Mutations have a positive effect on an organism
Katen [24]
Yes and no, without mutations, there would be no biodiversity, a lack of biodiversity results in vulnerability for excitation. Mutations can also be negative and debilitating for organisms. Without mutations, there would be no differentiation in the genetic pool.

DUE TUESDAY WILL MARK BRAINLIEST-breathing is required for cellular respiration. use the reactants, products and stages of cellu
vova2212 [387]

Explanation:

Breathing, is necessary as it repleneshes oxygen in cells; it also expels CO2 and water vapor, which are waste products from cellular respiration.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate (through the process of glycolysis in the cytoplasm).

overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP

Oxidative phosphorylation describes a process in which the NADH and FADH2 made in previous steps of respiration process give up electrons in the electron transport chain these are converted it to their previous forms, NADH+ and FAD. Electrons continue to move down the chain the energy they release is used in pumping protons out of the matrix of the mitochondria.

This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow or re-enter the matrix through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP.  At the end of the electron transport, three molecules of oxygen accept electrons and protons to form molecules of water. For a breakdown of each:

  • Glycolysis: occurs in the cytoplasm 2 molecules of ATP are used to cleave glucose into 2 pyruvates,  4 ATP and 2 electron carrying NADH molecules.
  • The Kreb's cycle: in the mitochondrial matrix- 6 molecules of CO2 are produced by combining oxygen and the carbon within pyruvate,  2 ATP oxygen molecules, 8 NADH and 2 FADH2.
  • The electron transport chain, ETC: in the inner mitochondrial membrane, 34 ATP, electrons combine with H+ split from 10 NADH, 4 FADH2,  renewing the number of electron acceptors and 3 oxygen; this forms 6 H2O, 10 NAD+, 4 FAD.

The graph below compares the rates of reaction of a burning candle and an exploding firework.
marusya05 [52]

Answer:

The reaction that causes a firework to explode requires less energy to start, and occurs more rapidly than the reaction that causes a candle to burn.

Explanation:

The speed of a chemical reaction and the amount of energy required for this reaction is directly linked to the concentration of reagents present in the system. With that, we can say that the higher the concentration of reagents, the faster the chemical reaction will be due to the greater probability of collision between its molecules.

Although the reaction that causes a candle to burn has more reactants than the reaction that causes the fireworks to explode, the latter requires less energy to start. This makes the molecules of the reagents stir faster and collide more efficiently, making the reaction happen much faster.

In summary, the reaction that causes a firework to explode requires less energy to start and occurs more quickly than the reaction that causes a candle to burn.

What is the type of ultrasound that is being used in the image above?
DiKsa [7]

Answer:

I think its sharply focused ultrasound but I'm not sure

Explanation:

A fish finder utilizes high frequencies of sharply focused ultrasound, which is transmitted with high voltage in order to determine the direction fish schools are moving. Locating objects in the air is different than locating objects in the water. I hope this helped ♡.
