Glassy, because luster refers to its ability to shine/sparkle etc
During photosynthesis, the energy used to pump protons comes from ______light_____, whereas in cellular respiration it comes from ______NADH/FADH₂_______.
<h3>What are the steps in photosynthesis?</h3>
- The first step in photosynthesis is the absorption of light by chlorophyll bound to chloroplast thylakoid proteins. The absorbed light energy is used to remove electrons from electron donors such as water to form oxygen.
- The electrons are then transferred to the primary electron acceptor, quinine (Q.). Electrons are further transferred from the primary electron acceptor to the final electron acceptor (usually NADP⁺).
- Proton transfer from the thylakoid lumen to the stroma via the F₀F₁ complex generates ATP from ADP and Pi.
- The NADP and ATP produced in steps 2 and 3 provide the energy, and the electrons power the process of reducing the carbon to a six-carbon sugar molecule.
The first three steps of photosynthesis, are directly dependent on light energy and are thus, called light reactions, while the reactions in the last step are independent of light and thus are termed dark reactions.

The correct answer is resistance stage.
Hans Selye was a very important endocrinologist working in the field of biological stress. He developed the General Adaptation Syndrome (GAS) which is a model describing an animal's response to stress. GAS is comprised of three stages; the alarm, the resistance and the exhaustion stage.
During the resistance stage, the body's glands produce and secrete several hormones which protect the individual from the perceived stressor. Some of the hormones produced at this stage are the glucocorticoids.
Answer:
The energy comes from electrons produced by oxidation of biological molecules.
Explanation: In photosynthesis, the energy comes from the light of the sun.

Answer:
<em>a. Cross-sectional study</em>
Explanation:
A cross-sectional analysis <em>includes at one particular point in time looking at data from a population.</em> Participants are chosen based on specific variables of interest in this type of study.
For developmental psychology, cross-sectional experiments are often used, but this approach is also used in many other fields, including social science and education.
