Answer:
Homologous chromosomes are separated from each other.
Explanation:
In meiosis I during metaphase, all the homologous chromosomes of the cell pair up and get arranged near equatorial plate. Subsequently after completion of meiosis I, these homologous chromosomes get separated from each other so that out of the two cells which are produced after meiosis I could get one chromosome each from the homologous pair. During anaphase I of meiosis I, spindle fibres are formed which drag each of these homologous chromosomes towards two opposite poles. Soon after that, cytokinesis occurs during telophase I of meiosis I leading to the generation of two cells.
For example, humans have 46 chromosomes or 23 pairs of homologous chromosomes. After completion of meiosis I, two cells are produced and each one of them has 23 chromosomes.

<h2>
Answer:</h2>
<u>A) Break down of lactose</u> and production of glucose.
<h2>
Explanation:</h2>
Β-galactosidase is a glycoside hydrolases and breaks the lactose polysaccharide into two different monosaccharide called galactose and glucose. It is significant for life forms as it is a key supplier in the generation of vitality and a wellspring of carbons through the separate of lactose to galactose and glucose.
It is additionally significant for the lactose bigoted network as it is liable for making sans lactose milk and other dairy items.
The function of beta-galactosidase is shown in the image below.
