While conducting an investigation, you observe that exposing inner mitochondrial membranes to ultrasonic vibrations disrupts the

membranes. The membrane fragments reseal "inside out," forming small vesicles. These vesicles are still able to transfer electrons from NADH to oxygen and synthesize ATP. Based on these observations, what must be present in the membrane?

Answer:

The four protein complexes of electron transport chain and ATP synthase

Explanation:

The electron transport chain present in the inner mitochondrial membrane has four protein complexes, known as complex I to complex IV, embedded in it.

Electrons from NADH are carried to the terminal electron acceptor, the molecular oxygen, via these protein complexes.

The electron transport through the protein complexes is coupled with the formation of proton motive force which in turn drives ATP synthesis with the help of ATP synthase enzyme.

Question 4 (1 point)<br> Why are nonsense mutations rare?
Lostsunrise [7]

When a DNA sequence alteration results in a stop codon rather than a codon that specifies an amino acid, it is known as a nonsense mutation. This is rarely seen in 10% of patients with genetic disease.

<h3>What is nonsense mutation?</h3>

A nonsense mutation in a DNA sequence causes a premature stop codon, also known as a nonsense codon, in the transcribed mRNA as well as a shortened, ineffective, and typically nonfunctional protein product.

Because stop codons, also known as nonsense codons, signal the completion of protein synthesis rather than encoding for an amino acid, they are the source of the term "nonsense mutation."

Examples of illnesses for which nonsense mutations have been implicated as contributing factors include: Cystic fibrosis (produced by the G542X mutation in the cystic fibrosis transmembrane conductance regulator); (CFTR) Beta-globin (thalassemia) Hurler disease.

Describe the<br> relationship<br> between the age<br> of rock layers and<br> an unconformity
marshall27 [118]

Answer:

Laws of stratigraphy help scientists determine the relative ages of rocks. This law states that deeper rock layers are older than layers closer to the surface. An unconformity is a gap in rock layers. They occur where older rock layers eroded completely before new rock layers were deposited.

Explanation:

The study of rock strata is called stratigraphy. The laws of stratigraphy can help scientists understand Earth’s past. The laws of stratigraphy are usually credited to a geologist from Denmark named Nicolas Steno. He lived in the 1600s.

Hope this helps!
