We need options :) but stem cells are a amazing type of cells that are able to develop into many different types of cells <span>First, they are unspecialized cells capable of renewing themselves through </span>cell division<span>, sometimes after long periods of inactivity. Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions.</span>

______ make their own food by extracting compounds from the ocean.photoautotrophs,chemoautotrophs,cyanobacteria
Nezavi [6.7K]
<span>Both photoautotrophs and chemoautotrophs synthesize organic compounds from (inorganic) carbon dioxide, a process known as carbon fixation. Photoautotrophs get the energy to perform these reactions from light. Chemoautotrophs get it from electron donors such as hydrogen sulfide and ammonia. Cyanobacteria, by contrast, convert nitrogen from the atmosphere into ammonia, a process known as nitrogen fixation.</span>

Mia conducted a five hour experiment. She used a liquid solution. The solution decreased by 9/8 ounces every hour for 5 hours. A
sasho [114]

Given:

The solution decreased by \dfrac{9}{8} ounces every hour for 5 hours.

Remaining solution at the end of the experiment = \dfrac{99}{8} ounces.

To find:

The initial amount of solution.

Solution:

Let the initial amount of the solution be x.

The solution decreased by \dfrac{9}{8} ounces every hour for 5 hours.

Total decreased amount  =\dfrac{9}{8}\times 5

                                          =\dfrac{45}{8}

Initial amount = Remining amount + Decreased amount of solution.

x=\dfrac{99}{8}+\dfrac{45}{8}

x=\dfrac{99+45}{8}

x=\dfrac{144}{8}

x=18

Therefore, the initial amount of solution is 18 ounces.

A red blood cell placed in a hypertonic solution will shrink in a process called crenation. A red blood cell placed in a hypoton
-BARSIC- [3]

Answer:

The correct answers are A. "crenation", B. "hemolysis", C. "hemolysis", D. "crenation" and E. "neither will occur".

Explanation:

0.9% (m/v) NaCl or 5.0% (m/v) glucose are isotonic solutions at which the cells will not suffer any harmful consequence. A solution with a higher concentration than the isotonic conditions would result in the cells crenation, while a solution with a lower concentration would result in the cells hemolysis. Therefore the consequences of putting the red cells to the solutions stated in the question are as following:

A: 3.21% (m/v) NaCl Solution  = crenation (higher than 0.9% (m/v) NaCl)

B: 1.65% (m/v) glucose Solution  = hemolysis (lower than 5.0% (m/v) glucose)

C: distilled H2O Solution  = hemolysis (lower than 0.9% (m/v) NaCl or 5.0% (m/v) glucose)

D: 6.97% (m/v) glucose Solution  = crenation (higher than 5.0% (m/v) glucose)

E: 5.0% (m/v) glucose and 0.9%(m/v) NaCl = neither will occur (equal to 5.0% (m/v) glucose and 0.9% (m/v) NaCl)

What do the rib muscles and diaphragm have in common?
Hatshy [7]

Answer:

Both are breathing muscles

Explanation:

When rib muscles and the diaphragm contract they increase the volume of the chest cavity, increasing the air pressure outside the body, causing air to rush into the lungs to fill the vacuum created by the increase in volume.
