Your 82-year-old grandmother was diagnosed with alzheimer's disease 4 years ago. your mother is very concerned about the potential of being diagnosed with alzheimer's disease herself. she has been an avid runner for many years and vigorously exercises at least five times a week for 20 to 30 minutes a day. what would you tell your mother

Basically  exercise maintains the integrity of white matter which contains billions of neurons;

Therefore regular exercises reduces Alzheimer's diseases by 50 %. it  stimulates the  brain's ability  to maintain old neuronal connections (synapses), and  to make new ones.

Generally, exercise, increases cerebral blood flow, and therefore Oxygen supply to the brain.This stimulates neuronal metabolism.

Explanation:

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 !
