Answer:
The thumb bone is part of the appendicular skeleton, while the sternum is part of the axial skeleton. Therefore, the correct answer to the above question is option b.
Explanation:
The human body is considered to have 206 types of bones. The skeleton system is considered to be the basic structure of the body. The whole skeleton system is comprised of bones. The whole skeleton system is divided into two reason which are appendicular skeleton and axial skeleton.
Axial skeleton consists of bones which are axial in nature and helps the human body to stand firm and straight on the ground. The “appendicular skeleton” consists of bones which are other than axial bones like hands, fingers, feet etc.

Answer:
Electron Transport Chain
In the third stage, electrons from the NADH and FADH2 molecules move to the electron transport chain (ETC). These electrons generate the required power to move protons through the mitochondria into the space between membranes. In the final stage of cellular respiration, oxygen combines with the electrons and protons to form water.
<h2>Membrane potential </h2>
Explanation:
- Membrane potential represents charge difference across the membrane, all biological cells are negative inside (cytoplasm) and positive outside (due to difference in ionic distribution)
- In a typical neuron cell membrane potential of cytoplasm is negative at rest (when no stimulus is applied) hence called resting membrane potential
- Resting membrane potential of excitable cells is established by Na+ and K+pump
- Repolarization starts with the efflux of K+ by the opening of voltage gated K+ channels
- Voltage gated K+ channels starts to open when voltage gated Na+ channels becomes inactive
- Hyperpolarization occurs due to excessive efflux of K+ by voltage gated K+ channels
- Additional efflux of K+ occurs due to slow inactivation of voltage gated K+ channels
Answer:
Limpets
Explanation:
Since the arrows represent flow of energy, and there is no path of energy from fish to limpets, limpets won't be affected at all.
