Health authorities are investigating a fictitious disease, Fever B. The first case was observed in a 30-year old male. Marcus, who is an ecological scientist with routine occupational exposure to various areas in and around the Amazon River basin. Two months after returning from a 10-day trip to Bolivia, Marcus developed a high fever, a painful vesicular rash over about 30 percent of his body, and debilitating muscle aches and fatigue. He wasn't really himself until about 6 weeks after his early symptoms developed. He reported starting to feel weak and exhausted with mild aches about 2 days before the high fever and rash developed

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 !

answer: c.

explanation:

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther

explanation:

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
