Answer:
1) Density
2) False
3) True
4) mass. arranged
5) graduated
6) False
7) Less, further
8)False
9) Density
Explanation:
1) Mass of atoms, size, and arrangement directly determine density of a substance.
2) Density = m/v,
3) Submerged objects must displace liquid equal to its volume because you are adding mass into a body of water
4) same as #1
5) Graduated cylinders are the most commonly used measurement tool for measuring volume
6) If it is the same substance it is equal in density. D=m/v, even if one sample is larger, both m and v increases
7) Hotter things have faster moving molecules so they are further apart. This causes the molecules to be less compact and thus less dense.
8) Liquids only float if it is less dense then the liquid it is placed on.
9) Density determins buoyancy.
Answer:
The correct answer to the question above is "PLATE COUNT TECHNIQUE"
Explanation:
DIRECT MICROSCOPIC OBSERVATION is the method of estimating the number of microorganism using microscope. Samples to be estimated are placed on microscope slides which allow few cells in a small volume to be counted. Then, the value determined is used to estimate the total number of cells mathematically. It is only difficult to aee small cells which may affect precision.
VIABLE COUNT is the estimation of the living cells in a given sample.
PLATE COUNT TECHNIQUE is used to estimate the number of viable cells that are present in a given sample of actively growing or dividing cells based on bacteria cells found on agar plate. A sample to be counted is diluted in a solution that will not kill the microorganisms, this is done to enable accurate counting as only living bacteria will be counted.
Renewable is more reliable and not a liability ther you go
Answer:
Explanation:
Only a fraction of the genes in a cell are expressed at any one time. The variety of gene expression profiles characteristic of different cell types arise because these cells have distinct sets of transcription regulators. Some regulatory proteins affect the transcription of multiple genes.
Of course the parents strand.
