Además de Dalton, ¿qué otros científicos propusieron nuevas ideas y modelos del átomo?
Lera25 [3.4K]

Answer:

Otros científicos incluyen: Niels Bohr, J.J. Thompson, Ernest Rutherford, James Chadwick y Ernest Schrodinger

Explanation:

 El modelo de Bohr se centró en el núcleo del átomo rodeado de electrones que giran a su alrededor. J. J. Thompson propuso electrones rodeados por alguna carga positiva para equilibrar el poder de los electrones que estaban cargados negativamente. El modelo de Ernest Rutherford propuso que los protones y los neutrones residían dentro del núcleo del átomo con los electrones distribuidos alrededor del núcleo. A James Chadwick se le atribuyó el descubrimiento de neutrones (que poseen carga neutral) en su modelo, contribuyendo así al modelo atómico. Ernest Schrodinger avanzó el modelo de Bohr al indicar claramente los orbitales a través de los cuales los electrones giran alrededor del núcleo de un átomo.

Which type of macromolecule ( protein , carb , nucleic acid , or lipid ) is ATP & ADP ?
Ad libitum [116K]

Answer:

ATP & ADP  are nucleic acids.

Explanation:

ATP and ADP are macromolecules of nucleic acids as they are made up of structures similar to DNA.

An ADP molecule is made up of two phosphate groups, a sugar backbone (ribose) and the nucleotide adenine.

An ATP molecule is made up of sugar backbone, three phosphate groups and the nucleotide adenine.

Hence, Both the structures are similar to DNA and RNA. As the structures contain nucleotides hence ATP and ADP are nucleic acids macromolecules.

What is the "first second" in relation to the Big Bang theory?
dybincka [34]

Explanation:

This process is known as nucleosynthesis. But the universe was still too dense and hot for electrons to join these nuclei and form stable atoms. That's a busy first second. Next we'll find out what happened over the next 13 billion years.

Use this information to answer questions 6 - 11. Your original population of
grigory [225]

Answer:

1. How did the tidal wave  affect the predicted frequencies of the alleles in the population?

No changes

2. What is the frequency of the recessive allele?

q= 0.6

Explanation:

If we assume that all individuals were equally likely to be wiped out, that means the frequency/ratio of the gene and genotype of the population will not change. The tidal wave killing 100 out of 200, so it simply makes the population become half of it used to be.  

If the population at equilibrium, we can use the Hardy-Weinberg formula to find out the expected frequency of the dominant and recessive alleles. There are 36 homozygous recessives out of 100, so the frequency of the recessive allele will be:

q^2 = 36/100

q= √36/100= 6/10= 0.6
