Why are capillaries thin walled?

Answers

Answer 1
Answer: Capillaries are thin walled so that the nutrients ,lipids and water can easily diffuse out from blood into the tissues,,,
And the waste products and carbon dioxide can diffuse back into the blood and carried away for the removal from body...
Answer 2
Answer: The smallest capillaries or capillary blood vessels in the body is the name given. Mu.m to about sizes 5-10. Combining with arterial venous capillaries, tissue interaction are the most densely blood vessels. From a single cell layer of capillary walls (endothelium) occurs. This layer is so thin that oxygen, water and molecules such as lipids enter tissues by diffusion from the substrate can pass. Pests such as carbon dioxide and urea, and waste materials in the blood capillaries are distributed by diffusion. With the release of certain cytokines capillaries permeability (permeability) can be increased further. 
The average total length of capillaries in the human body is about 40,000 km. Connecting arteries with veins, thin veins are composed of a single row of epithelial tissue. Exchange of substances between blood and tissue cells and the blood flow is slow provide.

In the human body, carbon monoxide reduces the amount of oxygen that can be transported to cells. Breathing in too much carbon monoxide will most likelyresult in the production of1. less ATP
2 less glucose
3 more DNA
4 more protein

Answers

Breathing in too much carbon monoxide will most likely result in the production of less ATP.

How  breathing carbon monoxide can affect production of ATP?

Carbon monoxide reduces the amount of oxygen that can be transported to cells.

Cell generates ATP from the process of cellular respiration in the mitochondria.

Aerobic respiration use glucose and oxygen to form ATP.

If the amount of oxygen is reduced, then it will directly affect the cellular respiration and hence, the production of ATP.

Biology shows us the fossil record and comparative anatomies. Chemistry shows us that organic molecules can come from inorganic matter. Geology shows us that organisms that used to live together are found on separate continents due to continental drift. Which fields of science provide evidence for evolution? a.)biology only b.)biology and chemistry c.)biology and geology d.)biology, chemistry, and geology HEELLLLLP PPPLLLSSS

Answers

The answer to your question is D. To create the full picture of evolution, and how the species that exist on our planet came to exist in their current forms, it is important to take in information from all the possible fields of science including biology, chemistry and geology.

Biology, chemistry, and geology is the answer.

Which of the following must unicellular organisms do to maintain homeostasis? A. Specialize cells to perform specific functions
B. Organize cells into tissues
C. Use chemical signals to communicate between its cells
D. Change food or sunlight into useful energy

Answers

The answer is C. Homeostasis is the process within a cell which aims at maintaining equilibrium within the cell. All living cells exhibit this process. Homeostasis happens by detecting and responding to slight changes in the normal processes inside the cell. Homeostasis occurs by regulating the movement of substances in and out of the cell to maintain a stable concentration inside the cell. It uses chemical signals to communicate between its cells.

The voyge of the beagle circled the globe. This voyage lasted? A.5months B.2 years C.4years D.5years

Answers

The voyage of the HMS Beagle is led by the scientitstCharles Darwin in search for species around the globe and  a curious observation that led him totheorize about evolution. It leaves form Plymouth Harbor, toured around theMadeira and Canary islands and made a landfall at the Cape of Verde islands. Theexpedition was originally planned to end in two years. It got delayed andturned into five years due to Darwin spending most of his time exploring onland. the answer is D.
