Answer:
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:
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.
What are the benefits of wind power?The majority of wind power or wind energy is generated through the use of wind turbines. Wind power is a popular, long-lasting, and renewable energy source that has less of an environmental impact.
The process by which the wind is used to generate mechanical power or electricity is referred to as wind power or wind energy. The kinetic energy of the wind is converted into mechanical power by wind turbines.
This motion energy, or wind flow, is utilized by humans for numerous purposes: flying a kite, sailing, and even making electricity. The process by which the wind is used to generate energy is both referred to as "wind power" and "wind energy."

Question 4 options:
True or false
The breaststroke is not started in the dive position in the water. Therefore, the statement is false.
What is breaststroke?The breaststroke is not started in the dive position in the water. It started in a stationary position with the swimmer, which faces forward and floats in the water.
The swimmer then takes a breath followed by the beginning of the stroke by pulling both arms back simultaneously and lifting their head and shoulders out of the water.
The legs are brought together by the swimmer andglides forward before the repetition of the arm and leg movements. It is the butterfly stroke because of the dive position, as the swimmer resurfaces both arms extended above the head to begin the stroke.
Therefore, the breaststroke is not started in the dive position in the water as it is started in a stationary position with the swimmer facing forward and floats in the water.

In any population, some individuals will have more kids than other individuals (just by chance). Some of those individuals will be "lucky" and survive. Explain the cartoon and how it shows this idea.
Answer:
By people stepping on the little bugs, it kills them. and when they are born some will die and others won't
Explanation:
The cartoon refers to the principle of natural selection, which operates in many species, including bugs.
When individuals of a species reproduce, their offspring inherit certain traits or characteristics that can be advantageous or disadvantageous. In the case of bugs, some may have stronger exoskeletons, faster reflexes, or better camouflage, which can help them survive being stepped on or avoid being noticed by predators.
As a result, those bugs with advantageous traits are more likely to survive and reproduce, passing on their favourable characteristics to the next generation, while those without these traits are more likely to die. This is an example of natural selction.
