i just finish that test
Answer:
scientist has brought together all the research on the subject and found that, from bees to birds to wolves, many animals have an ability to process and represent numbers arguably a form of counting.
Explanation: What's more, the new study suggests that this mathematical prowess helps animals stay alive in a brutal world. Such a finding extends our knowledge of animal cognition, a field that has grown exponentially in recent years.
The energy produced from flow of water or "Hydro-power" is different to energy produced from iron, petroleum and coal as it is a clean and renewable form of energy. Hydro-power is derived from the kinetic energy of the natural flow of water like in the case of a water mill whereas the other forms listed require combustion of the fuel source that produces harmful gases leaving a negative impact on the environment. Also, hydro-power is one of the cheapest forms of energy production.
However, it should be noted that large-scale production of electrical energy from flowing water known as "Hydroelectric Power" uses man-made dams to store water in lakes as a source of potential energy. These dams can also have a negative impact on the environment as the natural flow of water is restricted. Some scientists also suggest that the construction of a dam leads to an increase in the number of earthquakes in and around the area of construction.
Answer:
A RISK is the chance that someone or something could be harmed by a hazard.
Explanation:
Risk is the <u>probability of experiencing harm or an adverse side effect from exposure to a hazard</u>, may it be from the workplace, environment, or property.
Hazard is anything that may be a <u>source of possible harm or damage</u> to an individual or property.
Risks within the workplace are assessed to prevent workers from possible exposure or damage, this is called <u>Risk Assessment Control</u>. Here, the <u>likelihood of a hazard occurring is determined</u>.
An example is medication errors when the nurse/s are overworked.
<em>"Overworked nurses are 15 times (for example) more likely to commit medication errors than fully-rested nurses."</em>
The likelihood of developing such errors depends on multiple factors like:
<em>"Too much work load"</em>
<em>"Huge number of patients"</em>
<em>"Lack of manpower"</em>
Answer:
Genetic diversity is important because it allows organisms to adapt to changes around it, thereby preventing extinction- <u><em>True</em></u>
Explanation:
Genetic diversity is one of the main reasons that brings about the survival of an organism in an ecosystem. As alleles of a gene assort independently during gamete formation, this phenomenon brings about genetic diversity. The genetic diversity allows organisms with better traits to survive and hence, they become better adapted to live in a habitat. As the organisms with better traits survive, extinction of species becomes lesser through this phenomenon.
