While cleaning out the garage, Duane found his old bicycle. Some of the paint had worn off, exposing the iron frame inside. Duan

e noticed that parts of the iron frame had become reddish-brown and rough and that parts were flaking off. What happened to Duane's old bicycle? A Oxygen from the humid air chemically reacted with the iron in the frame, creating rust, a new substance with different properties. B Oxygen from the humid air physically reacted with the top layer of iron, wearing it away to expose the natural rust underneath. C The circulating air in the garage deposited a layer of rust on the iron frame. D The iron in the frame naturally decomposed into rust without any reaction.

Answer: option A - Oxygen from the humid air chemically reacted with the iron in the frame, creating rust, a new substance with different properties.

Explanation:

Rusting refers to the deteriorated state of IRON as a result of moisture (water molecules) and oxidation (addition of oxygen)

For example: The rust on a bicycle chain can make cycling to work very difficult.

Also, note that RUST has a reddish-brown color. So, RUSTING has affected Diane's bicycle

Match the creature to its distribution pattern.
lorasvet [3.4K]

Answer:

The correct match would be:

  • Swallow - migration
  • Tiger - sparse distribution—scarce
  • Devil’s Hole pupfish - local endemic
  • Humpback whale - sparse distribution—widely dispersed

Swallows are small migratory birds belonging to the family Hirundinidae found all around the world. Migrating swallows can cover around 200 miles in a day.

Tiger has become endangered species due to excessive hunting and habitat loss. It is estimated that only 3800 tigers are left in the wild.

Devil’s Hole pupfish is a species of a fish only found in Devils Hole which is a  geothermal aquifer-fed pool located in Ash Meadows National Wildlife Refuge  in Nevada city of the United States

The humpback whale or <em>Megaptera novaeangliae</em> is a species of baleen whale which is widely distributed in all major oceans including Pacific, Atlantic, and Indian oceans.

Which statement BEST describes the relationship between adenosine diphosphate (ADP) and adenosine triphosphate (ATP)? A. With an
Shalnov [3]

Answer:

The correct answer would be  C. With an input of energy, ADP combines with a phosphate group to become ATP.

Inorganic phosphorus and energy are added to adenosine diphosphate (ADP) in order to convert it to adenosine triphosphate (ATP).

This reaction is usually catalyze by the enzyme ATP synthase. It present in inner membrane of mitochondria of the cell as well as in the thyllakoid membrane in chloroplast.

ATP synthase uses the energy provided by chemiosmosis i.e. flow of protons down the gradient across the membrane through this enzyme. Proton gradient is formed either by photosynthesis or by cellular respiration.

ADP + inorganic phosphate (Pi) + energy → ATP + H₂O

ATP is used as the energy currency of the cell which breaks down to release inorganic phosphate group and energy which is used in various metabolic processes.

Marcia is diagnosed with hypermetabolism.  One pathological cause of hypermetabolism is thyroid disorder (hyperthyroidism). It could also be caused by injury or infection in the body. There is no single treatment for the disorder since it is merely a symptom of an underlying problem. It could be managed by nutritional support coupled with pharmacological treatment such as diuretics and regular insulin.
