This diagram seems to begin with Multicellularity. So, as you follow the line, the next is tissues, then three-germ layers, bilateral symmetry
So, right before 3 germ layers is tissues
So, the answer is D
Answer:
1. Sarcolemma
2. T-Tubule
3. Sarcoplasmic reticulum
4. Terminal Cisternae
5. Myofibrils
6. Myofilament
7.Thick filament
8. Thin filament
Explanation:
These are all parts of the skeletal muscle and they are all involved in the contraction of your muslces.
The sacrolemma is also known as the myolemma. It is a specialized plasma membrane of the skeletal muscle cell. It is an excitable membrane that shares similarities to the cell membrane of a neuron cell.
The T-tubule extends from the sarcolemma to the sarcoplasmic reticulum (SR). This is the smooth endoplasmic reticulum of the muscle cell. When the sarcolemma gets excited, it triggers the SR to release the calcium ions stored in it. The release of Calcium ions triggers the contraction of myofilaments.
There are two types of myofilaments, the thick myofilament and the thin myofilament. These myofilaments contain contractile proteins, actin and myosin. Thick myofilaments contain myosin where one thick myofilament contains 300 myosin molecules. Thin myofilaments contain contractile and regulatory proteins. These myofilamens make up myofibrils.
Answer:
b. Animals are able to blend into
their surroundings and not be
seen by predators.
Explanation:
When an animal is camouflaged, the animal is not able to be seen by its predator because it looks like its surroundings. Its like playing hide and seek except your playing to survive.
The amplitude measures the amount of displacement in a longitudinal wave.
The answer is C. Cytoplasm.
