First one to answer gets BRAINLEIST! :D

Answer:

Experimental groups: type of dogs

Dependent variable: hearth rate

Independent variable: the amount of caffeine  

Explanation:

The dependent variable is the variable being measured or tested in a given study, while the independent variable isn't changed by the other variables. In this case, the heart rate is dependent on the amount of caffeine, which is then the independent variable. The experimental groups are the groups exposed to the independent variable.

Explanation:

Answer:

Stereoscope

Explanation:

Stereo Microscopes enable 3D viewing of specimens visible to the naked eye.

Assuming you meant melts and not ments (if it was the latter, I have no idea what you mean), the answer is False. The melting point is when the substance melts, turning from a solid to a liquid. On the other hand, the boiling point is when the substance turns from a liquid to a gas.

Answer:

El efecto del material sobre el medio ambiente es el aspecto a considerar.

Explicación:

Se debe verificar la estructura química del material o de qué elementos se forma un material para conocer el efecto de estos materiales en la salud y el medio ambiente de las personas. Si los materiales no afectan el medio ambiente y la salud humana, el ser humano puede utilizarlos para satisfacer sus necesidades. Si el material se forma a partir de elementos tóxicos o elementos que no se descomponen por microbios, entonces este tipo de materiales son peligrosos tanto para la salud humana como para el medio ambiente porque estos materiales contaminan el medio ambiente y debido a esta contaminación la salud humana se ve gravemente afectada.

Answer:

In wells Scientist measure dissolved oxygen, or DO (pronounced dee-oh).

The kind of thing that might scientist measure in a mine or well is the amount of dissolved oxygen. It is also named DO.

Scientists are widely responsible for conducting and communicating scientific works on the basis of their respect, integrity, fairness, transparency, and trustworthiness. They always considered the consequences of new knowledge and its application.

According to the context of this question, scientists perform their role for the betterment of society, reliability, and efficiency of human beings with full concentration.

The amount of dissolved oxygen delivers the significance of nutrients present in a well or mine. Scientists conduct and gather research perspectives in order to gain knowledge in a particular area.

Therefore, the kind of thing that might scientist measure in a mine or well is the amount of dissolved oxygen.

Explanation:

Measuring devices are used as follows -1. Thermometer, 2. Heart monitor, 3. Measuring cylinder, 4. Clock, 5. Tape measure

The instruments that are used for the measurements of various specific items based on the laws and the theories of measurement are called measuring devices.

Specific measurements have specific measurement devices. These measure the value based on the specific unit of the measurement.

For example, an inch tape measures the length of something in inches. It also has scales of centimetres and meters.

For the measurement of length, scales and tape measures are used.

For the measurement of time, clocks are used.

For the measurement of volumes, graduated cylinders are used.

For the measurement of temperature, thermometers are used.

Therefore, the measuring devices vary according to the function it needs to perform. In this case, 1. Thermometer, 2. Heart monitor, 3. Measuring cylinder, 4. Clock, 5. Tape measure.

Hydrophobic substances such as vegetable oil are nonpolar substances that repel water molecules.

Nonpolar substances are molecules that do not have a charge separation between different parts of the molecule. This means that they do not have a polar, or electrically charged, end, and as a result, they do not dissolve well in polar solvents like water.

Nonpolar substances are hydrophobic, meaning that they repel water molecules, and tend to dissolve in other nonpolar substances, such as oils and fats. Examples of nonpolar substances include hydrocarbons like gasoline, fats, oils, and waxes, as well as some gases, like nitrogen and methane. Nonpolar substances play an important role in a variety of biological and industrial processes, and their unique properties make them useful for many different applications.

Answer:

Titín is the largest know protein with the greatest number of animo

The largest known protein with the greatest number of amino acids is titin.

Titin or connectin  is a largest protein  in humans which is encoded by the TTN gene, having greater than 1 µm in length and it functions as a molecular spring  responsible for the passive elasticity of muscle.

It consist of 244  folded protein domains connected by unstructured peptide sequences, when the protein is stretched, the domains will unfold.

Titin protein involve in the contraction of striated muscle and connected  the Z line to the M line in the sarcomere, contributes to force transmission at the Z line.

It limits the motion range of the sarcomere during tension,  so it involve in the contribution of  passive stiffness of muscle, it is the third most abundant protein in muscle after myosin and actin.
