Answer:When the applied electric field exceeds the dielectric breakdown strength of the intervening medium, a spark is generated. In a mechanism known as dielectric breakdown, the exponentially increasing electrons and ions allow regions of the air in the gap to become electrically conductive.
An electrostatic spark causes the blast. The sudden rise in temperature that occurs as the mixture ignites causes a massive increase in gas pressure. The ensuing increase in pressure could collapse the chamber with a noisy explosion if the burning vapour were to be trapped.

What’s the use of short tandem repeat?
Answer: Ok So A short tandem repeat is a microsatellite with repeat units that are 2 to 7 base pairs in length, with the number of repeats varying among individuals, making STRs effective for human identification purposes.STRs are extremely useful in applications such as the construction of genetic maps (49), gene location, genetic linkage analysis, identification of individuals, paternity testing, as well as disease diagnosis 50., 51.. STR analysis has also been employed in population genetics.

The modern cell theory doesn't say
A all living things are multicellular
B cells are the smallest living unit in all organisms
C all cells come from other cells
D all living things are made of cells
Answer:
A
Explanation:
Modern cell theory states: cells are the basic unit of structure and function for all living things, all cells come from preexisting cells, and all living things are made from cells. It does not state that all living things are multicellular, in fact there are plenty of unicellular organisms. Therefore the answer is A.

The juvenile salmon utilize special structures to alter their behavior.
The juvenile salmon alter their behavior but do not utilize special structures.
Answer:
due to the salmons body and biology the salinity doesnt matter because they can change whats around them using the salt from inside their body
Explanation:
they both utilize and alter behavior
The populations of juvenile salmon respond to changes in salinity as they migrate the juvenile salmon utilize special structures to alter their behavior. Therefore, option C is correct.
What is salinity ?The amount of dissolved salt in a body of water is known as salinity. It makes a significant contribution to conductivity and influences many aspects of the chemistry of natural waters as well as the biological activities that take place there.
In soils and seas, primary salinity is a natural occurrence. Salt lakes, salt pans, salt marshes, and salt flats are a few examples of naturally occurring salty landscapes. Salting caused by human activity, typically land development and agriculture, is known as secondary salinity.
Salinity is the buildup of salt to a degree that harms the built environment and the ecosystem in general. While there are many areas of the Australian terrain that are naturally salty, human activity has the potential to raise salt levels. Water and salinity go hand in hand.
Thus, option C is correct.

Provide an explanation for why the indigo dye did not adhere to the different fibers in your test fabric. You will need to do a little bit of outside research on what chemicals make up some of the fibers. You may also need to do some research on intermolecular forces and why some interactions are stronger than others. Please make your explanation at least 500 words in two or more paragraphs. At least one in-text citation is required along with a list of your source(s) in your preferred citation style (MLA, APA, ACS, Chicago Style, etc.).
Answer:
Due to lack of bonds.
Explanation:
The indigo dye did not adhere to the different fibers because the indigo dye did not make bonds with the fiber, it only attached to it physically for temporary period of time. The reduced state is also necessary for indigo because indigo cannot dissolve in water, but when it is reduced it can soluble and able to get inside a fiber to make physical bond with the fiber. Some interactions are stronger than others because of the presence of strong bond between the two different materials so strong bonding makes the materials to attach with each other for a long period of time or permanently.

Union of haploid and diploid gamete results in a zygote that is
Answer:
Triploid
Explanation:
The process whereby gametes produced by different sexes of the same species of organism come together is called FERTILIZATION. A gamete is said to be HAPLOID (n) if it contains one set of chromosomes while it is DIPLOID (2n) if it contains two sets of chromosomes.
Hence, if an haploid (n) and diploid (2n) gamete unites, a zygote that is TRIPLOID (3n) emerges or forms. A triploid zygote will have three sets of chromosomes i.e. n + 2n = 3n.

To better comprehend how the human body's components interact with one another and work together as a whole, scientists divide the body into systems. A group of bodily parts that cooperate to carry out a specific task is known as a body system.
For instance, the integumentary system, that shields the body from its surroundings, is made up of the skin, hair, and nails. Another instance of an organ that guards the body is the immune system.

What do you observe about the structure
of the white blood cell? How do you think
this is related to its function of trapping
pathogens in the body?
Please help I’ll give brainlyiest
Answer:
White blood cells engulf and digest pathogens and any other unknown material in the blood and tissues. They engulf the pathogen into a vesicle called a phagosome. This fuses with a lysosome and the enzymes break down the pathogen.
White blood cells foremostly recognize any pathogen or foreign substance in the body and then engulf it with the help of receptors like Toll-like receptors. Finally, the killing of antigen takes place by phagocytosis.
What do you mean by Pathogens?Pathogens may be defined as any microorganisms which are capable of inducing diseases in other living organisms.
After engulfing, the antigen is packed under a vesicle known as a phagosome. This phagosome is then treated with lysosomes to form a structure known as phagolysosomes.
Thes phagolysosomes are responsible for the breakdown of antigen, which is then presented by MHC molecules to perform perforin-granzyme mediated killing of antigen.
Therefore, it is well described above.
