Answer:
El entrecruzamiento cromosómico es un proceso biológico que ocurre durante la meiosis, cuando las parejas de cromosomas homólogos, o del mismo tipo, están alineadas. Durante la meiosis los cromosomas emparejados están alineados en las llamadas placas meióticas, y tienen un mecanismo biológico que los mantiene unidos.
Answer:
The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.
Explanation:
Actually, the mitochondria does not MAKE the energy, it just makes it usable to the cell! It is through cellular respiration that this can take place.
Thank you for the opportunity to respond to you, and I hope this helped. I wasn't exactly sure what you were asking... if you would like more help, I would be more than happy to assist you!!!
Answer:
i just took this test and the answer is C
Explanation:
Your answer is A ; weathering and erosion
Explanation:
On the surface weathering and erosion break down igneous rocks into pebbles,sand and mud ,creating sediments which accumulates in basins on the Earth's surface
