Answer:
B) Coating of microbe to aid phagocyte recognition
Explanation:
Opsonization is the process and mechanism which targets the foreign body and helps in the recognition of the pathogen by the phagocytic cells such as the macrophages and dendritic cell.
The opsonization enhances the process of phagocytosis as the opsonin substances which could be the antibodies, proteins or other molecules which could be easily recognised by the phagocytic cells gets attached to the pathogen.
Thus, Option-B is the correct answer.
Opsonization is the coating of a particle with proteins that facilitate phagocytosis of the particle by tissue macrophages and activated follicular dendritic cells (FDCs) as well as binding by receptors on peripheral blood cells
Answer:
See the answer below
Explanation:
Recall that: <em>Water potential = pressure potential + solute potential</em>
Since the system is an open one;
<em>Water potential = solute potential = -iCRT</em>
i = number of particles the molecle will make in water (1)
C = molar concentration
R = Pressure constant = 0.0831 liter bar/mole K
T = temperature in kelvin = 22 + 273 = 295 K
To calculate water potential on side A:
C = 1 M
Water potential = - (1 x 1 x 0.0831 x 295) = -24.51 bars
For side B:
C = 2 M
Water potential = - (1 x 2 x 0.0831 x 295) = -49.03 bars
b.
<em>Since side A has higher water potential than side B, water will flow from side A to side B until equilibrium is established between the two sides. Water always flows from the region of higher water potential to the region of lower water potential.</em>

The DNA has to replicate before mitosis to keep the number of chromosomes consistent. Hope this helps.
Explanation:
The effects of gamma radiation are investigated by studying plant germination, growth and development, and biochemical characteristics of maize. Maize dry seeds are exposed to a gamma source at doses ranging from 0.1 to 1 kGy. Our results show that the germination potential, expressed through the final germination percentage and the germination index, as well as the physiological parameters of maize seedlings (root and shoot lengths) decreased by increasing the irradiation dose. Moreover, plants derived from seeds exposed at higher doses did not survive more than 10 days. Biochemical differences based on photosynthetic pigment (chlorophyll a, chlorophyll b, carotenoids) content revealed an inversely proportional relationship to doses of exposure. Furthermore, the concentration of chlorophyll a was higher than chlorophyll b in both irradiated and non-irradiated seedlings. Electron spin resonance spectroscopy used to evaluate the amount of free radicals induced by gamma ray treatment demonstrates that the relative concentration of radiation-induced free radicals depends linearly on the absorbed
