​

Answer 1

1 c. 2 b 3 triose.. 4 b

Answer 2

The answer to the following questions are as follows:

1. Option a - Acidic - Most enzymes work at an optimum pH and can be slightly acidic due to the presence of amino acid group since enzymes are proteins.
2. Option b - Astral rays - During cell division astral rays extend towards the periphery
3. Glyceraldehyde is a triose sugar.
4. Option a - Prophase - 1 - It is the most complicated and longest phase in meiosis and includes 5 stages that are leptotene, zygotene, pachytene, diplotene, and diakinesis.
