Answer;
Acid rain is mostly a problem in the Northern Hemisphere.
Explanation;
This can be attributed to the fact that the area has a large, densely populated cities and a concentrated number of industrial and power plants in an area. These factors contribute to acidic gases in the environment such as sulfur oxide, nitrous oxide, which mix with rain water to form acidic rain. Additionally, prevailing wind direction which brings with it the pollution from the midwest to the north east.
Answer:
1. C
2. B
Explanation:
1. When a plant cell looses some water due to dehydration or being placed in a hypertonic solution, the term used to describe the cell's intial, not severe shrinkage is 'flaccid'.
Here, it's clear that the cell shrank so much that the cell membrane pulled away from the cell wall. The correct term for this severe shrinkage is 'plasmolysed'.
We don't use 'wilted' as a term to describe a cell. We use it to describe the plant as a whole.
2. This is the function of each. Water and ions in xylem and sugars like sucrose in phloem.
Answer:
Option A, B, C
Explanation:
The major advantages of multienzyme complex over a metabolic pathway is that it do not require individual pathway for each enzyme activation or inhibition. Instead it responds efficiently to the equilibrium changes of substrate supply and demand as compared to that of enzymes.
It tightly regulates the processes and is also faster than that of the metabolic pathway.
Hence, option A, B and C are correct
A= U, G= C, T= A You can reverse it as well to find the codons
The Earth's lithosphere is 100km while astehnosphere is 660km so this statement stands true.
Other statements are false like Earth’s mantle is thinner than its oceanic crust as Earth’s mantle is around 3k km while its oceanic crust is just 5km.
Also, Earth’s outer core is thicker than its mantle and Earth’s continental crust is thicker than its lithosphere is false as well.
