Which is a dominant trait that mendel observed in pea plants?
bumpy pods
short height
yellow seeds
white flowers

Ans.

A dominant trait can be defined as a trait that can be physically expressed in heterozygous as well as in homozygous state. The allele for dominant trait can mask the phenotype of another allele or recessive allele.  

In pea plants, studied by Mendel, presence of yellow seeds was a dominant trait over green seeds that represented a recessive trait. In these plants, presence of one allele for yellow seed could hide the expression of allele for green seed.

Thus, the correct answer is option) 'yellow seeds.'

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.
