What happens when light energy excites electrons in photosystem II?
Vlada [557]

Answer:

C. Electrons are released into the electron transport system.

Explanation:

Photosynthesis has both light dependent processes and light-independent processes. In the light-dependent reactions, photosystem II is the first protein complex. Photosystem II is present in the thylakoid membrane of plants.

<em>When the photons or light energy hits photosystem II, the free electron excites and released into the electron transport system (series of proteins). </em>The electron then passes through electron transport system and the energy from the electron fuels the hydrogen ions to move against their concentration gradient. Once the energy is utilized, the electron is accepted by photosystem I.

Hence, the correct option is C.

Answer:

In the above experiment, these three flies are not enough cogent

Explanation:

Because in the above experiment which is designed to test that, in the above cage these three flies prefer which type of food either it is a banana which is fresh or either apple which is rotten. But the behavior of the flies is not the same, so it is difficult to judge where the flies spend more time. It is a probability that the flies spend most of the on a fresh banana or a rotten apple or both fruits.

These three flies could be unusual.

Give the source of information (author, title, source,pages
Mila [183]

There are microorganisms that are able to live in extreme environments under adverse conditions of pH, temperature and salinity. These microorganisms are classified as extremophiles.  Within the group of extremophiles there are halophilic bacteria, which are those capable of living in extremely saline environments.

One biological factor that all living things are subject to suffer from is osmotic pressure. Halophilic microorganisms have developed mechanisms to adapt to saline environments where osmotic pressure acts with great intensity on individuals. These bacteria change the chemical composition of their membranes and also accumulate osmoprotective compounds in their cytoplasm to compensate for osmotic stress.
