A space probe lands on a planet with 1/2 the gravitational force as the earth. What happens

Planet with 1/2 the gravitational force as the earth. the effect of  the mass and weight of the space probe is described below.

Explanation:

  • At an altitude of 2642 km (approx. 1641 miles) above the Earth's surface, the gravitational acceleration will be 4.89m/s^2, which is half of 9.78 m/s^2 (the gravity at the surface).
  • When the distance between the 2 objects is halved, the gravitational force between the 2 objects is doubled. when the distance between the 2 objects is doubled then the gravitational force doubles.
  • Yes, a space probe that weighs 1000 pounds (excluding fuel) sitting in its launch vehicle on the launch pad will weigh much more from launch until the rocket's engines shut off. At that point it will become weightless. It becomes weightless because it's in free fall, even though it is still heading away from the Earth.
  • In space without gravity pulling down on them, Astronauts are essentially weightless. It is important to explore the difference between mass and weight. ... However, if we went from Earth to Mars, our weight would change because Mars has less gravity than Earth. Gravity is a force pulling matter together.

What peptide would be made by translation from a synthetic mRNA made of the repeating dinucleotide CGCG…?
RSB [31]

Answer:

The question lacks options, the options are:

A. a polymer of arginine plus a polymer of alanine

B. the peptide Met–Arg–Ala–Arg–Ala…

C. a polymer of alanine: Ala–Ala–Ala…

D. a peptide containing alternating arginines and alanines

E. a polymer of arginine: Arg–Arg–Arg…

The answer is D

Explanation:

Translation is the second process of protein synthesis (gene expression) where the mRNA molecule produced during transcription is used as a template for the synthesis of amino acid sequences, which species a particular polypeptide.

The nucleotides in the mRNA are read in a group of three in the ribosome. This triplet nucleotide is called CODON. Each codon specifies a particular amino acid and a collection of all codons constitutes the GENETIC CODE. Hence, in a case where dinucleotide CG is repeated in a sequence. The sequence will read:

CGC GCG CGC GCG CGC GCG..........

In the genetic code, codon CGC and GCG codes for arginine and alanine amino acids respectively. Therefore, if the CG dinucleotide keeps repeating, the nucleotides will be read three at a time, and the amino acid sequence will alternate between those two amino acids (Arginine and Alanine).

So we would have a peptide sequence looking like:

Arg-Ala-Arg-Ala-Arg-Ala-Arg...........

Porque los bioelementos y las biomolegulas son importantes para todos los organismos
miss Akunina [59]

Explanation:

Bioelementos

De los más de 100 elementos encontrados en la Tabla periódica, la materia viva está

constituida por unos 70 elementos y solo alrededor de 21, son esenciales para el desarrollo y

conservación de la vida. Estos elementos se llaman bioelementos o elementos biogénicos.

Bioelementos Primarios

Están formados por: C, H, O, N, P y S, los cuales constituyen alrededor

del 96.2% de la materia viva en base seca. Son los componentes

fundamentales de las biomoléculas. Son iimprescindibles para formar:

carbohidratos, lípidos, proteínas y ácidos nucleicos.

Clasificación de

los bioelementos

Bioelementos Secundarios

Grupo comprendido por los iones: Na+

, K+

, Ca2+, Mg2+, Cl-

. Estos

elementos aunque se encuentran en menor proporción que los

primarios, también son indispensables para los seres vivos. En medio

acuoso (solvente presente en células tejidos y órganos), siempre se

encuentran ionizados.

Oligoelementos

Son aquellos bioelementos que se encuentran en los seres vivos en un

porcentaje menor del 0.1%. Algunos, los indispensables, se encuentran

en todos los seres vivos, mientras que otros, variables, solamente los

necesitan algunos organismos. En este grupo se encuentran: Fe, Cu,

Zn, Mn, I, Ni y Co (que aparecen en la mayoría de los organismos) y Si,

F, Cr, Li, B, Mo y Al (sólo están presentes en grupos concretos).

Constituyen menos del 0.1% y son esenciales para desempeñar

procesos bioquímicos y fisiológicos.
