Answer:
Contraction.
Explanation:
Muscle tissues are defined as they are elastic and extensible in nature. In other words it's also defined as they are able to stretched and returned to its original size and shapes. A unique feature of muscle tissue is they are able of contractile in nature. With the help of this contraction they are able to sliding myosin and actin filaments which are present in muscles tissues.
Basically muscle tissues are three types:
1) Skeletal muscle: They are strong and rapid in contraction.
2) Cardiac muscle: They are strong in contraction.
3) Smooth muscle tissues: They are slow and weak in contraction.
Answer:
A
Explanation:
The dead matter from organisms such as plants and animals that die need to be recycled so the nutrients in the matter are released and used up by other organisms. This is how sustainability is achieved in ecosystems through a cyclical nature of nutrients flow. Decomposition of the dead matter is done by decomposers such as fungi and bacteria. Without them, the dead matter would accumulate while the soil would lack nutrients for plants to grow and for other bacteria to utilize for energy. This would affect the rest of the food chain/web causing the ecosystem to collapse.
Answer:the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
