Answer: c. the wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.
Explanation:
The wavelength is simply the distance that takes place between two successive troughs fir a particular wave. It is calculated as:
Velocity / Frequency.
From the statement given, the option that is accurate is that the wavelength of both transverse and longitudinal waves is measured parallel to the direction of the travel of the wave.
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.
Patent fingerprints are made by a liquid or powder that sticks to the finger and then transfers to a surface, leaving an easily visible fingerprint behind. Substances that can leave patent fingerprints are ink, blood, dirt, flour, grease, etc.
Renewable energy refers to the provision of energy via renewable resources which are naturally replenished fast enough as being used. it includes e.g. sunlight, wind, biomass, rain, tides, waves and geothermal heat.
The structure of the nucleus is that it has the protons (+) and the neutrons (0).
