Scientists can learn, which types of organisms were more common during time periods, how species have evolved over time, and the relative age of different species. Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperature and pressures that do not destroy fossil remains. Dead organisms can become sediments which may, under the right conditions, become sedimentary rocks.

How does cholera coonnect with the concepts of cell to cell communication?
Advocard [28]
Cholera occurs when the G protein cannot hydrolyze GTP to GDP so the G protein is always active. This causes water and salt to leak out causing diarrhea and eventually death by dehydration.

Hope this helps!

Answer: The genotype ratio of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant is 2TT:2Tt

The phenotype ratio is that all offsprings will be tall.

The genotype ratio of a cross between two heterozygous red flowers is 1RR:2Rr:2rr. The phenotype ratio is 3 Red flowers: 1 white flower.

Explanation: From the information given, tall is dominant and short is recessive while red is dominant and white is recessive.

Let T represent the allele for tall height, t represent the allele for short height, R represent allele for red flowers and r represent allele for white flowers.

The genotype of a homozygous tall plant is TT, the genotype of a heterozygous tall plant is Tt, the genotype of a heterozygous red flowered plant is Rr.

The possible genotypes of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant are TT and Tt.

Tt will manifest outwardly as tall because T is dominant over t. Therefore, all the offsprings will be tall.

The possible genotypes of a cross between two heterozygous red flowers are RR, Rr and rr. RR will manifest as red, Rr will also manifest as red because R is dominant to r while rr will manifest as white because white allele (r) is recessive. Therefore 3 plants will be red-flowered while 1 plant will be white flowered.

See the attached punnet squares for details of the cross.
