Answer:
La falta de células cono en la retina
Explanation:
En vertebrados, la retina se encuentra formada por dos tipos básicos de células denominados células conos y células bastones. Las células cono son unas células fotosensibles las cuales forman una capa concentrada en el centro de la retina. Estas células (células cono) son responsables de la distinción entre diferentes colores del espectro de luz visible. Las células cono se clasifican en tres tipos de acuerdo a su sensibilidad para distinguir la luz azul, roja, y verde. Esta sensibilidad se debe a la presencia de diferentes tipos de proteínas opsinas, las cuales confieren la capacidad de absorber la luz en una longitud de onda particular: cianopsina (sensible a la luz azul), eritropsina (sensible a la luz roja) y cloropsina (sensible a la luz verde). Animales como los gatos y los perros son daltónicos, es decir, no pueden completamente diferenciar los colores, debido a la falta de una o más clases de células cono (y por lo tanto también de opsinas) en la retina.

Transformation is a process in which bacteria take up new DNA released by dead cells and integrate it into their own genomes (see Chapter 9). In Streptococcus pneumoniae (which causes many cases of pneumonia, inner-ear infections, and meningitis), the ability to carry out transformation requires from 105 to 124 genes, collectively termed the com regulon. The com regulon is activated in response to a protein called competence-stimulating peptide (CSP), which is produced by the bacteria and exported into the surrounding medium. When enough CSP accumulates, it attaches to a receptor on the bacterial cell membrane, which then activates a regulator protein that stimulates the transcription of genes within the com regulon and sets in motion a series of reactions that ultimately result in transformation. Does the com regulon in S. pneumoniae exhibit positive or negative control
Answer:
Positive (inducible)
Explanation:
Increased levels of CSP induce the receptor to stimulate transcriptional activator functions, which allow gene expression to occur similar to what happens in positive inducible.
Explain why the pulse rate taken at the wrist could actually be lower than if you listened to the heart rate with a stethoscope right over the heart.
Answer:
under
Explanation:
To accurately test for a slow heart rate, a person must measure their resting heart rate. To achieve this, they must avoid checking the pulse shortly after exercising or waking up.
To check the pulseTrusted Source, a person should sit in a comfortable and relaxed position and feel for the pulse at the wrist. If unable to locate the pulse at the wrist, they should try feeling for the pulse on the side of their neck.
To work out their heart rate, the person counts heartbeats for 10 seconds, then multiplies the number by six. For a more accurate pulse, the person can count the number of beats for a full minute. This figure is the resting pulse.
If the number is lower than 60, a person has bradycardia.

Speciation, causing an increase or decrease in competition among different species
Habitat fragmentation, due to the construction of new housing complexes
Pollution from factories, causing increasing atmospheric carbon dioxide
Answer: B speciation causing an increase or decrease in competition among different species.
The other choices are the HIPPCO or the human impacts that cause extinction not geographical changes
The geological changes that impact the dynamics of an ecosystem Speciation, drive an increase or decrease in contest among different species.
What is the process of speciation?Speciation is the process by which new species form. It happens when groups in a species become reproductive remote and branch.
In allopatric speciation, sets from an established population grow into various species due to years of geographical separation.
Thus, option "B" is correct, Speciation is how a new type of plant or animal species is created.

What would occur to the amino acid sequence if the following mutation (G --> C in bold below) were to take place?
DNA sequence 3' TAC GGG ACT CTT TCC ACT 5'
What type of mutation is this?
Explanation:
TAC GGG AGT CTT TCC ACT -DNA
AUG CCC UCA GAA AGG UGA -mRNA
Met Pro Ser Glu Arg Stop -Amino acid sequence
Can't see the bold :/
Insertion mutation I believe.
A codon chart can be used to read the genetic code. To utilize this chart, start by finding the first codon nucleotide, then the second, and finally the third. The chart will then show which codon codes for the amino acid. Because the genetic code is degenerate, there are several codons for each amino acid.
What role of genetic code in DNA sequence?The genetic code serves as the body's language for converting the DNA instructions from our genes into the constituent parts of life. It is typically discussed using the “codons” found in mRNA since mRNA is the messenger that transmits information from the DNA to the site of protein production.
Therefore, TAC GGG AGT CTT TCC ACT -DNA
AUG CCC UCA GAA AGG UGA -mRNA
Met Pro Ser Glu Arg Stop -Amino acid sequence

Clasisifcar los huesos del esqueleto apendicular y axial en : largos, cortos, planos, irregulares, sesamoideos. ayudaaa por favor!!
Answer: Se clasifican de acuerdo a la forma y tamaño.
Explanation:
El esqueleto posee distintas funciones como el soporte del cuerpo en sí y la protección de órganos vitales. Para lograr esto, existen distintos tipo de huesos con distintas formas, de acuerdo a su ubicación y función.
Los huesos del esqueleto humano se dividen en dos grandes grupos:
Esqueleto apendicular: Huesos que forman los miembros superiores e inferiores, además de la cintura escapular y la pelviana. El esqueleto axial: Huesos del eje largo del cuerpo en la cabeza, columna y caja torácica.Tanto en el esqueleto apendicular como en el axial, existen cinco tipos de huesos: largos, cortos, planos, irregulares, sesamoideos.
Largos: Se clasifican así por ser mas largos que anchos y su función es la de soportar el peso del cuerpo y producir movimiento. Se ubican principalmente en el esqueleto apendicular como por ejemplo, huesos del miembro inferior como el fémur, tibia y peroné de las piernas. Además de los huesos en los miembros superiores como radio, húmero, cúbito en los brazos; y falanges metacarpianos en las manos.Cortos: Se clasifican así por tener aproximadamente la misma longitud que ancho, y su función es proporcionar estabilidad y movimiento. Estos huesos se ubican en articulaciones del tobillo y muñeca. y algunos ejemplos son los huesos tarsianos en tobillos (navicular, cuboides, astrálago, calcáneo, cuneifrome lateral, intermedio y medial); y los huesos carpianos de la muñeca (piramidal, pisiforme, trapezoide, trapecio, escafoides, hueso ganchoso, hueso semilunar, hueso grande)Planos: Son huesos de forma plana y su tamaño de área grande sirve para la unión de distintos músculos. Su función principal es la de la protección de órganos internos. Entonces, se encuentran en la caja torácica (donde se encuentran por ejemplo las costillas y esternón), y en la pelvis (donde se encuentra el ilion, isquion y pubis). También forman parte de la estructura ósea de la cabeza, donde se hallan los huesos occipital, frontal, parietal, lagrimal, nasal y vómer.Irregulares: Su forma y estructura es variable además de que pueden tener forma compleja. Su función es la de proteger órganos internos, por ejemplo a la médula espinal que es protegida por las vértebras y huesos irregulares de la columna vertebral .Sesamoideos: Huesos redondos en tendones donde los protegen del deterioro, particularmente en los tendones de las manos, pies y rodillas, como por ejemplo la rótula. hold your hand in front of your face.
