Answer;
The best phrase will be;
<span>Neither benefits nor is harmed
</span>
Explanation;
Commensalism is a type of relationship where organisms of two species in which one species obtains food or other benefits from the other without harming it.
Commensal is the organism that benefits from the relationship or association.
Answer:
They reproduce.
Explanation:
Reproduction is the phenomenon which involves the production of an offspring by particular individual or individuals to propagate their species. Reproduction is done during reproductive phase. Unicellular organisms are single-celled forms whereas multicellular organisms are made up of many cells.

Answer:An explosion disturbs the gas and dust in the nebula.
Explanation: Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust. Squeezing made the cloud start to collapse, as gravity pulled the gas and dust together, forming a solar nebula . Just like a dancer that spins faster as she pulls in her arms, the cloud began to spin as it collapsed. Eventually, the cloud grew hotter and denser in the center, with a disk of gas and dust surrounding it that was hot in the center but cool at the edges. As the disk got thinner and thinner, particles began to stick together and form clumps. Some clumps got bigger, as particles and small clumps stuck to them, eventually forming planets or moons . Near the center of the cloud, where planets like Earth formed, only rocky material could stand the great heat. Icy matter settled in the outer regions of the disk along with rocky material, where the giant planets like Jupiter formed. As the cloud continued to fall in, the center eventually got so hot that it became a star, the Sun, and blew most of the gas and dust of the new solar system with a strong stellar wind. By studying meteorites , which are thought to be left over from this early phase of the solar system, scientists have found that the solar system is about 4,600 million years old!
Fires disrupt the equilibrium of an ecosystem. The results of a fire include a resetting of plant succession. Many ecosystems have adapted to a certain frequency and intensity of wildfires, and many plant species actually require fires as part of their life cycles. Fires can open up forests and grasslands that would be too congested and shaded to allow young grasses or trees to take root. Fires in fact act as a stimulus for some seeds to germinate. These would typically be pioneer plants that are able to grow in fairly harsh and varied conditions. Fires also remove accumulated dead tree matter that can accumulate in a forest, and if wildfires are too infrequent, fires and be very intense when they do happen as they are fed by the accumulated material.
Answer:
A) maximizes light absorption by the chloroplasts for photosynthesis
Explanation:
Chloroplasts are the double membrane-bound organelles present in the leaf cells. Chloroplasts contain light-absorbing pigment chlorophyll that absorbs maximum light of blue and red wavelengths.
Absorption of light by chlorophyll pigments drives the light reactions of photosynthesis which in turn provide ATP and NADPH to fix carbon dioxide gas into glucose by light-independent reactions. The process of photosynthesis produces glucose which in turn serves as an energy source for plants and supports their growth and development.
Therefore, exposure to blue light increases the rate of photosynthesis as chloroplasts in the leaf cells are aligned to absorb maximum blue light to support photosynthesis. And a higher rate of photosynthesis produces more glucose to support the growth of the plants.
