Which statement best describes the relationship of photosynthesis and energy?

Biology
1 answer:
NemiM [27]3 years ago
4 0

Answer:The process of photosynthesis is energy-releasing because the process converts light energy into free energy that can be

used for cell functions.

Explanation:

Photosynthesis is a process used by green plants to convert light energy into chemical energy that is later released to fuel the organisms' activities. ... In these light-dependent reactions, some energy is used to release electrons from suitable substances, such as water, producing oxygen gas.

Answer: The correct answer is option C

FACILITATED DIFFUSION.

Explanation: FACILITATED DIFFUSION is a form of passive transport,it is the process by which substances(molecules) move from a region of higher concentration to a region if lower concentration along their concentration gradient through the help of a membrane transporter forming a pore or channel(Protein).

Facilitated diffusion dies not require high energy to occur since a concentration gradient is involved.

The reactivity of an atom arises from
saw5 [17]

Answer:

B

Explanation:

For metals, the further away the valence electrons are from the nucleus, the higher the reactivity of the elements. Unlike halogens that are more reactive if the valence orbital shells are closer to the nucleus. This is due to ionization energies – which is the minimum energy required to discharge an electron from its orbit.

For metals this should be lower because they need to lose electrons to attain a stable electron configuration. For halogens it should be high because they don't need to lose electrons, but rather gain, in order to attain stable electron configuration.

Electrons in their orbital shells need to occur in pairs (with opposite quantum states) to be in stable configuration and as long as an atom has orbitals with single electrons, the atoms will be reactive as opposed to when its orbitals are ‘full’.
