In a physical change, the chemical bonds inside the material affected does not change. Same matter, just changed to look different. Like snapping wood in half.

A chemical change is when the chemicals are changed to re-arrange into different forms. An example of this is burning wood into ash. It cannot turn back into wood, it is only ash.

Natalka [10]

Answer:

D. Adrenaline

Explanation:

Adrenaline hormone is secreted by adrenal medulla during stressful conditions. The hormone is involved in preparing the body for stressful conditions by intensifying the sympathetic response.

If a person is chased by a dog, the adrenaline hormone is released from the adrenal medulla. The hormone triggers the preganglionic neurons of the sympathetic division of the autonomous nerve system to generate the flight or flight response.

Adrenaline increases the heart rate, blood pressure, and blood flow to skeletal muscles and adipose tissues. The hormone also triggers the dilation of airways and increases the blood levels of glucose and fatty acids.

Brut [27]

Answer

Cells use the hydrolysis of adenosine triphosphate, abbreviated as ATP, as a source of energy. Symbolically, this reaction can be written as

$ATP(aq)+H_{2}0(l)- > ADP(aq)+H_{2} PO\frac{}{4} (aq)$

where ADP represents adenosine diphosphate. For this reaction, a. Calculate at b. If all the free energy from the metabolism of glucose

$C_{6} H_{12}O_6(s)+6O_2(g)- > 6CO_2(g)+6H_2O(l)$

goes into forming ATP from ADP, how many ATP molecules can be produced for every molecule of glucose?

$C_6H_1_2O_6(s)+O_2(g)- > 6CO_2(g)+6H_2O(l)$

goes into forming ATP from ADP, how many ATP molecules can be produced for every molecule of glucose?

Thanks!

¿Cuál es la fuente de agua inmediata para el sudor producido por las glándulas sudoríparas?

qaws [65]

Answer:

Glándula sudorípara, cualquiera de los dos tipos de glándulas secretoras de la piel que se presentan solo en mamíferos. La glándula sudorípara ecrina, controlada por el sistema nervioso simpático, regula la temperatura corporal. Cuando la temperatura interna aumenta, las glándulas ecrinas secretan agua a la superficie de la piel, donde el calor se elimina por evaporación. Si las glándulas ecrinas están activas en la mayor parte del cuerpo (como en caballos, osos y humanos), son dispositivos termorreguladores importantes. En otros animales (perros, gatos, vacas y ovejas), son activos solo en las almohadillas de las patas o a lo largo de los márgenes de los labios y pueden estar completamente ausentes en el resto del cuerpo; Tales animales a menudo dependen del jadeo para un control efectivo de la temperatura. Los mamíferos más pequeños, como los roedores, no pueden soportar la deshidratación y, por lo tanto, no poseen glándulas ecrinas.

Espero que esto sea útil! (el español no es lo que normalmente hablo, así que espero que la traducción no sea tan mala)
