Most foodstuffs contain natural, radioactive isotopes : TRUE.
- Radioactivity is, and always has been, present in all foodstuffs to some extent. Recent events have made the general public aware of this and most do not know about radioactivity and radiation.
There are four possible sources of radioactivity in foodstuffs: one natural and three artificial.
- Natural Radioactivity
- Industrial Radioactivity
- Weapons Testing
- 4. Accidents Involving Radioactivity:
Airborne radioactivity mainly consists of nuclides attached to dust particles which settle directly onto the ground or can be washed out by rain. Some radionuclides are gases and these are mainly washed out by rain.
Thus, both vegetation and soil can be contaminated, so radioactive elements remain their in foodstuffs.

Answer:
Erikson’s psychosocial stage of trust versus mistrust shows how the developmental needs of working children are not met.
Explanation:
Erikson’s psychosocial stage of trust versus mistrust shows that very young children, around two years old, need an environment where they can explore and socialize to create a sense of trust, happiness and positive development. Children who do not have the resources to socialize and explore, end up developing a sense of distrust and anxiety, unhappiness, as their development needs are not met. Working children do not have the freedom to explore and socialize, test their childhood ideas and challenge themselves according to the environment around them. These children do not have their senses of trust stimulated and become oppressed and limited, anxious and lacking great abilities to plan and explore ideas. In this case, we can see that the trust versus distrust stage shows how the developmental needs of working children are not met.
Yes
The benefits of the Louisiana purchase outweighed the drawbacks.
Most of the drawbacks consists of fairly unfriendly Indian tribes (but some were friendly), the time it took for people to start moving into the land, and the amount of money needed to pay for the area (which actually almost made the past US broke). The advantages was that the US land size nearly doubled, and they found a variety of new animals and resources, as well as good land for farming. The animals provided food, clothing, and even money from the meat and skin. (Ex. Buffalo).
