Biology
1 answer:
Mkey [24]3 years ago
6 0

Answer:

Functions of epithelial cells include secretion, selective absorption, protection, transcellular transport, and sensing. Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane

If a TRNA had a AGC anticodon it could attach a
Contact [7]

A transference RNA (tRNA) is an adapter molecule that decodes a codon messenger RNA (mRNA) during the synthesis of a polypeptide chain. These molecules (tRNAs) play a fundamental role during translation.

  • If a tRNA had an AGC anticodon it could attach a codon having the sequence UCG.

  • During translation, tRNAs act at specific sites in a ribosome to synthesize a polypeptide chain (i.e., a protein) from an mRNA sequence.

  • The anticodon of the tRNA binds by base complementary to a triplet of nucleotides or 'codon' in the messenger RNA (mRNA) during protein synthesis (i.e., translation).

  • According to the base complementarity rules, in RNA, Adenine always pairs with Uracile (Thymine in DNA), whereas Guanine always pairs with Cytosine.

Diferença entre soluções líquidas e líquidos puros
vladimir1956 [14]

Portuguese version:

Não falo português mas:

Uma solução é formada quando algo é adicionado ou dissolvido em um líquido. Você faz uma solução quando adiciona sal ou açúcar a um copo de água. ... Desde que um líquido seja feito de uma única substância, ele permanece puro e é chamado de líquido. Quando algo é adicionado a ele, ele se torna uma solução.

English version: I don't speak Portuguese but:

A solution is formed when something is added or dissolved in a liquid. You make a solution when you add salt or sugar to a glass of water. ... As long as a liquid is made of a single substance, it remains pure and is called a liquid. When something is added to it, it becomes a solution.

Spanish version: No hablo portugues pero:

Se forma una solución cuando algo se agrega o se disuelve en un líquido. Usted hace una solución cuando agrega sal o azúcar a un vaso de agua. ... Mientras un líquido esté hecho de una sola sustancia, permanece puro y se llama líquido. Cuando se le agrega algo, se convierte en una solución.

fReNcH vErSiOn: Je ne parle pas portugais mais:

Une solution se forme lorsque quelque chose est ajouté ou dissous dans un liquide. Vous faites une solution lorsque vous ajoutez du sel ou du sucre à un verre d'eau. ... Tant qu'un liquide est constitué d'une seule substance, il reste pur et s'appelle un liquide. Quand quelque chose y est ajouté, cela devient une solution.

Ok, terminei, tchau.

Okay, I'm done, Bye.

Bien, he terminado, adiós.

D'accord, j'ai fini, au revoir.

What role does the somatic nervous system play?
Afina-wow [57]

Answer:

b. It converts messages that are received from the central nervous system into involuntary reflexes.

Explanation:

The somatic nervous system (SNS) is part of the peripheral nervous system (SNP), which is responsible for transmitting motor and sensory information both back and forth to the central nervous system (CNS).

The main function of the somatic nervous system is to connect the central nervous system to the organs, muscles and skin. This allows us to perform complex movements and behaviors. Somatic neurons carry messages from the external areas of the body that are directly related to the senses. The information captured by the sensory systems is transmitted to the central nervous system. The CNS then sends signals through the nervous networks of the somatic system to the muscles and organs.
