jeyben [28]

Question:All known organisms use genetic information to produce protein molecules via the same genetic code. This finding strongly supports the hypothesis that __________.

a) the earliest macromolecules probably arose when lightning struck an oxygen-free atmosphere

b) all organisms are descended from one or a few common ancestors

c) the genetic code readily evolves by natural selection

d) there's only one possible way to encode information in a macromolecule

Answer:

b) all organisms are descended from one or a few common ancestors

Explanation:

Protein synthesis occurs when the nucleotide sequence of the mRNA is read in the form of genetic codes. A specific genetic code specifies the same amino acid in all living beings. For example, the code "UUU" codes for phenylalanine in all the living beings irrespective of their species. This suggests that all the life forms have originated from one or few common ancestors and the genetic code has been preserved during the course of evolution of various species.

<h3>What is Mike Velings talks about?</h3>

Industrial aquaculture has had a wide range of negative effects on the environment, including the overfishing of wild fish to feed carnivorous farmed fish and the escape of farmed fish from their containment, which endangers local wild fish populations.

Lastly, in the words of Mike Velings, We are approaching a worldwide food crisis, he said. At our current rate, we are already taking more fish from the ocean than it can naturally replace, despite the fact that almost 3 billion people rely on the ocean for their food. Mike Velings, an entrepreneur and conservationist, offers a solution in this fact-filled, eye-opening talk: the practice of farming fish. "We need to stop hunting the ocean and start farming it,"

Fase del ciclo celular en el que las células crecen, duplican orgánulos y sintetizan ADN
m_a_m_a [10]

Answer:

Phase of the cell cycle in which cells grow, duplicate organelles, and synthesize DNA.

S phase

Explanation:

 DNA replication occurs in synthesis or in the S phase of the cell cycle. Each chromosome is copied with high fidelity in a process that involves a large number of enzymes. In this process the double strand of DNA breaks down and each individual strand is used as a template for the production of the complementary one. The result is the production of two identical copies of the genetic material.
