Answer:C
Explanation:P shows a increase of kinetic energy and a phase change from solid to liquid
The tropomyosin filament would not be dislodged preventing contraction.
The cross bridges would remain linked and therefore contraction would stop
The cross bridges would break apart due to the presence of calcium ions enabling some contraction
The myosin heads would separate from the actin molecule due to the release of ADP that was previously present.
<span>1.ATP hydrolysis </span>
2.Detachment of myosin head from actin
3.Power stroke
<span>4.Crossbridge formation</span>
Answer:
All of the listed responses are correct.
Explanation:
Ecotourism is the approach to allow humans to visit the natural habitats of flora and fauna without harming these natural resources in one or other ways. Some places/countries are specifically rich in natural habitats of species diversity and endemism. These habitats are mostly being destroyed by human activities.
These natural habitats of high endemism and habitat destruction are called biodiversity hotspots. These regions present in various countries should be protected to slow down the current loss of biodiversity. Non-native species mostly harm the native species. In absence of any competitors or natural predators, these non-native species flourish well in new habitats and deprive the native ones of resources.
Phospholipids : This makes up the bi-layer which is the membrane's basic structure and has great control over what can enter and exit the cell, due to their hydrophobic tails and hydrophilic heads.
Cholesterol : This also controls entry and exit of substances as it also exhibits hydrophilic heads and hydrophobic tails. It also stabilises the membrane and affects its fluidity (the more there is, the more fluid is the membrane.)
Glycolipids : Those can act as receptor molecules (essential for cell-signalling), antigens and in cell-adhesion
Answer:
<u>Option-(B):</u> The protolith is the un-metamorphosed rock.
Explanation:
- <u>Prolith and Slate:</u>
Both are the same thing but the difference in the form, or we can say, that the prolith is the non-metamorphosed form and the slate is metamorphosed form of the same substance. As the slate is the fine grained form of rock and it posses very unique structure, as these rocks are mostly in the construction and designing purpose of beautification of buildings of various types.
