Answer:
1.33 m/s
Explanation:
The formula for Kinetic Energy is given as:
Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.
Re-arranging the above equation and isolating v, we get
Putting values in this equation, we get:
Thus, the object is moving with a velocity of 1.33 m/s
Answer:
D. A and B
Explanation:
Some <em>Apis mellifera </em>bees genetically inherit the hygienic behaviour to remove the dead and diseased larvae from beehives by uncapping the sealed cells. This activity maintains the overall health of the bee colony by protecting it from unwanted pests and pathogenic diseases. Usually both hygienic and non hygienic bees survive well.
Here, in hot summer many bees had perished due to disease and hot climate. Accumulation of dead larvae in hives of non hygienic bees would have invited more pathogens and created infectious conditions in summer. Hence their hives could not survive. Now the remaining hygienic bees will mate with each other and the offspring will have more chances to be born with the hygienic trait. Hence the frequency of alleles determining this trait will increase in this population. This would also be an example of natural selection as hygienic bees were preferred by the nature over non hygienic ones to survive in hot season.
Food, water, shelter, air, sunlight
Answer:
100 beetles are present in per hectare if they are uniformly distributed.
Explanation:
If the population is uniformly distributed, so the population of beetles i. e. 11500 is divided by 115 gives the result of 100 beetles per hectare. If the environment is suitable for the growth of beetles, the carrying capacity of beetle population is about on million per hectare. They grow very fast if there is plenty of water and food is available for beetles but their population decreases when drought occurs in the area.
But anyway, the solution to our problem, the answer to our question is that the stages of stellar evolution, in the correct order, are: a nebula followed by a protostar followed by a main sequence star followed by a red giant and then finally, a white dwarf.
