1. I<span>f immigration and emigration numbers remain equal, decreased birth rate could cause a slowed growth rate. Decreased means that something is getting lower, so I guess that means that growth rate is also being slower than usual.
3. A</span><span>s resources in a population become less available the population reaches carrying capacity. Carrying capacity has to do with the total number of entities in a population.
4. W</span><span>hen the exponential phase of logistic growth curve of a population ceases, population growth begins to slow down. When something ceases, it stops, which means that other processes also stop or become slower.
5. The most likely reason that a population of mice in a farming area suddenly increases is that more food is available as grain is harvested. This means that there is more food for mice as well, which is why they tend to settle in these areas. </span>
Answer:
C
Explanation:
An ecosystem food chain always starts with producers
Consumers then consume the energy from producers (prey on them)
Decomposers are organisms which break down dead material and provide energy to the environment for which producers can use which creates a looped cycle
Answer:
All are methods to separate mixtures
Explanation:
<em>A mixture consists of 2 or more substances that are mixed physically but not chemically. Hence, mixtures can be separated by any physical separation means which include but not limited to filtration, distillation, sieving, magnetization, and evaporation.</em>
Filtration is usually used to separate suspended particles in a liquid using a membrane of a filter paper. Distillation is used to separate miscible liquids with varying boiling points by evaporating and condensing them back at their respective boiling points. Sieving is used to separate mixtures with varying particle sizes of individual components.
Magnetization is usually used to separate mixtures with, at least, one component with magnetic property. Evaporation is used to separate dissolved solids from liquids.
<u>Hence, all the methods listed are used to separate mixtures.</u>
Two key factors are involved in people accepting the drinking of tap water that comes from the treated wastewater:
1. Economic strength of the country: The country that has the wealth to develop and use technologies that can treat and purify the wastewater to make it available for drinking will make it possible for the people to accept it. The country may subsidise this kind of water to increase its use and popularity among its citizens.
2. Social acceptance: People should understand that they are drinking pure water and not wastewater. The change in mentality of people will promote its consumption.
