Vinil7 [7]

Answer:

1.31 cM

Explanation:

Total offspring = 2205

Since two genes are involved, F1 progeny should have four types of combination. Out of them two are 17 and 12 which definitely means they are in lesser number. Since recombinants are always less than parental progeny in linkage, the given two types are recombinants.

Recombination frequency = (Number of recombinants / Total progeny) * 100

= [ ( 17 + 12 ) / 2205 ] * 100

= ( 29 / 2205 ) * 100

= 1.31 %

Map distance = Recombination frequency

Hence, distance between two genes = 1.31 cM

How to use bacteria as a treatment for sewage waste
algol [13]

Answer: hope this helps

Explanation:

Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process.
