What are measuring devices?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.

Explanation:
Individuals do not evolve as a result of natural selection over successive generations. Populations evolve ONLY as certain traits become more common and others go away.
Answer:
False
Explanation:
Singular living beings don't evolve, they hold similar qualities for an amazing duration. At the point when a populace is advancing, the proportion of various hereditary sorts is evolving. Hope this helps!
You have planted corn in a field with clay soil. The field is predominantly flat with a slight slope at one end where a creek borders the field. You notice that germination and growth is slowest in the flattest portion of the field. Conversely, you also notice that you received good germination and rapid growth on the slight hill which meets the creek. You wonder why there should be differences in growth and germination in different parts of the field. Is it due to the extra water near the creek? Is there something different about the soil in that portion of the field, or is it due to the difference in slope (north, south, east, and west). 1. What is your hypothesis for this problem? 2. Design an experiment to test the hypothesis you have written (make sure you include a procedure [step by step list of what you will do], an IV, a DV, treatments, trials, and constants).
Hypothesis: The soil in the flat part of the field has less fertility than the soil on the small hill.
Experiment:
The experiment will be carried out in a greenhouse, to promote a controlled environment and equal to all plants used in the treatment.
In this experiment, the influence of the difference in fertility of the soil samples, in the flat part of the land and in the most inclined part, in the germination and growth of corn plants will be tested.
Corn seeds of the same species will be selected. All seeds will be sanitized and will go through the same dormancy breaking process, so that all of them have their germination stimulated.
Vessels with a capacity of 30 kilos will be caught. These pots will be cleaned, sterilized and filled with the same amount of soil collected in the field and with two corn seeds. It will be used 10 pots with soil that was collected in the flat part of the land, 10 pots with soil from the sloping part of the land and 10 pots with fertilized substrate containing high levels of fertility.
The pots will be placed in a greenhouse and will be irrigated with distilled water, to avoid contamination by possible substances in the water.
The pots will remain in the greenhouse for 100 days, where the behavior of seeds and plants in each of them will be observed and noted. After this period, a comparison will be made between the vessels of each treatment, assessing the differences between them and reaching the conclusion whether the hypothesis is true or false.

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.
What 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.

A student wants to test the effect of different amounts of caffeine on the heart rate of dogs. Describe the experimental groups in this experiment. What is the dependent variable? type of dogs amount of caffeine the heart rate number of dogs
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.

The boiling point of a subtance is the point at which the subtance ments.
A) True
B) False
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.

nonpolar substances that have an attraction for water molecules.
O polar substances that repel water molecules.
O polar substances that have an affinity for water.
Hydrophobic substances such as vegetable oil are nonpolar substances that repel water molecules.
What are non polar substances?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.
