Answer:
This question lacks options but the sequence follows this pattern: DNA ---> RNA ----> Protein
Explanation:
DNA is the stored form of the genetic material in living cells. It contains the genetic information needed by an organism to function. However, this information needs to be decoded and expressed. The cell does this by employing two major processes: transcription and translation. Transcription is the process whereby the information in the DNA is used to synthesize a RNA molecule.
The RNA molecule is specifically called a messenger RNA (mRNA) which is formed by copying the information in the nucleotide sequence of the DNA into it using complementary base pairing. The next process after the mRNA has been synthesized is to use the mRNA as a template to direct the synthesis of amino acids, which are building blocks of proteins. The mRNA sequence is read in a group of three nucleotides called CODON. Each CODON specifies a particular amino acid.
The sequence of the mRNA is read in the ribosome (organnelles of Protein synthesis). Each CODON read means the addition of one amino acid to the polypeptide chain. The order of the amino acid sequence determines the PROTEIN that is formed.
In a nutshell, the order of sequence in the DNA is used to synthesize a mRNA. The order of sequence in the mRNA is used to synthesize an amino acid sequence. The order of amino acid sequence determines the PROTEIN. Hence, DNA does not make proteins directly but is a recipe for its production.
Answer:
brush border cells....!!
The simple cuboidal cells of the proximal tubule are referred to as Proximal Convoluted Tubule (PCT) cells.
They have a distinct feature of having prominent microvilli on their luminal surface that forms a brush border.
These microvilli contribute to creating a large surface area which facilitates the maximization of the absorption and secretion of solutes including Na+, Cl¯, glucose, among others - a key function of this portion of the nephron.
These cells are responsible for the active transport of ions across their membranes and hence they possess a high concentration of mitochondria to produce sufficient ATP.
The PCT cells, forming a simple cuboidal epithelium, are active in secretion and absorption of molecules.
They are observed in the lining of the kidney tubules and are critical to the kidney's filtration function.

2. composite
3. cinder cone
a very tall and broad-sloped peak made of mostly lava flow
a very tall, steep-sloped peak made of both lava and volcanic materials
a shorter peak made of ash and volcanic rock
1. Shield -a very tall and broad-sloped peak made of mostly lava flow
2. Composite- a very tall, steep-sloped peak made of both lava and volcanic materials
3. Cinder cone- a shorter peak made of ash and volcanic rock
Volcanic mountains: Shield: A very tall and broad-sloped peak made of mostly lava flow, Composite: A very tall, steep-sloped peak made of both lava and volcanic materials, Cinder cone: A shorter peak made of ash and volcanic rock.
Volcanic mountains are formed through volcanic activity, where molten rock, gases, and ash are ejected from a vent or opening in the Earth's crust.
When lava flow and make a very tall and broad-sloped peak-like structure, then it is known as a shield. When a very tall and steep-sloped peak structure is made of both lava and volcanic material, it is called a composite. When ash and volcanic rock make a shorter peak, then it is called cinder.
