Cells are often ground up with abrasive to get to their internal enzymes/molecules, followed by removal of the abrasives. Here a
AlladinOne [14]

Answer:

Option (1).

Explanation:

The RNA is produced from the DNA by the process known as translation. The proteins products are produced from the RNA by the process known as translation. Proteins are the polymers of the amino acids.

The situation 1, radioactive amino acids has been used. In this case, the mRNA is used in this process to make the radioactive proteins by the process of translation. The radioactive amino acids are used for the formation of radioactive protein. The situation 2, the RNAase has used with radioactive amino acids. In this case, the RNAse enzyme breaks the mRNA molecule and the proteins are not translated that contains the radioactive amino acids. No proteins formation occurs in this case.

Thus, the correct answer is option (1).

vekshin1

Answer:

The two components that helps to maintain the homeostasis of the cell are 1  Buffer system 2 Membrane transport process

Explanation:

1 Buffer system Buffer system helps to maintain a constant PH in addition to small amount of acid or base .There are many buffer system present inside  our body

A Bicarbonate buffer system helps to maintain concentration of carbon di oxide, bicarbonate ion and Carbonic acid according to our body"s need.

B Phosphate buffer system

C Hemoglobin buffer system This buffer system helps too maintain normal O2/CO2 ratio of our body which is very much important of maintain our body"s homeostasis.

2 Membrane Transport process  Various ion channels of plasma membrane sych as Na+ K+ ATPase,Ca2+ATPase ,H+ ATPase helps maintain ionic homeostasis of our body.

Carl Woese distinguished between the members of the archaea and the bacteria using studies of their ribosomal RNA.

What is ribosomal RNA?

Ribosomal RNA (rRNA), a particle in cells that are sent out to the cytoplasm and is a part of the protein-creating organelle known as a ribosome, supports the change of courier RNA (mRNA) into protein. Moreover, ribosomal ribonucleic corrosive is a type of non-coding RNA that fills in as the primary structure block of ribosomes, which are essential for all cells. Protein combination is done by rRNA, a ribozyme, in ribosomes. In spite of never being converted into proteins, it makes up around 80% of cell RNA.

NacL is dissolved in water so that the concentration is initially higher in one part of the water the other,______ will occur so
mixas84 [53]
NaCl is dissolved in water so that in a given region or volume the concentration is initially higher in one part than the other l, thus simple diffusion will occur so that there is a net difference or 0, with respect to the concentration of NaCl in a particular volume of water than another. Basically the NaCl will be distributed throughout volume of water.
