Levers are defined as the simple machine, which consists of a rod fixed at a pivot, load, and fulcrum. The levers are classified into first class, second, and third class.
The difference between different types of levers are:
1. In the first-class levers, the fulcrum is present between the load and effort. The mechanical advantage can be greater, less, or equal to 1.
2. The class II levers, the load is present between the fulcrum and effort. The mechanical advantage is always greater than the 1.
3. The class III levers, the effort is present between the fulcrum and load. The mechanical advantage is always less than 1.
Thus, the correct answer is Option 1.

Answer:
Some cancers are diagnosed only after symptoms develop. And this may be after the disease has spread or a tumor has grown large enough to be felt or seen in imaging tests.
But many types of cancers can be diagnosed early, before symptoms form. You have the best chance at survival and a healthy quality of life if your cancer is diagnosed and treated in its early stages.
Other cancers can form and grow undetected for 10 years or more

Explanation:
how do the intrinsic muscles of the hand and foot differ in function?
Answer:
In normal hand function, the intrinsic muscles, both the lumbricals and interosseus muscles balance finger movement7 and create this broad sweeping movement. Besides abducting and adducting the fingers, they are responsible for coupling metacarpophalangeal joint (MCP) flexion with interphalangeal joints (IP) extension
The intrinsic foot muscles act to stabilise the foot and support the arches, as well as to produce fine movement of the toes. The intrinsic foot muscles can be divided into two main groups, plantar and dorsal.

become a little more acquainted with some of the people affected by HIV and AIDS, perform a keyword search on the Internet and find a
video that includes an interview with teenagers who are HIV-positive. You may want to include the keywords HIV, positive, and teens in your
search.
Answer:
Young people are vulnerable to HIV at two stages of their lives; early in the first decade of life when HIV can be transmitted from mother-to-child, sometimes known as vertical transmission (see children and HIV), and the second decade of life when adolescence brings new vulnerability to HIV.
Around 70% of adolescents living with HIV will have acquired it through vertical transmission and so will have been living with the virus since birth.18 Whilst programmes to prevent mother-to-child transmission (PMTCT) have been hugely successful in recent years, reducing new infections among adolescents is more difficult.19
There are many factors that put young people at an elevated risk of HIV. Adolescence and early adulthood is a critical period of development when significant physical and emotional changes occur. Adolescents and young people have growing personal autonomy and responsibility for their individual health. The transition from childhood to adulthood is also a time for exploring and navigating peer relationships, gender norms, sexuality and economic responsibility.20
Considerable data gaps exist in our knowledge of HIV among adolescents and young people. This is particularly the case for younger adolescents because of the challenges in getting parental approval for their involvement in surveys and a lack of age-appropriate questions. Where data exist, limited sample sizes and lack of disaggregation limits the available evidence to inform programming. In part because of these gaps, adolescents and young people are often missing from national HIV strategic plans, particularly interventions beyond PMTCT.21
Explanation: Excluding vertical transmission, unprotected sex is the most common route of HIV infection for young people, with sharing infected needles the second.22 For some, this is a result of not having the correct knowledge about HIV and how to prevent it, highlighting the need for HIV and sexual and reproductive health and rights (SRHR) education. For others, it is the result of being forced to have unprotected sex, or to inject drugs.23

4. A client is diagnosed with chronic kidney failure and is unable to excrete the nitrogenous waste products that build up. What diagnostic test results would the nurse expect to observe related to the waste build up? Select all that apply. a. Low potassium level b. Elevated BUN (blood urea nitrogen) C. Elevated uric acid levels I d. Elevated creatinine levels e. Elevated hemoglobin
Answer: Urea is made in the liver and passed out of your body in the urine. A BUN test is done to see how well your kidneys are working. If your kidneys are not able to remove urea from the blood normally, your BUN level rises. Heart failure, dehydration, or a diet high in protein can also make your BUN level higher.

Which of the following is an advantage of the lactic acid system?
Answer: You should list the answer choices, however if you cannot, I will list all of the advantages of the lactic acid system:
Provides more sustained high-intensity energy for between 10 and 180 seconds.Can work both anaerobically (without oxygen) and aerobically (with oxygen).There is a huge amount of glycogen stored in the muscles and liver which can be made available for energy.Fewer reactions than the aerobic energy system are needed to produce energy so it is faster (but not as fast as the PC system). It is more efficient than the ATP-PC system as the lactic acid system resynthesises two molecules of ATP as opposed to just one that the ATP-PC manages.Answer: Energy that Produces Quickly "Produces energy quickly."
Explanation: The energy that produces quickly is an advantage to the Lactic Acid System because the Lactic Acid System breaks down glycogen in the muscles into glucose, which can then be used to generate ATP for energy.
what is the recommended depth of compressions in infants
Answer:
For infant and child resuscitation, current basic life support guidelines recommend a compression depth of one third to one half of the anteroposterior chest diameter
Explanation:
In infants, the optimum compression depth is 1.5 inches (4 cm). This is roughly one-third of the chest's depth. Compressions should be conducted at a rate of 100 to 120 compressions each minute.
It is vital to note that the depth of the compressions will vary according to the infant's size. The compressions may need to be shallower if the infant is very little. The compressions might have to be deeper if the infant is larger.
It is also critical to ensure that the compressions are carried out correctly. Two fingers should be placed in the center of the chest, right below the nipples, by the rescuer. The fingers should be put on the chest directly, not on top of garments.
