Why is it necessary to check total aerobic microorganisms in microbiological quality control but not to test total anaerobic microorganisms?
Answer:
While many microbes are harmless to humans, others can cause serious problems. They can spoil food, introduce toxins, cause disease and lead to a host of other problems. The importance of microbiological testing is to quickly identify these contaminants and treat them before they do irreversible damage.
Explanation:
Aerobic bacteria are bacteria that can grow and live when oxygen is present.

what is adaptation give any four characters of aquatic plants
Explanation:
Animals have special features that help them to live in a particular place. Therefore this features is called adaptation.
1] Aquatic plants have leaves that float on the surface of water.
2] Thier leaves are rarely have stomata.
3] Thier leaves can perform all the work without xylem.
4] They are usually lack cuticle layer in order to avoid excessive dryness.
Answer:
The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water.
Four characters of aquatic plants are as given below:
1) most aquatic plants donot need culticles or have thin culticles as cuticles prevent loss of water.
2) aquatic plants keep their stomata always open for they do not need to retain water.
3) on each side of their leaves are a number of stomata.
4) aquatic plants have less rigid structure since water pressure supports them.

An ecologist counted the number of eggs in randomly selected nests in a population of birds. To test the hypothesis that the number of eggs per nest follows a Poisson distribution at the 5% level of significance, you will need to compare a calculated value with a critical value.
Eggs Number of nests Prob Expected
nest, xi per fi
0 15 0.2845 19.9
1 29 0.3576 25.0
2 19 0.2248 15.7
23 7 0.1331 9.3
SUM: 70 1.0000 70.0
What are the calculated and critical values for this test?
a. calculated = 45.6; critical = 5.991.
b. calculated = 3.10; critical = 5.991.
c. calculated = 5.89; critical = 5.991.
d. calculated = 3.10; critical = 7.815.
Answer:
d. calculated = 3.10; critical = 7.815.
Explanation:
To test the hypothesis Given in the question above, we use the Chisquare goodness of fit :
The test statistic is defined as :
χ² = Σ(Observed - Expected)² / Expected
Observed = number of nests
χ² = ((15 - 19.9)^2 / 19.9) + ((29 - 25)^2 / 25) + ((19 - 15.7)^2 / 15.7) + ((7 - 9.3)^2 / 9.3)
χ² = 3.1089
The critical value :
df = n - 1 = 4 - 1 = 3
The critical value ;P(χ² at 0.05, df = 3 ) = 7.815

Why did the White House experience water damage ?
1.
It is made of granite which is strong.
2. It is made of sandstone which is very porous and is easily penetrated by rainwater
3. It is made of non-porous sedimentary rock
The White House building is made of sandstone which is very porous as a result water is easily penetrated inside it which causes damage and make the walls of building weak.
The White House is made of gray-colored sandstone that is brought from quarry in Aquia, Virginia. The north and south porticos of white house building are constructed with red Seneca sandstone brought from Maryland. These sandstones are porous in which rainwater is easily penetrated in it that cause damage to the white house building so it is concluded that the building is made of porous sandstone.

what evidence shows that biological molecules on earth form naturally?
Explanation:
La siguiente entrada tiene como objetivo realizar una breve explicación sobre las moléculas biológicas lipídos y carbohidratos, las cuales son muy diversas ya que están formadas por carbono, lo cual hace que puedan formar muchos tipos de enlaces. Esta capacidad permite que las moléculas orgánicas adopten muchas formas complejas, como son las cadenas, las ramificaciones y los anillos.
Las moléculas biológicas son grandes polímeros que sintetizas para poder enlazarse con otras subunidades mucho mas pequeñas conocidos como monómeros. Las cadenas de subunidades estan unidas por enlaces covalentes los cuales se forman por deshidratación, estas cadenas pueden romperse por hidrólisis. La moléculas biologicas más importantes son los carbohidratos, lípidos, proteínas y ácidos nucleicos.

The development of an organ system like a vascular system over a long period of time in plants is an example of evolution. Thus option A is correct.
What is evolution?Evolution is a series of events that have taken place in several years to make the species more advanced for the environment due to the introduction of multiple mutations in the genetic sequence.
During evolution, plants have gained the genetic mutation that codes for the vascular system which provide support and transports water in plants. So option A is correct.
