Many farmers and gardeners compost their plant and animal waste. the living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. the next season, farmers use this substance as a natural fertilizer for their crops. a biology student has grown tomato plants for several years. until now, he used an artificial fertilizer formulated for tomato plants. this fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. the student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer. answer the following questions to plan an investigation using the steps of the scientific method and the student find the answer to his question. part a what are the student’s observations and inferences before he starts his investigation?

The student's observations before he starts his experiment are that his tomato plants grew faster and taller with his artificial fertilizer rather than without any fertilizer at all.

The student has observed That artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he infers that compost will make his plants grow faster then they grow in plain soil. that artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he in first that compost will make his plants grow faster than they grow in plain soil

Explanation:

Just did the test

your the dumbest b**tch ive ever seen

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 !
