Angiosperms are plants that have stems, roots and leaves. Moreover, these plants have seeds in a flower. Usually, angiosperm eggs are fertilized through pollination in a flower. Flowers have both male and female reproductive organs. Based on the analysis of the nucleotide sequences of genes, it appears that the ancestors of angiosperms were adapted for survival in shady forests.
Answer:
- The ras proto-oncogene is converted into an oncogene
- Specific transcription factors are activated by phosphorylation
- Abnormally rapid cell growth and proliferation is induced
Explanation:
The Ras genes are proto-oncogenes, i.e., genes with oncogenic potential that may induce cancer. These genes (Ras) encode GTPase proteins involved in transducing survival and growth signals. When Ras genes suffer mutations, the resulting Ras proteins may remain in an active state that prevents the hydrolysis of GTP, thereby the Ras pathway remains constitutively activated. In consequence, mutated Ras genes function as oncogenes by constitutively activating MAP kinases which in turn activate transcription factors that control the expression of target genes involved in critical cellular processes and whose expression is associated with cancer-specific events (eg., increased angiogenesis, increased cell proliferation, reduced apoptosis, etc).
A conversational plan with two habitat preserves, measuring a total of 20 square kilometers combined will preserve more species because this cause segregation of species based on their adaptability towards a safer and secure environment. For example if a lion and deer try to live in the same conservation area, then it’s obvious that the life of deer is always at risk. But in cases of segregated preserved areas both herbivorous and carnivorous animals can live separately. Also if there is special inclination of one species towards other then also these two species can live separately.
Segregation also enhances the diversity in the sense that it could lead to a new ecosystem with a new ecological balance within it. Conservation biologists focus on these areas as they claim that where the greatest number of unique species can be found and protected with in the large number of reserve areas with the least amount of effort
B. They will become separate species.
Both traits are advantageous, so neither will take the trait of the other randomly. There is no reason to think either will necessarily go extinct.
