Thinking about the structure of this "pick-up organ" how is the surface area to volume ratio maximized?

Biology

4 0

If we pick small intestine as and organ we can observe its large the surface area/volume ratio. The ration between surface and volume is important, because it impact the function of the organ. In this case, small intestine absorbs the nutrients more efficiently. The surface of the small intestine is increased due to finely wrinkled internal surface and convoluted surface composed of the microvilli (cellular membrane extensions for better absorption).

List three protozoan infections of the circulatory system that are transmitted by arthropods. Include the disease name, specific
Kazeer [188]

Answer:

List three protozoan infections of the circulatory system that are transmitted by arthropods:

Malaria

Toxoplasmosis

Chagas disease (American trypanosomiasis)

Explanation:

Malaria is a prozotoan infection, that can be produced by several protozoan, in the genus Plasmodium. This Plasmodium infect red blood cells and the vector that trasmites it is the Anopheles mosquitoe. In this disease, red blood cells can have severe damage in different organs because of the hemolysis.

Toxoplasmosis is a disease caused by the protozoan Toxoplasma gondii. The main vector of them are domestic cats. When cats are infected, T. gondii oocysts is found in their feces and it can spread to humans. This disease is generally asymptomatic, except when the patient has AIDS or in pregnancy, which can be very dangerous and fatal.

Chagas disease, or American trypanosomiasis is caused by protozoan Trypanosoma cruzi and is generally transmitted to people thanks to the feces of triatomine bugs. Some of the acute symptoms include fever, vomiting, headache, and in severe cases people can develop a chronic disease. In the worst cases it can produce flaccid cardiomegaly (enlargement of the heart) leading to heart failure and death.

ANSWER CORRECTLY ASAP FOR 35 POINTS!!! ASAP AND GET BRAINLIEST!!!!!
SVETLANKA909090 [29]

Answer:

the process that would make them go as dark or light would be because they and blend in better to no the eaten it is called "latrell Selection" so in the Beach mice would stay light because they look like sand but if they were dark they would be easy to see that is why they are not there same thing for the forest but the other way around

if the forest changed to more sandy it would let lighter mice live there to but the dark mice would still live because it is not all sand i like it would be equal amount of dark and light mice because they would both have there spot to hide and just as vulnerable if the switched spots

How are the equations for photosynthesis and cellular respiration related?
Reptile [31]

Answer:

The equation of the photosynthesis becomes reverse in the cellular respiration. In both process the reactants and products are altered.

Photosynthesis is the light harvesting process. Here the plants use water, carbon dioxide, light as raw material to produce glucose, energy and oxygen. This process occurs in the chloroplast of the leaves. In this reaction the products are oxygen and glucose.

In cellular respiration, the byproduct of photosynthesis i.e. glucose is oxidised to release energy and carbon dioxide, along with the ATP molecules. This reaction is the reverse reaction of the photosynthesis.

In cellular respiration the product of the photosynthesis becomes becomes reactant.  

The cellular respiration occurs in the cytoplasm of the cell and involves many steps to release energy. The various cellular respirations are glycolysis, kreb's cycle, electron transport chains, etc.

Give a scenario where a cell may need to perform a form of endocytosis
Elanso [62]
Endocytosis is the process where a cell imports large things into the cell. All forms of endocytosis are active, meaning the cell expends ATP while performing this process. Specifically, a style of endocytosis called phagocytosis involves a cell surrounding the target material with its cell membrane and encloses it while bringing it into the cell.  This enclosed membrane bound material then pinches off into a spherical 'vesicle'.  An example of this can be a cell importing a protein into its cellular space.
