Answer:

The correct answer is C electron transport chain produces more ATP than glycolysis or the krebs  cycle.

Explanation:

Glycolysis ,krebs cycle and electron transport chain all are the principle steps of cellular respiration.

 During glycolysis  4 molecules of ATP is produced and 2 molecules of NADH is generated

 During krebs cycle 2 molecules of GTP  which is equivalent to 2 molecules of ATP is produced along with 6 molecules of NADH and 2 molecules of FADH2 are produced.

During electron transport chain the 8 molecules of NADH of glycolysis and krebs cycle and 2 molecules of FADH2 of krebs cycle undergo oxidation to form 26 molecules of ATP.

If a bacterial cell culture contains 2 cells at time zero, 8 cells one hour later, 32 cells after 2 hours, and 128 cells after 4
elena-s [515]

Answer:

B) g = 0.5 h, v = 2 h^-1

Explanation:

Generation time is the time taken for a bacterial cell to divide and produce an offspring. Bacterial cells divide exponentially.

The total number of cells is given as =2n x initial number

[n = number of generations]

So if the total is 8 cells:

8=2n x 2

2n=4

n=2

That means 2 generations have arose

Generation time is given as \frac{t}{n}

where t=the time taken

if t=1hour and n=2

Generation time = \frac{1}{2} = 0.5hour

Generation time, g =0.5h, and the rate of generation (growth rate), v is 2 per hour

Describe the structure of the kidney and include structure of nephron as well
asambeis [7]

Answer:

Generally, mammals have a pair of bran-shaped kidneys. The mammalian kidney has 2 distinct regions, an outer renal cortex and inner renal medulla. Both regions are packed with microscopic excretory tubules, nephrons, and their associated blood vessels. Each nephron consists of a single long tubule and a ball of capillaries, known as glomerulus. The blind end of the tubule forms a cup-shaped swelling called Bowman’s capsule, that surround the glomerulus. From Bowman’s capsule, the filtrate passes through 3 regions of the nephron which are proximal tubule, the loop of Henle. A hairpin turns with a descending limb and an ascending limb and the distal tubule. The distal tubule empties into a collecting duct, which receives processed filtrate from many nephrons. The many collecting ducts empty into the renal pelvis, which is drained by ureter.

For the structure of nephron, each nephron is supplied with blood by an afferent arteriole, a branch of the renal artery that subdivides into the capillaries of the glomerulus. The capillaries converge as they leave the glomerulus, forming an efferent arteriole. It is surrounded by the Bowman’s capsule. The double-walled epithelial Bowman’s capsule is formed by the invagination of the blind end of the nephron. The glomerulus and Bowman’s capsule form the first region of the nephron and is known as the renal corpuscle or the Malpighian body. The capillary walls are composed of a single layer of endothelial cells with openings between them with a diameter 50-100nm. These cells are pressed up against basement membrane which completely envelops each capillary, separating the blood in the capillary from the lumen of Bowman’s capsule. The inner layer of the Bowman’s capsule is composed of a cell called podocytes which have arms that give off structures resembling tube-feet called foot processes or secondary processes. The secondary processes support the basement membrane and capillaries beneath it and gaps between the processes (slit pores) facilitate the process of filtration. The Malpighian body leads into the remainder of the tubule.
