C. 1,2,1,2 
 
1 CH4+ 2 O2= 1 CO2+ 2 H20.

when balancing, you need to make sure that each side has the same number of each atom. The reason for this is to abide by the law of conservation of mass; essentially you can't have more or less than you put in the equation. 

When you put the coefficients of C. into the equation you have a total of 2 carbon atoms on each side, 4 hydrogen atoms, and 4 oxygen atoms.

Answer: Classic seminoma

Explanation:

The classic seminoma can be defined as the germ cell tumor of the testicles or mediastinum. It is a type of malignant neoplasm and is treated and curable stage of the cancer.

It has a survival rate of more than 95 % if it is detected during the early stages of diagnosis.

It originates in the germinal epithelium of the semniferous tubules. In this case the fertility of the person is not affected and sexual function also remains intact.

Use the numbers to put the steps of translation in order, from first (1) to last (5). The large ribosomal subunit completes the
pashok25 [27]
Translation is a complex process that translated the genetic information from the language of DNA in the language of RNA. The first step in this process is the binding of the initiator tRNA (that is bound to the aminoacid methionine) to the small ribosomal unit. Then, the small ribosomal unit joins the mRNA; it is the part of the ribosome mainly responsible for translating. After that, the initiator tRNA binds to the start codon. This reaction frees some initiation factors that make large ribosomal units bind to the small one. Hence, <span>the large ribosomal subunit completes the initiation complex afterwards. The role of the large ribosomal unit is mainly to make the peptidic bonds between the aminoacids in the new protein. After that, </span><span>amino acids are paired with anticodons, gradually forming a long chain</span>; this chain is called a polypeptide and is the skeleton of the protein that is created. Finally, this process stops when one of the three possible stop codons are reached.
