kirill [66]

Answer:

Oh gosh, thank you! (I feel like this'll get deleted, so here are the answers: Tony Stark became Iron man when he was in like this military place? I don't know the exact details, but when people were trying to fight him he made a suit to fight back. The suit was surprisingly powerful, so he re-made it to be more appealing, light-weight, and stronger.

All he has to do is change into his suit. He doesn't actually have any superpowers, unless you consider being really smart a super power)

A certain eukaryotic organism has multiple, distinct genes with highly similar sequences that are expressed at different times i
vlabodo [156]

These genes could have arisen by gene duplication.

<h3>What is gene duplication?</h3>

Gene duplication is the process of copying a section of DNA that codes for a gene. A retro transposition event or a recombination mistake are both potential causes of gene duplication. As a result, the duplicate gene coding may experience a significant number of modifications throughout time. This might prevent the gene from functioning or, in other situations, give the creature a benefit.

Gene duplication is a phenomenon that can happen through a variety of ways:

  • Ectopic Recombination: Uneven crossing-over between misaligned homologous chromosomes during meiosis might result in duplications. A duplication at the exchange site and a reciprocal deletion are the results of this recombination.
  • Replication Slippage: Short genomic sequences can be duplicated as a result of the replication error known as replication slippage. DNA polymerase starts copying the DNA during replication, but eventually the polymerase separates from the DNA, causing replication to stall. The replicating strand is incorrectly aligned when the polymerase reattaches to the DNA strand, which accidentally results in several copies of the same portion.
  • Aneuploidy: When a single chromosome's nondisjunction causes an abnormally high number of chromosomes, this condition is known as aneuploidy. Aneuploidy is frequently damaging and frequently causes spontaneous miscarriages in mammals. Some aneuploid people can survive. For instance, human trisomy 21 causes Down syndrome but is not lethal.

Son músculos antagonistas (unos realizan flexión y otros extensión) los siguientes: * 5 puntos Trapecio- deltoides Bíceps- tríce
Lena [83]

Answer:

Bíceps- tríceps

Explanation:

Los músculos trabajan para generar movimiento mediante la contracción de células musculares. El bíceps y el tríceps son músculos antagonistas presentes en el brazo. Cuando el brazo se acorta, el bíceps funciona como agonista (es decir, se contrae) y hace que los tendones que tiran de los huesos del antebrazo puedan doblarlo. Durante este movimento, el triceps funciona como antagonista, encontrándose en estado de relajamiento. Por otra parte, durante el estiramiento del brazo, las funciones de estos músculos se invierten, con lo cual el tríceps (agonista) se contrae  y el bíceps (antagonista) se relaja.
