Answer:
Actually, The reaction is chemical and endothermic. Chemicals A and B form an endothermic reaction, and chemicals C and D form an exothermic reaction. Therefore, chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
Explanation:
Answer:
Contaminación por quema de combustibles fósiles en vehículos, deforestación y uso de químicos en agricultura.
Explicación:
La contaminación por quema de combustibles fósiles en vehículos, la deforestación y el uso de químicos en la agricultura son los factores que generan problemas ambientales en nuestra comunidad. La quema de combustibles fósiles en vehículos e industrias libera gas de dióxido de carbono que aumenta la temperatura del área, la tala de árboles para uso doméstico tiene un efecto negativo en el medio ambiente. En nuestra comunidad, los productos químicos se utilizan para obtener una mayor producción que también contaminan los cuerpos de agua y los animales acuáticos afectados.
The condition which is most likely to cause death of a botulism patient is Respiratory failure.
Explanation:
The causal organism of Botulism is the bacteria <em>Clostridium botulinum.</em>
It is usually found in canned food and causes a very severe food poisoning.
The bacteria release botulinum toxin on reaching the intestine of the person and from their the toxins are absorbed into the blood.
Botulism mainly effects the neuromuscular system of the body. .
The basic symptoms of botulism is characterised by weaknes in limbs , jaws and eyes.
A decreased muscular activity sometimes causes constipation due to slowed down peristalsis.
Sometimes nausea , vomiting and diarrhea may occur.
If left untreated and in severe cases, the toxins may proceed to effect the respiratory muscle thus hindering the proper breathing and gaseous exchange.
A further damage could result in the respiratory failure.
The correct answer is: Protons are pumped out of the mitochondrial matrix into the intermembrane space
Chemiosmosis can be described as movement of ions across a selectively permeable membrane, down their electrochemical gradient. It occurs during the cellular respiration within mitochondria and it is involved in ATP synthesis (oxidative phosphorylation via ATP synthase).
Electrons from electron carriers (NADH and FADH) donate electrons to the electron transport chain and that causes changes in protein complexes of electron transport chain. As a consequence, protein complexes pump H+ across a selectively permeable cell membrane from the mitochondrial matrix into the intermembrane space of mitochondria.
H+ can only get back and pass through the inner mitochondrial membrane with the help of ATP synthase (down their electrochemical gradient). ATP synthase turned by the force of the H+ diffusing through it forms ATP by adding a phosphate to ADP.
