How does convergent evolution happen?
Convergent evolution is similar to parallel evolution, which occurs when two independent species evolve in the same direction and thus independently acquire similar characteristics; for instance, gliding frogs have evolved in parallel from multiple types of tree frog.
Convergent evolution is when different organisms independently evolve similar traits. For example, sharks and dolphins look relatively similar despite being entirely unrelated. ... Another lineage stayed put in the ocean, undergoing tweaks to become the modern shark.

Which of the following does not describe an ecosystem in a state of dynamic equilibrium?
A An ecosystem that is constantly changing
B An equilibrium that becomes unbalanced.
C An ecosystem that can return to a balanced state.
D An ecosystem that can respond to disruptions.
An ecosystem that is constantly changing is not in a state of dynamic equilibrium.
A state of dynamic equilibrium is a state in which an ecosystem is relatively balanced. The ecosystem may be com unbalanced by by natural changes but returns to its original state. An ecosystem in a state of dynamic equilibrium remains unchanged for a long time.
Hence, an ecosystem that is consistently changing is not in a state of dynamic equilibrium because dynamic equilibrium has to do with relative stability of an ecosystem.

Explanation:
A student rubs a rubber rod with fur, producing a negative charge on the rod. The student then touches the rod to a hollow, neutral metal sphere that stands on an insulating plastic stand. This transfers negative charges from the rod to the sphere: Which statement best predicts what will happen to the charge, and why?
A It will distribute itself evenly over the surface of the sphere, because like charges repel and the sphere is a conductor.
B It will remain at the point of contact between the rod and the sphere, because resistance in the metal prevents the charges from easily moving.
C It will slowly drift to the bottom of the sphere, because the charges rapidly attach to individual atoms, making them slightly heavier than surrounding atoms.
D It will quickly spread to the air around the sphere, because it will seek to occupy as large a volume of neutral matter as possible.
Answer:
B It will remain at the point of contact between the rod and the sphere, because resistance in the metal prevents the charges from easily moving.
Explanation:
The rubber rod will distribute itself evenly over the surface of the sphere, because like charges repel and the sphere is a conductor. So, the correct option is A.
What is Conductor?A conductor is defined as an object or type of material that allows the flow of charge in one or more directions where materials made of metals are common electrical conductors. The property of conductors that allows them to conduct electricity is called conductivity while the flow of electrons in a conductor is called electric current.
In the given example, the rubber rod will distribute itself evenly over the surface of the sphere, because like charges repel and the sphere is a conductor. Some common conductors examples are copper, aluminum, gold, and silver.
Therefore, the correct option is A.

List and describe each these basketball terms:
“Jump Ball”
“Assist”
“Steal”
“Lay Up”

Answer:
Jump Ball; used to start the game. The referee throws the ball up in the air, above two members of opposite teams, who have to jump up to try and tap the ball towards one of their teammates.
Assist: a pass made from one player to another, that directly leads to making a basket. For a pass to count as an assist, the ball has to be passed directly to the played who scores, and points must be earned.
Steal: when a defensive player intercepts the ball from an offensive player.
Lay Up: a shot made from below, by running up to the basket from the side, jumping, and bouncing the ball off of the backboard, into the basket.
Technical Foul: a foul given for "unsportsmanlike behaviour", such as making fun of an opponent.
Answer:
Assist: A pass to a teammate that results in a made basket.
Steal: To take the ball away from an opponent.
Jump Ball: a method of putting a basketball into play by tossing it into the air between two opponents who jump up and attempt to tap the ball to a teammate

Answer:
There is a thing called a continental drift. It started about 200 million years ago. At first the continents were all attached, this super continent was called pangaea. Continental drift occurs because of the shift of the tectonic plates within the earth's outer shell. The heat from within the earth triggers movement to occur. This a very slow process though. It took 200 million years for the continents to get where the are now and would probably take another 200 to collide.
