Answer:

Some types of coliform bacteria can cause death if ingested.

Explanation:

We have coliform bacteria as part of our bacterial flora. Most coliform bacteria are not harmful. However, there are some strains such as E. coli (Escherichia coli) that can cause serious diseases.

What is the primary function of the juxtaglomerular complex?
Vsevolod [243]

Answer:

Juxtaglomenular is a structure in the kidney which regulates the function of each nephron, the functional units of the kidney. The main function of the  juxtaglomerular cells is to secrete renin in response to:

Stimulation of the beta-1 adrenergic receptor

Decrease in renal perfusion pressure (detected directly by the granular cells)

Decrease in NaCl concentration at the macula densa, often due to a decrease in glomerular filtration rate

Explanation:

The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and a structure in the kidney that regulates the function of each nephron, the functional units of the kidney.

How might a change in pH levels affect enzyme reaction rate and shape in the cell
babunello [35]
Enzymes are highly specific proteins that function best at certain pHs. A change in pH would affect its structure; too high or too low would cause denaturation. When this happens, the enzyme won’t have the correct structure to function as a catalyst. Therefore, reaction rate will slow.

Hope this helps!!
