How do the finger-like projections facilitate the absorption?

Biology
1 answer:
Nesterboy [21]3 years ago
4 0
Finger- like projections facilitate absorption in the following ways;
a) They increase the surface area of the organ eg. small intestines to allow more area of nutrients to be absorbed. The larger the surface area the more nutrients are absorbed.

b) They contain many capillaries which helps to increase the rate of nutrients absorption in the small intestines.

One common test of language lateralization is invasive; it involves injecting ____________ into the carotid artery.
vova2212 [387]

Answer:

barbiturate/sedatives

Explanation:

Lateralization is a process of studying the split functions of the brain hemispheres. The most common test used for testing lateralization is obtained from sodium amytal studies. In this study a barbiturate or a sedative is injected into the carotid artery either left or the right artery. So, till the time the barbiturate hampers the functioning of any hemisphere, the functions associated with that hemisphere also gets hampered or are sustained for a while. This technique is of invasive nature

Which of these is not a property of lymphatic capillaries?
Inessa05 [86]

Answer:

They are smaller than blood capillaries.

Explanation:

Lymphatic capillaries drains the extracellular fluid present between the cell spaces. The fluid is known as lymph as it enters the lymph capillaries. These capillaires drains into lymph vessels that drains to lymph nodes and lymph ultimately enters the venous circulation.

Lymphatic capillaries are slightly larger than blood vessels and these capillaries have close ends. The walls of lymph capillaries are made up  of endothelial cells. The endothelial cells overlap in lymph vessels and when the pressure in ECF is greater these cells move and create a sort of gap for the movement of ECF inside the lymph capillary but when the pressure inside the capillary is greater these cells again overlap and does not allow the lymph to move outside of capillary. Thus lymph capillaries only allow the ECF to enter the capillary but does not allow the lymph to go out from capillary. Lymph capillaries have greater internal pressure than blood vessels.

Desacribe an experiment to prove that carbon dioxide is essential for photosynthesis ?
disa [49]
Take two healthy potted plants. Keep them in a dark room for 2-3 days. Now place each plant in a separate glass. Get a cup containing potassium hydroxide by the side of the plants (the potassium hydroxide is used to absorb carbon dioxide). COver both plants with separate jars. Seal the jars so that the set-up-is-air-tight. Keep the plants in sunlight for two hours. Gently pluck a leaf from each plant. remove the chlorophyll from the leaves by boiling them in alcohol. Wash the leaves with water and then pour iodine solution over them.

We can conclude that the photosynthesis cannot be carried out without carbon dioxide. the leaf from the plant (which was the jar containing potassium hydroxide, which absorbed the carbon dioxide) turns blue black on iodine solution showing that starch is presented in this lead.

so this shows that carbon dioxide is necessary for the processs of photosynthesis to take place
