In the u.s., about what percentage of all food expenditures is now accounted for by meals eaten out?

1 answer:

8 0

<span>Eating away from home is playing an increasing large role in the diet and the household budgets of American families. Back in 1970 approximately 26 percent of all food spending was on food away from home; by 2012, that amount had risen to 43 percent. The increase can be attributed to a greater percentage of women employed outside the home, more two-earner households with the resulting higher incomes, as well as more affordable and convenient fast food outlets. The downfall of this statistic is the contribution all that fast food makes to higher levels of obesity and lower dietary nutritional quality.</span>

Answer:

Experiment 4. Relaxed, the drug will stop the calcium so that it does not act on the troponin

Experiment 5. Contraction: In order for the muscle to relax, the actin and tropomyosin union must occur.

Experiment 6. Relaxation: the release of the actin-myosin complex occurs with consumption of ATP, thus it slides and generates contraction, by adding a hydrolyzable analog, this reaction is avoided giving rise to a prolonged actin-myosin binding which leads to relaxation while last effect.

Experiment 7. Ca2 + Contraction is very necessary so that during muscle contraction troponin can be extracted.

An animal trainer is conditioning an elephant to startle at the sound of a trombone. Every time she plays the trombone, she then

ANTONII [103]

Answer:

The correct answer is option D, that is, the elephant will not react.

Explanation:

A kind of behavior that comprises a stimulus-response, which is distinct from the natural one is termed as conditioning. It is a kind of learned behavior. It is a kind of learning where the efficacy of stimulus enhances while provoking a response. When the presentation of two stimuli is done at a suitable time and with appropriate intensity, then one of them will be able to provoke a response that resembles the other one.

In the given case, the mouse and the trombone are termed as unconditioned and conditioned stimuli. When a conditioned stimulus is demonstrated in a context of classical conditioning, it will result in the non-predication of the coming unconditioned stimulus. The conditioned response will get to cease slowly and will eliminate the conditioned fear. Thus, in the given case, the elephant will fail to react towards the trombone subsequently.

pentagon [3]

Answer:

Plastic is made from petroleum oil.

Explanation:

A faucet can simply be described as a tap or valve through which the releasing of a certain liquid can be controlled. Whereas a plastic is made from non-renewable resources such as petroleum oil. Also, the plastic cannot be properly degraded from the Earth after using it. Hence, drinking water from a faucet is more beneficial then drinking water from plastic bottles.
