Human muscle cells are facultative anaerobes thal perform lactic acld fermentation when oxygen is depleted from muscle tissues, During periods of high physical activity, such as a 100-meter sprint, ATP Is rapidly used for muscle contraction The limited oxygen delvered to muscle cells becomes a problem, and aerobic respiration is blocked. In Anaerobic respiration, the ATP provided by rapid fementation, temporarily provides energy to maintain musde function in the absence of oxygen until oxygen levels are restored. A. Glucose + Oxygen (O 2)
B. Ethanol + Carbon Dioxide (CO 2)
C. Water + Carbon Dioxide (CO 2)
D. Lactic Acid + Oxygen (O 2)

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.
