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.

Human blood types are characterized by the presence absence of surface markers known as a tigers on the surface of red blood cel
zalisa [80]

Answer:

characterized by presence or absence of antigens

the blood types are A, B, O, AB

Explanation:

There are two antigens and two antibodies that are mostly responsible for the ABO types.  The specific combination of these four components determines an individual's type in most cases. Erythrocytes and serum were related to the presence of antigens on these erythrocytes and antibodies in the serum. these antigens  are A and B, and depending upon which antigen the erythrocytes express, blood either belonged to blood group A or blood group B. A third blood group contained erythrocytes that reacted as if they lacked the properties of A and B, and this group was later called "O" blood group. The fourth blood group AB, was added to the ABO blood group system. These erythrocytes expressed both A and B antigens.

Blood group   Antigen present on RBC    Antibodies in serum    Genotype(s)

      A                        antigen A                             anti-B                     AA or AO

      B                        antigen B                             anti-A                     BB or BO

      AB              both A and B antigen                 none                         AB

      O                           none                           anti-A and anti-B           OO

How does the balance of populations in the ecosystem change when the rattlesnake population increases? Choose the two correct an
In-s [12.5K]

Answer: The correct options are C and E.

Explanation: When the rattlesnake population increases, the population of grasshopper and prairie dog are also decreases.

Both grasshopper and prairie dog are herbivores and eaten by rattlesnake. When rattlesnake population increases they feed on grasshopper and prairie dog and decrease occurs in their population.

In humans, a type of blindness is due to a dominant allele; normal vision is the result of a recessive allele. Migraine headache
yan [13]

Answer:

Yes.

Probability of such child = 1/2 or 50%

Explanation:

According to the question, below are the genotypes and phenotypes possibilities:

aa = normal vision & no headache

Aa = normal vision & no headache

AA = blindness & headache

                                                                      Male                       Female

                                                                        Aa                            aa

Possible genotypes of progeny:            Aa        Aa           aa         aa

So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.

Mathematical expression is as under:

2/4 = 1/2 that means 50% progeny.
