Answer:
Option C
Explanation:
Gastrocnemius and soleus muscles are jointly known as calf. Gastrocnemius is the larger muscle and connects to the knee joint while soleus is smaller muscle that connects to the portion of leg just below the knee. When gastrocnemius is stretched, the knee remains straight while when the soleus is stretched the knee bends.

A biotic factor is a living organism that shapes its environment. In a freshwater ecosystem, examples might include aquatic plants, fish, amphibians, and algae. Biotic and abiotic factors work together to create a unique ecosystem.
Answer:
Euhaline ⇒ Polyhaline ⇒ Mesohaline ⇒ Oligohaline
Explanation:
Let's first define each of these levels:
- Polyhaline: a category of salinity that has medium-high levels of salt
- Mesohaline: a category of salinity that has medium levels of salt
- Oligohaline: a category of salinity that has low levels of salt
- Euthaline: a category of salinity that has high levels of salt
Now, we can order these in decreasing order of salinity:
Euhaline ⇒ Polyhaline ⇒ Mesohaline ⇒ Oligohaline
