Identify the steps of the lytic cycle.
The pieces made in replication are
assembled to complete the new virus
particles
The new viral nucleic acid and viral
proteins are replicated
The virus attaches to the host cell.
The original virus releases a protein that
causes the cell wall to burst (lysis), killing
the cell and releasing viruses.
The host's DNA is disassembled and the
virus takes over the cell's metabolic
activity
All the given steps are of lytic cycle.
Lytic cycle is used by a bacteriophage to reproduce inside a bacteria.Bacteriophage are the viruses.What is lytic cycle?
The lytic cycle is production of new phage progeny and death of the host bacterial cell, this is a multistep process involving precise coordination of gene transcription and physical processes.
The six stages are:

El vapor se puede transportar a través de la atmosfera. A medida que el vapor se enfría , el agua se condensa en gotitas y forman y forman nubes y da como resultado
Answer:
Precipitación.
Explicación:
El agua se mueve del cuerpo de agua a la atmósfera debido al proceso de evaporación en forma de vapor. A medida que los vapores de agua se enfrían, el agua se condensa en gotitas y forma nubes que resultan en precipitaciones en forma de lluvia y nevadas. Los vapores de agua se vuelven más pesados cuando se condensan y debido a su cuerpo pesado no pueden permanecer en la atmósfera por lo que caen a la tierra en forma de lluvia y nevadas.

Answer:
Monocots differ from dicots in four distinct structural features: leaves, stems, roots and flowers. ... Whereas monocots have one cotyledon (vein), dicots have two. This small difference at the very start of the plant's life cycle leads each plant to develop vast differences.

Experimental Scenario
Donna has observed that her father can control the speed of their grandfather clock by adjusting the
height of the weight on the end of the pendulum. Donna thinks that the pendulum will move faster
when the weight is lowered, and wants to test her idea. Donna gets a stopwatch and measures the
time it takes for the pendulum to swing twenty times when the weight is moved to its lowest position.
Donna begins to move the pendulum up by 1 cm and continues to measure the time for twenty swings
of the pendulum. Donna records her data
SCI 1.4 Investigation Plan
1) Provide a brief description of the methods that are being used to run the experiment
Answer:
Reduce the mass and measure the speed of pendulum.
Explanation:
First measure the swings of the pendulum at its original weight. After that some weight is removed from the pendulum and again measure the number of swing of pendulum at specific time period. We have to reduce mass of pendulum and then measure the number of swings. In this way, this experiment moves forward and we can find out the impact of mass on the speed of pendulum.

Explanation:
It could be that both the parents were heterozygous, meaning having a dominant and recessive allele for example Aa..after these are paired you would see that they will form a white fur offspring.

How does mining impact the enviorment
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes.
Answer:
Mine exploration, construction, operation, and maintenance may result in land-use change, and may have associated negative impacts on environments, including deforestation, erosion, contamination and alteration of soil profiles, contamination of local streams and wetlands, and an increase in noise level, dust

Humans use special body parts for functions such as breathing and breaking down food. Some living things, such as bacteria, are too small to perform these functions. True false Submit
Answer:
False
Explanation:
Bacteria do not have organs like humans. However, bacteria have specific structures to perform certain essential functions.
Among the bacteria, there are the respirators, which perform aerobic cell respiration, where oxygen gas is the final acceptor of hydrogen ions. Also, some bacteria perform anaerobic cell respiration. In those, oxygen gas is replaced by other molecules, which function as hydrogen acceptors such as nitrates or sulfates. Bacteria respiration occurs through the mitochondria.
In addition, bacteria can have different forms of "obtaining food"
Some can obtain their food through photosynthesis, degrading organic compounds. Other types of bacteria use the energy released in oxidation reactions of inorganic compounds, such as those that participate in the nitrogen cycle.
Finally, there are saprophagic bacteria, which obtain food from corpses and the remains of living beings, and the parasite ones, which find this food in the tissues of living beings, often causing them illness.

qué ventajas le trajo al ser humano el poder andar en 2 patas.
Answer:
The advantage that hominids had when they developed bipedalism is truly great. Walking on two legs instead of four allowed hominids to free up their arms. Using their arms they could now make tools, stretch trees, and use their hands for social communication. The development of bipedalism also allowed for long-distance walking and eventually endurance running. Bipedalism, basically, was a key step for hominids' "brains to grow".
[tex]{\sf{\boxed{\boxed{\tt\green{Las \: ventajas}}}}}[/tex]
La gran cantidad de ventajas que trajo el bipedalismo significó que todas las futuras especies de homínidos llevarían este rasgo. El bipedalismo permitió a los homínidos liberar completamente sus brazos, lo que les permitió hacerEnglish:
The advantages
The host of advantages bipedalism brought meant that all future hominid species would carry this trait. Bipedalism allowed hominids to free their arms completely, enabling them to make and use tools efficiently, stretch for fruit in trees and use their hands for social display and communication.#CarryOnLearning
