analyze this punnett square:

1. in this punnett square, what is the ratio of homozygous to heterozygous offspring? (hint: homozygous means ''the same''; heterozygous means ''different''.)
homozygous: heterozygous

2. in the punnett square, what percentage of the offspring are homozygous recessive?

answers can be in this format:

1. : is the ratio of homozygous to heterozygous offspring.
2. % are the homozygous recessive.

1. ___1___ : 1 is the ratio of homozygous to heterozygous offspring.

The answer is 1:1. It could also be expressed in percentage which is 50% : 50%. This is derived by dividing the number of a particular genotype against the whole offspring population. In this case, each genotype is 2/4 * 100 in percentage.

2. ___50 % are the homozygous recessive.

The answer is 50%. Homozygous recessive means that, in the genotype of the offspring, both alleles of the gene are recessive. In this case, it is rr. As indicated above, this is derived by 2/4 * 100 since there 2 out of 4 of the offspring are recessive homozygous.

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen

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 !
