Suppose that at a given point along a capillary, the following forces exist: Capillary hydrostatic pressure (HPc) = 30 mmHg Inte
Ainat [17]

Answer:

Suppose that at a given point along a capillary, the following forces exist: Capillary hydrostatic pressure (HPc) = 30 mmHg Interstitial fluid hydrostatic pressure (HPif) = 0 mmHg Capillary colloid osmotic pressure (OPc) = 25 mmHg Interstitial fluid colloid osmotic pressure (OPif) = 2 mmHg. The net filtration pressure at this point in the capillary is <u>7mmHg.</u>

Explanation:

  • Data:

Capillary hydrostatic pressure (HPc) = 30 mmHg

Interstitial fluid hydrostatic pressure (HPif) = 0 mmHg

Capillary colloid osmotic pressure (OPc) = 25 mmHg

Interstitial fluid colloid osmotic pressure (OPif) = 2 mmHg

  • Formula Applied :

Net filtration pressure= hydrostatic pressure gradient -  Oncotic pressure gradient

Hydrostatic pressure gradient = Capillary hydrostatic pressure - Interstitial hydrostatic pressure = 30mmHg - 0 mmHg = 30 mmHg

Oncotic pressure gradient =  Capillary colloid osmotic pressure - Interstitial fluid colloid osmotic pressure =25  - 2 = 23 mmHg

Net filtration pressure= hydrostatic pressure gradient -  Oncotic pressure gradient = 30 mmHg - 23 mmHg = 7 mmHg.

Hence, The net filtration pressure at this point in the capillary is <u>7mmHg.</u>

Answer:

<u>prokaryotes</u>

Explanation:

The first living things on Earth, single-celled micro-organisms or microbes lacking a cell nucleus or cell membrane known as <u><em>prokaryotes</em></u>, seem to have first appeared on Earth almost four billion years ago, just a few hundred million years after the formation of the Earth itself.
