<span>Demoralisation is defined as the act of reducing another's confidence and hope, or discouraging and disheartening someone's optimism. This will cause the individual/s to lose faith in the future. The next question then is how does one aid in fighting demoralisation. One is to avoid focusing on the negative stuff. Another is, one could also keep a journal of self-talk. Self-talking is also important because as a human being it is but normal to constantly talk to yourself or you have that inner monologue with yourself. It is that internal dialogue with yourself which can greatly affect your self-esteem as well as your confidence. When one is positively talking to oneself, one can also positively see good things in his or her life and about himself/herself. This is that voice within oneself that makes you look at the bright side of things. When one does these, demoralisation will surely be out of the topic.</span>

Explanation:
Following is a summary of the events of meiosis:
Interphase:
Prepares the cell for division. Duplication of DNA, duplication of centrioles occurs and the cell grows in size. At this stage the cell is diploid (2n).
Prophase 1:
First stage of Meiosis 1.The centrioles move to the poles of the cell, the nuclear membrane disintegrates, homologous chromosomes pair up (in the form of tetrad), form a chiasmata and then exchange segments of chromosomes with each other. This process is called crossing over.
Metaphase 1:
Involves the arrangement of the crossed over, homologous chromosomes on the metaphase plate which is sort of like a web of spindle fibers that originates from the centrioles.
Anaphase 1:
The tetrads arranged on the metaphase plate are pulled apart by the spindle fibers. This is the result of tension that build up in the spindle fibers as they grow towards opposite poles.
Telophase 1:
The last stage of meiosis 1. Involves the arrival of the chromosomes at the poles, the nuclear membrane starts to form and the chromosomes start decondensing. Telophase 1 yields 2 daughter cells with half the number of chromosomes as that in the parent cell.
Meiosis 2:
Meiosis 2 is exactly similar to mitosis. The only difference is that the haploid cells entering meiosis 2 do not duplicate their DNA. Meiosis 2 just involves the separation of the sister chromatids of homologous chromosomes.
- As mentioned above, interphase does not occur before meiosis 2.
- Prophase 2 involves the disintegration of nuclear envelope, centrosomes start moving to the poles.
- Metaphase 2 arranges the chromosomes on metaphase plate.
- Anaphase 2 separates the sister chromatids from the chromosomes.
- Telophase 2 develops the nuclear envelope and separates the nuclei of the daughter cells into 2. Nuclear division id followed by cytokinesis (division of cytoplasm). Telophase 2 result sin 4 haploid daughter cells with one chromatid from each chromosome.
Answer:
The cytolysis of red blood cells is specifically called: hemolysis.
Explanation:
T t
T TT Tt
t Tt tt
Based on the Punnet Square, there would be a 25% chance of having a tt offspring.
Hope this helps!
