<span>Male adaptations to sperm competition include relatively large testes, large sperm stores and long spermatozoa, mate guarding and frequent pair copulations. Females show no obvious morphological adaptations to sperm competition but, by controlling whether copulations are successful, they probably determine its frequency and extent. Despite this, the evolutionary benefits females acquire from extra-pair fertilizations are poorly understood.</span>
Water is the compound must be present along with urea for the break down of urea.Thus, option B is correct.
<h3>What does urea break down into?</h3>
Urea and water combined together and results into the production of carbon dioxide and ammonia with the help of urease enzyme.
Urea + water = Carbon dioxide+ ammonia
Breakdown of urea occurs in a cycle known as urea cycle and it has five important steps:
- Formation of carbamoyl phosphate
- Synthesis of citrulline
- Cleavage of argininosuccinate
- Glucogenic and ketogenic amino acids
- Oxidation of Carbon skeleton of amino acids
Therefore,water is the compound must be present during the process of break down of urea.Thus, option B is correct.
