organisms from the trophic chain such as plants or other animals to feed on, so they can get proteins and energy. In the trophic web, heterotrophic organisms occupy the first, second, or third consumer level, after producers. There are different types of heterotrophic animals: carnivorous, herbivorous, omnivorous, hematophagous, ichthyophagous, and etcetera. All of them depend on autotrophic organisms.
At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.
The progressive reduction of energy determines the number of trophic levels in the chain (4 or 5).
1) Autotrophs use water, CO2, and solar energy to produce O2 and glucose, by the process of photosynthesis and convert it into biomass. Producers transform solar energy into chemical energy.
2) Herbivores and omnivores (primary consumers) make use of some of this energy to survive, making from it their biomass. The rest of the energy is lost.
3) Following, carnivores or predators (secondary, tertiary, and other consumers) eat herbivores, using only 10% of the flowing energy. The rest of the energy is lost.
4) When different organisms die, decomposers (last order in the chain) recycle all the organic material and make use of some of the energy stored in their tissues. The rest is lost.

how many times has neptune completed a revolution around the sun since its discovery
Since its discovery in 1846, Neptune has completed one full revolution around the Sun.
As of my knowledge cutoff in September 2021, Neptune orbital period, or the time it takes to complete one orbit around the Sun, is approximately 164.8 Earth years. Therefore, it would have completed slightly more than one revolution around the Sun since its discovery in the 19th century. Since Neptune's orbital period is approximately 164.8 Earth years, it means that it takes that amount of time for Neptune to complete one full revolution around the Sun.This means that if we consider the time from Neptune's discovery in 1846 until September 2021, it would have completed slightly more than one revolution around the Sun.

When our prehistoric ancestors studied the night sky they noticed that 5 objects moved through the constellations, what are these called?
Answer:
planets
Explanation:
In the past, it was observed that little points of light moved through the constellations. Nowadays, we known that these points are planets which orbit around the sun, while stars remain fixed in the sky. This phenomenon is due to the fact that planets are so much closer to the Earth than the stars. From Earth, five planets can be seen with naked eyes (i.e., Jupiter, Saturn, Mars, Venus and Mercury).

The statement which is NOT true of osmotic saline laxatives is "They work in response to the amount of medication given, making water replacement insignificant".
Osmotic saline laxatives are used to relieve constipation. They are often prescribed by doctors to relieve constipation because they work by increasing the amount of water in the large intestines and feces. However, they work by pulling water into the large intestine through osmosis, causing the stool to soften and pass out easily. Osmotic saline laxatives are available in various forms. They include milk of magnesia. These laxatives can be dangerous to use for people with heart disease and hypertension because of the fluid retention caused by the osmosis.
Cephulac contains fructose and lactose and should be used with care for persons with diabetes. Hence, the correct option is "They work in response to the amount of medication given, making water replacement insignificant".

Yes, neurotransmitters function as ligands on the postsynaptic neuron. Ligands are molecules that bind to a receptor on a cell, and this binding triggers a biological response. Neurotransmitters are chemical messengers that transmit signals between neurons across the synaptic gap. These chemicals are released by the presynaptic neuron and bind to receptors on the postsynaptic neuron, acting as ligands. The postsynaptic neuron has specialized receptors on its surface that are activated by specific neurotransmitters. The neurotransmitters bind to these receptors, triggering a cascade of intracellular signaling events that lead to changes in the postsynaptic neuron's membrane potential, either increasing or decreasing the likelihood of an action potential. In conclusion, neurotransmitters function as ligands on the postsynaptic neuron, binding to specialized receptors and initiating a cascade of intracellular signaling events.

describe the locations and functions of the sensory, association, and motor areas of the cerebral cortex.
The cerebral cortex can be divided into three major functional areas. These are: Sensory areas, Motor areas, Association areas.
What are the locations and functions of the areas of cerebral cortex?Sensory areas: These areas are those that receive and process data from the sense organs. Vision is sensed by the main visual cortex. The primary auditory cortex and primary somatosensory cortex, respectively, are responsible for perceiving hearing and touch. In the temporal lobe's superior temporal gyrus is the primary auditory cortex. The parietal lobe houses the primary somatosensory cortex, while the occipital lobe houses the primary visual cortex.
Motor areas: Both hemispheres of the cortex contain the motor regions. These play a major role in the regulation of volumtary movements. The left side of the body is controlled by the right half of the motor region, and vice versa.
Association areas: They integrate information from different receptors or sensory areas and relate the information to past experiences. The association area is located in frontal lobes.

the mouthparts of different insects are used for different purposes. the grasshopper, for example, primarily bites and chews while the honeybee bites and the butterfly sucks nectar. are these structures homologous?
Answer:
The mouthparts of different insects are not considered to be homologous, or derived from a common ancestor. Instead, the different mouthparts of insects are considered to be examples of convergent evolution, where different species have independently evolved similar structures to perform similar functions.
In the case of the grasshopper, the honeybee, and the butterfly, their mouthparts are all adapted to their respective feeding habits. The grasshopper has strong mandibles for biting and chewing plant material, the honeybee has a proboscis for sucking up nectar and other liquids, and the butterfly has a long, tubular proboscis for sucking up nectar from flowers. Although these structures may appear similar, they are not considered to be homologous because they have evolved independently in response to the different feeding habits of the insects.
