Explanation:
when preparing pure cultures, dilution is necessary for
Dilution is necessary during pure culture preparation to reduce the bacterial load and allow readable colonies to grow.
Dilution of bacteria culture is carried out in comparison to McCfarlan standard so as to have a decent number of bacteria that will not be too numerous or too little to observe the growth of distinct colonies during culture preparation.
Without dilution, colonies may form but may be too numerous to count. Too much dilution may also lead to no growth in the culture plates.

how many chromosomes would be found in an allopolyploid plant if its parents had diploid numbers of 2 and 10, respectively?
Answer:
6
Explanation:
The allopolyploid off spring should have 6 chromosome the gametes produced for the diploid number 2 should be 1 and for 10 it should be 5 (n/2) the two gametesof both parents gametes should then fuse ( 1+5 ) giving us 6
or
gamete chromosomes =n÷2
gametes for diploid number 2
N= 2
2÷2 = I
gamete Chromosome = 1
gamete for diploid number 10
N=10
10÷2 =5
Allopolyploid= 5+1
=6
1. How do fossils form?
Explanation:
There is a LOOOONG process for this so here it is;
First things first.The animal dies. Soft parts of the animal's body, including skin and muscles, start to rot away. Scavengers may come and eat some of the remains. Before the body disappears completely, it is buried by sediment - usually mud, sand or silt. Often at this point only the bones and teeth remain. Many more layers of sediment build up on top. This puts a lot of weight and pressure onto the layers below, squashing them. Eventually, they turn into sedimentary rock. While this is happening, water seeps into the bones and teeth, turning them to stone as it leaves behind minerals. This process can take thousands or even millions of years.

Students were given a list of seven elements and asked to identify the four elements that are most abundant in biomolecules. Which table correctly identifies the four most-abundant elements in biomolecules?.
Answer:
Carbon, hydrogen, nitrogen, oxygen
Explanation:
Not sure what the tables are?
Biomolecules are important for living organisms and vital for cell structure and functioning. The cells are made up of biomolecules as their structural organization.
The four most abundant biomolecules are:
Carbon, Oxygen, Nitrogen and Hydrogen
The biomolecules can be explained as:
The central biomolecules for life activities are these elements that contribute to major processes.The main building blocks like carbohydrate is composed of carbon, oxygen and hydrogen. They provide energy to the body by breaking into small molecules.Proteins are vital for cell signalling and transport. They are composed of amino groups consisting of nitrogen.Therefore, carbon, nitrogen, hydrogen and oxygen are the most abundant biomolecules.

Circle one: KE / GPE / both
Show your work for finding the values of each type of energy the object has:
Answer: Both
Explanation:
KE can be solve using the formula:
ke = 0.5 mv^2
where m is the mass of the object
v is the velocity
ke = 0.5 ( 2 kg ) ( 5 m/s)^2
ke = 25 J
the GPE can be solved using the formula:
GPE = mgh
where m is the mass
g is the acceleration due to gravity ( 9.81 m/s^2)
h is the height
GPE = ( 4 kg)(9.81 m/s^2)( 40 m)
GPE = 392.4 J

what solution, (hypertonic, hypotonic, isotonic) would make osmosis go faster?
Answer:
Explanation:
Osmosis is the movement of WATER molecules across a semipermeable membrane (such as the cell membrane) from where there is a high concentration of water to where there is a low concentration of water. The interior of a living cell consists of cytoplasm, which is a solution of mostly water with dissolved substances such as salt.
Now for the fun stuff! An Isotonic solution is a solution that has the same concentration of dissolved substances as is found inside the cell. If a cell is surrounded by isotonic solution, then there is no net movement of water across the membrane by osmosis, because the concentration of water is the same on both sides of the membrane.
A hypertonic solution is a solution with a higher concentration of dissolved substances than is found inside the cell. If a cell is surrounded by hypertonic solution, then water will move OUT of the cell by osmosis because there is a higher concentration of water inside the cell compared to outside (where there is lots of dissolved salt, etc.) A cell in hypertonic solution will shrink.
A hypotonic solution is a solution with a lower concentration of dissolved substances than is found inside the cell. If a cell is surrounded by hypotonic solution, then water will move INTO the cell by osmosis because there is a higher concentration of water outside the cell compared to inside. A cell in hypotonic solution will swell up and, if there is no cell wall, may burst. A silly but simple way to remember that water moves into a cell in hypotonic solution is that "hypo causes the cell to swell up like a hippo"

how long after conception can you get a positive pregnancy test
Answer: Although many tests indicate you can test as soon as five days before your next period, the most accurate results will be obtained after you have missed your period and the earliest a test can provide an accurate reading is 14 days after conception. Tests differ in sensitivity in detecting HCG in the urine.
Explanation:

Answer:
B. Life forms have a common evolutionary ancestry.
Explanation:
A. All organisms evolved from separate original ancestors.
-> We know this is not true. If organisms evolved from separate ancestors, they would have different genetic code.
C. Protein makes up the genetic material.
-> This was proven false in Hershey–Chase experiment.
D. Evolution does not really occur.
->This one's obviously false as speciation happens regularly.
