In "The Tell-Tale Heart," what prevents the narrator from killing the old man during one of the first seven nights? The narrator says that his reason for killing the old man is that he does not like the old man's "pale blue eye, with a film over it" - he calls it a "vulture eye" and an "Evil Eye".
The energy released is used for assembly of actin filament with myosin head. when myosin is attached to ATP its heads cannot bind to actin and therefore muscle will remain in relaxed form. However during muscle contraction an enzyme referred to as ATPase hydrolyses ATP to ADP and organic phosphate in the process releasing energy. The energy released changes the position of head of myosin which facilatate its binding with actin. Myosin moves towards m-line dragging actin along with it reducing the length of sarcomere leading to muscle contraction.
Answer:
It fuses with and becomes part of the plasma membrane.
Explanation:
Exocytosis -
Exocytosis is the process of expelling out the substances from the cell . It also helps in the cell transport and cell signalling process .
In this process a large amount of molecule are released and making it a form of the bulk transport .
In this process , the secretory vesicles are then carried to membrane of the cell and then their contents are secreted into the extracellular environment .
Answer:
The tree will not survive due to the nature of the tundra
Explanation:
The tundra comes from a finnish word "tunturia" which means barren or treeless land. It is classified as a cold icy desert with permafrost on the ground. Unlike the tropical rain forest which is a wet climate group and is a forest of tall trees in a region of year round warmth, the tundra is cold and dry. The tundra soils are formed at high altitudes, they are usually frozen. Common plants in tundra are shrubs, herbs, lichens and grass and usually grow in groups and remain closer to the ground for prevention against cold winds. The cold nature of the tundra and its soil prevent the growth of trees because trees need to have deeper roots and they cannot grow on frozen ground.
