Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How
did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn't occur?
Hello. You have not shown the model of meiosis to which the question refers, which makes it impossible for this question to be answered accurately. However, I will try to help you in the best possible way.
Crossing over is a genetic phenomenon that occurs when two sister chromatids are broken at some points and the pieces are exchanged between them. these exchanges cause the appearance of completely new gene sequences, which can completely affect the expression of stretches in the cells where the crossing over happened, since this cell will have a different gene sequence than the others.
As you may already know, chromosomes are formed by two filaments, called a chromatid. These filaments are united by the centromeros and the union of two filaments and a centromero is called sister chromatides.
<span>well photosynthesis uses sunlight to split H2O and pass on an electron pair to plastoquinone (photosynthesis II) and to NADP+ -> NADPH (photosynthesis I). Also phosphorylation of ADP to ATP..
idk what they mean by recycling.. it would be H2O and CO2 that they "recycle" if anything. </span>
Children who are assertive and good at regulating emotions are more likely to help,share and give comfort to others in distress. If a peer is in distress they will react by frowning,lip biting, comfort seeking,rise in heart rate, and a sharp increase in EEG brain-wave activity in the right cerebral hemisphere that contains negative emotions.
Otros efectos perjudiciales incluyen enfermedades como la fiebre tifoidea y el cólera, la eutrofización y la destrucción de ecosistemas que afectan negativamente a la cadena alimentaria. El agotamiento de los recursos es otro impacto negativo de la tecnología en el medio ambiente. Se refiere al consumo de un recurso más rápido de lo que se puede reponer.
11. The Wood frog starts before the leopard frog so this means that they do not interact except in the end and beginning of wood frog and leopard frog.
