Ever heard that kids are naturals when it comes to learning a language? Or maybe you know someone who gets easily discouraged from attending a second language course because they say they’re too old. Whatever you might have heard about this, whether you can remember or not, I’m positive it’s related to one of the most famous linguistics debates, which has been around since the 1960s.
Answer:
Darwin proposed the theory of natural selection to explain the process of evolution. According to Darwin’s theory of natural selection, all organisms have the potential to reproduce limitlessly irrespective of the fact that each species maintain a constant density over time. However, the struggle for existence, i.e. the competition among individuals for available resources to survive and reproduce, put a check on species density (D) and maintains it at a constant level (B). Survival of fittest is unequal ability of individuals to survive and reproduce based on suitability of their inherited characters to prevailing environmental conditions (A). It imparts the reproductive advantage to certain organisms which account for major part of the gene pool of the species. Thus, natural selection favors the individual with survival and/or reproductive advantage over others under existing environmental condition (E). Thus, the correct answer is option C.
Answer:
The correct answer is :
Independent Variable: side of the shower with lemon juice
Dependent Variable: cleanliness of shower
Control: spray of water
Conclusion: lemonade juice have no effect on slime
Explanation:
Independent variable in any experiment is the variable that is changed or manipulated as here side of the shower that is sprayed with lemonade juice is manipulated to see if there is any effect on the cleanliness of shower.
Dependent variable is the variable that is observed or measured to check if manipulated variable or independent variable have any effect on it, like the cleanliness is measured to check if lemonade juice clean the slime of the side or not.
The control is something that remains the same to check the condition or effect that is not changed or can be compared to it. Water spray is control in this case.
The conclusion of this experiment is that there is no effect of lemonade juice on the cleanliness of slime present in the shower

Explanation below
Explanation:
It should be understood that the population growth rate of a particular country can be explained or described as the increase in the number of the citizens of that country.
There are so many factors that contribute to an increase in the number of people of a country. These include influx of people into the country, increase in birth rate and decrease in death or mortality rate.
In this case, the growth rate is usually calculated in percentage, so the growth rate should be around 3.5%.
