Lymphatic system- is it open or closed? explain what it means

Biology
1 answer:
Aleonysh [2.5K]3 years ago
8 0
Lymph is the excess blood plasma after it is filtered from interstitial fluid, when the interstitial fluid is formed.  From the circulation system, after filtration, lymph is comes into to the Lymphatic system.
The Lymphatic system with its tubular vessels, is an open system. It conducts lymph between various parts of the body.  It provides a route for the excess interstitial fluid to be returned back to blood.

On the other hand, Our cardiovascular system - responsible for circulation of blood - is a closed system. Blood never leaves the veins, arteries, and capillaries.

The process of natural selection
Stella [2.4K]

Answer:

3. shapes the genetic characteristics of a species as a consequence of adaptation

Explanation:

Natural selection is a process characterized by how plants and animals that are able to adapt to changes in their environment are able to survive and reproduce while those that are unable to adapt do not survive.

In natural selection, those variations in the genotype which increases an organism’s chances of survival and procreation are preserved and multiplied from generation to generation at the expense of less advantageous variations.

Natural selection is a way of enhancing the preservation of a group of organisms that are best adjusted to the physical and biological conditions of their environment and may also result in their improvement in some cases.

A cell that consists of a 65% salt concentration is placed in a solution with a 27% salt concentration. What will happen to this
zzz [600]

Answer:

The correct answer would be - the cell will get water and expand.

Explanation:

If a cell with a higher salt concentration is placed ins a low salt concentration solution then the water will move through the cell membrane into the cell and the cell will swell or expand.

Water always moves from a low solute concentration to a high concentration area, therefore, if the cell has more salt concentration than outside the cell water move inside the cell which leads to an increase in the water concentration inside the cell and expands its size.

Which statement regarding the energetics of the citric acid cycle is true?(A) All of the energy‑producing capacity of the cycle
Step2247 [10]

Answer:

The correct answer is C production of FAD to FADH2 by the citric acid cycle represent the energetic capacity to synthesize about 1.5 ATP.

Explanation:

Citric acid cycle is one of most important stage of cellular respiration.Citric acid cycle or TCA  cycle composed of various enzyme catalyzed biochemical reaction.

 various reduced coenzymes are produced during TCA cycle such as NADH,FADH2.FADH2 is formed from FAD during the conversion of succinate to fumarate.

  The FADH2 then enter electron transport chain to oxidize itself into FAD along with the generation of 1.5 ATP.
