Answer: 3.

Explanation:

A population refers to the total number of organisms of the same species, that inhabit a distinct area at the same time, and have the capacity of interbreeding. In Kevin´s study, we have three different populations involved: spiders, crickets, and birds.

In determining living standards, productivity plays a key role A. for nations, but not for individuals. B. for both nations and
forsale [732]

Answer:

The correct answer would be option B, For both nations and individuals.

Explanation:

In determining the living standards, productivity plays a key role for both nations and individuals.

Productivity is basically the measure of being productive. When the effectiveness of a productive effort is measured in terms of the output it generates, this is called productivity. For example, we can say that this new machinery will be able to product 40% more units of the product. This means, the effectiveness of the new machinery is 40% more now in terms of its output.

Now in this example, productivity plays a key role for both nations and individuals. When effectiveness of a productive effort increases, it will directly impact the company, employees of the company, the economy of the country and thus the whole nation and their living standards. Productivity helps in generating more GDP for the economy, and thus also helps in the growth.

<h3>What is hunting?</h3>

Hunting is the human practice of hunting, pursuing, and killing wild or feral animals.

There are probably as many reasons to hunt as there are hunters, but the main ones are four: to participate in nature; to have an intimate, sensual connection to place; to take responsibility for one's sustenance; and to recognize our kinship with wildlife.

Humans typically hunt for sustenance (meat) and valuable animal products (fur/hide, bone/tusks, horn/antler, etc.), for recreation/taxidermy (see trophy hunting), to remove predators threatening to humans or domestic animals (e.g. wolf hunting), and to eliminate pests and nuisance animals.

Revolutions happen primarily _____________________________________________________. Select one:
deff fn [24]

Answer:

c. Hierarchical environments where those at the top maintain the status quo out of self-interest.

Explanation:

This is usually the type of environments that give rise to revolutions. One of the most important factors in encouraging a revolution is the presence of inequality. Revolutions most often happen when a group feels disadvantaged and thinks that the system it is living under is unjust. For this to happen, you generally need the presence of a wealthier or more powerful group at the top. Moreover, this group must be exclusive, and interested in maintaining the status quo in order to benefit itself.
