Answer:

An open system is a system that has external interactions. Such interactions can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the concept

Answer

An open system  is a system that exchanges mass and energy with its surroundings or environment.

Explanation:

IN BIOLOGY,

A cell works as an open system i.e it takes in substances needed for its metabolic activities through its cell membrane. Then it performs the metabolic processes assigned to it. Products and by-products are formed in metabolism. Cell either utilizes the products or transports them to other cells. The by-products are either stored or are excreted out of cell.

What process recharges this molecules so that it can become ATP again
alexdok [17]
<span>By rebonding with another phosphate molecule through oxidative phosphorylation, it becomes recharged and the ADP to ATP process can be restarted. This allows for more cellular energy to be produced, and more metabolic actions to be undertaken. This is the major aspect of cell respiration.</span>

Y_Kistochka [10]

Answer:

The citric acid cycle is fundamental to produce the energy needed for aerobic cell metabolism, thereby mutations in the enzymes involved in this metabolic pathway would be lethal to the individual

Explanation:

In aerobic organisms, the citric acid cycle (also known as the Krebs cycle), is a key metabolic pathway used to remove electrons and uses them in the electron transport chain in order to generate adenosine triphosphate (ATP), the energy currency of the cell. The citric acid cycle depends on eight enzymes that oxidize acetyl-CoA into two molecules each of carbon dioxide (CO2) and water (H2O). Thus, the citric acid cycle is a series of chemical reactions that are key to breakdown carbohydrates, fats and proteins into CO2 and H2O in order to produce energy (ATP).

As a result of the non-selectivity of the kidney's filtration of small molecules, _____. see concept 44.4 (page 986)
kondor19780726 [428]
As a result of the non-selectivity of kidney's filtration of small molecules, useful substances must be selectively reabsorbed to the blood.  Filtration is the mass movement of water and solutes from plasma to the renal tubule that occurs in the renal corpuscle. About 20% of the plasma volume passing through the glomerulus at any given time is filtered. Glomerulus lets fluid and waste products pass through it, however, it prevents blood cells and large molecules, mostly proteins, from passing.

Estimate how much the brain would swell due to osmosis if the concentration of the cerebrospinal fluid fell to 280mM. In other w
AnnZ [28]

Answer:

The correct answer is 6.67 %.

Explanation:

The average osmotic pressure of the brain is 300 mM

Given the concentration of solution is 280 mM

Difference is 300 - 280 = 20 mM

This difference is sufficient to stimulate osmosis and make water move from CSF to the brain until the concentration becomes similar.  

Also, it is known that the volume of brain is about 1200 ml on an average,  

Volume of fluid moved because of osmosis = 20 mM / 300 mM * 1200 ml = 80 ml

Percent swelling of brain = 80 ml / 1200 ml * 100 = 6.67 %
