A skeletal muscle<span> fiber is surrounded by a plasma membrane called the sarcolemma, which contains sarcoplasm, the cytoplasm of muscle cells. A muscle fiber is composed of many fibrils, which give the cell its striated appearance.</span>
Answer:
The correct answer will be option-D.
Explanation:
Thylakoid membrane is the membrane of the thylakoid present in the chloroplast which encloses thylakoid lumen.
Thylakoid is the site of the light-dependent reaction as they contain chlorophyll in their photosystem. This membrane carries out main reactions of photosynthesis like water photolysis, ATP synthesis and electron transport chain.
If leaking is observed in this membrane then it will interfere with ATP synthesis as membrane maintains the proton gradient in and out of the thylakoid. The leaking will cause mixing the content of the stroma and lumen which will disturb the proton gradient. This proton gradient will prevent ATP synthesis.
Thus, option-D is the correct answer.
Answer:
It's divided by the portions of the planet that hold life.
- The Lithosphere: The continental land of the planet.
- The Hydrosphere: The aquatic portion of the planet.
- The Atmosphere: The air living creatures breathe.
I'm not too sure which one of these two but its either A or C
The characteristics of the nutria include of those here EXCEPT that "nutria can only live in freshwater marshes in coastal areas along the Gulf Coast".
<u>Option: D</u>
<u>Explanation:</u>
Nutria survives not only in freshwater marshes but also in wetlands, and can respond to various environments reasonably easily. In aquatic habitats, the species flourish and migrate rapidly across rivers into coastal wetlands. Nutria harm prone ecosystems can be seen in many ways.
Beyond destroying plants and crops, nutria kills the channels of ditches, streams, and other water bodies. Even so, the irreversible harm that nutria can do to marshes and other wetlands is of utmost importance. Nutria in these places rely on native plants which hold together wetland soil. This vegetation's degradation exacerbated the depletion of coastal marshes caused by sea level rise.
