Answer:
Skeletal muscle contractions help maintain body temperature. (Ans. E)
Explanation:
Skeletal muscle contributes to maintaining temperature homeostasis in the body by producing heat. Muscle contractions require energy & produce heat as a by-product of metabolism. All types of muscles produce heat, but a large amount of Skeletal muscle found in the body, so it contributes greatly to heat production.
This is noticeable during extreme cold environment shivering produces random skeletal muscle contractions to generate heat to maintain the body temperature.
Skeletal muscle contractions pull (drag) on tendons, which are joined to the bones present in the body. If the contraction of muscles causes the muscle to shorten, the bone (present in the body) & other body part will start to move. Then the energy comes from a skeletal muscle produces heat & maintain the body temperature.
Answer:
amino acids
Explanation:
Proteins are made up of small units called amino acids. The proteins are composed of carbon, hydrogen, oxygen and nitrogen. In addition to nitrogen, proteins may contain phosphorus or sulphur or both. The proteins are referred to as nitrogenous compounds because they contain nitrogen element.
Answer:
Dissimilar organisms might have evolved from a distant, common ancestor.
Explanation:
First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism.
Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.
Therefore they are consider matter. Remember anything with a mass is matter.
