Answer:

a. Australopithecine Afarensis

Explanation:

With a skull of 3 million years, scientists have been able to prove the existence of Australopithecus afarensis, the oldest ancestor of humanity. 4 million years ago, humanity did not exist. But at least one creature bore in its bones what would be the hallmark of Homo sapiens. Australopithecus afarensis, that creature's name, had a tiny brain. But it stood like no monkey could do, representing an ancestral trait that would be passed from generation to generation to modern man.

Which of the following would most likely be key to gathering evidence that the RNA World hypothesis is valid?
muminat

Answer:

The answer is; Simulation of early Earth conditions and long-term study of the resulting molecules

Explanation:

It is believed that the first molecules on earth were made spontaneously through reaction spurred by energy from lightning and also the heat from the earth. It is believed that these molecules over time then formed polymers through the catalysis by metals in the oceans. These polymers were able to self-replicate and also act as enzymes since they were able to fold up. This hypothesis was coined by Carl Woese, Francis Crick and Leslie Orgel in the 1960s. To prove it, the then conditions of early earth need to be replicated, data collected, and analyzed.

What hormone released by the highlighted structures inhibits the secretion of FSH only?
soldi70 [24.7K]

Inhibin inhibits the secretion of FSH only.

<h3>What is the role of inhibin?</h3>
  • Inhibin is a protein mainly produced by the gonads.
  • In men it is produced by the Sertoli cells and it is produced by the granulose cells in women.
  • It negatively regulates the secretion of Follicle Stimulating hormone (FSH) from the pituitary gland.
  • FSH itself induces the production of inhibin for negative feedback.
  • Pituitary is a pea shaped endocrine gland present at the base of the brain. It is the major endocrine gland and controls growth, development and functions of other endocrine glands.
  • Hormone activin has opposite effect to inhibin. It enhances FSH biosynthesis and secretion.

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.
