I believe the answer is b.
Answer:
True
Explanation:
Because within the prokaryotic domain, there are five main groups of bacteria that perform tetrapyrrole-based photosynthesis. They are proteobacteria (also known as purple bacteria), heliobacteria, Chloroflexi (filamentous bacteria also known as green non-sulfur bacteria), Chlorobi (green sulfur bacteria), and cyanobacteria.
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.
plants make food by mixing water with energy from the sunlight in its leaves along with carbon dioxide to produce food and oxygen. I personally think its amazing.
I believe it is D) initial decay<span />
