The answer is; 1
Most of the photosynthetic organisms are located in the epipelagic zone of the oceans where sunlight can penetrate before diffusing and becoming too weak to support photosynthesis. The epipelagic zone is filled with plankton. When this plantkon die, they begin to sink slowly to the bottom of the ocean. These plankton are food for small fish. These small fish are food for bigger fishes. This is how an ecosystem is sustained in the deep dark oceans.
dirtier water
B.
straighter
C.
wider
D.
more curves
Answer;
D.more curves
Explanation;
-Deposition is the process of the eroded material being dropped that takes place when a river loses energy. The loss of the river energy is attributed by factors such as reduction in rainfall, increase in evaporation, friction close to river banks and shallow areas which leads to the speed of the river reducing and thus the energy reduces. Deposition process would make a river change in more curves.
B. increased energy
C. increased particle collisions
The correct reason behind the increased rate of the reaction with the increase in these parameters is the increased collisions between the particles.
Option C.
Molecules that take part in a chemical reaction are present in a common medium. This medium contains all the molecules and the enzymes required for the reaction. The reaction that takes place in the medium is initiated by the collision between the reactant molecules which dispose into the reaction. Thus, increasing the rate of collision between the molecules increases the rate of the reaction.
Increasing the temperature increases the kinetic energy of the molecules which in turn increases the rate of collision.
Increase in the pressure reduces the volume, thereby bringing the molecules together, increasing collision.
Increase in concentration increases the number of molecules per unit volume, thereby increasing the rate of collision.
Answer:
increased particle collisions
Explanation:
Answer:
When an electron absorbs energy, it jumps to a higher orbital. An electron in an excited state can release energy and 'fall' to a lower state. When it does, the electron releases a photon of electromagnetic energy.
Explanation:
Majorly population growth is affected by birth and death rates and also on the migration, immigration factors it also depends on the favourable condition.
like if environment is favorable enough food, living space, no competition, no lethal diseases and also temp. water availability) than growth will be good, if not than growth will be less.
These density-independent factors include food or nutrient limitation, pollutants in the environment, and climate extremes, including seasonal cycles such as monsoons. In addition, catastrophic factors can also impact population growth, such as fires and hurricanes.
Fertility Rate
The factor which affects the growth of the population in the biggest way is the fertility rate. The fertility rate is typically measured by the number of children per one woman of child-bearing age. If the fertility rate is larger than 2, the rule of thumb is that the population should rise, as there are more children than their parents. On the other hand, if this ratio is below 2, the population of the region may be destined for a decline.
Mortality Rate
A key factor affecting the growth of the population is the death, or mortality, rate. Just as the birth of new people increases the population size, deaths decrease it. The factors that affect the mortality rate include the availability and affordability of quality health care and lifestyle habits – for example, whether they smoke or do physical exercises regularly.
Immigration and Emigration
Cross-border migration is the act of people moving from one country to another. It affects the population size of both the host and destination countries. Emigration is caused by a number of factors, such as fleeing war, finding education, seeking new jobs or joining family members. When a person emigrates from a country, its population shrinks. When someone moves to a country from another place, it is known as immigration. Whether or not a person is allowed to immigrate is controlled by the country that will host this person.
