For the following question, match the key event of meiosis with the stages listed below.
i. prophase i v. prophase ii
ii. metaphase i vi. metaphase ii
iii. anaphase i vii. anaphase ii
iv. telophase i viii. telophase ii
synaptonemal complexes form or are still present.
a)i only
b)i and iv only
c)i, ii, iii, and iv only
d)i and viii only
e)ii and vi only

A)I only

Explanation:

The synaptonemal complex is formed during the prophase 1 of meiosis. The synaptonemal complex is a s a protein structure that is formed between the homologous chromosomes that form a bivalent.  This structure binds and holds homologous chromosomes together and allows crossing over and genetic recombination between them. Crossing over and recombination occur in prophase 1, therefore, the synaptonemal complex disintegrates before the end of prophase 1.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
