<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>

All living organisms are made of only 20 different aminoacids- this is the correct answer! This means that the genetic code only codes for those 20 aminoacids (for example Glutamine and Lysine).
The 20 aminoacids that can form proteins are also called Proteinogenic amino acids.
Hypertension (high blood pressure) has negative effects on health because people with this condition have a higher risk for heart disease and other medical problems than people with normal blood pressure.
If left untreated , hypertension can lead to :
1. heart attack
2. Stroke
3. enlarged heart
4. Kidney damage.
Once the kidneys are damaged, homeostasis in the body is severely impaired because the body no longer has the ability to clear waste products, which when they accumulate tend to poison the body leading to such conditions as uremia.
