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.

Viruses acquire an envelope during the maturation step of a cell's viral infection?
Flura [38]
It depends on which virus you are referring to specifically. Viruses come in many shapes and types; their variations are tremendous.

For HIV and Influenza, viruses acquire their envelops after maturation, during the budding off or detachment stage from the host cell.

Hope this helps! :)

Why can the same trna and rrna molecules be used to synthesize a wide variety of polypeptides
Drupady [299]

Answer: The transcription and translation process allows trna and rrna molecules to be used to synthesize wide variety of polypeptides.

Explanation:

DNA molecule is made up of information for coding proteins. This information is passed on the mRNA during a process known as transcription. Transcription is the first of many steps of DNA based gene expression in which a part of the segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase.

Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During the process of transcription, a DNA sequence is read by an RNA polymerase, which gives a complementary, antiparallel RNA strand referred to as a primary transcript.

A large diversity among genes is followed by a large amount of various mRNA molecules. However, the ribosomes consist of rRNA, which is included in the process of translation. Translation is the process whereby ribosomes in the cytoplasm or ER synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus. The overall process is called gene expression.

The smallest of the three types of RNA is tRNA, which has only 75 to 95 nucleotides and has a role in bringing particular amino acids to the growing polypeptide. It can be concluded that mRNA contribute to the diversity of polypeptide molecules due to the fact that it carries an information about their synthesis.

50 POINTS Explain how predators and prey regulate each other's population growth. Give an example.
salantis [7]

The predators will feed on the prey lowering their birthrates, but while feeding on the prey, the predators' growth rate will lower since there is less prey to feed on.
