<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>
Answer/Explanation:
Blue eyes have less melanin than brown eyes. Melanin helps vision and hearing. It also affects behaviors and balance.
This means Brown eyes are healthier than blue eyes.
Studies have shown even for cats that if they have white fur and blue eyes(lack of melanin) that they would have a 90% chance of being born deaf.
Answer:
Aerobic activity
Explanation:
Aerobic activity can be defined as a type of physical activity which involves the the circulation of oxgen through the blood.
Aerobic activity is an activity which increases the amount of blood that goes to the muscles. Oxygen is needed for the proper functioning of the muscles.
When carrying out any type of physical activity such as weight lifting the muscles need a large amount of oxygen to function well. The oxygen in the body is used to break down glucose and create the fuel which is needed by the muscles in the form of ATP. Different aerobic activities carried out also helps to strenthen the lungs.
The answer is c because they are not identical to parents but have some things in common ( resemble)
The Sun's outer gases extend far beyond the photosphere (Figure 6). Because they are transparent to most visible radiation and emit only a small amount of light, these outer layers are difficult to observe. The region of the Sun's atmosphere that lies immediately above the photosphere is called the chromosphere.
