The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants
It is the chemical properties of a substance, which determines that how the substance will react when combined with other substance.
The usual properties of a substance like density, color, and hardness are some of the illustrations of physical properties. The properties, which illustrates that how a substance modifies into a completely distinct substance are known as chemical properties.
Some of the examples of chemical properties are oxidation, toxicity, the heat of combustion, and flammability, enthalpy of formation, radioactivity, and chemical stability under particular conditions.
If a scientist sets up an experiment and the results do not support his hypothesis he should conclude that "he may want to alter some aspects of experiment and try it again".
<u>Answer:</u> Option B
<u>Explanation:</u>
Research and experimenting is all about search and re-search for achieving acceptable result in order to meet the demand of project accordingly. It demand huge patience and hard work but also smart work for saving time as much as possible.
If a scientist results do not support hypothesis than after a short break he should alter some steps or parameters of experiment and try it again. Because it may occurred due to an error. And errors are needed to be understood and then rectify it by repeating the procedures with more sincerity.
Answer:
All options are correct
Explanation:
In Lunar eclipse, Earth comes in between the sun and moon. Due to this, the sun light falls on the earth and its shadow is created that prevent the moon from shining.
In other way earth block the sun light reaching moon by coming in between the sun and moon.
Hence, All the options are correct
The correct answer is "C."
mRNA stands for messenger Ribonucleic acid. The role of mRNA is to carry genetic information for the synthesis of protein from the nucleus after transcription.
After the transcription process is over, the mRNA leaves the nucleus and heads to the ribosomes in the cytoplasm where translation of this information takes place.
The ribosomes are the work bench of the cell. They receive the mRNA with its coded information, read it and translate it and with the help of tRNA (transfer RNA), amino acids are fetched from the cytoplasm and linked together to form the exact protein that was coded for on the mRNA.
