Answer:
2.447 × 10⁴ years
Explanation:
Step 1: Given data
- Half-life of the radioactive atom (t1/2): 3,500 years
- Parent-daughter ratio ([A]/[A]₀): 1:127 (1/127)
Step 2: Calculate the rate constant
Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.
k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹
Step 3: Calculate the time elapsed (t)
For first-order kinetics, we will use the following expression.
ln ([A]/[A]₀) = -k × t
t = ln ([A]/[A]₀)/ (-k)
t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y
Answer:
It will shrink because it was placed in a hyper tonic solution
Explanation: Hyper tonic = More solute (sugar)
Hypo tonic = more liquid (water)
When a cell is placed in a solution it will essentially try to balance out so in this case water goes out the cell and solute goes, in shrinking the cell.
Answer:
Thumb print pattern
Explanation:
It is such a big and wide spaced pattern you would almost be certain of a thumb print pattern
Explanation:
Meiosis is a type of cell division in which the ploidy of the organism reduces to half in the daughter cells.
Meiosis produces 4 daughter cells from 1 parent cell with a different combination of the genetic material but haploid chromosomes.
The meiosis process takes place in two stages in which during the first stage, the homologous chromosomes separate reducing the chromosome number to half that is from diploid chromosomes of parents to haploid in daughter.
Since the process of meiosis form haploid gametes in both male and female therefore after fertilization restores the diploid chromosomes of the parent cell and form a diploid structure.
