Answer:
Involuntary respiration is controlled by the respiratory centers of the upper brainstem (sometimes termed the lower brain, along with the cerebellum). This region of the brain controls many involuntary and metabolic functions besides the respiratory system, including certain aspects of cardiovascular function and involuntary muscle movements (in the cerebellum).
Explanation:
The respiratory centers contain chemoreceptors that detect pH levels in the blood and send signals to the respiratory centers of the brain to adjust the ventilation rate to change acidity by increasing or decreasing the removal of carbon dioxide (since carbon dioxide is linked to higher levels of hydrogen ions in blood).
The temperature of the earth's surface during different seasons is also affected by
the passage of the sun's rays through the atmosphere.
True
False
Answer:
True
Explanation:
The sun's light rays produce heat which is actually the only reason why we are not living in a block of ice.
Winter is when we are farther from the sun thus it is colder than the summer when we absorb more of the sun's rays.
The statement "the temperature of the earth's surface during different seasons is also affected by the passage of the sun's rays through the atmosphere" is definitely true.
What is an Atmosphere?An atmosphere may be characterized as a type of layer that significantly consists of a mixture of numerous gases that surrounds any celestial body or planet like the earth, mars, etc. The atmosphere of the earth is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
The rays of the sun typically produce a significant amount of heat. Due to this, we are not living in a block of ice and get a source of energy directly from the sun.
During winter, the sun is farther from the surface of the sun, so we receive less amount or indirect light but in summer, we absorb more of the sun's rays. Due to this, the temperature increases and we feel extremely hot outside.
Therefore, the statement "the temperature of the earth's surface during different seasons is also affected by the passage of the sun's rays through the atmosphere" is definitely true.

19. Fresh poultry should be rejected when:
A. It has been shipped in plastic wrap
B. It is slightly sticky to the touch
C. There is no discoloration
D. The receiving temperature is 38°F
Answer:
B
Explanation:
Fresh poultry should be rejected when the receiving temperature is 38°F. Therefore, option (D) is correct.
Poultry must be stored and transported at or below 40°F to guarantee food safety and inhibit the proliferation of harmful bacteria. Exposure to unsafe temperatures during storage or transportation can increase the risk of bacterial contamination and foodborne illness if the receiving temperature exceeds the threshold.
Indicators like plastic wrap during shipment, slight stickiness, or lack of discoloration do not necessarily imply safety concerns or spoilage with fresh poultry, as mentioned in the other options.
