Answer: Lets choose a food processing company for scientific study.
Explanation:
Scientific study is the study which involves taking observations on the samples being studied experimentally. Drawing evidences from observations to prove a scientific fact.
In a food based company, several scientific tests are required to be done to check the shelf-life, quality, quantity of the ingredients, and to check whether they are fit for consumption or not all of these parameters have to checked through experimental procedures.
The scientist that thought he had proven that plants obtain their nutrients from water rather than soil is Van Helmont.
Chromosomes are thread-like structures in which DNA is tightly packaged within the nucleus.
Answer:
The correct answer will be option- B.
Explanation:
Synovial fluid is a clear slippery fluid which is present in the synovial cavity.
The synovial fluid helps the nourishment as it provides nutrients to the and oxygen to the hyaline cartilage of the bones as well as the lubrication of the cartilage surfaces due to the viscous nature like oil which lubricates the piston.
This smooth surface facilitates the smooth and painless movements between the bones, therefore, the Option-B is the correct answer.
Lunar maria (plural form of the Latin word mare, which means sea) are dark surfaces that can be found all over the moon (17% of the Moon is covered in them) that have been created as a result of volcanic eruptions. These areas are made up of basalt, and given that they seemed almost waterlike, the astronomers in the distant past mistook them for seas, whence their name comes.
When it comes to craters, their origin is quite similar - volcanic eruptions created them. When lava starts erupting from a volcano, it has to get out from somewhere - and thus craters are created. If you are referring to lunar craters, however, there are many speculations as to how they were created: due to volcanic eruptions, meteoric impact, or glacier activity.
