4.6 billion years ago
The study pushes back the clock on the origin of Earth's water by hundreds of millions of years, to around 4.6 billion years ago, when all the worlds of the inner solar system were still forming. Scientists had suspected that our planet formed dry, with high-energy impacts creating a molten surface on the infant Earth.
i hope this helped, have a nice day! (o:

Biosphere- The ecosystem comprimising the entire Earth & the living organisms that inhabit it. Example: Where life occurs on, Earth
Biome- A large naturally occuring community of plants and animals Example: Rainforest, Tundra, Desert, Marine, Grasslands, etc
Ecosystem- A community of living organisms called producers, conumers, decomposers. Example: Plants (Producers) Rabbits (Consumers) Worms (Decomposers)
Community- Interacting group of various species Example: A forest of trees inhabited by animals.
Population- Traits of a group of plants and animals Example: 4 rabbits have broenn fur and 2 have black fur in a group.
Individual- Individual organisms Example: An otter is a organism
Abiotic examples- Air, soil, sunlight, or water
Biotic examples- A frog, a leaf, or a tree
Answer:
<em>The genotype of the plant will be PpSs and the phenotype will be purple colour and smooth shaped. </em>
Explanation:
Considering the description in the question, we know that purple colour is dominant over the yellow colour and smooth shape is dominant over the wrinkled shape.
A homozygous trait can be described as a trait which arises due to the same alleles of a gene. A heterozygous trait arises when both the alleles of a gene are different. In such a case, one allele will be dominant over the other one and the phenotype of the dominant allele will be seen in the plant. As purple colour and smooth shape are dominant traits, hence they will be seen in the heterozygous plant.
