<span>C. Experimental group
</span><span>
Basically the experiment has to be done with proper reasoning to make the scientific explanation satisfactory for all concerned. Scientific method is a process that is ongoing. Based on the observations via properly done experiments, a scientist can come to a proper conclusion. Although the procedures followed during experiment may vary, but the final result should always be the same. </span>
Answer: 1. mechanical weathering
2. Soil
Explanation:
1. Some animals such as moles dig which breaks down rocks underground.
2. Soil is different amounts of broke down particles some still have big particles like sand while others are really fine like clay.
<span>There are three RNAs with a role in the synthesis of protein.</span>
mRNA, or messenger RNA, is the link between a gene and a protein. The main role of this ribonucleic acid is in transcription (”reading“) of DNA. The DNA is transcribed by RNA polymerase, and the resulting product of this process is mRNA. This form of RNA can be modified post-transcriptionally with methylguanosine caps and polyadenosine tails. RNA carries the genetic information which is copied from DNA and the information has a form of three-base code (“words”), codons. Each of these codons specifies a particular amino acid.
tRNA or transfer RNA is the molecule with the main function in translation by "decoding" the mRNA message during this process. Each type of amino acid has its own type of tRNA and also has a three-base sequence (anticodon) that can bind complementary with the codons in the mRNA.
rRNA or ribosomal RNA is a main component of ribosomes. rRNA associates with a set of proteins to form ribosomes which catalyze the assembly of amino acids into polypeptide chains (protein).
<span>There are also a few more types of RNA which have a regulatory function like, microRNA or siRNA.</span>
RNA, in one form or another, touches nearly everything in a cell. RNA carries out a broad range of functions, from translating genetic information into the molecular machines and structures of the cell to regulating the activity of genes during development, cellular differentiation, and changing environments.
