Answer:

a. Acetyl-CoA

Explanation:

Pyruvate is decarboxylated in the matrix of mitochondria and loses its carbon as CO2. This decarboxylation is accompanied by its oxidation as well. This process of oxidative decarboxylation of pyruvate is catalyzed by an enzyme complex. It is called the pyruvate dehydrogenase enzyme complex. NAD+ accepts the released electrons and pyruvate is converted into energy-rich acetyl CoA which in turn enters into the Kreb's cycle.

<h2>Answer:</h2>

<u>Igneous basalt rock </u>

<h2>Explanation:</h2>

The peripheral layer of Earth's lithosphere which is found under the seas and is shaped at spreading focuses on maritime edges, which happen at different plate limit, is called as oceanic crusts.  

It is around 6 km (4 miles) thick. It is made out of a few layers, excluding the overlying residue. The highest layer, around 500 meters (1,650 feet) thick, incorporates magmas made of basalt rocks. The oceanic crust is differentiated from the continental crust through certain distinguishing features such as it is more slender, denser, more younger, and of various concoction piece.

12)Sabems que las etapas del ciclo hidrológico  son las siguientes:

Evaporación

Condensación

Precipitación.

Las implicaciones que tienen para la vida cada una de las etapas son:

Evaporación, se reduce el nivel de los ríos, los lagos pequeños se seca, y se eleva la temperatura del ambiente.

Condensación, Es el proceso en el cual se forman las nubes, por lo que la luz solar disminuye.

Precipitación, produce nuevamente el aumento de los niveles de rios y lagos, y la disminución de la temperatura.

GREYUIT [131]

Atherosclerosis

Explanation:

Correct order of the sequence of events that leads to atherosclerosis is:

c, d, b, a

Development of atherosclerosis is caused by a high concentration of LDL‐cholesterol in the blood, and lowering the level of LDL‐cholesterol reverses atherosclerosis thus preventing cardiovascular disease

Cholesterol is the key component of arterial plaques which gave rise to the cholesterol hypothesis for the pathogenesis of atherosclerosis

Population studies have shown that elevated levels of both LDL cholesterol and apolipoprotein B (apoB) 100, which is the main structural protein of LDL, are directly associated with risk for atherosclerotic cardiovascular events
