6. In Chicago "Smiling Gus" Winkler met up with some of Chicago's most famous gangsters. They included:
viktelen [127]

Answer:

Al Capone, Fred "Killer" Burke, and Bugsy Moran.

Explanation:

Augustus "Smiling Gus" Winkler was a big-time gangster who had his fingerprints surgically altered so as not to be identifiable through fingerprint technology. He was part of Eagan's Rats gang and would participate in some of the most notorious crimes such as the St. Valentines Massacre in 1929.

When he moved up north, he met up with some of the world's famous gangsters like Al Capone, Roger Touhy, Fred Burke, and Bugsy Moran. But in 1933, to secure himself, he turned evidence against his friends and accomplices. But he was not to be safe for long, for he was gunned down by unknown assailants rumored to be ordered by Frank Nitti on October 9, 1933.

Match the term on the left with its definition on the right.
noname [10]

Answer:

1. Eutrophication  - When fertilizers, animal waste, or sewage flow into waterways, causing algal blooms  and depriving other organisms of oxygen .

2. Biological  augmentation  - Adding natural predators to a damaged ecosystem .

3. Ecological  footprint  - The number of natural resources used to support an individual's lifestyle .

4. Biodiversity  hotspot  - Areas of high biodiversity that have been significantly impacted by human activities .

5. Acid  precipitation​ - The result of pollutants reacting with water in the air to form sulfuric acid, which falls  back to the earth's surface in rain, snow, sleet, or fog .

Explanation:

  • Eutrophication

The enrichment of an aquatic ecosystem by minerals and nutrients caused by animal waste, human activities like sewage flow, farming, etc that lead to fertilizer runoff into waterways causing algal blooms which results in the oxygen depletion of the aquatic ecosystem. Algal blooms block sunlight from getting into the water and deprives other organisms of oxygen, thus harming the plants and animals in the ecosystem. Some species of algae produce toxins that are harmful to human or marine life.

  • Biological augmentation

It is the most efficient way to clean and restore nature and natural resources like water bodies, soil, etc by decomposing pollutants and adding essential materials to a damaged or degraded ecosystem with the use of organisms such as bacteria. Examples include increasing the available nitrogen in soil by nitrogen-fixing plants, wastewater treatment, cleaning of ponds and lakes by adding bacterial cultures, enzymes, etc.

  • Ecological footprint

It measures the number of natural resources and how fast they are consumed to support people or an economy and also the waste generated, i.e., measurement of human demand on nature. For the calculation of ecological footprint, the usage of certain categories of productive surface areas such as forest area, cropland, fishing grounds, grazing land, built-up land, carbon demand on land, etc is tracked. Based on this information, the quantity of natural resources we have and how much of these resources are used is measured.

  • Biodiversity hotspot

It is a biologically fertile region that has a rich distribution of plants and animal species not found anywhere else and is highly threatened with destruction by human habitation. Examples of biodiversity include the Andes Mountains tropical hotspots, New Zealand archipelago, forest habitats, etc.

  • Acid precipitation​

It is any form of precipitation including rain, dust, fog, snow or hail with acidic components that possess a pH of about 5.2 or below, such as nitric or sulfuric acid that fall to the ground from the atmosphere. The fossil fuel emissions such as sulfur dioxide, nitrogen oxide, etc react with the water molecules in the atmosphere to produce acid precipitation. By reducing fossil fuel emissions, the effect of acid precipitation can be reduced.

A pharmaceutical company claims that it has developed a drug that will decrease the likelihood of seizures in patients with epil
Paraphin [41]

Answer:

B

Explanation:

This ensures that the research is corroborated by other scientists and is peer-reviewed hence increasing the veracity of the findings. This also ensures that conflict of interest is addressed whereby the findings by the company may appear to be compromised or biased because such a finding would be in favour of their own needs (such as financial gain).  Peer review in such case is  even more important because it involves humans subjects and ethics are paramount in healthcare research.

Organisms that live in the _________ must be adapted to little or no rain and to extreme temperatures.
umka21 [38]

Answer: DESERT

Explanation:

Adaptation can be defined as the modification in the form, structure, function and behaviour of organisms in a habitat which enables them to live successfully and reproduce.

Desert is one of the types of the world biomes that is characterized with little or no rain and to extreme temperatures. Organisms, which includes plants and animals, must show some level of adaptation to able to survive the harsh environment.

The type of PLANTS which can survive in desert environment are called the XEROPHYTES. They show the following adaptations:

--> The roots are well developed: they grow down to great depths and branch extensively in order to absorb water

--> they possess swollen stems which contains water storage cells.

--> they have reduced leaves, for example in cacti in the form of spines, which helps to reduce water loss through transpiration.

The type of animal that survive in desert environment spend the hot dry seasons in a sleep-like torpid state called aestivation. This is so in order to avoid the heat. Their body size is usually small and less bulky: greater surface area in relation to body volume, thus enhancing heat loss from the body.

Organisms that live in the _________ must be adapted to little or no rain and to extreme temperatures.
