COMPLETE QUESTION:
Why might better-insulated buildings make air pollution more of a problem?
ANSWER: It prevents the passage of waste gases out of the building and inflow of fresh air which can leads to health related issues.
EXPLANATION:
Building insulation reduces the heat surplus in warmer weather condition and reduces the heat loss during cold weather condition.
The negativity that comes with insulating a building is an increased air pollution. In the process of preventing heat loss to the environment by insulating a building, there's a resultant reduction or sometimes blocking of air flow inside the building. This will cause the concentration of waste that are in gas form inside the building, emanated from human activities like cooking (fuel burning), respiration, and other activities.
Overtime, this trapped in of waste gases can leads to sick building syndrome (an health related issue).
Answer: b and c
Explanation:
B. Can vary force of contraction.
C. By varying calcium entering the cell.
Answer:
The correct answer is d. plasma membrane
Explanation:
Bacteria do not have membrane-enclosed organelle like mitochondria to generate ATP but even then it produces ATP because in bacterial plasma membrane acts as the machinery of ATP synthesis.
The ATP synthesis in bacteria is the same as eukaryotes. In prokaryotes, the plasma membrane consists of an electron transport system and NADH helps in building the proton gradient across the plasma membrane.
Then after the proton gradient is built in the plasma membrane the proton tends to come back into the cytoplasm through the ATP synthase complex which generates ATP from ADP and inorganic phosphate.
Therefore the correct answer is d. plasma membrane.
The part of a cell that gives the cell unique characteristics is the Nucleus
Answer: Option A."Hydrolysis"
Explanation:
Polymers breaks down into monomers following hydrolysis reaction.
hydrolysis is a chemical reaction that occurs when a water molecule inserts across the bond.
In hydrolysis reactions, the polymer breaks or divide into two components one part that gains hydroxyl molecule (OH–) and the other part that gains gains a hydrogen atom (H+) due to split of water molecule.
Hence, the correct option is A.
