Answer and explanation;
-All lipids contain carbon, hydrogen, and oxygen. Some of them also contain nitrogen and phosphorus. The four main classes of lipids are fats, waxes, sterols, and phospholipids. Fats are triglycerides.
-The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes.
-Lipids are water-insoluble (hydrophobic), and this property is put to great use in the organisation of cells and tissues.
For example; phospholipids are a class of lipids that is amphipathic; that is it contains fatty acid tails that are hydrophobic, and a phosphate head that is hydrophilic. This means the phosphate group will orientate itself towards water and away from the rest of the molecule, and also gives rise to the special properties that allow phospholipids to be used to form membranes.
The beneficiaries of the behavior are related to the individual performing it. Groups that differ in terms of altruistic and selfish genotypes have differential reproduction or survival.
<h3>What is Altruistic behavior ?</h3><h3 />
Altruism is the practise of acting in a way that benefits another person at the expense of oneself. Giving someone else your lunch, for instance, is altruistic since it satisfies their need while also leaving you hungry.
Nepotistic altruism, reciprocal altruism (or mutualism), group-based altruism, and moral altruism are the four categories of altruism.
- Along with cortical areas like the medial prefrontal cortex and the temporoparietal junction, the desire to act altruistically is linked to higher activity in limbic areas like the nucleus accumbens and anterior cingulate cortex.

Answer:
photosynthesis produces glucose which is stored as starch in the plant.
Explanation:
6H₂O + 6CO₂ -----> C₆H₁₂O₆ + 6O₂(as a waste product for plants)
Photosynthesis reduces carbon dioxide in the atmosphere which reduces the green house gasses in the atmosphere which reduces the green house effect.
