An enzyme known as amylase is found ins the saliva of humans. This enzyme helps to begin the process of digesting starch molecules in the foods we eat. The best description of how enzymes like amylase help in the process of digestion would be that Amylase is a catalyst that speeds up the chemical process of breaking down food molecules.
Answer:
The diagram can be improved by:
Lungs
↓
oxygen
↓
Red blood cells (carrying oxygen)
↓
Organs (like stomach and liver etc) from where carbon
is taken and oxygen is supplied
↓
RBC's carrying Carbon dioxide to the lungs
The component which is missing in the diagram are the organs where exchange of gases occurs. The red blood cells carry oxygenated blood from the lungs to all parts of the body and carries the wast carbon dioxide gas from them back to the lungs. The carbon dioxide is then exhaled by the lungs.

<span>The release of large quantities of merozoites into circulation at one time is due to a form of reproduction by Plasmodium known as exoerythrocytic schizogony.</span> <span>The intracellular parasite (inside the hepatocytes) undergoes an asexual replication known as exoerythrocytic schizogony. Exoerythrocytic schizogony culminates in the production of merozoites which are released into the bloodstream. This is the end of the asexual reproductive stage. The next target is the red blood cells<span> where the merozoites become gametocytes.</span></span>
Answer:
lípidos (fosfolípidos y colesterol)
Explanation:
Las membranas celulares están formadas principalmente por fosfolípidos, los cuales son<u> lípidos</u> compuestos por una molécula de glicerol con dos ácidos grasos unidos y un grupo fosfato. Los fosfolípidos se disponen formando una bicapa, dentro de la cual los grupos fosfatos (con mayor afinidad por el agua, es decir hidrofílicos) se orientan hacia el exterior celular y hacia el interior de la célula, mientras que las colas de ácidos grasos (hidrofóbicas, por lo que tiene mayor afinidad por sustancias no polares) se encuentran en la parte interna. Además, la membrana posee otro lípido: el colesterol, el cual tiene como principal función la regulación de la fluidez de la membrana.
