Answer:
The rock containing clinopyroxene and plagioclase (a type of feldspar) is called either basalt (fine grained extrusive rock) or gabbro (coarse grained intrusive rock). The plagioclase is generally calcium rich i.e. anorthite rich. But rock contains sodium rich feldspar. This means the sodium has replaced calcium. This replacement occurs in underwater (in oceans/seas) extrusion of basalt where sodium from seawater replaces the calcium in anorthite rich plagioclase feldspar. The altered basalt due to sodium exchange is called spilite which contains sodium rich feldspar and pyroxene.
Explanation:
The atomic mass of an element tells us the sum of protons and neutrons in it.
Therefore, option A is correct.
b. Cell membrane
Explanation:
Homeostasis is a set of conditions where an organism will function best. Every organism works hard in order to attain homeostasis and cell membranes play an important part in maintaining homeostasis.
The function of a cell membrane is to control the materials of coming in or out of the call. The cell membrane decides if that specific material will enter the cell or not based on the optimal concentration level.
Explanation:
DNA: 3'-5' - ATC GCC CGT
mRNA: 5'-3'- UAG CGG GCA
RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes; RNA codons determine certain amino acids, so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Guanine, Cysteine and Uracil). Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.
Nucleic acids like DNA stores all of an organism’s genetic information. Nucleic acid molecules comprise the nitrogenous bases Guanine, Adenine, Cytosine and Thymine. Conversely, RNA nucleotides are Adenine, Guanine, Cysteine and Uracil. These pair up as base pairs due to their varied structure- largely influenced by the location of N molecule.
In certain combinations, these bases form codons which act as instructions for protein synthesis. Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis. Thus, these contribute to the broad diversity of living organisms, as varied combinations of these 64 codons can produce many proteins which can be organized into cells, tissues and organisms.
