The epidermis and the dermis
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) be able to be disproven
Explanation:
Scientific investigations involve the use of scientific methods, which is a principled guideline for scientific observations. One of the steps of the scientific method includes formulating an hypothesis, which is a predictive statement about the possible solution to an observed problem. This hypothesis is FALSIFIABLE i.e it must via experimentation/testing be proven to be false.
This qualifies a happening or phenomena as SCIENTIFIC. It must be able to be repeatedly tested for the purpose of disproven or falsifying the hypothetical claim.
Answer:
Moderate chemical weathering
Explanation:
moderate chemical weathering will be the type of weathering
Answer:
All of their functions are performed by a single cell.
Explanation:
Unicellular are those organisms whose body is madeup of one cell. In Unicellular organisms one cell perform all the functions and activities of the cell such as respiration, digestion, excretion and reproduction. Unicellular organisms reproduce asexually such as binary fission, budding and fragmentation etc. In Unicellular organisms, a single cell is divided into two equal parts and each part becomes a new organism.
