Bio_006_NGSQ2_FY21 Question: 1-7 Whales, humans, lizards, and birds each have forelimbs that are adapted for different functions, including swimming, using tools, walking, and flying
While different in function, these forelimbs share a similar skeletal structure of the humerus, radius, and ulna. How does a comparison of the forelimbs
of these organisms provide evidence for evolution?
O These homologous structures indicate that these four organisms all share a common ancestor.
O These analogous structures indicate that whales are descended from organisms that lived on land,
O These analogous structures indicate that these four organisms all experienced convergent evolution.
These homologous structures indicate that humans, whales, and birds all evolved from a lineage of lizards.

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.

meteorologists would compare a new weather map with one 24 h old to see how fast a front is moving.

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 !
