In gilled mushrooms, gills are used to maximize spore production. Gills of some mushrooms are folded and crowded to obtain maximum spore production. Other gills, spread towards the outer cap which gives way to new gill growth in between gills which is called partial gill. Some of the mushrooms grow gills in layers too.
Answer:B6 and B12.
Explanation:
Homocysteine is an amino acid produced from demethylation of methionine.The later is an amino acid needed in the body which must be conserved.
In order to conserve it ,Homocysteine is recycled in a specific pathways which inovles activities of Vitamin B6 and B12
.Therefore deficiency of these vitamins leads to elevated levels of Homocysteine.
HIGH LEVELS OF HOMOCYSTEINE AFFECT THE ENDOTHELIAL CELLS ;LEADING TO ABNORMAL CLOTTING OF BLOOD.THIS INCREASE IN BLOOD VISCOSITY PUT THE HEART AT RISK OF CARDIOVASCULAR DISEASES.
1. Virus attaches to the bacterium
2. Virus injects into the bacterium

4. Compounds of the viral proteins coat are reproduced from genes in the viral DNA
5. Viral particles self assemble into new viruses
6.Viruses burst out, killing the host cell

Answer: 1,2 and 3.
The following are common to transformation, transduction and conjugation.
1. Unidirectional transfer of genes.
2. Incomplete gene transfer.
3. Homologous recombination.
Explanation:
Transformation is the taking up of free DNA from the environment.
Transduction is the transfer of DNA by bacteria to a viruses.
Conjugation is the transfer of Plasmid or circular DNA through a tube between the cells. Incomplete DNA are transferred unidirectional .
