protect the cell against predation?
Biology

Crank3 years ago
7 0

If your choices are the following, then the correct answer is C:

a. The aerobic bacteria were able to capture the sunlight and generate sugars from it.

b. The aerobic bacteria helped protect the cell against desiccation.

c. The aerobic bacteria metabolized sugars and generated large amounts of ATP.

d. The aerobic bacteria helped protect the cell against predation.

This is actually the endosymbiotic theory of how we humans (and other organisms alike) have evolved to have mitochondria inside our cells. Evidence to support this is that mitochondria have their own DNA different from ours.

<em>A</em> can't be the answer because that is more related to plants. <em>B and C </em>are also wrong because they simply do not provide those functions.

<span>The endosymbiotic theory states that aerobic bacteria took up residence inside these cells 2 billion years ago. These cells started producing oxygen for eukaryotic cells and are now known as mitochondria. The aerobic bacteria allowed these cells to be protected against some predators, as the cells could live in areas they once could not live in before.</span>

What are the nephrons? How are they utilized in filtration of the blood?
r-ruslan [8.4K]

What are the nephron?

Nephrons are the functional unit of the kidney. There are about two million nephrons in each of our kidneys. Each nephron has a network of glomelural capillaries called  glomerulus where blood filtration occurs, and the renal tabule which is where the filtered fluid is converted to urine.

How they work?

The nephrons act as a filter, cleaning our blood. Unwanted metabolites like urea and creatinine are taken from the blood, as well as high amounts of sodium. The filtered fluid flows from inside Bowman's capsule (epithelial cells surrounding the glomerulus) and from there into the proximal tubule (see attached figure at the end). From the tubule, fluid flows into several other ducts until it reaches the ducts where collectors will empty into the renal pelvis.
