Answer:

Cellular Respiration (Aerobic)

Explanation:

In the mitochondria, glucose(food) is broken down into into pyruvate and the electrons are harvested and then sent to the electron chain during glycolysis in the cytoplasm. Pyruvate in converted to Acetyl CoA and enters the Krebs Cycle in the mitochrondria, and produces NADH and ATP. NADH goes to the electron chain and releases electrons and turns into NAD+.  The electron transport system is embedded in the membrane, and this system creates a Hydrogen ion gradient. ATP synthase creates ATP through oxidative phosphorylation, and is powered by the diffusion of the hydrogen ions. THe hydrogen ions combine with the electrons and an oxygen atom to form water. Without oxygen as the final acceptor, the mitochondria cannot produce ATP energy using the ATP synthase and is forced into anaerobic respiration. With oxygen, the mitochondria can perform normal aerobic respiration.

Answer:

The answer is Vitamin E or α-tocopherol.

Vitamin E is a <u>fat-soluble</u> vitamin is first absorbed in the small intestine and is then <u>stored at the liver</u>. It is an <u>antioxidant</u> which <u>protects cells from free radicals or reactive oxygen species (ROS)</u>. It can also prevent bad cholesterol from depositing in the blood vessels.

Vitamin E can be <u>naturally found in nuts, seeds, and vegetable oils</u>. As a dietary supplement, it takes the form of  α-tocopherol. The RDA depends on the age of the person, as it may range from <u>4 mg to 15 mg per day</u>.

<u>Vitamin E deficiency is so rare</u> that it will only occur if the person has a <u>fat malabsorption illness like Crohn's disease, abetalipoproteinemia</u>, etc. Symptoms of deficiency include <em>muscle weakness, retinal degradation, peripheral neuropathy, and an immunocompromised state</em>.

Evolution and Natural Selection

Based on the information in the chart, what can we conclude about the functionality of various sized beaks.
denis23 [38]

The correct answer is - B. Beak size determines what the bird can eat.

The beak of a bird can come in many different shapes and sizes. It can be pointy, long, short, rounded, scythe-like, thin, thick... All of those shapes and sizes have a specific role, and that role is to enable the bird to feed itself with certain type of food source. Every food source requires certain type of beak in order for the bird to be efficient in getting its nutrition, so depending on hat the bird eats, we can easily see a pattern in the beaks, where birds that eat nuts have one strong and shorter beak, the ones that eat warms and insects have thin, pointy one, the predator birds have claw like, sharp beak...
