Answer:

an extinct plant or animal

Explanation:

Fossils of an animal or plant refers to its preserved or mineralized remains. Fossils have proven to be an integral part of tracing life back. Among the very many usefulness of keeping fossil records of plant and animals, one of them is discovering the evolutionary relationships between these organisms.

Fossils of plants or animals are compared with that of a present organism to discover how related they are. However, a difficulty that arises during this comparative procedure is that the fossils about to be compared may be from an extinct plant or animal.

Solar, wind, and hydroelectric energy<br> are examples of<br> resources.
strojnjashka [21]

Answer:

Renewable Energy Resources.

Explanation:

Unlike fossil fuels which cannot be recovered when destroyed, these sources of energy can be recovered by a means of recycling . Recycling here reduces solid wastes which is one of the causes of land pollution.

Hydroelectric schemes can only be built in mountain regions where rainfall and rivers are plentiful which involves upset of aquatic ecosystem. This poses a dangerous pollution problem though.

Wind generators and solar panels are not very efficient energy producers. However, future schemes for producing solar energy via solar satellites are promising.

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.
