Explanation:
the eggs seems to be rotten because when we add enough salt into water the density of water becomes greater than that of egg ,hence the floats and seems to be rotten
I think a change of land use can alter heat distribution patterns and surface water runoff. Surface runoff is water, from rain, snow melt, or other sources of water, that flows over the land surface, and is the major component of water cycle. The change of land use may alter surface water run off that occurs on surfaces before reaching a channel.
Answer:
The correct answers would be natural selection and high genetic variation in the species.
Natural selection refers to the natural phenomenon by which organisms which are better adapted or have survival traits tend to survive and reproduce more in the environment.
It leads to an increase in the frequency of the trait in a population.
Genetic variation refers to the sum total of all the genetic characteristics present in a population. Higher genetic diversity higher are the chances of a population to survive.
Similarly, different sizes of the beaks are the result of high genetic diversity out of which large size beak was favored by natural selection.
Ultimately, the large beak size trait spreads through the population.
A crab is multicellular.
Hope this helps! :)
Answer:
A) can bring economic benefits and food security to many developing regions
Explanation:
Breeding, rearing, and harvesting of aquatic plants and animals to sell them and gain economical benefit is called aquaculture. Aquaculture provide many type of benefits like it helps in increasing the global food production therefore it bring food security to many developing region.
It provides a cheap source of protein to the world population. It creates jobs and helps in increasing the economy of a country because it can bring a large amount of money with a small investment. Therefore the correct answer is A.
