A man who heavily smokes has developed lung cancer. The tobacco smoke has caused mutations in some of the cells in his lungs, making them unable to stop reproducing and dividing. He is worried that his children, none of whom smoke, may have inherited the lung cancer from him. Under what circumstances might his concern for his children be justified? If his smoking had already mutated the DNA in the cells in his lungs at the time his children were conceived, the mutations would have been passed to his children. 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. If the mutation resulted from the duplication of a gene in his lung cells, his children would be at greater risk than if it were caused by a base pair substitution. If the smoke had caused multiple different mutations in his lung cells, it would be more likely that one or more of the mutations would be passed to his children.

Answers

Answer 1

If he inherited a mutation that made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children is the circumstance that might his concern for his children be justified.

What do you mean by Mutation?

A Mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism.

Gametes of germline cells play an important role in the inheritance of mutation from parents to their offspring, which means that if a mutation has occurred in an egg or sperm cell, it will be more chances that the offspring carry mutated DNA.

Therefore, it is well-described above.

In north carolina, demand for fresh water has increased dramatically. one of the main reasons for this is increased water use for agriculture. respond to the following in 3–5 sentences:

relate one effect of agricultural water use on north carolina's river basins.
relate one conservation strategy that would reduce the effect of agricultural practices on water quality.

Answers

Agricultural practices relating to irrigation have the tendency to reduce the water level of river basins.

What are the effects of irrigation agriculture on river basins?

Irrigation agriculture requires that crops are watered artificially and this requires a water source. Hence, waters in river basins suffer and this leads to a reduction in their levels.

Water quality is impacted by agricultural practices such as the use of agrochemicals and fertilizers. Agrochemicals are washed into water bodies and this impacts biodiversity life in water.

One conservation strategy to reduce the impact of this kind of agricultural practice would be to practice organic farming. A farming practice that is devoid of using agrochemicals or the ones that are not poisonous to biodiversity and are biodegradable.

In Madagascar scientists have discovered a moth, xanthopan morganil praedicta, that has a 30.5 cm proboscis and feeds from and pollinates Darwin's orchid, angraecum sesquipedale. The orchid has a nectar - producing tube that is 27.9 cm long. How is the moth's proboscis size an adaptation for its environment?

Answers

The size of the proboscis helps the moth to consume the food (nectar) easily from Darwin's orchid.

What do you mean by Adaptation?

Adaptation may be defined as the process of modifying one's characteristics to better suit a situation and survive more efficiently.

The size of the tube that produces nectar is just 27.9cm long, while the length of the proboscis of a moth is 30.5cm. It easily consumes the nectar and gets energy for survival as well as reproduction.

Therefore, the size of the proboscis helps the moth to consume the food (nectar) easily from Darwin's orchid.
