D, hydrotrophism.
the word gives the answer away because Hydro is a word meaning water
Answer: Mendel would have concluded that one pair of factors (genes) is responsible for two different characters in plants.
Explanation:
The 9:3:3:1 ratio observed by Mendel helped him to form his <em>Law of Independent Assortment </em>which states that the inheritance of one pair of factors (genes) is independent of the inheritance of the other pair.
Also from his previous studies, he obtained a 3:1 ratio for a single gene expression, flower color, which enabled to form <em> the Law of Segregation</em>, which states individuals possess two alleles and a parent passes only one allele to his/her offspring.
However, if he had observed a 3:1 ratio for two traits, he would have concluded that inheritance of characters occurs in pairs i.e., that a pair of alleles is responsible for two different characters in plants.
A. Lysogeny.
B. Lysogenic conversion
C. Temperate phages
D. Induction
E. Prophage
Explanation:
Lysogenic replication or lysogeny is the process of a bacteriophage invading the host’s cell, grows, replicates for generations, multiply by undergoing lysis in the host’s cell.
The basic steps of lysogenic or lytic life cycle are:
- Attachment of the phage with the host’s surface
- Penetration of the DNA to the host’s cell
- Biosynthesis of phage protein through replication of phage DNA
- Maturtion and assembly of phage particles
- Lysis to release new phages
Apart from these, under certain conditions, lysogenic replication can occur by:
Lysogenic conversion where the phenotype of a normal bacterium is converted and becomes pathogenic and produces harmful proteins and cause diseases
Other phages which can undergo lysogenic replication cycle are called temperate phages
Prophage is a type of bacteriophage which is inactive but remains in the chromosome of the host cell which powers the bacterium to be resistant to infections caused by other viruses.
Induction is the process of excision of the phage from the host’s chromosome through physical or chemical methods.
The first answer is correct.
A group of closely related organisms that can produce viable or fertile offspring.
