Explanation:
OK, first of all, let me explain to you, what is a scientific theory...
A scientific theory is an explanation and demonstration of an aspect that exists in the natural world or universe that has been verified by the scientific way through repeated testing of the experiment with accepted protocols of observation, measurements and evaluation of results.
A scientific law is generated in the same procedure as above, but it can predict a wide range of natural phenomena.
Ex-: you are throwing a basketball from the top of a dam to the river. according to physics on earth, it should fall down. it's a law. no matter where you are, that basketball touches down the ground if there's any gravitational force.
But cell theory cannot be assumed to be common throughout the entire universe. Because we may find some other form of life that has some other plans. viruses are not obeying this theory.
*In a nutshell, a law is stable from its' origin. most of the time, it won't change. but theories will change with updating facts of science.

Describe the Lysogenic cycle.
No dam links
Answer:
Here ya go
Explanation:
The lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm. In some interactions between lysogenic phages and bacteria, the lysogenic conversion may occur, which can also be called phage conversion.

A 35-year-old woman comes to her dentist complaining of tenderness and pain in her cheek near the parotid gland, as well as bad breath and a foul-tasting mouth at meal times. A radiopaque fluid is injected into the parotid duct system through cannulation, and this sialography of the parotid duct confirms blockage by a calculus (sialolith). What muscle, through which the parotid duct passes, is most likely causing the stenosis where the sialolith now resides, blocking the drainage of the parotid duct

Explanation:
A black chicken and a white chicken are crossed. What is the probability that they will have erminette chicks?
Answer:
[tex]Probability = 100\%[/tex]
Explanation:
Given
Crossing of a black chicken and a white chicken
Required
The probability of having erminette chicks
The genotype of a black chicken is represented as: BB
The genotype of a white chicken is represented as: WW
The genotype of an erminette chicken is represented as: BW
Using a Punnett square, we have:
[tex]\begin{array}{ccc}{} & {B} & {B} & {W} & {BW} & {BW} & {W} & {BW} & {BW}\ \end{array}[/tex]
The result of crossing the two chicken gives 4 BW out of a total of 4
i.e 4 erminette chickens out of 4 possible chickens
So, the probability is:
[tex]Probability = \frac{4}{4}[/tex]
[tex]Probability = 1[/tex]
Represent as percentage:
[tex]Probability = 100\%[/tex]
When identifying the agent responsible for causing a disease, why is evaluation of colony morphology not enough?
Answer:
Some infectious diseases are distinctive enough to be identified clinically. ... Infections may be caused by bacteria, viruses, fungi, and parasites. ... Microbial Identification: Colony and cellular morphology may permit preliminary ... Diagnostic medical microbiology is the discipline that identifies etiologic agents of disease.
Explanation:
Microorganisms have antigens present on their surface, Antigen tests detect the presence of a microorganism directly so that doctors can diagnose an infection quickly, without waiting for a person to produce antibodies in response to the microorganism.
Evaluation of colony morphology is not enough as it is not a definitive test. colonies of different bacteria can look the same, so it can help narrow.
What is antigen tests?An antigen test is an immunoassays test used for the detection of a specific viral antigen that indicates current viral infections.
Hence, Antigen tests detect the presence of a microorganism whereas, Evaluation of colony morphology is not enough as it is not a definitive test.

using the graph, the temperature seasonal force from the other Forest biomes. choose all the apply
A) the temperature seasonal Forest averages 100 to 200 cm rainfall/year
B) the temperature seasonal Forest is cooler and wetter than the tropical rainforest
C) the temperature seasonal Forest has warmer average temperatures than the Boreal forest
D) the temperature seasonal rainforest has similar temperatures but less rain than the temperate rainfores
E) the temperature seasonal rainforest has similar rainfall to the Boreal and tropical seasonal rainforest, but is much warmer than either one
Answer:
The correct answer is - A and C,
Explanation:
According to the graph, the following conditions are matched correctly with the temperature seasonal forest with other biomes:
The temperature seasonal forest has the precipitation range from 50 cm to 250 cm rainfall per year approximately. The average rainfall from this would be 150 cm/year or between 100 to 200 cm per year.
B. the temperature seasonal forest has a temperature between 15 degrees Celsius to 20 degrees celsius which is warmer than the boreal forest that has a temperature between 0 to 15 degrees Celsius approximately.

Which statement best describes how cell theory relates to a stem cell's ability to
change into specialized cell types?
The stem cells have the unique ability to undergo cellular differentiation which results into formation of a more specialized cell type which performs a unique function in body. Such as blood cells, neurons, etc.
What is Cell theory?
Cell theory has been proposed which describes various properties of a cell and how these cells develop. The theory has given some postulates and one of these postulates is that the new cells originate from pre-existing cells. Thus, the cell theory explains that the specialized cells which are present in body are synthesized from the stem cells.
Under the favorable conditions, the stem cells divide to form specialized daughter cells. These daughter cells become either a new stem cell or the specialized cells with a more specific function which includes blood cells, neurons, muscle cells or bone cells.

what type of destruction result in primary succession
Answer:
Destruction that ends with the creation of new land, like a volcanic eruption
Explanation:
Primary succession refers to how life comes to be in a new land that has never been inhabited before. So any type of destruction that creates land that has never supported life would cause primary succession. Volcanic eruptions is the most common type of destruction for primary succession because the lava cools and becomes new land. Primary succession is defined by succession occurring in an area that does not have any soil for life to grow on.
