Artist 52 [7]
No that is just, no just no. DNA is copied through cell reproduction where a cell splits to create more (growing for multi called organisms and asexual reproduction for single celled organisms) The mitochondria is an organelle that is the "power house" of the cell, the "digestive system".

<h2>Homologous</h2>

Explanation:

  • <em>Two or more species share a unique physical feature,</em> for example, an unpredictable bone structure or a body plan, they may all have acquired this component from a typical predecessor.
  • Physical highlights shared because of developmental history (a typical progenitor) are said to be homologous.  
  • <em>The front flippers of whales and the forelegs of four-legged vertebrates like canines and crocodiles are completely gotten from the equivalent tribal tetrapod structure.</em>

Compare and contrast three metabolic pathways by choosing whether the statement applies to aerobic respiration. Check all that a
Arte-miy333 [17]

Answer:

The correct answer will be options

1. Process includes glycolysis.

2. Between 2 and 38 ATP are produced per molecule of glucose input .

3. Much or most of the ATP produced is produced by oxidative phosphorylation.

4. Process involves electron transport and chemiosmosis.

5.  End products are CO₂ and H₂O.

6. Process involves the Krebs cycle.

Explanation:

Cellular respiration is the oxidative process which involves the breakdown of food molecules like glucose, amino acids and fats to release heat and energy in the form of ATP.

In the presence of oxygen or aerobic respiration it undergoes four stages: glycolysis, link reaction, Krebs cycle and electron transport chain while in the anaerobic reaction it produces ethanol and carbon dioxide by the process of fermentation.

Each stage produces energy in the form of ATP molecules or co-enzymes NADH OR FADH₂ like glycolysis produces 2 ATP and link reaction, Krebs cycle produces NADH OR FADH₂ in addition to ATP. Each NADH produces 3 ATP while Each FADH₂ produces 2 ATP during electron transport chain.  So, ATP molecules are produced between 2 to 38 ATP molecules in each stage with large number during electron transport chain from these co-enzymes.

The waste products produced in the stages of cellular respiration are CO₂ molecules and H₂O which is also known as metabolic water.

What is the quotient?<br><br><br> StartFraction 5 Superscript negative 6 Over 5 cubed EndFraction
Sedaia [141]

Answer:

1/(5⁹) or 5⁻⁹

Explanation:

This is a Mathematics question rather than a Biology question.

The given fraction is:

\frac{5^{-6}}{5^3}

This fraction can be rewritten as:

\frac{1}{5^6*5^3}=\frac{1}{5^9}=5^{-9}

Therefore, the quotient of the given fraction is 1/(5⁹) or 5⁻⁹
