Answer: They study Microoganisms

Explanation:

They study micro (meaning small) organisms, for example, bacteria and algae, which is extremely minature. It is difficult and dangerous if left infected, but their work is sucessful if worked with the right tools, they try to understand how microorganisms live in their small environment

in 6-8 sentences, explain how stream volume and speed affect the size, shape and flow of streams and rivers.

sukhopar [10]

Explanation:

The higher the volume of water in a stream, the higher its speed and the wide its size and shape which ensures a proportionate flow rate.

To quantify how the speed of stream, we use the quantity, discharge in hydrology;

Discharge is the volumetric rate of water flow past a point at a particular time.

Discharge = $\frac{volume of water}{time}$

We see that discharge is directly proportional to the volume of water in a stream.
It is inversely proportional to the time taken.
We know that volume is the amount of space occupied by a body. It is function of its size and shape.
A big water body that is deeper, wider and longer will have more wate and a greater discharge.

The testcross makes it possible to determine the genotype of an individual of unknown genotype who exhibits the dominant version

klio [65]

Answer:

All of the above answer choices are correct.

Explanation:

Test cross is done to find out the genotype of an individual displaying dominant phenotype as it can be homozygous or heterozygous. To find this the individual is crossed with a recessive phenotype individual. For example: a dominant trait tall height can be homozygous TT or heterozygous Tt. If it is TT all the offspring of test cross with tt will be tall. If it is Tt half of the offspring will be tall and half of the offspring will be short.

Multiple offspring are required to come to the final result because offspring production happens in random order and it might take a few tries before another type of phenotype is produced. For example: If a test cross produces an individual with dominant phenotype we can still not surely say if the test individual is homozygous or heterozygous because both can produce dominant phenotype in test cross. We need more offspring to check if the recessive phenotype is produced or not and accordingly decide the genotype of test individual.

Hence all of the above answer choices are correct.

What is the pH if 20 mL of pH = 2 solution is diluted to a final volume of 600 mL?

Mashutka [201]

Explanation:

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge. pH measures how basic or acidic a water-based solutions are, with a formula for pH is

pH = -log[H+].

...where pH is -base 10 log of the concentration of hydrogen ions within the solution.

Initial volume= 20 mL

Final volume= 600 mL

# of dilutions= $\frac{600}{20}$ = 30

for a pH 2= [H+]= $10^{=2}$

∴ [H+]= $\frac{10^{-2}}{30} = 3.333 * 10^{-4}$

and pH is an antilog of [H+]= - log $\frac{10^{-2}}{30} = 3.333 * 10^{-4}$

∴pH = 3.47
