Why are models in science used to represent complex processes?
“Scientific models are often used in laboratories to represent Earth's processes. While field tests and observations are vital, physical, digital, and mathematical models are useful tools in the laboratory. Models provide insight into complex processes that might otherwise be difficult to grasp”
Which process forms new elements
Answer:
**nuclear fusion**
So creating a brand new element requires loading an atom's nucleus with more protons. Stars create new elements in their cores by squeezing elements together in a process called nuclear fusion. First, stars fuse hydrogen atoms into helium.
Which of the following is true regarding prenatal tests?
All prenatal tests are safe for the mother and her unborn baby.
Amniocentesis is less risky than the AFP blood test.
Amniocentesis and chorionic villi sampling are the prenatal tests that pose the highest risk to the pregnant woman and her unborn baby.
All prenatal tests are unsafe and should not be performed.
A screening test is a procedure or test that is done to see if a woman or her baby might have certain problems. A screening test does not provide a specific diagnosis—that requires a diagnostic test (see below). A screening test can sometimes give an abnormal result even when there is nothing wrong with the mother or her baby. Less often, a screening test result can be normal and miss a problem that does exist. During pregnancy, women are usually offered these screening tests to check for birth defects or other problems for the woman or her baby. Talk to your doctor about any concerns you have about prenatal testing.
First Trimester Screening
First trimester screening is a combination of tests completed between weeks 11 and 13 of pregnancy. It is used to look for certain birth defects related to the baby’s heart or chromosomal disorders, such as Down syndrome. This screen includes a maternal blood test and an ultrasound.
Maternal Blood Screen
The maternal blood screen is a simple blood test. It measures the levels of two proteins, human chorionic gonadotropin (hCG) and pregnancy associated plasma protein A (PAPP-A). If the protein levels are abnormally high or low, there could be a chromosomal disorder in the baby.
Ultrasound
An ultrasound creates pictures of the baby. The ultrasound for the first trimester screen looks for extra fluid behind the baby’s neck. If there is increased fluid found on the ultrasound, there could be a chromosomal disorder or heart defect in the baby.
Second Trimester Screening
Maternal Serum Screen
The maternal serum screen is a simple blood test used to identify if a woman is at increased risk for having a baby with certain birth defects, such as neural tube defects or chromosomal disorders such as Down syndrome. It is also known as a “triple screen” or “quad screen” depending on the number of proteins measured in the mother’s blood. For example, a quad screen tests the levels of 4 proteins AFP (alpha-fetoprotein), hCG, estriol, and inhibin-A. Generally, the maternal serum screen is completed during the second trimester.
Fetal Echocardiogram
A fetal echocardiogram is a test that uses sound waves to evaluate the baby’s heart for heart defects before birth. This test can provide a more detailed image of the baby’s heart than a regular pregnancy ultrasound. Some heart defects can’t be seen before birth, even with a fetal echocardiogram. If your healthcare provider finds a problem in the structure of the baby’s heart, a detailed ultrasound may be done to look for other problems with the developing baby.
Anomaly Ultrasound
An ultrasound creates pictures of the baby. This test is usually completed around 18–20 weeks of pregnancy. The ultrasound is used to check the size of the baby and looks for birth defects or other problems with the baby.
Diagnostic Tests
If the result of a screening test is abnormal, doctors usually offer further diagnostic tests to determine if birth defects or other possible problems with the baby are present. These diagnostic tests are also offered to women with higher risk pregnancies, which may include women who are 35 years of age or older; women who have had a previous pregnancy affected by a birth defect; women who have chronic diseases such as lupus, high blood pressure, diabetes, or epilepsy; or women who use certain medications.
Chorionic Villus Sampling (CVS)
CVS is a test where the doctor collects a tiny piece of the placenta, called chorionic villus, which is then tested to check for chromosomal or genetic disorders in the baby. Generally, a CVS test is offered to women who received an abnormal result on a first trimester screening test or to women who could be at higher risk. It is completed between 10 and 12 weeks of pregnancy, earlier than an amniocentesis.
Amniocentesis
An amniocentesis is test where the doctor collects a small amount of amniotic fluid from the area surrounding the baby. The fluid is then tested to measure the baby’s protein levels, which might indicate certain birth defects. Cells in the amniotic fluid can be tested for chromosomal disorders, such as Down syndrome, and genetic problems, such as cystic fibrosis or Tay-Sachs disease. Generally, an amniocentesis is offered to women who received an abnormal result on a screening test or to women who might be at higher risk. It is completed between 15 and 18 weeks of pregnancy. Below are some of the proteins for which an amniocentesis tests.
AFP
AFP stands for alpha-fetoprotein, a protein the unborn baby produces. A high level of AFP in the amniotic fluid might mean that the baby has a defect indicating an opening in the tissue, such as a neural tube defect (anencephaly or spina bifida), or a body wall defect, such as omphalocele or gastroschisis.

how are food prices affected by a supply and demand
Explanation:
Food prices are affected by supply and demand because when you have more of something it would be cheaper than the less you have of something the more it would cost because there isn't as much as the product
Answer:
They affect the demand in that if the food is too expensive, people might not want to buy it anymore. It can also go the other way; if food prices drop, then the demand might increase due to the lowered prices.

Kinesiology studies how the body initiates and controls movement, beginning with the brain
and using interactions of different body systems. The body moves when internal and external
forces act on it. Internal forces are generated within the body, while external forces are generated outside of the body.
Internally, muscles generate force as they contract and bones generate movement. Which
statement accurately represents how forces affect motion in organisms?
O When a muscle relaxes, it applies a pulling force on a bone, causing it to move.
O When a bone relaxes, it applies a pushing force on a muscle, causing it to move.
O When a muscle contracts, it applies a pulling force on a bone, which causes movement.
O When a bone contracts, it applies a pushing force on a muscle, which causes movement.
Answer: When a muscle contracts, it applies a pulling force on a bone, which causes movement
Explanation:
The statement that muscle contract is causing application of a pulling force on a bone and that it is causing movement is representing how forces are affecting motion in organisms od the human body.
The process of muscle contract is called contraction. These muscles are attached to bones that are found in the human body and they are attached to them by strong tendons. When it comes to the contraction process, the muscle is pulling on the bone.
Which learning theory involves the concept of successive approximation?
A.
conditioning and social learning
B.
social learning
C.
classical conditioning
D.
operant conditioning
The successive approximation is a technique used to promote learning by psychologist B. F. Skinner, in operant conditioning.
What is successive approximation?It is a learning paradigm that is part of operant conditioning, in the context of applied behavior analysis, which was developed by Burrhus Frederick Skinner.
Behavioral shaping is normally carried out through the method of procedures that are based on the progressive modification of an existing response in the behavioral repertoire of the learner.
Therefore, we can conclude that successive approximation is one of the operant techniques used to develop behaviors.

Which is NOT a reason STDs go undiagnosed?
a. State laws require all STDs to be reported.
b. Many STDs are asymptomatic.
c. If symptoms disappear, a person might think the STD is gone.
d. Some people are embarrassed to ask for help.
please help
Answer:
the answer is a
Explanation:
stds do not have to be reported to the govt
A reason that STDs go undiagnosed is that state laws require all STDs to be reported, which is option a. State laws requiring the reporting of STDs actually help in their diagnosis and tracking. So, the correct option is option a.
Many STDs do not cause noticeable symptoms or may only cause mild symptoms that can be easily overlooked or mistaken for other conditions. As a result, individuals may not seek medical attention or testing, assuming they are not infected. Some STDs, such as chlamydia or gonorrhea, can cause symptoms that resolve on their own, leading individuals to believe the infection has cleared without treatment. The stigma surrounding STDs and discussions about sexual health can prevent some individuals from seeking medical attention or discussing their concerns openly with healthcare providers. So, the correct option is option a.
