Answer:
Hydroponics solves the problem of unavailability of water in those arid and dry regions
Explanation:
As rightly stated in the question, hydroponics is a practice that involves the culturing of plants without the need for soil. Hydroponics procedure make use of a moisture-containing solution filled with nutrients.
This procedure of hydroponics, however, comes with some disadvantages but one major effectiveness it has in arid or dry regions is that it SOLVES THE PROBLEM OF WATER UNAVAILABILITY. When it comes to farming practice using soil, constant water supply is an unnegotiable criterion because water is needed for the growth of plants in the soil.
However, in arid regions, which are usually very dry due to lack of rainfall, the practice of hydroponics can substitute for soil farming in order not to cause food scarcity.

Answer:
Density-dependent factors are defined as the biological factors which are utilized by the population as a resource for example- food and shelter. Charles Darwin uses the concept of density-dependent factors in his Theory of Evolution to show how it affects population growth and mortality.
Charles Darwin used factors like competition, predation, and parasitism in his Theory of Evolution. He explained that habitats are limited by space and resource availability, and only the fittest organism will survive the competition.
Predator-prey relationships create density-dependent limiting factors and balance the ecosystem with limited organisms. If predators will increase in an ecosystem it will decrease the population of prey and after a certain time there will be a shortage of food as they are limited resources.
A. The concentration of water should be higher on the outside because it allows water to slow into the cell to balance the concentration.
Answer:
Explanation:
Research published on January 7 in the journal Nature Genetics shows that identical twins differ by an average of 5.2 genetic mutations. The authors argue that these small differences between twins' genetic code could change how scientists study human development.
