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.
Answer:
The fertilized egg goes through mitosis to create many identical copies of the original cell then those cells will differentiate into specialized cells of different tissues.
Explanation:
Insertion mutations can be small, like in the CAGTC example in which only one nucleotide was inserted, or they can be large, with many nucleotides being added. If the number of bases inserted is not a multiple of three, then the insertion mutation is also considered a frameshift mutation.
Hope this helps :D
Answer:
Larva and pupa is present in complete metamorphosis while nymph is present instead of larva and pupa in incomplete metamorphosis.
Explanation:
Complete metamorphosis has four stages i. e. egg, larva, pupa, and adult while the incomplete metamorphosis has three stages i. e. egg, nymph, and adult. Grasshopper, dragonfly, cicada and cockroach have incomplete metamorphosis while ladybug
, housefly, butterfly and honeybee have complete metamorphosis. Both type of insects lay eggs and after hatching a baby insect comes out called larva. After sometime this larva transforms from immature to mature, this stage is known as pupa. After pupa, the insect converts into an adult which is ready for reproduction. Nymph is a stage that comes in place of larva and pupa in incomplete metamorphosis. in this stage, the insect is small in size and lack of wings but in adult stage the wings appear.
