Answer:
These underground reservoirs of steam and hot water can be tapped to generate electricity or to heat and cool buildings directly. ... It is simply power derived from the Earth's internal heat. This thermal energy is contained in the rock and fluids beneath Earth's crust.
The correct answer is option 1, that is, there is an evolutionary link between the classes.
The study of one kind of proof of evolution is known as embryology, that is, the study of embryos. An embryo refers to an unborn young in its initial stages. Embryos of various distinct types of animals, that is, mammals, reptiles, birds, fishes, etc. seems very identical and it usually becomes tough to differentiate them apart.
Various traits of one kind of animal are observed in the embryo of another kind of animal. This illustrates that the animals are identical and that they are developed identically, signifying that they are associated, have common descendants and that they began the similar, slowly developing distinct traits, however, the fundamental plan for the beginning of the creature remains similar.
Diet and weightloss advertising puts super skinny models and actors/actresses saying they lost an insane amount of weight using their product. That is completely bias because they aren’t just going to say the model lost weight through other methods of weight loss because they are advertising THEIR product.
I would use skepticism evaluating these ads because I would be skeptical believing that someone lost 200 pounds in 2 months drinking some supplement.
Answer: Cell with membrane potential have EXCITABILITY, thus, the correct option is C.
Explanation:
Membrane potential refers to the difference in electric potentials between the inside and the outside of the cell membranes of living organisms. This difference in electric potential give the cell membranes the ability to receive and to respond to stimuli, this ability is called excitability.
The central nervous system is responsible for processing stimuli information and sending out appropriate responses to different parts of the body including the muscles. The muscles tissues are able to respond to the directions of the nervous system to contract or to relax because of their ability to be excited due to the potential differences between the outer and the inner plasma membrane.
Answer: The sun
Explanation: Primary producers obtain their energy via the sun through the process of photosynthesis.
