The correct answer is A.
Explanation
The image shows a map with the tectonic plates of the earth and four points are marked with the letters from A to D. The letter A indicates the collision of the Eurasian Plate and the Indian plate. The letter B indicates the border zone between Russia and the United States, however, there is no plate collision. The letter C marks are on the coast of Antarctica, but there is no collision between two plates. The letter D indicates an area on the equator, but it is not located on any plate collision. Therefore, the correct answer is A that shows the collision of the Eurasian Plate and the Indian plate where the great mountain chain of the Himalayas is formed where Mount Everest is located, the highest in the world with its summit at 8,849 meters above sea level. This is because many of the great mountain ranges of the world originate from the collision of plates such as the Andes and the Himalayas.
Antimicrobial susceptibility testing was performed to screen a novel compound. The MIC was found to be 10ng/mL. Use the following data to determine the percent recovery for each treatment group. What is the MBC and would you describe the antimicrobial tested as static or cidal?
Novel compound concentration CFU/mL Present Recovery
0ng mL 3.4 x 10^5
10ng/mL 2.4 x 10^5
20ng/mL 6.4 x 10^4
40ng/mL 1.4 x 10^4
80n mL 4.4 x 10^3
160n mL 0
Answer:
a) Percent recovery
100%, 70.58%, 4.11%, 1.29% , 0%
b) MBC = 160 ng mL
c) Static
Explanation:
A) Calculate the percent recovery for each group
i) for 0ng mL
( 3.4*10^5 / 3.4*10^5 ) * 100 = 100%
ii) for 10ng mL
( (2.4 * 10^5) / (3.4 * 10^5) ) * 100 = 70.58%
iii) for 20ng mL
( ( 6.4 * 10^5 ) / ( 3.4 * 10^5 ) ) * 100 = Nil
iv) for 40 ng mL
( ( 1.4 * 10^4 ) / ( 3.4 * 10^5 ) ) * 100 = 4.11 %
v) for 80 ng mL
( ( 4.4 * 10^3 ) / ( 3.4 * 10^5 ) ) * 100 = 1.29%
vi) for 160 n mL
percentage recovery = 0%
B) what is the MBC
The value of MBC = 160 n mL because at this concentration CFU/mL = 0
c) determine if the antimicrobial tested is static or cidal
condition : If, the ratio of MBC : MIC is ≤4 then novel compound is Cidal
MBC / MIC = 160ng / 10ng = 16 : 1
hence we can conclude that the antimicrobial tested is STATIC

Is the word ‘Autotroph’ rightly used to describe animals based on nutrition? Justify
Answer:
Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy
Answer: I don't think that they are known as 'Autotroph'
Explanation: Encyclopedic entry. An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.
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.

geosphere burying organisms
hydrosphere respiration of marine life
biosphere photosynthesis atmosphere burning things
Answer:
This question is incomplete, the question is asking to match each activity with the sphere to which it adds carbon or CO2.
ANSWERS:
Geosphere = burying organisms
hydrosphere = respiration of marine life
biosphere = photosynthesis atmosphere = burning things
Explanation:
This question describes the types of spheres we have. The respective activities that occur in each sphere that adds CO2 or carbon are as follows:
- Geosphere: This refers to the solid part of the Earth. Dead organisms are buried in the geosphere (soil) where their carbon remains can be deposited.
- Hydrosphere: This constitutes all of the water bodies (sea, river, stream, ocean) on the Earth. When marine organisms respire in water, carbon dioxide (CO2) is released.
- Biosphere: A sphere consisting of all living things (plant, animal, microbes etc.) on Earth. Plants as a living organisms photosynthesize and make use of carbon dioxide to produce glucose, which stores in the plant.
Atmosphere: The gaseous component of the Earth. Burning substances release carbon based gases into the atmosphere.

On a plant, stomates are small openings that regulate the passage of air and water vapor to and from the plant. Generally, the stomates open during sunlight and exchange gases with the atmosphere. The stomates of a few specialized desert plants can open only at night. The best explanation for the pattern of stomate opening and closing is that the desert plants are adapted to protect against
(1) harmful insects
(2) dust particles
(3) destructive plant disease
(4) excess water loss
(5) total energy loss
Please help me somebody answer this.
Answer:
4
Explanation:
this is because when the stomata opens during the day it would lose much water to the atmosphere so it tends to open during the night and close during the day

Which part of a mushroom would be eaten?
Thallus
Sporangium
Mycelium
Septum
Hyphae
Answer:
After it is released from the snailExcavata SporangiumExplanation:
Schistosoma life cycle:
1. Human excretes schistosomes eggs through feces and/or urine. These eggs eventually reach the water.
2. Once in the water, schistosomes eggs hatch and release immature larvae named miracides.
3. Miracides swim and penetrate a freshwater snail, which is an intermediary host.
4–5. Once inside the snail, miracides turn into sporocites and then into cercariae. Cercariae characterize by having a bifurcated tail. Snails release the cercariae in water, and they swim until they get in touch with a mammal. Once they reach the mammal, they penetrate the skin and get into the body. This is the stage in which the parasite becomes infectious to humans. Just a few cercariae are enough to infect a person.
6. When cercariae penetrate their host body, they lose their tails and turn into schistosomules. These new forms travel to the liver, where they end their maturation process.
7. Males and females mate in the liver and migrate to veins of the intestine or bladder. Once there, the females lay the eggs, which are then excreted by the host. And the cycle begins again.
--------------------------------------------------------------------------------------------------------
Excavata are asymmetrical protists. The group receives its name because of the appearance of the feeding groove. Excavata is composed of many protists. One of them is Parabasalid.
Parabasalids are parasitic protists, and one of them is Trichomonas vaginalis, which is transmitted sexually.
----------------------------------------------------------------------------------------------------------
Sporangium. This is the reproductive structure of the mushroom and the one that is usually eaten. Spores develop inside the sporangium. Its surface is covered by a protector cuticle. It can be eaten when it is closed or when it is already open. However, when open is tastier.
