I would say Option B
Explanation:
A controlled experiment is where you have two or more independent variables, that way you have an experiment to compare results with.
Answer:

- Physical: high temperatures and noise.
- Environmental: earthquakes
- Chemicals: toxic substances such as lead
- Biological: hospital contamination
- Ergonomics: bad posture
- Psychosocial: relational conflicts
Answer:
0.00508368 grams
Explanation:
From the question we are told that the daily allowance for infants and children is 8.00 × 10⁻⁶ mole of copper per kiogram of body weight.
Since this value is given in moles, we have to convert it to mass
Molar mass of a compound = mass in grams / no of moles of the compound.
So, Molar mass of copper = 63.546
No of moles of copper per kg = 8.00 × 10⁻⁶ mole
63.546 = mass/ 8.00 × 10⁻⁶ mole
Cross multiply
Mass of copper per kg body weight = 8.00 × 10⁻⁶ × 63.546
= 0.000508368 grams
Hence, the daily allowance of copper required for infants or children per kg of weight = 0.000508368 grams.
For a 10 kg infant this is calculated as:
If 1 kg per weight of an Infant = 0.000508368grams
10 kg =
We cross multiply
10 kg × 0.000508368 grams
= 0.00508368 grams.
Therefore, the mass of copper required per day for a 10 kg child is 0.00508368 grams
Answer:
Altered states of consciousness
Explanation:
In health and medicine, an altered state of consciousness is defined as any state of awareness that significantly differs from a regular waking awareness state (without actually being unconscious). In other words it refers to a significant deviation from a regular waking awareness state.
When someone has a stroke or any other form of brain damage, they experience low levels of awareness that significantly differ from the regular waking awareness state, therefore, this would be an example of altered states of consciousness.
Answer:
.25 (1/4) x 42 (kg)= 10.5ML
Explanation:
Convert kg to lbs by diving the lbs by 2.205.
Then multiply your kg by .25 and there's your answer.
