Explanation:
Uses/Advantages of Renewable Energy
It can be used to generate electricity e.g. hydro energy
It is used for cooking at homes e.g. wood/biofuel.
It enables the growth of our crops e.g. solar energy.
It facilitate movement of people and goods from one place to another e.g. fuel, diesel, natural gas.
Renewable energy lasts a life time
Renewable energy is clean and does not cause pollution
Renewable energy is cheap once it is fully installed
Misuses/Disadvantages of Renewable Energy
It can be used to produce nuclear weapons e.g. atomic bomb
It can cause flooding through overflowing of dams
Wind can be disastrous e.g. storms
<span>jeremy's SUBSTANCIA NIGRA is producing less DOPAMINE than what it needs to.
Substancia nigra is a "black substance" located in the midbrain. When there is the death of dopaminergic neurons in the substantia nigra, the quantity of dopamine decreases, causing Parkinson symptoms. With time passing, the fewer neurons Jeramy will have and those symptoms will become more severe, that is the reason why is smoking more. The nicotine from cigarettes help modulate dopamine transmission and so, to reduce some symptoms.</span>
Answer:
C. The songs will become more similar to each other.
Explanation:
To answer this question, first, you need to remember that both populations belong to the same species, so they can mate because there is no reproductive barrier. The only limiting physical factor impeding individuals of both groups to cross was the piece of land before the land got wetter. So once populations got together, individuals can easily mate.
One population´s males exhibit a courtship song that slightly differs from the one of the other group. This difference has a genetic basis. But females hardly notice the difference. All of them prefer loud frogs to quieter frogs, independently of the population to which they belong.
So when the two populations get together, individuals get mixed. Females do not recognize males of their group, and during the breeding season, all females will mate the most with louder males of any of the population. So females from population A might mate with males from population B, and females from population B might mate with males from population A. So after mating season, there is also a genetic mixture between populations.
The new generations will carry elements of both genotypes. So males´ songs will be even more similar to each other. Songs will become more similar to each other because individuals of both populations are mixed and mated, and their genes intercrossed, producing new individuals with genes of both populations.
In exponential growth, the growth rate of population per capita remains the same in spite of the size of the population, thus, resulting in the population to grow faster and faster as it gets bigger. However, in nature, the populations may grow exponentially for certain time duration, and they eventually get restricted due to limited availability of resources.
In the graph, it is evident that from 1950 to 1990 there is exponential growth, signifying that the fish exhibited almost optimal conditions of living. However, in 1990 the population started to decline steadily, demonstrating an extreme lack of resources or enhancement in predatory species.
The expected e heterozygous phenotype would be orange.
Codominance is a type of non-Mendelian inheritance in which both alleles of one genotype are simultaneously expressed. So, in this example if allele A is responsible for red flower color and allele a for yellow flower color, Aa genotype (both alleles) will give both colors (red and yellow mixed together give orange).
