What powers did The Empire of Great Britain have over its people<br>​
zhuklara [117]

Answer:

The Empire of Great Britain had a "global power," which was also known as a "superpower" concerning resources, influences and geopolitical landscapes.

Explanation:

<em>When it comes to international relations, the power of a country or a nation is very important.</em> It is an inherent goal that many people want. It can be used in many situations such as<em> cooperating with other countries, coercing people to follow a rule, securing the nation and developing the nation, etc.</em>

The Empire of Great Britain was considered, together with USA and the Soviet Union, to have a "superpower." Only the strongest nation possess such power. It was able to control millions of people, which then resulted into a great expansion. <em>The reason behind this is that they had a stricter rule than other nations and people followed it.</em> This made them stronger and while they continued expanding, they were able to acquire more resources.

PLEASE HELP IM DESPERATE
Furkat [3]

Answer:

8. D

9. A

10. A

11. C

12. D

Explanation:

8. Natural selection works on variation that exists in the genes of organisms. Antelopes who have genetic variation that makes their legs more muscular are at an advantage because they can outrun predators. This increases the chance that they will reach reproductive age, and be able to pass this advantageous trait onto their offspring. Over time, this selection pressure makes the variant more common in a population.

9. Beneficial traits are those that give a selective advantage. This could be one that helps it outrun predators (like above), avoid illness and death, gives it a reproductive advantage (i.e. more attractive to mates), or makes it better able to digest certain foods, for example. The formation of cancer cells would be harmful for an organism, reducing its fitness and perhaps leading to death. The inability to reproduce would mean genetic info is not passed on to the next generation, and stopping the production of an essential protein would likely lead to death. However, resistance to a virus would help an organism avoid illness and death, improving fitness.

10. Genotypes are what organisms inherit from their parents, i.e. the genetic information that is passed on. However, the way in which different alleles interact and are expressed is the phenotype. If we take the above example, natural selection is acting on the phenotype of muscular legs. If an antelope had the muscular leg genotype but for some reason it was not being expressed (maybe another gene is interfering with it), then the antelope would not have a selective advantage, and natural selection could not be act on the trait.

11. A trait that better suits an organism to its environment will be selected for by natural selection. This is because that organism is more likely to survive due to the trait, giving it a selective advantage. Therefore, if a mutation arose making the giraffe more adapted to the environment, it would be positively selected for, and through evolution would become more common.

12. This is an example of selective breeding, which has been happening for generations. Farmers spot desirable traits, and cross horses with these traits in an attempt to enhance the trait or to ensure it is passed on to the next generation. This is not natural selection, because farmers are making it happen artificially. It is not cloning or recombinant DNA, which are terms scientists use for actually manipulating the DNA in the lab.

Answer:

Celestial microwave radiation found a strange microwave signal causing background noise in the radio telescope. The signal came from every direction. The young universe would have been very hot. The microwave background radiation is the remaining heat from the Big bang.
