Which of the following is NOT a source of point-source pollution? a. trash dumping c. pesticide runoff b. sludge dumping d. oil spill

Answers

Answer 1

Answer:

Answer: c. pesticide runoff

Explanation: A point source pollution is the pollution which is caused by the pollutants whose source of origin can be traced back and further pollution can be prevented. A non-point source pollution is the one which cannot be traced back to it's origin and hence, cannot be prevented from further pollution. Trash dumping, sludge dumping and oil spill are the examples of point source pollution. But pesticide runoff is the example of non-point source pollution. A surface runoff will wiped off the pesticides from their surface and discharge them to the water body the source of origin of these pesticides will remain undetermined.

Plants have male and female gametes (sperm and ovaries) and can reproduce sexually.

Answers

Not really. Plants can have a male and female pollination through Stigma and Style but they do not have gametes and sperm/ovaries.

So yes they can (kind of) reproduce sexually just without gametes and gonads (which is what sperm/ovaries are)

In which of the following states can water Not exist? A. liquid B. gas C. solid D. none of the above

Answers

Water exists in all the statesofmatter which are the solid, liquid, and gaseous states.

What are the states of water?

Water is known to exist in three different physicalstates. These are the solid state as ice, the liquid state as water itself, and the gaseous state as water vapors.

Under the conditions of standard temperature and pressure, the freezing point of water is zero degrees Celsius. At this temperature, water starts to freeze and attains a solid form which is in the form of ice. The density of ice is lower than the density of water because of the fixed intermolecular distances in ice.

Under the conditions of standard pressure and temperature, water exists in liquid form between temperature ranges of zero to a hundred degrees Celsius. Liquidwater is essential for all organisms. It functions as a universal solvent.

At a temperature above hundred degrees Celsius, the intermolecular integrity between the molecules of water starts to decrease and ultimately breaks completely. In these conditions, the water turns into vapors.

Therefore, water exists in all the states of matter which are solid, liquid, and gaseous states.
