Answer: we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can!
The answer is <span>C. glycolysis, Krebs cycle, electron transport</span>
Cellular respiration includes glycolysis, link
reaction, Krebs cycle, and electron transport chain (ETC), in that order. The
main function of ETC is a production of ATP. In this series of
oxidation-reduction reactions, electrons from the previous stages of cellular
respiration are taken and transported to the oxygen which is the final acceptor
of electrons. As the result, water and ATP are produced.
Answer:
Hay tres clases principales de moléculas de lípidos de membrana: fosfolípidos, colesterol y glicolípidos. Las composiciones de lípidos de las monocapas internas y externas son diferentes, lo que refleja las diferentes funciones de las dos caras de una membrana celular.
Explanation:
Answer:
Independent: type of fertilizer
dependent: plant growth
control: soil, seed, water, type of pot, environment/amount of sunlight, air quality, etc.
Explanation: Think about it like this: the dependent variable DEPENDS on the independent variable. The fertilizer will control how tall the plant grows (if there is a relationship between them). Then the control variable is ANY VARIABLE that remains the same in all trials. You can only manipulate one variable (have one independent variable) or else the experiment is not valid.
