Answer:

1. El corazón se localiza en el mediastino, que es el espacio comprendido entre ambos pulmones. 2. El  miocardio es la capa funcional del corazón, puesto que su contracción impulsa la sangre hacia los pulmones y los demás tejidos. 3. Internamente el corazón presenta 4 cavidades: 2 cavidades superiores llamadas auriculasy dos cavidades inferiores conocidas como ventriculos . 4. Entre la aurícula y ventrículo del mismo lado se encuentran las válvulas auriculoventriculares. En el lado derecho tenemos la válvula tricuspide, mientras que en el lado izquierdo se encuentra la válvula mitral . 5. El ciclo cardiaco comprende dos fases, una de contracción o sistole y una de relajación llamada diastole.

Explanation:

El corazon es un organo con un tejido muscular liso especializado donde estas celulas musculares presentan uniones desmosomales de amplia conexion para la diseminacion rapida de señales, es asi como se producen contracciones ritmicas, autonomas y de manera simultanea.

El corazon a su vez presenta su auto irrigacion propia por medio de las arterias coronarias que se encargan de mantener el miocardo en buen estado de vitalidad.

A yellow female Labrador retriever was mated with a brown male. Half of the puppies were brown, and half were yellow. Explain ho
Over [174]

Answer:

The first male was bb Ee, and the second male was bb EE.

Explanation:

In Labradors coat colour is controlled by two genes. Suppose the two genes are B and E. B produces black colour and recessive form bb gives brown colour. Gene E is epistatic over gene B in its recessive form which means that ee will produce yellow colour regardless of the genotype present of B gene.

The first case is possible if the female lab is bbee (yellow) and the male lab is bbEe (brown):

bbee X bbEe

        bE      be

be  bbEe    bbee

So half of the offspring will be brown (bbEe) and half of them will be yellow (bbee)

The second case is possible if the same female bbee mates with a brown male of different genotype which can be bbEE:

bbee X bbEE

         bE

be   bbEe

So all offspring will be brown (bbEe)

Hence, the first male was bbEe and the second male was bbEE.

Match each field of study to the correct piece of evidence. Tiles molecular biology comparative anatomy developmental biology Pa
PilotLPTM [1.2K]
Molecular Biology
This field of study deals with everything related to macromolecules, thus, what you will need for molecular biology would be something you could get proteins and nucleic acids from. Among the choices, the DNA of a pig and a calf would be the most helpful.

Comparative Anatomy
Comparative anatomy is a field of study that focuses on any similarities or differences between the anatomy or structure of different animals or species in general. Among the options, having the limb structure of a pig and a calf would allow you to practice the field since you have a structure to compare.

Developmental Biology
In this field, your concern would be how species grow and develop. For you to properly observe the growth and development, you must have the embryo of a pig and a calf. Therefore, among the options, this is the correct piece of evidence for this field.

IN SUMMARY:
Molecular Biology - Both DNA of a pig and a calf
Comparative Anatomy - Both limb structure of a pig and a calf
Developmental Biology - Embryo of a pig and a calf
