Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate.[5] Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis.
It is mRNA because RNA, which stands for ribonucleic acid, is a polymeric molecule made up of one or more nucleotides. ... During the process known as transcription, a RNA copy of a segment of DNA, or messenger RNA (mRNA), is made. This strand of RNA can then be read by a ribosome to form a protein.
Answer:
The root and shoot systems facilitate the ability to absorb, CO2, light, water, and minerals. The root system consists of the roots, and the shoot system consists of the stems and leaves. Angiosperms and vascular plants rely on these two systems. Roots are nonphotosynthetic and starve unless photosynthesates are absorbed through the shoot system. The shoot system depends on the roots to absorb nutrients.
