Your body is composed of three types of muscle: skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle makes up 40 percent of your total body weight, and smooth muscle and cardiac muscle each make up 5 percent of total body weight. Your muscles must contract in order to facilitate vital bodily functions. Skeletal and smooth muscles are located in different areas in your body to serve their distinct purposes.

Why was miasma theory replaced?
vredina [299]

Answer:

Miasma theory was replaced because John Snow collected data that showed that germs cause disease.

Explanation:

The theory of miasma was proposed in the past when some scientists —like doctors Thomas Sydenham and Giovanni Maria Lancisi— thought that disease was the product of emanations originated by the decomposition of organic matter. This theory was based on the fact that diseases predominated in places with poor hygienic conditions.

John Snow, an english physician, was one of the main contributors to the <u>microbial theory of disease</u>. In 1854, while a cholera epidemic was occurring, he collected data and organized it statistically and then concluded that the disease was caused by germs present in drinking water. This <u>data was contrary to the miasma theory, which would eventually be displaced by the microbial theory of the disease</u>.

Why do different individuals of the same species have different traits?
deff fn [24]

Individuals of the same species have different traits because they have different genes which code for different proteins. B would be the correct option.

<h3>Variations</h3>

Organisms of the same species can have different traits due to a difference in their proteins.

Genes are responsible for proteins and proteins are an expression of traits. Thus, with different proteins come different traits.

Hence, once there is a difference in the DNA sequence of organisms, different proteins will be produced, and different traits will be expressed.
