Answer:
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.
Following are the choices:
a. nonrenewable energy sources b. renewable energy sources
c. carbon sequestration d. recycled plastics
The correct answer is:
b. renewable energy sources
Explanation:
Renewable energy is energy that is obtained from renewable resources, which are naturally provided on a human timescale, such as sunlight, wind, rain, tides, waves, and geothermal heat. Renewable energy compares to the provision of energy via renewable sources which are simply replaced fast enough as being used.
The nuclear membrane reforms; the chromosomes align in the middle of the cell.
The chromosomes replicate; the nuclear membrane dissolves.
The sister chromatids are separated; the chromosomes condense.
Which of the choices below describe one similarity between meiosis II and mitosis?
In both processes, sister chromatids are pulled apart.
Homologous chromosomes separate in both stages.
b.homo habilis
c.australopithecines
d.homo erectus
Answer:
pfu/ml
Explanation:
Given -
Bacteriophage dilution ml
Volume of bacteria and plate with top agar ml
Number of plaques pfu
Dilution (d)
Final concentration of phage stock is equal to
Where pfu is the count of plaques
d is the dilution and v is the volume
Substituting the given values, we get -
pfu/ml
