Answer:
A. Passive Transport is migration of a molecule from one side of the cell membrane to the other, from an area of high electrochemical potential to a region of lower electrochemical potential.
B. Diffusion is an individual molecule of a material moving from a high-concentration location to a low-concentration area over a semipermeable barrier
C. Osmosis is the movement of molecules of water through a cell's partly permeable membrane from a liquid with a large concentration of water molecules to a solution with a lower concentration of water molecules.
D. Facilitated Diffusion are molecules that diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.
E. Active transport is the transport of molecules across a cell membrane against a concentration gradient from a low-concentration region to a high-concentration region.
F. Selectively permeable is when some chemicals or ions pass across the membrane, while others are blocked.
G. Cellular respiration are organisms mix oxygen with food molecules, directing the chemical energy in these substances into life-sustaining processes while eliminating carbon dioxide and water as waste material.
Explanation:
4 neutrons that are produced along with the Zn and sm. The complete final equation is: ²³⁵U + ¹n → 
+ 4 n
<h3>What atomic mass?</h3>
Atomic mass, the quantity of matter contained in an atom of an element.
1) In the left side of the transmutation equation appears:
²³⁵U + ¹n →
Deleting the atomic number (subscript to the left) because the question does not show them as it is focused on a number of neutrons.
2) The right side of the transmutation equation has:
→ +?
3) The total mass number of the left side is 235 + 1 = 236
4) The total mass number of Zn and sm on the right side is 160 + 72 = 232
5) Then, you are lacking 236 - 232 = 4 unit masses on the right side which are the 4 neutrons that are produced along with the Zn and sm.
The complete final equation is:
²³⁵U + ¹n → + 4 n

Answer:
La afirmación es verdadera.
Explanation:
El método científico es un método de investigación usado principalmente en la producción de conocimiento en las ciencias y se define como un procedimiento para tratar un conjunto de problemas. En ciencia, el método científico es la estrategia para la investigación y la exploración de lo desconocido.
Por lo que el método científico es el procedimiento mediante el cual es posible alcanzar un conocimiento objetivo de la realidad, tratando de dar respuesta a las interrogantes acerca del orden de la naturaleza.
Para ser científico, un método de investigación debe basarse en la empírica y en la medición, sujeto a los principios específicos de las pruebas de razonamiento.
El método científico se basa en la reproducibilidad, es decir, la capacidad de repetir un determinado experimento, en cualquier lugar y por cualquier persona, y la refutabilidad, es decir toda proposición científica tiene que ser susceptible de ser falsada o refutada.
Entonces <u><em>la afirmación es verdadera.</em></u>
