The answer is D! living things are made up of units called cells.
Answer:
Geo thermal : Nuclear reactions
Bio mass : plants
Solar : sun rays
Hydro power : Water
Explanation:
Geothermal energy is also used to directly heat individual buildings and to heat multiple buildings with district heating systems. Hot water near the earth's surface is piped into buildings for heat. A district heating system provides heat for most of the buildings in Reykjavik , Iceland.
The major biomass sources currently used are sugar cane and corn to produce bioethanol , and rapeseed for biodiesel production. Other sources are also used such as sunflower seeds, soybean, canola, peanuts, jatropha , coconut and palm oil for biodiesel, and wheat, sugar beet, sweet sorghum and cassava for bioethanol
Conversion of energy from sunlight into electricity
Hydropower or water power is power derived from the energy of falling or fast-running water, which may be harnessed for useful purposes.

Answer;
B) all levels of organization within an organism are interdependent.
Explanation;
-The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
The levels of organization are dependent on each other, for example, the organ systems rely on each other for many different things and cannot function without the other. e.g. The nervous and endocrine systems control the activities of the digestive, excretory, circulatory and respiratory systems. Organ systems need to work together to maintain homeostasis in the body.
Answer:
D
Explanation:
Atomic radius is the distance from the atom's nucleus to the outer edge of the electron cloud. In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant.
