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.

Calculate how long it will take for one full base pair mutation to occur. Explain your reasoning with by constructing a mathemat
scoray [572]

Answer:

Since the gene mutates at a rate of 0.76 base pairs every 17.1 million years, to find out the time it would take for 1 base pair to mutate can be calculated by dividing 17.1 million years by 0.76

17,100,000 ÷ 0.76 = 22.5 million years

The following equation can be used to describe this:

μ = [(r2/N2) − (r1/N1)] × ln (N2/N1) = (f1 − f2) × ln (N2/N1)

r1 = the observed number of mutants at time point 1

r2 = the observed number of mutants at the next time point

N1 and N2 are the numbers of cells at time points 1 and 2

Hope that answers the question, have a great day!

Which means of particle transport is shown in Figure 7–4 above?
sattari [20]
The correct option is D.
When it comes to movement of particles in an out of cells, there are two basic types of transportation, these are passive and active transportation. The passive transportation of particles does not require  the use of energy while the active transport system requires the use of energy in the form of ATP. From the diagram given in the question, it can be seen that energy is involved in the process. Energy is mainly needed to move the particles against the concentration gradient since the inside of the cell is highly concentrated while the outside has low concentration. <span />
