An organism must has a large surface area to volume ratio in order to exchange material easier
in animals erythrocytes have a flat concave shape that allows them to carry more haemoglobin and also increases its surface area to volume ration so that the length and availability of a surface is less for the materials to travel
multi cellular organisms tend to have flat and elongated respiratory surfaces to allow for a higher surface area to volume ratio in order to increase the rate of gas exchange
the ilium in most mammals is flat and elongated and is covered with microvilli to increase surface area and to reduce the cells volume therefore reducing its surface area to volume ratio
hope that helps
Answer:
The answer is B) arachnoid granulations
Explanation:
Arachnoid Mater and CSF Circulation:
- The arachnoid is the middle layer of the meninges which are the membranes covering the brain.
- The arachnoid is characterized by the spider web like projections that extend between it and the pia mater (outer membrane of the meninges).
- These projections are located in the subarachnoid space (space below the arachnoid). These projections contain the circulating cerebrospinal fluid or CSF.
- The arachnoid extends into the dural sinuses through the arachnoid granulations in which the CSF is filtered and added to the blood for drainage from the brain.
Answer:
they created a genetic drift that caused them to create genocid
I guess a leaf is like a factory in that it has processes that work within the leaf and that substances are produced from the leaf. The chlorophyll, or basically the part of the plant cell that gives the leaf that green color, interacts with sunlight to drive a chemical reaction that allows the leaf to take in carbon dioxide and water. With this, the 'factory' is able to produce oxygen and sugar. In plants that produce fruits and vegetables, the leaf is what does the working, providing the sugar and nutrients for that plant which makes those fruits and veggies. hope this helps!!
