The correct answer is Agronomy.
Agronomy is a branch of agriculture science which deals in crops and the related soils. It is actually integration of many sciences. How to grow crops effectively and profitably without damaging environment and judicious use of natural resources are dealt in agronomy. Agronomy also develops techniques for the better use of soil and increase the food production.
The correct answer is: The virus has entered the genome of the bacterial cell and is in the lysogenic stage
Lytic cycle and lysogenic cycle are types of a bacteriophage’s life cycle.
Lytic cycle can be divided in stages:
• Attachment-viruses binds to the receptor on the surface of bacterial cell, usually it uses tail for the attachment
• Entrance-virus injects its genome material (DNA or RNA) into bacteria cell
• Replication and protein synthesis-virus uses mechanism of bacteria to replicate its genome and produce proteins. As a consequence, a huge number of new viruses are formed
• Lysis- viruses express protein for the bacterial lysis (bacterial cell expand and burst) and hundreds of new phages are released.
Lysogenic cycle is different: bacteriophage’s genetic material-prophage, integrates into the host bacterium's genome or forms circular replicon in the bacterial cytoplasm. Bacterium continues to live and reproduce normally but prophage can be transmitted to daughter cells.
Thymine, is the answer you’re looking for.
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
