Answer:
El complejo sináptonémico se forma en la fase temprana de la profase 1. Asegura la alineación de los cromosomas homólogos, al igual que una cremallera que mantiene los cromosomas homólogos en alineación (sinapsis) y la recombinación de estos cromosomas. Por este complejo asegura una segregación cromosómica precisa, en la metafase 1
The synaptonemic complex is formed at early phase of pro phase 1.It ensures the alignment of homologous chromosomes, just like a zipper which holding homologues chromosomes in alignment(synapsis) and recombination of these chromosomes..Therefore at meta phase I, the accurate paring aided by this complex ensures accurate chromosomes segregation.
Explanation:
The answer is D because the law of matter is to not to change or create
Answer:
active enzyme + substrate→ product + active enzyme
Explanation:
The equation is just a representation of mechanism of enzyme action.
About enzymes, we know that they are proteinaceous substances or chemicals which take part in a chemical reaction and speed up the rate of reaction.
This is because they react with the substrate and transform it into a product in a quicker manner.
Mechanism of action:
- All the enzymatic activities are due to its specific nature and shape. Enzymes have a certain area called active site which is responsible for the enzymatic activity.
- The substrate attaches itself into the active site of the enzyme, enzyme starts its working and the end of reaction is when a product is formed and enzyme in its active form is still available and ready to speed up another reaction.
- You can see mechanism and understand in a better way in attached figure.

The correct answer should be A) Cell theory explains cell behavior where a law would describe it
Theories are used to explain phenomena, while laws just describe what will always happen. Such as the law of thermodynamics that describes what is going on inside a room when heat leaves it.
