Answer:
The percentage of space not occupied by solid matter in soil is called :
B. Porosity.
Explanation:
- Porosity is represented as the percentage of void in the soil.
- In simple words, it is the number of pores present in a soil.
- The porosity of soil is a factor that determines the quality and suitability of the soil for agriculture.
- A more porous soil does not hold lot of water and nutrient while a less porous soil retains water and nutrient.
- Thus neither a extremely porous nor a less porous soil is suitable for agriculture.
Answer:
Protein synthesis consists of a series of steps ranging from the transcription of DNA to messenger RNA (mRNA), to the coupling of this to transfer RNA (tRNA) and ribosomes to produce polypeptide chains by the addition of amino acids.
Explanation:
DNA is a molecule present in the nucleus of the cell, formed by a double <u>complementary strand</u> that is linked by specific sequences of nitrogenous <u>base pairs</u>. This sequential order contains the organized genetic information of a species.
- The first step in protein synthesis occurs in the nucleus, through the transcription of DNA into mRNA, in which a single strand of mRNA is formed from the sequence of nitrogenous bases, with the help of the enzyme RNA polymerase. This transcription also includes the synthesis of <u>tRNA</u> and ribosomal RNA. Transcription occurs in the 5' → 3' direction of the DNA strand.
- Once the different RNA molecules have been synthesized, the next step occurs in the cell's cytoplasm, with the binding of the mRNA to the minor subunit of the ribosome. In the sequence of nitrogenous bases in mRNA, a triplet of bases is called a <u>codon</u> -the base of the genetic code- each of which will encode a specific <u>amino acid</u>.
- To the complex formed by mRNA and minor subunit of the ribosome a tRNA is coupled, which contains the <u>anticodon</u> that determines this coupling, in addition to the amino acid it encodes. This is the moment when the major subunit of the ribosome is attached and protein synthesis begins.
Each of the amino acids will be linked to others by peptide bonds -following the sequence of codons in the RNA- until synthesis stops with the appearance of the stop codons.
Hydrogen gas is the answer.
Pls mark as brainliest
A. tertiary consumer. just kinda count out, first thing, if a plant is a producer, then consumer, secondary consumer, tertiary, so on so forth
The “S” phase which is the phase of DNA synthesis
