The sun appears to cross the plane of Earth's equator
when it reaches either one of the "equinox" points in the sky.
The mechanics of cytokinesis are not yet completely understood, but a great deal is known about the critical timing of its events and other aspects of the final step in the cycle of any one cell. The four stages of cytokinesis are initiation, contraction, membrane insertion and completion .
Answer:
B. preservation of advantageous genetic mutations
Explanation:
The process of natural selection involves the preservation of advantageous genetic mutation in a given population.
Natural selection is one of the key factors that ensures the evolution of organisms.
- Desired traits that are able to survive adverse conditions like disease, food shortage, natural disasters are favored by the process of natural selection.
- Traits that also undergo advantageous genetic mutation in order to get a competitive advantage is also accrued to natural selection.
Photosynthesis, the process which uses light energy to power the combination of carbon dioxide and water to form glucose and oxygen.
Answer:
B. Sphagnum moss takes in energy from sunlight.
D. Euglenas carry out photosynthesis.
Explanation:
According to the question, "a self-feeder" means an autotrophic organism i.e. an organism that produces or obtains food by itself. The process by which an autotrophic organism obtains food is referred to as PHOTOSYNTHESIS. Photosynthesis entails the synthesis of food in form of organic compounds in the presence of sunlight.
Based on this, Euglenas, which is a plant-like protist, carrying out photosynthesis and Sphagnum moss, which is a lower plant (bryophyte) taking in energy from sunlight in order to perform photosynthesis are two examples that describes a "self-feeder"
