A. To decrease spread of bloodborne pathogens
B. To decrease lethality from needle shock
C. To decrease clotting resulting from dirty machinery
D. To decrease plasmapheresis of the blood
Answer:
D. To decrease plasmapheresis of the blood.
Explanation:
Plasmapheresis is a process in which plasma (which is what is being donated) is separated from the blood cells. Usually, the plasma is replaced with another solution such as saline or albumin, or the plasma is treated and then returned to your body.(or the patient)

300 million years ago, Wisconsin was once covered with rock, while West
Virginia was covered with swamps. Why do you think West Virginia today
produces a lot of gas and oil, while Wisconsin does not?
Answer: Because West Virginia had more density of organic materials back in that time.
Explanation:
This is because gas and oil is produced by the decomposition of organic materials.
As virginia was covered with swamps, under the actual surface we can find a lot of organic material (the remains of the swamps and such) while in Winsconsin, under the surface there are mostly rock, so there is not a lot of organic material that can be descomposed to produce oil or gas.
Look at the data table. If you were to make a bar
graph from this data, which organisms would be
represented by the tallest bar?
wolves
bears
bison
elks
please help
Hello there!
The elks would be represented by the tallest bar in a bar graph since their population exceeds the population of the other organisms shown in the chart combined altogether.
35,000 > 2,710
Answer:
Elks
Explanation:
The tallest bar will be the organism with the greatest population.
The wolves have a population of 180, the bears population is 610, the bison population is 2,000 and the elks population is 35,000.
35,000 is much greater than any other number, so the elks will have the tallest bar.

As a seedling , the strangler fig and host tree have a relationship that is described as commensalism . Why is commensalism a good description for this relationship ?
Answer:
It merely uses the host tree to get closer to the sunlight and rain, and finds nutrients in decaying leaves and soil caught in nooks of the host tree's branches . This is a case of commensalism: one organism benefits while the other is unaffected.
Explanation:
The relationship between the strangler fig and a host tree would be described as commensalism because the strangler benefits from the relationship while the host tree is unaffected.
Commensalism refers to a relationship between two organisms in which one of them (the commensal) benefits and the other (the host) is unaffected in any way.
As a seedling, the strangler fig grows harmlessly around the a host tree. As the seedling develops to a more mature plant, it starts extending its branches and roots around the host plant, eventually strangulating the host plant.

An energy pyramid shows how energy flows through an ecosystem. An image is provided. Each level gets only about 10% of the energy from the previous level. If living systems follow the law of conservation of energy, where does the remaining 90% of the energy go?
A. A It is used by decomposers during decomposition.
B. B It is converted into heat and energy for life functions.
C. C It is converted to matter during digestion.
D. D It is used by organisms in the lower trophic level.
Answer:
b
Explanation:
some is used, some is wasted by giving off heat, being excreted, etc
The statement (B) is correct. It is converted into heat and energy for life functions.
What is an ecosystem?An ecological pyramid is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
Moreover, an energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level. The energy in an energy pyramid is measured in units of kilocalories (kcal).
Therefore, a pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.

Explanation:
Arnold is reviewing the Miller-Urey experiment and similar experiments on the origins of life on Earth. In each of these experiments, several
inorganic gases were mixed in a chamber to simulate the atmosphere of early Earth. Then the gases were subjected to a spark of electricity,
which simulated a lightning bolt. The gases reacted to form simple amino acids and other organic compounds.
Arnold claims that the results of the experiments show how the first organic molecules formed on Earth
Which statement is the best evaluation of Arnold's claim?
A The claim is well justified. The results were verified by many experiments
B. The claim is well justified. The experiments tested all of the possible mechanisms for making organic molecules.
C. The claim is poorly justified. The experiments tested only one mechanism for making organic molecules; other mechanisms may exist.
D The claim may or may not be justified, depending on the conclusions of the scientists who completed the experiments.
Answer:
C. The claim is poorly justified. The experiments tested only one mechanism for making organic molecules; other mechanisms may exist.
Explanation:
The Miller-Urey experiment is a classic experiment and it has been used to support a hypothesis that states that abiotic synthesis in the early Earth was the cause of the formation of the organic molecules required for the life. However, although this experiment is a classic that showed how organic molecules could have derived from a primitive atmosphere, it was an experiment in controlled conditions, thereby it is imperative to obtain real evidence to support the fact that the first organic compounds were formed on early Earth.

The graph below shows drug levels in the blood and in a target organ through time, while taking Pill Type C in the Gizmo. The dosage schedule is one pill every two hours. What will eventually happen if the patient continues to take the pill on the same dosage schedule?
Answer:
I don't know man
Explanation:
Answer:
Correct Answer: B. The drug level in the target organ will level off and reach equilibrium.
Explanation:
As long as the dosage schedule is maintained, the drug level in the target organ and blood will stabilize. The reason for this is that as the concentration of drug increases in the organ and blood, the amount of drug removed by the kidneys increases as well, as each cubic centimeter of liquid removed from the blood by the kidneys contains a greater amount of drug. Eventually, the amount of drug removed in the time period between pills is equal to the amount that is added with each pill. As the graph below shows, the maximum organ drug level in this example is about 192 mcg/cc.

When Mendel crossed tall pea plants with short pea plants all of the offspring were tall. Which of the following explains the tall gene?
A) The tall gene is peas is recessive
C) The short gene is peas is dominant
B) The short gene in peas is recessive
D) The tall gene in peas is dominant
Answer: D: The tall gene in peas is dominant
Explanation:
When alleles are heterozygous, dominant genes will "overpower" the recessive gene.
The offspring in the pea plants had both alleles of the gene, but despite this, all of the pea plants were tall. This is because the dominant gene, the tall gene, was expressed over the recessive gene.
The correct answer is D.
B is also correct, but the question asks us to explain the tall gene, not the short one.

Which of the following is a function of the kidneys?
O A. To balance water and salts from food so cells neither shrink nor
burst
O B. To balance carbon dioxide and oxygen so cellular respiration can
occur
O C. To filter out fiber and bacteria and send them to the large intestine
O D. To filter out salts and fats and send them to the urinary bladder
Answer:
D. To filter out salts and fats and send them to the urinary bladder
Explanation:
Kidney is an excretory organ in the systems of certain living organisms e.g humans. It is a bean-shaped organ responsible for getting rid of waste products in our body via urine and maintaining homeostasis in the body.
Among the many excretory functions of the kidney, they help filter out electrolytes e.g salts and fats out of the blood and pass them to the urinary bladder through tubes called ureter. The waste products are eventually passed out as urine from the bladder.

why is East Ferris running out of water
Answer:
East Ferris running out of water because the amount of available freshwater decreases when people use more than the amount that flows into their area.
East Ferris running out of water because the population of East Ferris is increasing over time, but the amount of rainfall in East Ferris stays about the same over time.
How is East Ferris running out of water?The population of East Ferris is increasing over time, but West Ferris is not running out of water because it rains more in West Ferris than in East Ferris.
In East Ferris, the population is increasing with time, but the amount of rainfall in East Ferris remains similar with time. The wind is moving in the direction from east to west and having upward movement of the humid air which gets cool and the condensation of water vapors takes place into clouds and falling of rain takes place.
Therefore, East Ferris is increasing over time, but the amount of rainfall in East Ferris stays the same.
