A) The answer is 0.1/year.
The reproductive rate for the population can be expressed as:
(number of births - number of deaths)/number of individuals = (55-5)/500 = 50/500 = 0.1
b) The answer is exponential growth.
The exponential type of population growth occurs when resources are unlimited. When there are no limiting factors, population exhibits exponential growth. If every year population has mentioned reproductive rate, that means it is not limited by any factor (food, space, etc.). Thus, it must be exponential growth.<span> </span>
Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond.
Answer:
An ionic bond can be formed after two or more atoms loss or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons. Ions with opposite charges will attract one another creating an ionic bond
Answer:
Blood vessels are the channels or conduits through which blood is distributed to body tissues. The vessels make up two closed systems of tubes that begin and end at the heart. One system, the pulmonary vessels, transports blood from the right ventricle to the lungs and back to the left atrium.
Explanation:
Natural selection refers to the phenomenon by which the species in a population possessing the tendency to get adapted in a condition enhance in numbers in comparison to those who exhibit fewer adaptation capacities over a number of generations.
In other words, it can be stated as the non-random and differential development of distinct genotypes function to sustain favorable variant and to eradicate less favorable variants. Some of the conditions are required for the process of natural selection to take place.
These are heredity, reproduction, variation in individual characters, and variation in the fitness of organisms among the members of the population. If the conditions are met, then the phenomenon of natural selection occurs by default.
