Answer:
False
Explanation:
Lysosomes are membrane-bound vesicles that recycle waste products. They contain digestive enzymes that breakdown waste and recycle the components in the cell. For example, old cellular organelles, viruses or bacteria, large biomolecules.
They might sometimes contain DNA, but not always.
Answer: <em>The reaction is an example of a metathesis reaction, which involves the exchange of ions between the Pb(NO3)2 and KI. The Pb+2 ends up going after the I- resulting in the formation of PbI2, and the K+ ends up combining with the NO3- forming KNO3.</em>

Answer: B. Take short showers instead of baths.
Explanation:
The water is the most important non-living environmental factor which is the main requirement for survival of every living being. Even though water is a renewable resource which can be replenish by the mode of water cycling in nature but with the increase in the global population the demand of freshwater has increased. Also with the increase in the causes and sources of water pollution the levels of freshwater sources are decreasing. Therefore, the issues of water conservation should be taken into consideration.
According to the given situation, if an individual needs to conserve water, take short showers instead of baths is the correct option because of the fact that short showers will prevents the wastage of large amount of water which could be wasted while taking baths.
Answer:
The correct answer is - 0 m/s.
Explanation:
In this position-time graph or distance-time graph, there are three different part that shows three different velocities one in increasing as it moves from a lower position in relative to time and one is stationary and the third is decreasing.
'Straight lines' on a distance-time graph suggest that the movement of the object is constant. During 'Part B' of the journey the object travels 0m in 3s. It is stationary for 3 seconds so the velocity will be zero as well.
