Which property of minerals is the least reliable for identifying minerals?
hardness
luster
streak
color
Answer:
color.
Explanation:
Although color is the most obvious of mineral properties it is the least reliable for identification purposes. This is because the color of a mineral can be altered by slight chemical impurities within its crystal structure.
The color of a mineral is the least reliable for identifying minerals. Therefore, option D is correct.
What are the properties of minerals?A mineral species is identified by two distinct characteristics: its crystal structure and chemical composition. Each mineral has a unique three-dimensional arrangement of the atoms that make up its structure. Its physical characteristics, including cleavage and hardness, are impacted by its regular geometry.
Because they are composed of many elements, minerals have unique qualities. Iron, calcium, magnesium, silicon, carbon, phosphorus, oxygen, and many more naturally occurring elements can be found in minerals. Based on how many electrons each of these native elements have, they have various qualities.
The color of a mineral is the least reliable for identifying minerals. Therefore, option D is correct.

Diabetes is a disease caused by the inability of the pancreas to produce insulin as the body needs it. Insulin is a hormone that regulates the breakdown of glucose for energy. People who have this disease, often have to take in additional insulin. E. coli bacteria can be altered to produce synthetic insulin in the laboratory.
A.
The insulin produced by bacteria can be used to help treat people with diabetes.
B.
E. coli bacteria are one of the main causes of the disease, diabetes.
C.
The bacteria can be injected into a person with diabetes and permanently cure him or her.
D.
all of these
Insulin is a hormone that regulates the breakdown of glucose for energy insulin produced by bacteria can be used to help treat people with diabetes.
What is the function of insulin?Numerous toddlers and teenagers suffer from the dangerous condition known as type 1 diabetes. Insulin, a hormone that controls blood sugar levels, is no longer produced by the pancreas as a result of the condition.
The smallest blood vessels in the body eventually suffer harm from high blood sugar levels. In order for blood sugar to be utilized as fuel by the body's cells, insulin aids in its absorption.
The liver receives a signal from insulin to store blood sugar for later use. When blood sugar enters cells, blood sugar levels fall, which tells insulin to do the same.
Therefore, glucose from the blood can be absorbed by the cells in the muscles, fat, and liver by insulin, hence option A is correct.

Petroleum products, which contain carbon, are burned, and the carbon escapes into the atmosphere, as carbon dioxide, BUT, how does it get into the petroleum in the first place?
Answer:
they got there because of the chemicals that the carbon has
Explanation:
Carbon from plants and animals that lived millions of years ago is stored in rocks like limestone and fossil fuels like coal and oil. Slow geologic processes trapped the carbon from these organisms' deaths and converted it into these natural resources.
What form of carbon is in fossil fuels?As previously stated, fossil fuels are hydrocarbons. When hydrocarbons are burned in the presence of oxygen, carbon dioxide is released into the atmosphere. Carbon dioxide is a greenhouse gas that contributes significantly to global warming.FOSSIL FUEL : The compounds that make up plankton and plants transform into fossil fuels after millions of years underground. Plants decompose into coal while plankton decomposes into natural gas and oil.Carbon compounds are used as fuel because they burn cleanly and produce no smoke. Carbon compounds have higher calorific values, a higher maximum ignition temperature, and their combustion is more controlled. As a result, carbon and its compounds are an excellent source of fuel.To learn more about : Fossil fuels

write a mini-essay about Balanced & Unbalanced Forces
Answer:
Forces have a magnitude (strength) and a direction. Forces can be represented as arrows with the length of the arrow representing the magnitude of the force and the head of the arrow pointing in the direction of the force. Using such arrows, the resulting force (net force) and direction can be determined.
Forces acting on an object can be balanced or unbalanced.

2. Some types of syrup are almost entirely made of glucose molecules. If a person ate some syrup like this, what would happen to her ability to exercise?
A. It would be harder for her to exercise because her digestive system would need to use more enzymes to combine the glucose molecules together.
B. It would be easier for her to exercise because glucose moves through the circulatory system faster than other food molecules usually do.
C. Nothing would happen to her ability to exercise, but her respiratory system would not work as hard, since glucose has more energy than oxygen molecules.
D. Nothing would happen to her ability to exercise, but her digestive system would not work as hard, since glucose is already small enough to get to her cells.
3. Doctors tested a patient and found that his cells contained normal levels of oxygen and glucose molecules, and no starch molecules. Will this patient be able to exercise normally?
A. Yes, the glucose and oxygen molecules can react together to release energy for the body to function.
B. No, his digestive system is not breaking down food molecules; his cells need starch molecules to react with glucose, which releases energy.
C. No, his body systems are working, but he needs to eat different food; in cells, only amino acids can react with oxygen to release energy.
D. Yes, as long as his cells have glucose, they don’t need anything else to release energy for the body to function
4. Some problems with the digestive system make it very difficult for the body to digest enough food. Why would it be harder to exercise when you have a digestion problem like this?
A. You would not be able to sleep, which would make you too tired to exercise.
B. Your cells would have molecules from air, but would not get enough molecules from food.
C. You would need to breathe in a lot more air because your body would have fewer molecules from food.
D. You would not get any of the molecules your cells need to exercise.

Before their game, the players on the Bears ate a lunch of mostly starch. The Panthers game was played at very high altitude, where there is less oxygen. The players on the Panthers ate a lunch of starch and protein. Which team probably did better in their game? *
A. The Bears probably did better because their cells released energy from oxygen reacting with glucose, which was broken down from starch in the digestive system.
B. The Panthers probably did better because their cells released energy from breaking down protein in the digestive system, which then combined with oxygen in cells.
C. The teams did equally well because their digestive systems just need to break down starch into glucose for cells to release energy.
D. The teams did equally well because glucose from starch can react with oxygen or proteins to release energy.

A pancreatic injury is some form of trauma sustained by the pancreas. The injury can be sustained through either blunt forces, such as a motor vehicle accident, or penetrative forces, such as that of a gunshot wound. The pancreas is one of the least commonly injured organs in abdominal trauma.
Pancreas Trauma Symptoms
>Redness and bruising may indicate the site of the injury in blunt trauma.
>Abdominal pain and back pain is common with pancreas injury although it is possible for a person to be pain free.
>Bleeding is obvious in penetrating injuries and clinical signs of significant blood loss may be present in severe cases.
The exact cause of asthma is not known; it is suspected to be due to genetic and/or environmental factors. Most commonly observed symptoms include shortness of breath, wheezing, coughing and tightness in the chest. Asthma can be controlled with medications.
Symptoms of asthma vary from person to person:
>Most common symptoms of asthma are dyspnea or labored breathing, audible wheezing, tightness of chest and persistent coughing
>Patients usually exhibit very low systolic blood pressure and abnormally rapid breathing during an attack
>Wheezing sounds may accompany both inspiration and expiration or expiration alone
