Answer:

- In glycolysis, glucose is split into two pyruvate and makes some ATP

- The Krebs cycle produces ATP, NADH and CO2

- NADH gives electrons to the ETC

- As electrons move down the ETC, a H+ gradient is made

- H+ pass through the ATP synthase to make ATP

Explanation:

This question is describing the processes involved in cellular respiration. Cellular respiration is the way through which living cells synthesize energy (ATP) by breaking down sugar. Cellular respiration involves three major steps: glycolysis, Krebs cycle, and oxidative phosphorylation (electron transport chain).

- Glycolysis is the process whereby glucose is broken down into pyruvic acid or pyruvate with the synthesis of net 2 ATP molecules.

- Kreb's cycle produces ATP, NADH and CO2.

- NADH is an electron carrier that donates electrons to the Electron transport chain (ETC).

- Electrons move down the ETC to produce a proton (H+) gradient

- The proton (H+) passes through an enzyme called ATP synthase to make ATP from ADP molecule.

A sample of DNA reveals 30.3% Adenine. How much Guanine is present?
tiny-mole [99]

Answer:

69.7%

Explanation:

Adenine base pairs with thymine

guanine base pairs with cytosine

you need to get to 100%

30.3-100=69.7%

There will be 30.3% or adenine and thymine and 69.7% or guanine and cytosine.

Regan is trying to determine if an unknown element is a metal. She does not want to damage or change the physical appearance of
34kurt

Explanation:

Well, one could use a magnet to see if it's ferrous. One could melt it to check which type it is, use a metal detector, or just use their senses: If it dings or clinks like metal, and feels like it’s texture. If it polishes with metal polish, is reflective, can be shaped or shape when heated… It usually is a metal. If it rusts, or oxidizes, it is or contains metal. If it “smells" like metal, most likely, it is metal. Finally, if it walks like metal, and quacks like metal, most likely we have a metal

in what way are heterotrophs dependent on photosynthesis by autotrophs (explain at a 6th grade level)
aleksley [76]
Hello! Autotrophs make their own food (plants) and heterotrophs consume other organisms for energy (consumers.) Autotrophs use the process of photosynthesis to produce the oxygen as one of its products. Heterotrophs use the oxygen produced by the autotrophs to perform cellular respiration, which releases carbon dioxide that plants use; it's a balanced cycle. Hope this helps!

sladkih [1.3K]

Hello. This question is incomplete. The full question is:

"Scientists are testing the effect of different scrubber technologies on the removal of pollutants from coal power plants. The scrubbers use a slurry of limestone and water. Which of the following best describes the impact of modifying the slurry by increasing the amount of limestone? The amount of sulfur dioxide released will decrease. A The amount of ground-level ozone released will decrease. B The amount of water released will increase. C The amount of carbon monoxide released will increase. "

Answer:

The amount of sulfur dioxide released will decrease.

Explanation:

As you may already know, coal is a fossil fuel and burning it releases many toxic gases into the atmosphere, including sulfur dioxide.

A suspension of water and limestone, allows the calcium present in limestone to enter into reaction with sulfur dioxide, forming calcium sulfide and decreasing the emission of sulfur in the atmosphere.

The greater the amount of limestone in this suspension, the less sulfur dioxide will be released into the environment.
