Answer:
The correct answer will be option E.
Explanation:
The non-cyclic pathway or electron transport chain is the pathway which takes place in the light reaction.
The non-cyclic pathway starts from the PSII or P680 when the sunlight excites the electrons form the from the photosystem. This high energy electron is transferred to the higher energy level and loses its energy on the path.
The lost energy is used to form the ATP and NADPH which are used later in the formation of glucose during the dark reaction.
Thus, option E is the correct answer.
In the noncyclic electron pathway of photosynthesis, electrons are not boosted to a higher energy level in Photosystem I.
The statement that is NOT true about the noncyclic electron pathway is (A) Electrons are boosted to higher energy level in Photosystem I.
The noncyclic electron pathway is an important part of the light-dependent reactions of photosynthesis. In this pathway, electrons from photosystem II are excited by sunlight and transferred to photosystem I, where they are further excited to a higher energy level. This pathway ultimately produces ATP and NADPH, which are then used in the light-independent reactions to produce carbohydrates through carbon dioxide fixation.

Greenhousegases are added to the atmosphere through forestfires. The correct option is A.
Greenhousegases are gases the gases which basically trap heat in the earth's atmosphere. The sun shines through the atmosphere during the day, warming the earth's surface.
The earth's surface cools at night, releasing heat back into the atmosphere. However, some of the heat is trapped in the atmosphere by greenhouse gases.
Greenhousegas emissions have far-reaching environmental and health consequences. They contribute to respiratorydisease due to smog and air pollution, and they cause climate change by trappingheat.
Other effects of climate change caused by greenhousegases include extreme weather, food supply disruptions, and increased wildfires.
Carbon dioxide, methane, nitrousoxide, hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and ozone are the main greenhouse gases whose concentrations are increasing in the loweratmosphere.
Thus, the correct option is A.

B. produce mucus that protects parts of the digestive organs from the effects of powerful enzymes needed for food digestion
C. secrete buffers in order to keep the pH of the digestive tract close to neutral
D. provide protection against invading bacteria and other disease-causing organisms that enter the digestive tract in food
The correct answer is option B, kingdom→phylum→class→order→family→genus→species
Reason:
There are basically seven orders of classification in Linnaeus's Classification System (in present time) arranged in descending order
Kingdom→phylum→class→order→family→genus→species
The Domain is the largest and most inclusive group and consists of organisms that share few characteristics while the species is the smallest and most exclusive group and consists of organism that possess similarity up to an extent where they can breed among themselves to produce offsprings.
a. True
b. False
Answer Explanation:
A radio uses an electromagnetic energy in the form of radiant energy. This is an invisible energy in the form of radio waves that can travel through space.
When it comes to radio, the radio waves are received by the radio tuner. It is then converted into sound waves that are audible to the human ears. Unlike the other electromagnetic radiation, the radio waves are harmless since they do not cause any harm to the human body. This is the reason why, it is more commonly used for telecommunications and toys controlled by remote.
a. True
b. False
The Answer for that question is True.
