Answer:

Inspiration

Explanation:

Pulmonary ventilation (breathing) can be defined as the flow of air into the lungs during inhalation (i.e., inspiration) and the inverse process where the air out of the lungs during exhalation (i.e., expiration). The lungs are active during the process of inspiration, while they are passive during expiration. Inspiration happens when the intrapulmonary pressure is below the atmospheric pressure, thereby the lungs expand and air enters the lungs.

Equal masses of granite, iron, copper, and lead are placed in sunlight. Based on specific heat, which material will warm up the
levacccp [35]

Answer:

Lead

Explanation:

The material that will warm up the fastest would be<u> lead.</u>

<em>The specific heat capacity of a substance is the amount of heat required to raise the temperature of a unit of the substance by one degree. The higher the specific heat capacity of a substance, the higher the amount of heat required to raise the temperature of the substance and vice versa.</em>

The specific heat capacity (in J/g °C) of granite, iron, copper, and lead are as follows:

Granite - 0.790

Iron    - 0.450

Copper - 0.385

Lead - 0.129

From the table, <u>lead has the lowest specific heat capacity, hence, it will be the fastest to get warmed when equal masses of all the substances are placed in the sunlight.</u>

Cellular respiration in algae, as in all organisms, is the process by which food molecules are metabolized to obtain chemical energy for the cell. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.<span>

Why are negative feedback loops used to control body homeostasis? <br><br> (Short answer)
liberstina [14]

Answer:

Homeostasis is defined as the state of body in which body maintains several chemical and physical changes inside the body affected by external factors.

Negative feedback loop includes a sensor, stimulus, control center, and effector which is used to control homeostasis.

A negative feedback loop is a reaction that reduce an excessive response and maintain the functions within the normal range. for example: if temperature and blood glucose level increases in the body, negative feedback loops control both the variables and maintain homeostasis.  

Hence, negative feedback loops used to control body homeostasis.
