Answer:
Haploid
Explanation:
Gametes are mainly produced by the process of meiosis in the gamete mother cells. Meiosis reduces the chromosome number to the half in the gametes and produces haploid gametes. Haploid cells are the ones that have only one complete set of chromosomes. The fusion of haploid male gamete with a haploid female gamete restores the diploid chromosome number in the zygote.
For example, each of the human sperms and egg cells has 23 chromosomes. Somatic cells in humans have 46 chromosomes. The fusion of a sperm carrying 23 chromosomes with an egg having 23 chromosomes restores the 46 chromosomes in the zygote.
Answer:
In this ELISA procedure, a sample of protein is immobilized in the plastic well and then antibody for this protein added and incubated, and cleared out. In the given setting detection, the antibody is conjugated with the protein of interest and if the substrate molecule added to the reaction it will produce a colored product by reacting with the enzyme.
No reaction will take place in the well in case of not adding secondary antibody or detection antibody to the reaction and no colored product will be received.
Answer:
A number of human activities can impact on the water cycle: damming rivers for hydroelectricity, using water for farming, deforestation and the burning of fossil fuels. We are cheating the water cycle system everyday.
Explanation:
Cells die over the course of life as new ones are formed which makes the body able to grow at a natural pace. Rapid cell division causes cancer because it is cells being crowded from too much cell division.
