calcium signaling in individual app/ps1 mouse dentate gyrus astrocytes increases ex vivo with aβ pathology and age without affec
irakobra [83]

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.

Why do malleable and ductile physical properties help make minerals useful? Pls answer with a simple/easy to understand answer
vodomira [7]

Answer:

Malleable and ductile properties indeed help minerals useful. Both properties are useful because they help in transforming the shapes of minerals. Malleability is a useful property since it can be flattened or pounded by a hammer. Also, the ductile property makes it possible for the minerals to be stretched in the form of a wire. These two properties makes it useful for minerals.

Explanation:

Malleable and ductile properties indeed help minerals useful.

Both properties help in transforming the shapes of minerals.

Malleability is a useful property since it can be flattened or pounded by a hammer.

The ductile property makes it possible for the minerals to be stretched in the form of a wire.

In your own words, explain why photosynthetic cyanobacteria were likely the first organisms to survive and thrive in the harsh c
mylen [45]

Explanation:

cyanobacteria are aquatic and photosynthetic, that Is they live in the water, and can manufacture their own food.Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see.they have the distinction of being the oldest known fossils more than 3.5billion years old, in fact! it may surprise you then to known that the cyanobacteria are still around,they are one of the largest and most important group of bacteria on
