A) Water cannot be absorbed through the surface of a leaf.
Answer:
THE BLOOD CELLS FLOWING THROUGH THEM WOULD NOT BE ABLE TO EXCHANGE GAS WITH THE SURROUNDING TISSUE
THE BLOOD CELLS WOULD FLOW SLOWLY THROUGH THEM, PREVENTING THEM FROM CARRYING OXYGEN TO TISSUE
THE BLOOD CELLS FLOWING THROUGH THEM WOULD FORM CLOTS ALONG THEIR WALLS THAT BLOCK FLOW TO TISSUE.
Explanation:
Capillaries are connecting vessels that connects the arteries and veins. They are only two-celled thick vessels and allows the exchange of ions, solutes and other essential nutrients except plasma proteins which are large proteins and cannot undergo simple diffusion into cells. The type of circulation in capillaries is called micro-circulation.Capillaries pick up oxygen in the blood to the tissues and carbon dioxide to be eliminated from the tissues. So if the capillary walls are thicker than normal, it functions disappears. It probably becomes an artery or a vein. Gaseous exchange with the surrounding tissue is affected, nutrients carriage is impaired and blood cells can not flow through them in a single file as the case in normal capillaries with two cell layer thickness. Blood cells will therefore flow slowly through them and this affect the delivering of oxygen to tissues. Also, because of the inability of the blood cells to flow properly, blood clots could bee formed along the walls of the capillaries and hinder blood flow to the tissue.
It is the macroscopic anatomy with a systemic approach.
There are two levels of the human body: macroscopic (gross anatomy) and microscopic level. For each of the two levels, there is a separate subdivision of anatomy.
There are two approaches for gross anatomy:
1. Regional approach-human body is divided into regions like arm, forearm, wrist etc. Structures within that region are studied simultaneously.
<span>2. Systemic approach-the body is divided into organ systems like skeletal system, or nervous system and structures belonging to one system are studied together.</span>
Answer:
La glucosa proviene de la conversión fotosintética de la energía electromagnética (luz) en energía química. La energía química es una forma de energía potencial microscópica, es decir, es la energía almacenada en enlaces químicos entre átomos dentro de las moléculas de cualquier compuesto altamente energético. Los compuestos orgánicos tienden a tener una energía (química) de alto potencial, cuando los quemas obtienes esa energía. Quemar significa hacer que reaccionen con oxígeno y se conviertan en compuestos menos reactivos (menos energía). Si quemas un palo de madera en un fuego óseo o si respiras glucosa en tus células, estás permitiendo que el oxígeno oxida esos compuestos altamente energéticos, al final del proceso, los enlaces químicos de la glucosa (o la madera) se rompen y qué los restos (productos químicos) son agua y dióxido de carbono (compuestos de baja energía). La diferencia de energía entre glucosa + O2 (reactivos con alta energía química) y H2O + CO2 (productos con baja energía química) es lo que surge de la reacción, que es luz y calor en un incendio óseo o ATP en la respiración celular. Esta energía resultante es utilizada por los humanos para obtener calor o luz y por las células con fines metabólicos, de hecho, las células viven de la energía producida por la respiración celular.
