The right answer is 2 divisions.
Meiosis follows the replication of DNA from a reproductive cell (male or female). It allows the passage of a so-called diploid mother cell to 2n chromosome homologous chromosomes to 4 single-chromosome haploid daughter cells. For that it must pass by two successive divisions, the first division is reductionelle generating two diploid cells with n chromosomes. the second division is equational giving 4 haploid cells to n chromosomes from the two preceding cells.
Answer:
The cell wall gives the plant stability
Explanation:
C. a Y chromosome from his father
This is because boys have one X and one Y chromosome, while girls have 2 X's, so the Y must come from the father.
Hope this helps :D
Answer: Its just called a twisted ladder. If you could give me the options i can answer!!
Explanation:
Answer:
Hemoglobin rainier differ from normal hemoglobin with respect to oxygen affinity.
Explanation:
Hemoglobin is one of the most significant protein of Red Blood Cell containing heme(that contain Fe2+ which is coordinated with four porphyrine rings) and globin protein.
Hemoglobin exist in two state one is tensed state or deoxy hemoglobin that have less affinity for oxygen, the other state is relaxed state or oxy hemoglobin that has high affinity for oxygen.
In hemoglobin rainer the formation of new di sulfide bond prevent the formation of ion pairs that normally stabilize the T state as a result T state get unstable and this unstable T state is converted to R state to achieve the stability of hemoglobin structure.
The R or relaxed state of hemoglobin has high oxygen affinity for oxygen.
