The nervous system is the most important body system and the heart is the most important muscle
Hey there!
Increasing ventilation in enclosed spaces would for sure improve indoor air quality.
Keeping pets indoors, using darker paint on all interior walls installing sunscreens in all windows would not help improve indoor air quality.
I hope this helped! :-)

According to Ainsworth's maternal sensitivity hypothesis, a child's attachment style is influenced by the way their mother interacts with them.
- 'Sensitive' mothers react appropriately to their children's moods and feelings as well as to their requirements. Children of sensitive mothers are more likely to form strong attachments.
- Contrarily, women who are less attentive to their child, such as those who respond poorly to the child's needs or who are impatient or ignore the child, are more likely to have children who have insecure attachments.
- The findings of Ainsworth (1971, 1978) offered the first empirical support for Bowlby's attachment theory.

Answer:
When skeletal muscles are trained by adding physical stress to them, this is called progressive resistance training (PRT).
Explanation:
During PRT, muscles are exercised against an <em>overload or resistance</em>; the overload is gradually increased in order to allow muscles to adapt. This allows for progressive strength increases over time.
Muscle fatigue is defined as a reduction in the ability to produce force due to exercise. This comprises:
- peripheral fatigue- due to changes at the junction between motor neurons and the muscle.
- central fatigue- caused by a reduced capacity to use voluntary force in relation to the capacity to use involuntary force
- and muscle damage- this is associated with several issues at the cellular level such as disrupted membranes and cytoskeletons; and tissue damage via torn muscle fibers, and collagen.
Overall, these may affect muscle fiber activation and the amount of force they are capable of producing- i.e. sustained strength. However, muscle fatigue can be greatly reduced via the maintenance of PRT. Also, apart from strength gains, PRT is <em>used for weight loss and muscle building</em>; common tools used in PRT include <em>free weights, elastic bands and exercise machines. </em>
