The one mile run/walk from the Fitnessgram measures flexibility. Question 4 options: True False

Andru [333]

Answer:

Birth Rate

Now, this might seem very obvious to you, but when babies are born, it results in a population change! Social scientists who study this trend have some key terms, though. First, the fertility rate in a country refers simply to the number of children born. This is different from the fecundity rate, which is the number of children who could be born in a given society. In other words, fecundity is the biological capacity of humans to produce children.

Death Rate

Just as when babies are born, when members of a society die it changes the population. This might be a bit morbid to think about, but scientists refer to this as the mortality rate, which is simply the number of deaths that occur in a society. This is usually calculated by looking at the number of deaths per 1,000 individuals. In the United States, for example, the death rate is 8/1000 people. Just like birth rate, the death rate in a country depends on things such as availability of quality medical care, disease, war, or famine.

Migration Rate

One important factor that accounts for a change in population is migration. At the broadest level, migration refers to movement; it's the flow or circulation of people in societies. There are two kinds of migration: emigration and immigration. Emigration means to leave one's own country for another. Immigration means to enter into a country other than one's own.

Choose one article from a primary scientific literature that uses a microbe as a model organism/system and write a comprehensive

alexgriva [62]

Answer:

The article from a primary scientific literature uses a mycobacterial group as a model organism for researchers to determine where they get their extra nutrients in the hostile environments they infect.

The study, which was supported by the Australian Research Council (ARC) and National Health and Medical Research Council (NHMRC), was published in the ISME Journal.

a. why did the scientist perform the study?

b. What was then hypothesis under investigation?

c. what were thhe major results and did they support or negate the hypothesis?

d. Which Key technique

Explanation:

A microbe as a model organism would be considered as a proxy organism to lead researchers to get the answers on human´s health enigmas due to the fact that several of their facets are similar to ours, so investigations on these model organisms are highly helpful to understand our own biology.

a. This is a study on a mycobacterial group responsible for diseases as tuberculosis, leprosy, Buruli ulcer, and the scientists performed it to determine what this bacteria do or how they obtain the nutrients they need to survive while they are on an adverse setting, which is during the infection.

b. The hypothesis under investigation stated that carbon monoxide consumption was the responsible for mycobacteria to survive, without growth though, but enough to survive.

c. The results supported the hypothesis that an enzyme known as carbon monoxide dehydrogenase gas is what provides mycobacteria with energy for longer periods of time as they might be able to survive inside the human by using carbon monoxide.

d. The technique used by researchers were a considerable amount of mycobacteria cultures on carbon monoxide to observe if the bacteria thrived on it using this gas as an energy source, and cultures without it and observe if the survived.

"When microbial cells are starved of their preferred energy sources, one way they subsist is by scavenging gases such as carbon monoxide," said Monash PhD student Paul Cordero, the co-lead author of the study.

"They breakdown this gas into its fundamental components, which provide the cells just enough energy to persist."

"Based on these findings, we predict that it uses this gas to its advantage to persist inside human lungs,"

"Our immune cells actually make small amounts of carbon monoxide, which the bacterium may be able to use as an energy supply while dormant."

By providing benefits that are appealing to employees, Patagonia demonstrates that they view employees as ________ that create

fgiga [73]

Answer:

E. Human Capital

Explanation:

Human capital is a unique capital, which is the sum of knowledge, intangible assets, health, personality qualities, skills and experience of an employee that can be of economic value both to an individual and their employer.

Providing benefits that are appealing to employees is a form of investment on employees as human capital, which can increase productivity of employees, thereby creating value for the organization.
