b. Gravitational constant
Explanation:
G in the universal gravitation formula represents the gravitation constant. It's value is 2.071×10⁻⁴³ s²⋅m⁻¹⋅kg⁻¹.
- The law of universal gravitation states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them".
Mathematically, the law is expressed as:
F = G
Where F is the gravitational force
G is the gravitational constant
r is the distance
m is the mass 1 and 2 bodies

Answer:
Explanation:
A diploid cell becomes haploid during Meiosis I and is completed after Telephase I. These homologous chromosomes (from mom & dad, all duplicated) pair up during prophase I forming tetrads. The pairs of homologs line up on the metaphase plate during metaphase I
At what stage of meiosis are cells haploid?
Prophase II: Starting cells are the haploid cells made in meiosis I. Chromosomes condense. Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid
Explanation:
Glial cells are the cells present in both the type of nervous system in which they neither conduct electrical impulse nor generate them but they perform some other functions like support.
Astrocytes are one of the type of glial cells which are present in the central system of neurons that is in the spinal cord and the brain.
These astrocytes perform various other functions like
1. Form the blood-brain barrier as they enclose the blood capillaries in the brain preventing leakage.
2. They regulate ionic concentration around the neurons.
3. They can store and produce glucose from the non-carbohydrate source.
4. They control the flow of the blood in the brain
5. They can also play a role in the formation of synapses in the neurons.
