Answer:
Explanation:
The Earth's Three Motions. The Earth turns (rotation around the polar axis), goes along on its orbit (revolution around the Sun), swings smoothly as un unbalanced spinning top (equinoctial procession)
The light reaction transfers two electrons through the electron transport chain.
Answer:
At meiosis II in the mother
Explanation:
Both the parents have normal vision but both the sons are colorblind. Since colorblindness is X linked recessive disorder, the sons have obtained the allele for colorblindness from mother. This makes the mother carrier for colorblindness. The genotype of the mother is X^cX. The young man with Klinefelter syndrome is colorblind which means that he is homozygous recessive for the allele of colorblindness. His genotype is X^cX^cY. Since this man has obtained two copies of the allele of colorblindness, the mother must have experienced nondisjunction at meiosis II during gamete formation.
Anaphase-II of meiosis II separates and segregates the sister chromatids (now called daughter chromosomes) to opposite poles. Failure of segregation of two copies of X^c chromosome of mother to opposite poles and their distribution to the same egg cell resulted in the formation of an egg with two copies of X^c chromosome. Fertilization of this egg with a sperm carrying "Y" chromosome as sex chromosome resulted in a zygote with X^cX^cY that developed into the man with Klinefelter syndrome and colorblindness.
Any no live no part of the environment, such as sunlight, heat, precipitation, humidity, wind or water currents, soil type, and so on.
Answer:
Otros científicos incluyen: Niels Bohr, J.J. Thompson, Ernest Rutherford, James Chadwick y Ernest Schrodinger
Explanation:
El modelo de Bohr se centró en el núcleo del átomo rodeado de electrones que giran a su alrededor. J. J. Thompson propuso electrones rodeados por alguna carga positiva para equilibrar el poder de los electrones que estaban cargados negativamente. El modelo de Ernest Rutherford propuso que los protones y los neutrones residían dentro del núcleo del átomo con los electrones distribuidos alrededor del núcleo. A James Chadwick se le atribuyó el descubrimiento de neutrones (que poseen carga neutral) en su modelo, contribuyendo así al modelo atómico. Ernest Schrodinger avanzó el modelo de Bohr al indicar claramente los orbitales a través de los cuales los electrones giran alrededor del núcleo de un átomo.
