Answer:

Sandstone does not react with Hydrochloric acid. The acid soaks into the rock because the rock is porous, filled with tiny holes. It is made up of tiny grains of sand cemented together by intense pressure.

Given that a virus divides every 3 hours, and that a cell lyses (explodes) after it reaches a viral load of 5,000,000 units, how
vladimir2022 [97]

The replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

<h3>How to calculate the Exponential growth/decay formula?</h3>

x ( t ) = x 0 × (1 + r ) t

  • x(t) is the value at time t.

  • x 0 is the initial value at time t = 0.

  • r is the growth rate when r/ 0 or decay rate when r < 0, in percentage.

  • t is the time in discrete intervals and selected time units.

Whit this information, we can conclude that the replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

salantis [7]

Answer:

el enunciado hace referencia a estructuras análogas

Explanation:

La estructuras análogas (por ejemplo, órganos, tejidos, etc) son aquellas que cumplen la misma o similares funciones pero que poseen un origen evolutivo distinto (es decir, no comparten un antepasado común) y son producto de la convergencia evolutiva. Por el contrario, estructuras homólogas son aquellas que se caracterizan por tener un origen evolutivo común (comparten un antepasado común), independientemente de la función que cumplan. Las estructuras análogas se caracterizan por tener diferentes orígenes embrionarios y planes de construcción distintos (es decir, las células que dan origen a este tipo de estructuras son de linajes diferentes). Un ejemplo bien conocido de estructuras análogas son las alas de mariposas y murciélagos, las cuales cumplen la misma función pero no derivan de un antepasado común.
