Answer:
Option (b).
Explanation:
Pulmonary ventilation is the mechanism of respiration in which the oxygen is inhaled in the body and carbon dioxide is exhaled out due to the pressure difference in the lungs and the environment.
The surface tension in the alveoli is decreased by the presence of surfactant. The increase in the surface tension of the alveoli increase the force that will require the additional muscles to work properly.
Thus, the correct answer is option (b).
Answer:
There are three main ways of avoiding the spreading of an invasive plant species via manual control. Manual control techniques include activities such as hand-pulling, digging, flooding, mulching, burning, removal of alternate hosts and manual destruction or removal of nests, egg masses or other life stages. These techniques work best on small populations or in areas where chemicals or motorized equipment cannot be used. Manual control efforts must be persistent and several treatments may be needed to reduce or eliminate the target population. If infestations are too pervasive, manual control may become labor intensive and thus not economically feasible. Digging/Hand-pulling: Remove entire root to prevent resprouting. Usually works best with small or young plants, in sandy or loose soils, or when soils are damp. Smothering: Use mulch, black plastic, carpet, or any other impenetrable barrier to cover target plants for at least one growing season. The effectiveness of this technique can be increased by first cutting the target plants and then smothering them. If dealing with a species that produces clones, be sure to cover all stems of the species. Flooding: This is only feasible where water levels can be manipulated to completely cover cut plants for a period of time. The depth of water necessary and the amount of time cut plants should be covered will vary from species to species.
0-0 because its cannibalism and it's not normal LOL-
i really hope this question is supposed to be a joke
According to the research, she is fearful of becoming obese and her BMI is low by these signs she may be diagnosed with anorexia nervosa.
<h3>What is anorexia nervosa?</h3>
It is a disease characterized by self-induced weight loss, that is, weight loss is caused by the patient herself through a decrease in food intake.
It is considered an eating behavior disorder due to the restriction of food intake, which leads to considerable weight loss that remains below the minimum expected for age.
Therefore, we can conclude that according to the research, she is fearful of becoming obese and her BMI is low by these signs she may be diagnosed with anorexia nervosa.
