Answer:
they were discovered by Robert Hooked in 1665. It looked like similar to cellua.
Answer:
Atoms are electrically neutral as a result of having an equal amount of positive (due to the protons) and negative (due to the electrons) charges on it.
An ion generally is an electrically unbalanced atom (i.e an atom with a net charge on it)
A negative ion called an anion is produced when an atom gains an extra electron from a neighboring atom, giving it an extra negative charge. This can be produced by ionization with a radioactive radiation or simply by dissolution.
A positive ion is called a cation and it is produced when an atom loses electron to a neighboring atom. The loss of this electron causes the positive charges to outweigh the negative charges in the atom. Cations can be produced by radioactive radiation ionization of an atom or by simple dissolution.
The subatomic particle that is negative is the 'electron'.
Answer:
Explanation:
the MWMT should not exceed 17-18ºC, and daily maximum temperatures should not exceed 21-22ºC to be fully protective of adult steelhead migration.
Answer: Adenina
Explanation:
Base nitrogenada: una molécula que contiene nitrógeno y tiene las propiedades químicas de una base. Las bases nitrogenadas en el ADN son adenina (A), guanina (G), timina (T) y citosina (C). Las bases nitrogenadas en el ARN son las mismas, con una excepción: adenina (A), guanina (G), uracilo (U) y citosina (C).
Metabolism, respiration and digestion are all complex chemical processes involving many steps, happening in 3 dimensional space within cells. Metabolism is the breaking of bonds within food molecules (like sugar) to harness energy for cellular work; respiration involves moving oxygen and carbon dioxide gases between cells to facilitate cellular metabolism and digestion involves breaking down food macro structures into smaller units suitable for metabolism.
So the answer is D - each of the three process involve multiple chemical reactions.
