Answer:
The correct answer is: lets the air get inside the lungs.
Explanation:
The process of ventilation, or breathing, consists of two parts: <u>inhaling and exhaling.</u>
Inhaling is the name of the process that is responsible for the air entering the body by the respiratory tract. Exhaling is the opposite, it lets the air out. Both are equally important since they allow the gas exchange necessary for the oxygenation of the blood.
When inhaling, the diaphragm and the external intercostal muscles contract. This pulls the ribcage upwards and outwards, which increases lung volume while decreasing the air pressure inside.
1- golgi bodies

i know those ones are right.
3 and 6 are either lysosome and vacuoles but i don’t remember how to tell the difference
Answer:
It is beneficial to study plant and animal compounds for a multitude of reasons such as Sanitation, Bacterial fighting, and many more. An example of a plant compound that has benefited humanity would be penicillin which is derived from plants, it is considered the first true antibiotic.
Explanation:
Before 1928, humanity had conquered most of its enemies and people were only limited in lifespan by internal mechanisms being disrupted or failing, such as cancer, genetic errors,viruses, and BACTERIA. But in 1928 by accident a scientist discovered penicillin and finally deaths by bacteria were dropping to the point where in the past a mere cut could mean death by bacterial infection when compared to the present, humanity now doesn’t even consider bacterial infection, and that is all due to the power of penicillin and other antibiotics.
Water is a polar compound because there is a positive hydrogen end and a negative oxygen end, this is caused by an uneven electron distribution
Answer:
C
Explanation:
The number of ATPs formed in the Krebs Cycle is 34 while in Glycolysis is 4. Adding the two result in 38 ATPs. However, remember that Glycolsysis takes up an initial 2 ATPs before the 4 are produced. The net ATP production in glycolysis is, therefore (4 – 2) = 2 ATPs. The overall net production of ATPs in aerobic cellular respiration is therefore 36 ATPs.
