Answer:
The answer that are true are:
1) A: Horses and Mules can be bred but their offspring is typically sterile. This could be an example of hybrid breakdown.
2) C: One species of sea turtle mates during the early spring and a closely related species mates during late spring. This is an example of temporal isolation.
3) D: One species of sea urchins can not fertilize another closely related species because the eggs do not have a receptor for the sperm. This is a good example of gametic isolation.
4) E: Damselflies have sensory receptors that are sensitive to touch (tactile cues). Two related species of damselflies are unable to mate because their touch cues are not compatible. This is a good example of mechanical isolation.
<span>During digestion, the blood picks up nutrients absorbed through the gi tract and transports them to the <u>different organ systems of the body.</u> The oxygen and nutrient-rich blood can be transported throughout the body by the different blood vessels that surround it. Without blood circulating through the body, it would be hard for the body to maintain its homeostasis and survive for long.</span>
Answer:
Angle between the forces 
degrees
Explanation:
The resultant force value 
times of Force F
Where R is the resultant force
Cos X is the angle between the two forces.
On further simplifying the equation we get
degrees
Angle between the forces degrees
I think 1 and 3 but don’t count me
