Answer:

1. Picky eating; food jag

2. epiphyseal plates

3. bone mineral density (BMD)

4. obesity

5. food insecurity

6. life expectancy

7. arthritis

8. congregate meal

Explanation:

Picky eating is a behavior in early childhood when they refuse to eat certain foods and only want the same foods, while food jag is when a child only eats a small group of foods, meal after meal. The epiphyseal plate is a specialized layer of hyaline cartilage where chondrocytes (i.e., the only cells found in healthy cartilage) proliferate and differentiate during longitudinal bone growth. Arthritis is an inflammation of the joints caused by different reasons (e.g., injury, genetic causes, infections, immune system dysfunction, etc), whose risk increases with age. Bone mineral density (also known as bone density), is the amount of mineral in bone tissues, being the best manner to measure bone health. Obesity can be defined as an excessive amount of body fat that presents a risk to health. Over the past 30 years, the prevalence of obesity has doubled in children and tripled in adolescents, representing a serious health problem (especially in developed countries). Moreover, food insecurity is a social condition of limited access to food for individuals in a household to live an active, healthy life, which can be used as a metric of how many people cannot afford food. Life expectancy is an estimation of the number of years a person can expect to live in a given country/region. Life expectancy around the world has increased for nearly 200 years especially due to medical progress and access to food. Finally, a congregate meal refers to a healthy meal provided to anyone age 60 or over that encourages older adults' social connections with other persons at the meal sites.

Iron-55 has a half-life of 3 years. How much of a 40 gram sample will remain after 12 years? A. 0 grams B. 4 grams C. 2.5 grams
Readme [11.4K]

Answer:

\boxed {\boxed {\sf C. \ 2.5 \ grams }}

Explanation:

We are asked to find how much of a 40 gram sample remains after 12 years.

Iron-55 has a half-life of 3 years. Therefore, after 12 years, 4 half-lives have been completed.

  • 12 years/3 years = 4 half-lives

Every time a half-life is completed, half of the sample's mass decays. Remember we start with a 40 gram sample.

  • 1 half- life: 40 g / 2 = 20 g
  • 2 half-lives: 20 g / 2= 10 g
  • 3 half-lives: 10 g / 2 = 5 g
  • 4 half-lives: 5 g / 2 = 2.5 g

There is also a formula that can be used to solve this problem.

A= A_o(\frac {1}{2})^{\frac{t}{hl}

Where A₀ is the initial amount, t is the time, and hl is the half-life.

We know 40 grams is the inital amount, 12 years is the time, and 3 years is the halflife.

  • A₀= 40 g
  • t= 12
  • hl= 3

A= 40 \ g (\frac{1}{2})^\frac{12}{3}

A= 40 \ g (\frac{1}{2})^4

A= 40 \ g * 0.0625

\bold {A= 2.5 \ g}

After 12 years, <u>2.5 grams </u> of Iron-55 will remain.

you may have read about alkaline diets that claim that you need to only eat alkaline foods in order to remain healthy according
hram777 [196]

Answer:

Mechanisms are activated where it is sought to lower the amount of free protons in the blood, that is, to reduce acidity, these mechanisms work between two large systems, the receptor system, the respiratory system and the renal system.

Explanation:

When a metabolic acidosis is entered, either by a food, or by a disease or even an intense physical activity, the lungs seek to generate hyperventilation, to increase the concentrations of oxygen in plasma and absolutely decrease the carbon dioxide concentration, thus not the blood becomes even more acidic.

On the other hand, the digestive system together with the sensory system, will warn this proprioception of the acidity of the plasma and will promote the dilution of these acids with a solvent, which is water, promoting the sensation of thirst.

Finally, the kidneys will seek to retain all the alkaline solutes to neutralize the physiological internal pH, and will release through the urine and the channels of acidic compounds, the products or acid metabolites to the external environment, that is, acid urine excretion.
