Importance of antimicrobial emulsion​

Answers

Answer:

Citral is a typical essential oil used in the food, cosmetic, and drug industries and has shown antimicrobial activity against microorganisms. Citral is unstable and hydrophobic under normal storage conditions, so it can easily lose its bactericide activity. Nanoemulsion technology is an excellent way to hydrophilize, microencapsulate, and protect this compound. In our studies, we used a mixed surfactant to form citral-in-water nanoemulsions, and attempted to optimize the formula for preparing nanoemulsions. Citral-in-water nanoemulsions formed at So 0.4 to 0.6 and ultrasonic power of 18 W for 120 seconds resulted in a droplet size of < 100 nm for nanoemulsions. The observed antimicrobial activities were significantly affected by the formulation of the nanoemulsions. The observed relationship between the formulation and activity can lead to the rational design of nanoemulsion-based delivery systems for essential oils, based on the desired function of antimicrobials in the food, cosmetics, and agrochemical industries.

All of the following statements about ferns are correct except the gametophyte is a conspicuous generation. Therefore, the correct option is D.

In ferns the gametophyte is usually much smaller and less noticeable, whereas the sporophyte is the more noticeable generation. The sporophyte, the famous giant pearl fern plant, is a major stage in the fern life cycle. Gametes (eggs and sperm) are produced by the gametophyte, which is a small, autonomous stage responsible for sexual reproduction.

Answers

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.

Answers

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

Lest we think that slavery existed in fact before it did in law, Oscar and Mary Handlin assure us that the status of Black people down to the 1660's was that of servants. A critique of the Handlins' interpretation of why legal slavery did not appear until the 1660's suggests that assumptions about the relation between slavery and racial prejudice should be reexamined and that explanations for the different treatment of Black slaves in North and South America should be expanded.The Handlins explain the appearance of legal slavery by arguing that, during the 1660's, the position of White servants was improving relative to that of Black servants. Thus, the Handlins contend, Black and White servants heretofore treated alike, each attained a different status. There are, however, important objections to this argument. First, the Handlins cannot adequate!y demonstrate that the White servant's position was improving during and after the 1660's; several acts of the Maryland and Virginia legislatures indicate otherwise. Another flaw in the Handlins' interpretation is their assumption that prior to the establishment of legal slavery there was no discrimination against Black people. It is true that before the 1660's Black people were rarely called slaves. But this should not overshadow evidence from the 1630's on that points to racial discrimination without using the term slavery. Such discrimination sometimes stopped short of lifetime servitude or inherited status-the two attributes of true slavery-yet in other cases it included both. The Handlins' argument excludes the real possibility that Black people in the English colonies were never treated as the equals of White people.This possibility has important ramifications. If from the outset Black people were discriminated against, then legal slavery should be viewed as a reflection and an extension of racial prejudice rather than, as many hIstorians including the Handlins have argued, the cause of prejudice. In addition, the existence of discrimination before the advent of legal slavery offers a further explanation for the harsher treatment of Black slaves in North than in South America. Freyre and Tannenbaum have rightly argued that the lack of certain traditions in North America-such as a Roman conception of slavery and a Roman Catholic emphasis on equality-explains why the treatment of Black slaves was more severe there than in the Spanish and Portuguese colonies of South America. But this cannot be the whole explanation since it is merely negative, based only on a lack of something. A more compelling explanation is that the early and sometimes extreme racial discrimination in the English colonies helped determine the particular nature of the slavery that followed.Which of the following statements best describes the organization of the first paragraph of the passage?(A) A historical trend is sketched and an exception to that trend is cited.(B) Evidence for a historical irregularity is mentioned and a generalization from that evidence is advanced.(C) A paradox about the origins of an institution is pointed out and the author's explanation of the paradox is expounded.(D) A statement about a historical phenomenon is offered and a possible misinterpretation of that statement is addressed.(E) An interpretation of the rise of an institution is stated and evidence for that interpretation is provided.
