How do the laws of evolution explain how convergent evolution occurs?

Answers

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.

Answers

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.

Why can a hurricane cause so much destruction?

Answers

Answer:

When a cyclone continues to be out over the ocean, the winds and huge waves that area unit created by the storm become dangerous for ships and alternative water vessels. ... once the cyclone approaches land it will cause an enormous quantity of injury. Flooding caused by storm surges is one among the foremost dangerous components of a cyclone.

Hurricanes generate strong winds that can completely defoliate forest canopies and cause dramatic structural changes in wooded ecosystems. Animals can either be killed by hurricanes or impacted indirectly through changes in habitat and food availability caused by high winds, storm surge, and intense rainfall.

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.

Answers

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.

A The magnitude of the electrostatic force between the balloons will decrease, and they will attract each other.

B The magnitude of the electrostatic force between the balloons will increase, and they will attract each other.

C The magnitude of the electrostatic force between the balloons will decrease, and they will repel each other.

D The magnitude of the electrostatic force between the balloons will increase, and they will repel each other.

Answers

Answer:

Explanation:

"Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges."

Source:

https://www.britannica.com/science/Coulombs-law

If the student brings two negatively charged balloons closer to each other magnitude of the electrostatic force increases and they will repel each other. The Correct option is D.

What is Electrostatic force?

Electrostatic force is a force of attraction or repulsion between two unlike or like charges respectively. when like charges come closer to each other, they gets repel by one another and it gets attracted for unlike charges. Force of attraction or repulsion between two point charges are given by coulomb's law, which states that " The force of attraction or repulsion between two charges are directly proportional to product of magnitude of two charges and inversely proportional to square of distance between them.

Charged bullions has charges accumulated on the surface. when two negative charged balloons comes closer they gets repelled each other.

Hence option D is correct
