Answer:
Divergent plate boundaries because the separating of the tectonic plates allows for the lava to push its way through the rift and escape to Earth's surface.
Answer:
A. Chemical modification may allow for extended drug capacities such as expanded spectrum of activity and increased stability.
Explanation:
Any modification in antibiotic structure and chemical will affects its ability in a way to increase it capability of target microbes and act efficiently. These modification can increase half life and stability of the drug.
Answer:
Permanent tissue consist of more than one time of cell and all are differeniated but meristemic tissue consist of undiffereniated cells.
Meristemic cells are simple but permanent cells are complex in nature.
Meristamic cell responsible for primary and secondary growth and permanent tissue helps in overall growth of plants
Explanation:
Choice B is correct.
Solar energy charges the battery or cell; it is then powered through the wires and light comes and heat.
But if the lamp they are talking about doesn't have wire the choose C.
But I am certain it is B
Answer:
The correct answer is: B. If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children.
Explanation:
- The inheritance of genes from the parents to the offspring is mediated by the germinal cells or sex cells or gametes of the parents.
- The genetic material present in the somatic cells of the parents are not transmitted to the offspring.
- In the given case, the man who develops lung cancer generates some tobacco smoke induced mutations in some of the cells of his lungs.
- The cells of the lungs are type up of somatic cells. Hence, any mutations in the genome of these cells will never be transmitted to the offspring.
- Therefore, the children of the man will never become prone to develop lung cancer due to development of mutations in the lung cells of the man.
- However, if the man has inherited any mutation from his parents which can increase the risk of development of lung cancer, then these mutations will be present in his germinal cells and also in some of his gametes.
- Now, if a child is born due to the fusion of the the maternal gamete with one of these mutated paternal gametes, there is an increased chance of developing lung cancer in the child, irrespective of the fact whether he is a smoker or a non-smoker.
