Answer:

The correct answer would be - Dd Pp.

Explanation:

As it is given that tall D is dominant over dwarf d and smooth plant Pis dominant over pubescent p so the the genotype of dominant trait that is tall and smooth tomato plants would be DDPP . similarly the recessive trait that is dwarf and pubescent plant would be ddpp

Thus, the cross between these would be -

DD PP x ddpp

And gametes would be - DP,DP, dp, and dp.

So, all the 16 offspring would have Phenotype would be heterozygous tall and smooth and DdPp genotype .

Thus, the correct answer would be - Dd Pp.

Waste management would be the most difficult to reproduce once it runs out. Thus, option "C" is the answer.

<h3>What is waste management?</h3>

Waste management~ includes the activities and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process.

For example, Incineration is the process of burning of solid wastes. It is one of the processes of solid waste management. In this process, combustion of organic and inorganic wastes takes place that leads to the formation of ash, heat and flue gases. Ash is composed of inorganic constituents.

The heat generated during this process can be used to generate electricity. The process is carried out by Incinerators. Incinerators does not completely replace landfilling but it reduces the volume of disposal of wastes.

Thus, option "C" is the answer.
