Explain how parasitism differs from commensalism.

Answers

Answer 1

Answer: Commensalism is an interaction in which one of those species would benefit, and the other one would not be affected. Parasitism is an interaction in which one of those species would benefit at the expense of the host organism. Thus, in commensalism we have one positive and one neutral result while in parasitism we have one positive and one negative result.

What are Mammals?

Mammals are a group of vertebrates in which the young are nourished by the milk of the special mammary glands of the mother. Mammals are distinguished by many other unique features such as hair being a typical mammalian feature but in some mammals such as whales, it has disappeared except in the embryonic stage.

The lower jaw of mammals is attached directly to the skull, rather than to a separate bone called the quadrilateral, as in all other vertebrates. A series of three small bones conduct sound waves to the middle ear while the muscular diaphragm separates the heart and lungs from the abdominal cavity.

Mature red blood cells (erythrocytes) in all mammals lack a nucleus, while all other vertebrates have red blood cells. All of them require care from parents after birth.

Thus, Mouse needs care from its parents after birth. So, the correct option is (C).

Which best describes an axon with myelin and an axon without myelin?Impulse transmission would be faster in the axon with myelin.

Impulse transmission would be slower in the axon with myelin.

An "all" response would occur in the axon with myelin.

A "no" response would occur in the axon with myelin.

Answers

Impulse transmission would be faster in the axon with myelin.

What is Myelin?

A protective layer or sheath called myelin develops around nerves, including those in the brain and spinal cord. It is composed of fatty and protein components.

Electrical impulses may move swiftly and effectively along nerve cells thanks to the myelin coating. These impulses decelerate down if myelin is compromised. Multiple sclerosis and other disorders may result from this.

Each nerve cell has a myelin sheath, which is a type of sheath (neurons). The primary "body" or axon of a neuron is covered in a protective covering made of protein and fat (lipids).

Therefore, Impulse transmission would be faster in the axon with myelin.
