Answer:
Scientists did not know how traits were inherited
Explanation:
Scientist before did not know how the trait is passed on not until Griffith's experiment.
To answer this we need to analyze each statement
camouflage, mimicry, and stingers: This is meant to escape predation and fend off predators, so this is the correct answer.
hibernation and migration: This is meant for breeding and or food energy storage, to pass hard seasons so is also incorrect.
courtship and breeding behaviors: This is meant for reproduction and to ensure offspring so this is incorrect.
nesting and food gathering: this is a behavior for survival, resource use rather than defense, si this is not correct.
Look at this for ur answer
Answer:
Seminal vesicle
Explanation:
Seminal vesicle secretes an alkaline and viscous fluid that constitutes about 60% of the volume of semen. The fluid secreted by seminal vesicle contains fructose which is a monosaccharide sugar, prostaglandins, and clotting proteins. The alkaline nature of the seminal fluid neutralizes the acidic environment of the male urethra and the female reproductive tract. This is required as the acidic conditions inactivate and kill sperm.
The fructose sugar serves a fuel for ATP production by sperm. Prostaglandins are responsible for sperm motility and viability as they stimulate smooth muscle contractions within the female reproductive tract. Therefore, a malfunctioning seminal vesicle would result in low semen volume and reduced motility due to the scarcity of energy.
