Answer:

The correct answer would be option D.

mRNA is formed after transcription of the DNA.  

It carries the nucleotide sequence of the DNA to the ribosome in the form of codon sequence for translation, that is, the formation of the polypeptide chain.

The codon sequence of the mRNA codes for the amino acid sequence of the protein.

eduard

Answer: Anconeus muscle

Explanation:

The anconeus is a small muscle found at the elbow. It is Attached to the humerus and ulna (it originates on the lateral epicondyle of the humerus and inserts on the olecranon process and superior portion of the ulna). Anconeus muscle allows the forearm to extend and it also provides support for the dorsal joint capsule and the ulna as well.

The radial nerve permits the anconeus muscle to carry all of those functions.

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.

<u>Evolution is sometimes a controversial:</u>

Evolution is the most scientific explanation about how the life forms of earth originated and turned into the form that we see today.

I don’t think there should be a controversy because there is no other explanation that proves to be more logical than the theory of evolution. Evolution is a theory that has several supporting proofs and the theory itself was formed after several years of detailed study and observation.

I don’t think alternatives to evolution should be taught at schools. Alternative theories to evolution are based on various religious beliefs which lack a scientific basis.

Schools should be a place that enables students to do productive scientific thinking and teaching alternatives to evolution wouldn’t be a good idea.

The quantity of each type of organelle in a cell varies depending on the tasks the individual cell must perform. If a scientist
tester [92]

The correct answer is option C. A leaf growing in full sunlight

The chloroplast is an organelle, which helps the plants to carry out the process of the photosynthesis. The leaves are the main site of the photosynthesis in the plants, hence, they have an abundant number of chloroplasts present in the cells. In the presence of the sunlight, they perform the light dependent reactions of the photosynthesis process. In case, a scientist find out the cell, which have a high number of chloroplast, then the cell must be specialised to perform photosynthesis, hence, the cell would belong to the leaves, which are growing in full sunlight.
