Answer:
Fraternal twins
Explanation:
Hyperovulation is when a mother drops two or more eggs during a single cycle. Each egg acts individually and can be fertilized by a sperm. If egg A is fertilized by a sperm with Y chromosome and egg B is fertilized by a sperm with an X chromosome. Egg A will be a male child, while egg B will be a female child

One of the most commonly repeated criticisms of wind power is that it kills birds. The giant spinning turbines are basically bird death traps—and often they cut through prime flying space, making the carnage even worse. At least that's the story. But how many birds really do die?
If you look around for statistics about bird deaths from wind turbines get you wildly different numbers. Some say just 10,000 birds a year
Explanation:
Answer:
The correct choice is ''ion electrochemical gradients''.
Diffusion of ions across membranes through specific ion channels is driven by <u>ion electrochemical gradients</u>.
Explanation:
An electrochemical gradient can be considered as that electrical (electrostatic pressure) and chemical (diffusion) force that determine the movement of molecules and ions across the membrane. This electrochemical gradient, in addition to causing movement of substances through cell membranes, is also a type of potential energy available for the performance of different cellular activities, potential energy called membrane potential.
