Hello There!
Before viruses can reproduce, they must infect a host cell.
Viruses need a way to enter the body before they can infect a host cell.
Answer:
Verdadero
Explanation:
Sabemos que los caracteres dependen de los genes. Y los genes pueden presentarse en forma de alelos dominantes, o alelos recesivos. La expresión de los alelos recesivos son enmascarados o escondidos por el alelo dominante. Es decir, que si ambos alelos se encuentran juntos en un heterocigota, solo el alelo dominante se expresará.
Entonces el alelo dominante expresa la característica que resulta dominante, mientras que el alelo recesivo expresa la característica recesiva.
Genotipo:
- Homocigota dominante ----> Expresa caracter dominante (Solo el alelo dominante esta presente)
- Heterocigota -------------------> Expresa el caracter dominante (Ambos alelos estan presentes, pero el dominante es quien se expresa)
- Homocigota recesivo --------> Expresa el caracter recesivo (solo alelos recesivos estan presentes)
Por ejemplo, si tenemos dos fenotipos rojo y amarillo, y sabemos que el color esta codificado por un gen dialelico llamado M. También supongamos que no sabemos qué alelo expresa qué color. Teniendo solo estos datos, no podemos decir si el rojo es el color dominante o si el amarillo lo es.
Sin embargo, si tenemos los siguientes genotipos acompañando esta información:
- MM--> Amarillo
- Mm--> Amarillo
- mm --> Rojo
Recién ahora podemos deducir que el caracter dominante es el amarillo.

Warmth, moisture, pH levels and oxygen levels are the four big physical and chemical factors influencing microbial growth. In most buildings, warmth and moisture are the most significant overall issues current
<h3>How the bacterial growth curve relates to what happens to the bacterial population?</h3>
The bacterial growth curve symbolizes the number of live cells in a bacterial population over a period of time. There are four different phases of the growth curve: lag, exponential (log), stationary, and death. The initial phase is the lag phase where bacteria are metabolically functional but not dividing.
<h3>What are 4 states of bacterial growth?</h3>
Bacteria can live in more burning and colder temperatures than humans, but they do best in a warm, moist, protein-rich atmosphere that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria flourish in extreme heat or cold, while others can stay under highly acidic or extremely salty conditions.
