Tropical cities have low climate and have rainy weather
Answer:
6 genotipos y 4 fenotipos
Explanation:
La codominancia es un tipo de interacción alélica donde ninguno de los dos alelos puede enmascarar la expresión del otro alelo, produciendo de este modo un fenotipo diferente en presencia de ambos alelos (es decir en individuos heterocigotas). Un ejemplo de alelos codominantes son los alelos A y B del grupo sanguíneo, los cuales se expresan en individuos heterocigotos. Por otra parte, un alelo recesivo sólo puede expresarse en individuos homocigotas que portan dos copias del mismo alelo recesivo. El caso del grupo sanguíneo es idéntico a la pregunta planteada, ya que en este caso tenemos dos alelos codominantes entre sí (alelos A y B) los cuales son dominantes respecto al alelo O recesivo. En este caso, de la combinación de alelos pueden resultar seis genotipos (IAi; IAIA; IBi; IBIB; ii; AB) y cuatro fenotipos (tipo de sangre A, tipo de sangre B, tipo de sangre AB y tipo de sangre O).
While women inherit 50% of their DNA from each parent, men inherit about 51% from their mother and only 49% from their father.
Answer:
chemical reactions involve collisions between molecules. most collisions don't have either the right orientation or enough energy for the reaction to proceed. the molecules just bounce off each other, unchanged. incidentally that is why reactions proceed faster as the temperature increases - high temperature means molecules are moving faster

Answer:
The given statement is false.
A neuron is the basic structural and functional unit of the nervous system. It helps in transmitting information from one neuron to another neuron, gland, or muscle cell.
The conduction of nerve impulse is electrochemical in nature. It transmits the impulse electrically through the axon the nerve cells and chemically through synapses (gap between two nerves cells).
The axon terminals of pre-synaptic nerve cell release chemical messengers (also called neurotransmitters) in the synaptic cleft. These messengers then bind to the receptors present on the post-synaptic nerve cell and regenerate the nerve impulse.
