Which of the following statements about physiological age and chronological age is true? a. physiological age and chronological age are always the same. b. physiological age can be lower than, the same as, or higher than chronological age. c. physiological age can be lower than chronological age, but never higher. d. physiological age cannot be altered, but chronological age can change based on lifestyle choices.

B. Physiological age can be lower than, the same as, or higher than chronological age.

Explanation:

Chronological age represents the total number of years from birth to an individual to its death. Physiological age represents the age of with respect to the functioning of the body. It deals with the ability of body parts to carry out various functions efficiently and can be altered by following a healthy diet, daily exercise routine, and a balanced lifestyle. Accordingly, the physiological age can deviate from the chronological age of the person.

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.
