What are Lipids?Lipids are defined as a broad group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, phospholipids, and others. Important functions of lipids include storing energy, signaling and serving as structural components of cell membranes.
A lipid is a type of organic compound that is insoluble in water that includes fats, waxes, oils, hormones, and some components of membranes and serves as energy-storing molecules and chemical messengers.
When we arrange the elution on the basis of charge, triglyceride and cholesterol have no charge placed on first and second respectively, while sphingosine has 1 charge. and phosphatidyl serine and sphingomyelin have more than 2 charges
Thus, the lipids in order of elution by placing the first lipid to elute at the top are as follows:

Answer:
B is correct
Explanation:
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

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.

The Cell-mediated response is a chain reaction of antigens and Interleukins that results in:
A. The swelling of fluid and clotting elements to a damaged area.
B. The differentiation of helper T cells into cytotoxic T cells to destroy pathogens.
C. The production of macrophages to use phagocytosis on pathogens.
D. The differentiation of effector B cells into plasma cells to make antibodies.
The Cell-mediated response results in the production of macrophages to use phagocytosis on pathogens. The correct option is C.
Cell mediated immune response occurs when an invading antigen causes the release of cytokines (Interleukins), differentiation of T cells and production of macrophages.
Macrophages are produced through the differenciation of monocytes. They are further activated during an infection through the macrophage-activating cytokine (Interleukins).
Phagocytosis is the process used by immune cells such as macrophages which involves ingesting and eliminating pathogenic microorganisms.
Cell-mediated response dosent result to differenciation of helper T cells into cytotoxic T cells rather it leads to the activation of cytotoxic T cells. Therefore B is wrong.
Cell-mediated response dosen't lead to the production of antibodies therefore option D is wrong.

Given the gene sequence GGACCGTCGATCTTC, which of the following choices would represent an inversion mutation?
A. CCACCGTCGATCTTC
B. GGACTCGATCTTC
C. GGACCGTCGATCTTC
D. GGACCGTCGATCCTT
Reset Selection
ASAP
Answer:
D. GGACCGTCGATCCTT
Explanation:
Mutation refers to any change in the nucleotide sequence of a gene. Mutation can be of different types depending on how it occurs. According to the question, an INVERSION mutation is a type of mutation in which a segment of a gene gets broken off and reattached in another way on the same DNA. Hence, the only change in inversion mutation is the arrangement of the nucleotide bases on the gene.
Considering the nucleotide sequence: GGACCGTCGATCTTC, the sequence that describes an occurrence of inversion mutation is: GGACCGTCGATCCTT because the segment TTC in the original sequence has been rearranged as CTT in the mutated sequence.
Importance of antimicrobial emulsion
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.
