The act of strengthening the muscles of the abdomen and torso is <u>core strengthening.
</u>
Explanation:
The core is the central part of the body comprised of about 35 (major and minor) muscle groups which connect to the pelvis, spine and hip area. These can be broadly grouped as the abdominals, back extensors, hip, and lateral trunk muscle groups.
The core area is the centre of gravity and stability for all bodily movements.
Strength of core muscles is very important especially to athletes and sports persons. Weakness of core muscles leads to general body weakness and fatigue, muscle injuries like sprains, less endurance and power, back pain, and poor posture.
Core strengthening exercises are done to train the core muscles and strengthen them and work in harmony for better body balance, stability, and movement. Core strengthening exercises include crunches, plank, L-sit, sit-ups, push-ups etc
Answer:
B) Category B
Explanation:
Centers for Disease Control and Prevention along with US Department of Homeland Security has classified biological agents into three categories based on the level of mortality, ease of spreading and the level of preparedness required to deal with them. These biological agents are mostly microorganisms which if not controlled can create a havoc on a big scale.
Category B consists of agents which have moderate potential for dissemination. These are the agents which effect food and water quality and lower down their safety levels. They moderately affect the population and mortality rate is low. However, uncontrolled they can spread and effect many people. For example, salmonella and zika.
