Answer:

The mitochondrial DNA (mtDNA) is passed down from the mother to the children almost unchanged. The analysis of mtDNA has provided the forensic scientist with essential tools for determining the source of DNA that they have recovered even from small biological samples. Thus, the answer to the question above is letter B.

What does cellular respiration have to do with metabolic processes?
bixtya [17]

Answer:

Metabolism refers to all the chemical reactions in the body, including those that use oxygen and create carbon dioxide. Oxygen and carbon dioxide, therefore, are involved in both respiration and metabolism. Metabolic reactions are sometimes referred to as cellular respiration, which can cause confusion.

Help please!........................................................
bogdanovich [222]

Answer:

The correct order would be

  • Glucose
  • ATP→ADP
  • H₂O
  • Pyruvate
  • CO₂

Explanation:

Following reactions occur in Glycolysis and Kreb's Cycle

  1. Phosphorylation of Glucose- In the first step of glycolysis, Glucose is converted into Glucose-6-Phosphate using 1 ATP molecule by Hexokinase enzyme. One phosphate group from ATP is attached to glucose by the enzyme, thus forming ADP.
  2. Dehydration- In the ninth step of Glycolysis, each of two molecules of  2-Phosphoglycerate are converted to Phosphoenol Pyruvate, by Enolase enzyme, releasing two H₂O molecules.
  3. Formation of Pyruvate- In the last or tenth step of Glycolysis, each of two molecules of Phosphoenol Pyruvate are converted to Pyrutave using an ATP by the enzyme Pyruvate Kinase.
  4. Oxidation Of Pyruvate to Acetyl-CoA- Before the Kreb's Cycle starts, the Pyruvate molecule obtained from the Glycolysis undergoes oxidative decarboxylation producing Acetyl-CoA and release of CO₂ and NADH.

The _________________ is composed of and endothelial layer that is continuous with the endocardium of the heart.
hram777 [196]

The t<u>unica media</u> is composed of an endothelial layer that is continuous with the endocardium of the heart.

<h3>What is tunica media?</h3>

Collagen, elastin, and smooth muscle cells make up tunica media. It is located halfway between the tunica externa and the tunica intima. The transverse arrangement of its strands and color make the middle coat (tunica medium) distinct from the inner (tunica intima). It not only supports the vessel but also alters the vessel's width to control blood pressure and flow.

Elastic fibers make up the majority of the tunica media in bigger vessels. The number of elastic fibers reduces as arteries get smaller, whereas the number of smooth muscle fibers grows. The strongest of the three layers is the tunica adventitia, which is the top layer. Elastic and collagenous fibers make up its structure.

This is an animation of gel electrophoresis. which of these dna molecules is the shortest?
STALIN [3.7K]
In electrophoresis, the molecules travel between the positive electrode and the negative electrode carried by the current that is generated between them.
As seen in the image below, short fragments, due to their smaller size can travel faster than the longer fragments, so the fragments that have traveled the furthermost are the shortest. (marked E in the image)
