I think the answers are
Sporophyte generation: Both
Pollination: Both
Sporophyte contains male and female reproductive structures: Seed plants
Single fertilization: Both
Sperm cells transported by water to egg cells: Both
<u>Answer:</u>
Common ancestor is the main factor that determines that all terrestrial animals are quadrupedal.
<u>Explanation:</u>
- Phylogeny means the evolution of the organisms or genetically related organism and how they are related.
- The study of phylogeny is called as phylogenetics. Terrestrial means those who live on land.
- Mammals are one who gives birth to their offspring directly. They are generally warm-blooded, breath air.
- Studying each state of the ancestor and also tracing the organism characteristics during evolution.
Answer:
a. The allele for round seeds is dominant to the allele for wrinkled seeds.
Explanation:
Mendel found that when two pure breeding plants that differ from each other with respect to one genetic trait are crossed, all the progeny express the phenotype of one parent. The phenotype of the other parent is not expressed in the progeny. He concluded that the genetic trait that is expressed in the F1 generation is dominant over the other which is masked in this generation.
A cross between pure breeding plants for round seeds and the wrinkled seeds obtained all the round seeded progeny. This meant that the phenotype "round" was dominant over the phenotype "wrinkled". If the allele "R" gave round phenotype and the allele "r" imparted wrinkled phenotype, the allele "R" was dominant to the "r".
Answer:
b the turgor pressure will increase but the cell wall prevents the cell from exploding
Explanation:
The plant cells are exposed in a change of pressure liquid depending the quantity of solids that are inside and outside the cell. Like in this case, the hypotonic solution is the one that has less solids outside the cell, that is the reason why the water enters the cell to equilibrate the concentration of solids inside and outside the cell.
