Bacteria

Explanation:

Nitrification fixation takes place by nitrogen-fixing bacteria like Azotobacter, Klebsiella, Bacillus etc which convert atmospheric nitrogen gas into fixed-nitrogen compounds like nitrates or ammonium ions for the plants to readily absorb.

The nitrogen fixing bacteria can be free-living like cyanobacteria or live with symbiotic relationship with plants and fungi.

The chemical conversion of di-nitrogen to ammonia takes place with the help of enzymes like nitrogenase in combination with leghahemoglobin, a protein through a reduction reaction.

Speculate as to how the information obtained from the sequencing of the human genome might be used to someday eliminate inborn e
Katena32 [7]

Answer:

Explanation:

Sequencing the human genome is the function of the human genome project with the goal of determining the base pairs/order of DNA nucleotides that make up human genome, and also identifying and mapping all of the genes of the human genome both from the physical level and its functions in molecular medicine. The benefits in this field could allow for better diagnosis of disease, early detection of certain diseases, and gene therapy and control systems for drugs.

Inborn errors of metabolism are rare genetic (inherited) disorders where the body cannot properly digest and turn food into energy through the normal pathway. The disorders are usually caused by mutations in specific enzymes that help in the break down of these foods.

Through the study of the human genome, sequences involved in these mutations giving rise to these disorders are identified and mapped to their variuos locations. This can help in the early diagnosis of the disorders and effective control system for drugs and gene therapy against these disorders.

Most cells fall within the range of 5-20 microns. What factors keep the size of the cell within these boundaries?
Tema [17]

Answer: Cytoplasm and organelles

Explanation:

Normally, a cell cannot attain a size greater than 20 microns due to the limits imposed by the size inter-relationships of its components. For example, there is a relationship between the amount of nuclear material and the size of a cell; this limits cells to a size where there is an optimal proportion of nuclear material to the rest of the cell.

Hope this helps :) and can I please get a brainly

Name the type of bacteria involved in the process labelled B
Zanzabum

Picture attached

Answer:

Nitrifying bacteria

Explanation:

The process labelled B is the conversion of inorganic nitrogen from organic products to atmospheric nitrogen. This process is called denitrification.

Denitrification is a process where nitrate is reduced to molecular nitrogen  through a series of intermediate products. This processed is carried out by bacteria called denitrifying bacteria.

Denitrifying bacteria are an important part of the nitrogen cycle.
