Can someone please help me with just this one question?
The savanna grasslands of Africa is an example of a biome that supports large populations of grazing herbivores, few birds etc. The savanna supports grazing animals such as wildebeests, antelope, zebra and many other grazing species. There are few species of birds because the landscape there is almost void of trees. Only a few species of acacia dot the extensive grassland.
<h2>Muscular strength</h2>
Explanation:
Muscles that are elongated while activated (i.e., eccentric muscle action) are stronger and require less energy (per unit of force) than muscles that are shortening (i.e., concentric contraction) or that remain at a constant length (i.e., isometric contraction)
stronger muscle contraction includes:
- Potassium accumulate in the sarcoplasm
- Increase in muscle belly circumference
- Increased stimulus frequency
- Increased requirement
- Lesser proportion of motor neurons to muscle fibers
weaker muscle contraction includes:
- Begin contraction with muscle already 50% contracted
- Circular arrangement of muscle fascicles
- Lower sarcoplasm pH
