Answer:
Atom-Molecule-Organelle-cell-Tissue
Explanation:
Biological is a hierarchical system that arranges biological structures in the order of complexity.
In the given sequence,
- The atom is the simplest and smallest unit
- Molecule-It is made up of two or more atoms
- Organelle-A specialized structure within a cell
- Cell- Is the smallest functioning unit of life and it contains organelles
- Tissue-an assembly of cells that perform a specific function.
Answer:
Profase I
Explanation:
La Profase I es la primera etapa de la meiosis en la cual el material genético se condensa para formar los cromosomas y se desarrolla el huso acromático (huso meiótico). El entrecruzamiento, también conocido como sobrecruzamiento o <em>crossing-over</em> (por su nombre en inglés), es un proceso que consiste en el intercambio de material genético entre cromátidas no hermanas de cromosomas homólogos. El entrecruzamiento se produce durante la Profase I, es decir, durante el período inicial del primer ciclo celular meiótico (meiosis I). El sobrecruzamiento tiene una importancia fudamental desde el punta de vista evolutivo ya que este fenómeno incrementa la diversidad genética de las gametas obtenidas mediante este proceso.
Answer:
8
Explanation:
The fly has only 3 pairs of somatic chromosomes, that means that only can combine 3 chromosomes. To calculate the combinations the exponential 2n it is used. In this case is 2 to the third power that is equal = 2 x 2 x 2 = 8
This fly also has a fourth pair, but this one is the sexual one, so the main function of this gene is to give the sex to the offspring.
The process is called OXIDATIVE PHOSPHORYLATION.
Oxidative phosphorylation is the process by which a free phosphate ion is added to ADP in order to produce ATP. This process take place in the mitochondrion and is a major source of energy for anaerobic organisms. The free phosphate ion is usually transferred from NADH or FADH2.<span />
