Plasma membrane allows some material to pass through it while on the same time it blocks other material from entering through it.
Answer:
The graphs of all exponential functions have these characteristics. They all contain the point (0, 1), because a0 = 1. The x-axis is always an asymptote. They are decreasing if 0 < a < 1, and increasing if 1 < a
Explanation:
Graphs of Exponential Functions
The graph passes through the point (0,1)
The domain is all real numbers.
The range is y>0.
The graph is increasing.
The graph is asymptotic to the x-axis as x approaches negative infinity.
The graph increases without bound as x approaches positive infinity.
The graph is continuous.
Answer:
They use advance technologies in agriculture.
Explanation:
There is a direct relationship between thriving civilization and it’s agriculture system because they use advance methods and technologies in agriculture instead of traditional practices. They use heavy machinery for tillage in order to save the time, use high yielding varieties, use proper dose of fertilizers, use of pesticides and weedicides in order to protect the crop. They harvest the crop by using thresher in order to avoid post harvest losses. In short, they use all technologies available to make a higher yield in order to earn more profit.
Answer:
Tertiary structure.
Explanation:
The G protein coupled receptor gets activated and deactivated whether they bound to GTP to GDP. This coupling is important for the initiation of signalling cascades in the cells.
The hydrolysis of GTP to GDP is carried out by the enzyme GTPase. This causes the change in the tertiary structure of protein. The different subunits of G protein gets change due to the hydrolysis. This changes the tertiary structure of the protein and any change in the primary structure of protein is not reversible.
Thus, the correct answer is option (b).
