Answer:
Eukaryotic cells arose through endosymbiotic events that gave rise to the energy-producing organelles within the eukaryotic cells such as mitochondria and chloroplasts. ... The endosymbiotic theory proposes that one organism engulfed another, and the two co-evolved together until they could not exist independently.
Explanation:
Astrocytes are a group of cells with functional characteristics and distinctive morphological that vary within specific areas of the brain.
For healthy brain function, astrocytes are essential. those become reactive in the case of Alzheimer's disease, which impacts the signaling properties. while experimenting, there was the measurement for instinctive calcium transients ex vivo in hippocampal astrocytes in brain slices containing the dentate gyrus of 9-month-old and 6-month-old APPswe/PSEN1dE9 mice. when they investigated the duration of calcium transients and frequency concerning amyloid-β (Aβ) pathology, the proximity of the astrocyte to Aβ plaques, and aging. there was no change in spontaneous calcium-transient properties of 6M APP/PS1 astrocytes compared to wild-type astrocytes, whereas there was hyperactivity in 9M APP/PS1 astrocytes compared to wild -type, which were longer in duration, also there was an effect of aging too, there was an increase in calcium in the 9-month astrocytes than to the 6-month astrocytes, also there was an increase in the calcium waves in the 9-month astrocytes because of the increase network activity. The findings were that the change in calcium signaling in individual astrocytes of APP/PS1 mice is because of both pathology and aging but these don't have any impact on changes in the astrocyte network activity, which leads to helping to understand changes in neuronal physiology.

The <u>residual air</u> is the amount of air remaining in the lungs after a forced expiration. The volume of air exchanged during normal breathing is called the <u>tidal volume</u>. After a normal inspiration, the amount of air that can then be inspired forcefully is called the <u>inspiratory reserve volume</u>. The total lung capacity minus the residual volume equals the <u>vital capacity</u>. The vital capacity minus the <u>expiratory reserve volume </u>equals the inspiratory capacity. The effects of <u>obstructive disorders</u>, such as asthma or emphysema, may be determined by measuring rapid exhalation with a spirometer.
The lungs are the main organs of the respiratory system. These lungs are also the site of exchange of gases. The air is inspired through the nostrils and this air then reaches the lungs, where the oxygen from air is trapped in the alveoli. This oxygen then diffuses into the bloodstream through capillaries, which is then sent to the heart. From the heart this oxygenated blood travels to different parts of the body. There are several different units of measurement that are used for the measurement of inspired and expired air and their volume.
