Answer: Option (A) is the correct answer.

Explanation:

Atomic number of lithium is 3 and mass number is 7. It is known that atomic number represents the number of protons present in an atom and mass number is the sum of total number of protons and neutrons present in an atom.

Also, it is known that in a neutral atom number of protons equal number of electrons.

Therefore, in a lithium atom there are 3 protons, 4 neutrons and 3 electrons.

Atomic number of helium is 2 and its mass number is 4. Therefore, in a helium atom there are 2 protons, 2 neutrons and 2 electrons.

Hence, we can conclude that lithium has more protons, neutrons, and electrons as compared to helium.

É correto afirmar que a presença de lagartas em espigas de milho se deve:
slavikrds [6]

Answer:

C - ao desenvolvimento de ovos depositados por borboletas.

Explanation:

Antes de responder a sua pergunta, eu preciso te explicar que esse não é o servidor brasileiro e sim o servidor dos EUA, você deve ter percebido que toda a linguagem do site esta em inglês. Isso significa que você só deve postar perguntas em português no campo "World Languagens" mesmo que a sua pergunta seja de biologia como essa. Caso você não faça isso, a sua pergunta pdoe ser excluída, sem ser respondida.

As lagartas que surgem nas espigas de milho, são resultado do ciclo de vida da lagarta e refere-se ao momento em que os ovos depositados nas plantas de milho pelas borboletas se chocam, liberando as lagartas, que se desenvolverão e virarão novas borboletas.

É impossivel que um grão e milho vire uma lagarta, ou que o sabubo apodrecido pode gerar lagartas. Além disso, o ´processo de geração espontanea é uma teoria cientifica invalida e que não deve ser considerada.
