It aids in the maintenance of healthy immune function in kids and may reduce the frequency of mild upper respiratory tract infections. Calcium keeps the bones healthy and teeth thus supporting the skeletal structure and function. Iron is an important component of hemoglobin.
The correct answer is - That some force lifted the rocks from the water.
The fact that there's sedimentary rocks on the tops of the mountains is an evidence that there has been some force that managed to lift upwards parts of the seafloor. Taking into consideration how slowly this force manages to lift up parts of the Earth, we can easily assume that the Earth is very old. The amount of time that is needed for a part of the seafloor to be lifted few thousand meters upwards is counted in tens of millions of years, thus giving us evidence that the Earth has been around for a very long time.
Answer:
The correct answer is - (B) As with any living thing, a plant has an optimal temperature range at which it grows and performs best.
Explanation:
Like any other or most of the living organism, plants also required an optimal temperature range as they also required appropriate temperature for their growth and development and perform their functions at their best.
Optimum temperature range is a temperature range at which something performs its best similarly plants perform their cellular functions like photosynthesis, metabolism, reproduction, and many other functions that require a particular temperature range.
The correct answer is option C, For more kingdoms were introduced
Linnaeus was the first to develop a system of classification of living things. He mainly grouped the living things into animal or plant kingdom, but later with the advent of microscope it became easy for the researchers to observe microscopic beings and thus three new kingdoms were proposed namely- fungi, protists (considered as simple organism) and monera (bacteria).
Not only this with in a kingdoms comes several phylum, these phylums were also reorganized and recategorised based on the discovery of more categories and subcategories.
