Explanation:
In a stable or predictable environment, asexual reproduction is an effective means of reproduction because all the offspring will be adapted to that environment. In an unstable or unpredictable environment asexually-reproducing species may be at a disadvantage because all the offspring are genetically identical and may not have the genetic variation to survive in new or different conditions. On the other hand, the rapid rates of asexual reproduction may allow for a speedy response to environmental changes if individuals have mutations. An additional advantage of asexual reproduction is that colonization of new habitats may be easier when an individual does not need to find a mate to reproduce.
Answer:
how old the star is
Explanation:
There are many characteristics that affect the brightness of stars. If two stars are the same temperature, same age, and same distance from the Earth, the larger one will appear brighter. If the temperature, age, or size is different, the one closest to Earth will appear brighter, even if that is the smaller one.
True.
Explanation:
Lifestyle behaviors and environmental factors account for around 70-90% of cancer cases, according to new research published in the journal Nature.
The smallest energy unit is joule (J) followed by British thermal unit (Btu), Calorie (kcal) and Kilowatt0hour (kWh). 1 joule is equivalent to 1 newton meter; 1 BTU is equivalent to 1055 joules; 1 calorie is equivalent to 0.0003969 BTU and 1 kWh is equivalent to 3,413 BTU.
