<em>Answer: The bases are the "letters" that spell out the genetic code. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.</em>
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.
Answer:
Because the Southern Hemisphere has more ocean and much less land. As you may know water heats up and cools down more slowly than land.
Plant essential oils (EOs) and their compounds have proven in vitro efficacy as antimicrobial, antioxidant, immunodulating and anti-inflammatory agents. These substances deserve an important place as feed additives that are generally considered as safe. The available in vivo data show that EOs could find use as natural growth promoters in animal diets. However, the available evidence on the possible positive effects of these substances on nutrient digestibility and the function of the gut is rather limited. Also, the benefits of EOs’ applications in animal’s diets depend on diverse parameters. These parameters can be, on the one hand, the unstable composition and the different levels of addition in the diet, and on the other hand, variable animal genetic factors. A better understanding of the gastrointestinal tract microflora composition and activity is needed in order to maximize the use of EOs and to manufacture effective products. Essential oils could find application in cases where approved drugs or chemical substances are unwanted, for example, biological farming. Hope this helps! Mark brainly please!
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
<em> B. Master genes do not </em><u><em>determine the organization of the genome</em></u><em>
.</em>
<em> C. </em><u><em>Regulation of cell metabolism</em></u><em> depends of substances as hormones and enzymes.
</em>
<em> D. </em><u><em>The rate of translation</em></u><em> does not depend on the activity of master genes.</em>
