There are 3 subjective methodes of measuring human behaviour.
1. Self-report questionnair
2. Dairy methode
3. Behavioural observation.
In my opinion Behavioural observation is the best way to measure human activity. Behavioural observation is aim to collect data about physical activity behaviour. In this methode, we can observer the beahviour of a patient or a subject during any perfomance regarding the activity, sposed by psychlogist.

Through science and technology, it is easier for inhabitants to communicate with other people around the globe. It is also significant in the field of business because transactions and other events are done through the computer. Science and technology enable every people to live an easy and modern way of life.
At the risk of being too obvious, I'm going to have to go with a vaccine and treatment for the coronavirus.
Because the plastic is the poorest conductor of heat (That means it doesn't heat up when it touches something that's hot). Metal is a great conductor of heat though, so if the handle were made of metal we would burn our hand whenever we touch the handle.
Scientists aren't entirely sure, although they're pretty positive it's genetic. For a long time, a prevailing theory was that handedness is determined by gene expression in the left or right hemisphere of the brain. However, newer research suggests that even before the motor cortex is developed, an early asymmetry in the spinal cord is actually what determines right or left handedness.
First, scientists are pretty sure the Earth's core is about 80 percent iron. How they know that is a series of educated guesses.
For starters, they can be reasonably sure of the planet's mass based on its gravitational pull. The material on the surface isn't dense enough to match up with that mass, so the rest of the Earth has to be much denser.Iron, meanwhile, is one of the most prevalent elements in the universe, but it isn't all that evident in the Earth's crust. Since scientists would expect more iron to be in our planet and it's a fairly dense element, that leads to the conclusion that the Earth's core is mostly iron. They theorize that it was pulled to the core over millions of years. By examining different seismic waves, they know that the inner part of the core is solid and the outer core is molten.
It's a lot more scientific than I've made it sound, but hopefully that gets at the gist of it.

Traditionally a balance was used to measure mass. Objects of known or accepted mass was balanced against another object of unknown mass. When the balance was level the two pans had the same mass. The term balance or scales is still used even though there is no balance used. The scales were the pans that the objects sat on.Now electronic balances are used that gauge the mass of the objects. While you can measure mass with a spring loaded scale, it is less accurate than a balance as it relies on a spring loaded to a specific acceleration of gravity for any given mass. A change in altitude will change the results given on the scale, due to the actual change in gravitational force (it is small at only about 0.031% error for every kilometer increase in altitude)*. A balance would experience no such change as the mass of an unknown quantity is compared to the mass of a known quantity, thus negating any effects of gravity.Another instrument that measures mass is an inertial balance. An inertial balance doesn't require gravity to work, so it can be used in space. It measures the mass of an object by attaching it to a spring and seeing how it affects the spring's period of oscillation.Very tiny masses can be measured directly (using a "massometer"). But we normally use scales, which measure weight, which is directly proportional to mass (a property of matter equal to its resistance to a change in speed or direction of travel). The mass of an object is the same everywhere in the universe. Its weight, however, changes depending upon its location: a Bowling ball has greater weight on the surface of the Earth than it does on the Moon. Great confusion arises when people interchange units of weight with units of mass. Scientists, particularly physicists, are very careful about not using the terms interchangeably, but regular folks have no choice for practical applications. For example, when you weigh a regulation ten-pin bowling ball, the scale will tell you it "weighs" between 4 and 7 (3.63 to 7.27 actually) kilograms, even though the kilogram is, technically speaking, a unit of mass, not weight.You can also measure the mass of an object using a scale, as long as you factor in the gravitational constant (G). For instance, in an environment with only 1/2 the gravity of That on earth, you would have to double the weight displayed on the scale to determine the actual mass. As an example, 10Kg of lead in a 0.5G environment would only "weigh" 5Kg on a scale...half as much as on earth, even though its mass is unchanged.
An aluminum cube doesn’t have a fixed density, it depends on its weight and volume. The density of a cube can be found out by measuring the object’s weight and volume and then by dividing the mass by volume. If the mass and volume of aluminum’s cube are 37.3 and 13.8, its density will be 2.7g/cm cube.

A good scientist should possess the following qualities:
1. A scientist must be curious about the world Example: Galileo Galileo's curiosity about the heavenly bodies made him the first person to use a telescope to study the moon, the sun, the planets and the stars.
2. A scientist is logical and systematic Example: Among the reasons why Gregor Mendel discovered the principles of heredity when others have failed was his logical experimental methods and his careful and accurate record keeping.
3. A scientist is open-minded and free of bias Example: An open-minded person is one who can modify plans or discard hypotheses if necessary. One such person was Johannes Kepler who was hired to develop evidence that planets moved along perfect circles.
4. A scientist is intellectually honest Example: Isaac Newton built his laws of motion on the previous work of Galileo and others.
5. A scientist works hard and is persistent Example: Marie Curie was the first person ever to be awarded the Nobel Prize twice. It was not surprising considering how hard she worked.
6. A scientist does not jump to conclusions Example: John Dalton's atomic theory was backed by experimental evidence. He was not the first to propose that the atom was the smallest particle of matter, but he was the first to use experimental evidence to support his theory.
7. A scientist is a creative and critical thinkerExample: Albert Einstein was able to derive his theory of relativity because he went beyond what was given and known at that time. He saw links and connections where others did not. He looked at things from different perspectives.
8. A scientist is rational
9. A scientist is willing to suspend judgment until he is sure of his results
10. A scientist tries new approaches to arrive at solutions
A scientist must have an open mind and be curious. It is fine to have an idea about how or why something is the way it is, but the scientist should then seek to prove or disprove this "hypothesis" and should then be willing to change their ideas depending on the results of their experiments, rather than to continue believing in their original idea even if the evidence of their experiments is sticking up against it. 1.Keen Observer 2.creative 3.patient 4.curious 5.humble 6.intellectually honest 7.objective 8.Aware of the limitations of Science 9.Persevering 10.Open minded
Water's high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.

Most commonly, a thermometer.
Thermometers are used to measure the increase or decrease in the temperature of a system as it gains or loses internal energy.
An alcohol-in-glass thermometer has been the most common personal instrument used to measure temperature. Mercury thermometers are still around but are no longer offered for sale. Today, digital devices are available that scan the forehead or ear. Some other devices used to measure temperature are:
Radiation pyrometer, for extremely high temperatures;
Glass thermometer: mercury or alcohol;
Thermistor (thermal resistor)
Platinum resistance thermometer (a resistance detector);
A mercury in glass thermometer uses mercury liquid contained within its glass structure to be subjected to heat.
the heat causes the mercury fluid to expand along the glass tube
and the total amount of expansion can be seen as a measure
along the accurate scale of indication.
This is a direct indication of the effects of temperature.
A more complex method of measuring temperature could be a
thermocouple measuring device.
A thermocouple consists of 2 dissimilar types of metal materials in the form of wires , which are joined at 1 end by weld/ fusion.
this single joined end is called the hot junction. The other end of the 2 wires are then terminated at separate junctions;
as in a electronic terminal block. This end of the 2 wires can be called the cold junction.
For most accurate temperature measure, I think temperature sensor is the first choice.
No, as snakes belong to the phylum Athropoda, whereas snails belong to the Phylum Mollusca.
