Answer:
El problema es "¿Cuál es la capacidad de solubilidad de los cristales de yodo en diferentes tipos de líquidos?"
Explanation:
Solubilidad es el término que se refiere a la capacidad de las sustancias (solutos) para disolverse en presencia de líquidos (solventes). Así, podemos decir que si Luís quiere saber si los cristales de yodo se pueden disolver en diferentes líquidos, está intentando solucionar el problema de la capacidad de solubilidad de estos cristales.
En este sentido, podemos decir que el yodo no es una sustancia que se disuelva fácilmente en agua, pero sí se puede disolver fácilmente en cloroformo.
Answer:
The DNA double helix unzips.
A strand of RNA is made from a strand of DNA.
The strand of RNA leaves the nucleus.
The strand of RNA moves to the ribosome.
A protein is produced.
Explanation:
During protein production, the messages in DNA are first encoded into mRNA in a process known as transcription. Transcription happens in the nucleus and involves an initial step of unwinding or unzipping of the double helix DNA.
Thereafter, the mRNA produced during transcription is transported from the nucleus to the cytoplasm where it gets attached to the ribosome.
In conjunction with the rRNA and the tRNA, the codons in the mRNA becomes translated into their respective amino acids. The amino acids are then linked by a polypeptide bond leading to the production of protein.
Hence, the correct sequence of event is:
<em>The DNA double helix unzips.</em>
<em>A strand of RNA is made from a strand of DNA.</em>
<em>The strand of RNA leaves the nucleus.</em>
<em>The strand of RNA moves to the ribosome.</em>
<em>A protein is produced.</em>
Answer:
A) Chromosomes are made of DNA
C) Alleles are the different forms of a gene that can exist
D) Chromosomes contain genes that control the inheritance of traits.
Explanation:
Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
Answer:
Option E, Floppy ears are dominant over straight ears; coat color is determined by incomplete dominance
Explanation:
Let the allele for floppy ears be "F" and the allele for straight ears be "f"
And Let the allele for black coat color be "B" and the color for white coat color be "b"
Now, the cross is carried out between the first group having floppy ears and white coat color (FFbb) and the second group having straight ears and black coat color (ff BB)
The 16 offspring have genotype FfBb
Phenotype of 16 offspring is Floppy ears and grey coat
Ff represents the floppy ear , thus "F" is dominant over "f"
Bb represents the grey color which is a case of incomplete dominance in which none of the real trait i.e black or white is expressed.
Hence, option E is correct
Absorptive cells- Form the walls of the intestines
epithelial cells- Form skin, body cavities, and some organs
Secretory cells- Glands (Sweat)
Nerve cells- Form the nervous system
Sensory cells- Conveys sensory information to the brain (light, smell, taste, ect.)
Muscle cells- Form muscles (body and organs)
Reproductive cells- Allow for reproduction or furthering of the species
