Step 1-
Your diaphragm moves down as it contracts. Your ribs move outward. These movements make the space inside the chest larger.
Step 2-
Air rushes in through the nose and mouth and passes through the throat. Air then moves past the epiglottis which is open into the trachea.
Step 3
Air moves into your bronchi. The bronchi branch out and end in tiny air sacs, called alveoli.
Step 4
<span>Air moves into your alveoli. Oxygen moves through the walls of alveoli and capillaries, entering the blood.</span>
Step 5
Carbon dioxide moves from the blood through the walls of capillaries and alveoli in order to be expelled by the lungs.
Step 6
Your diaphragm moves up as it relaxes. Your ribs move inward. These movements make the space inside the chest smaller.
Step 7
<span>Your lungs are squeezed and air is pushed out of the alveoli. The air travels back through your bronchi, trachea, and nose and mouth.</span>
Answer;
-Golgi apparatus
Explanation;
-Golgi apparatus is an organelle present in most eukaryotic cells. It is made up of membrane-bound sacs, and is also called a Golgi body, Golgi complex, or dictyosome.
It plays a major function in the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes. The sacs or folds of the Golgi apparatus are called cisternae.
Answer: 20%
Explanation:
I haven't learned this exactly yet, but if there is 30% of thymine, then there has to be 30% of adenine because they match. That would leave 40% for other Guanine and Cytosine, and since they also match that means that it is exactly half, meaning that there is 20% Guanine and 20% Cytosine.
Answer:
Hope this helps:
The carbon (iv) oxide which has been produced by the respiring muscle tissue is diffused into the bloodstream in the form of bicarbonates, a process facilitated by an enzyme called carbonic anhydrase. The carbon (iv) oxide is then carried to the lungs.
