Answer:
10⁶
Explanation:
A 1:100 serial dilution is a dilution in which the concentration decreases 100 fold (i.e., in each dilution the concentration of the culture must be multiplied by 10⁻²). The question above indicates that a three-step 1:100 dilution was applied, which means >> 10⁻² x 10⁻² x 10⁻² = 10⁻⁶. Moreover, the dilution factor can be calculated by dividing the volume of the diluted solution by the volume of the concentrated solution. The dilution factor is the inverse of dilution, thereby in this case this value is equal to 10⁶ (dilution = 10⁻⁶ >> dilution factor = 10⁶).

For some parents, their offspring have larger beak depths; for others it's smaller. How does the concept of variation of traits help to explain this?
Answer:
beak depth is a complex (quantitative) trait
Explanation:
Additive effects refer to the resulting effects of two or more genes acting together. Beak depth is a quantitative trait whose variation is determined by the additive effects of many genes acting together and the environment. In quantitative traits, variation is continuous and produces a range of phenotypes. In consequence, in this case, some offspring will have a larger average beak depth compared to their parents, whereas others will have a smaller average beak depth compared to their parents. It is due to the combination of alleles or 'additive effects' inherited from different parents, and the interaction between these genes and the environment. Heritability refers to the proportion of quantitative trait variation due to additive genetic factors: a higher heritability is due to the predominance of additive genetic effects and less influenced by environmental effects.

Answer: The answer is A Journal Reviewed By Peers
Explanation:
What type of organisms make up the majority of life on the surface of the pelagic zone?
chemosynthetic bacteria and invertebrates
seaweed and fish
mollusks and seaweed
plankton and algae
The types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae. That is the last option, as plankton and algae are the primary producers in the surface layer of the pelagic zone.
What are the zones of water?
The pelagic zone is the open ocean area that comprises the largest ecosystem on Earth. It is divided into different layers depending on the depth and amount of sunlight that penetrates the water. The surface layer of the pelagic zone, also known as the photic zone, is the layer that receives enough sunlight for photosynthesis to occur, and it is where most of the ocean's primary production takes place.
Hence, the types of organisms that make up the majority of life on the surface of the pelagic zone are plankton and algae, which is the last option.

After a check-up, Josephine's doctor told her that she had mild anosmia and that she can only distinguish about two thirds of the smells that most adults can.
Answer:
Yes.
Explanation:
Yes, she can only distinguish about two thirds of the smells because of the mild anosmia while on the other hand, if she has full anosmia she loss the ability of smell. Mild anosmia is the disease which takes half or some part of the ability but in the case of complete or full anosmia, the patient has lost the ability to smell completely so that's why mild anosmia enable her to distinguish about two thirds of the smells as compared to full loss of smell ability.

B. people discover more efficient ways to grow crops
C. people learn to live off less food
D. food costs more because there is less cropland
Answer:
Food costs more because there is less cropland
Explanation:
The amount of cropland available increases is the most likely result of converting farmland to urban development. So, the correct option is A.
What is Urban development?Urban planning is also called city planning, town planning, regional planning or rural planning which is defined as the technical and political process focused on the development and design of land use.
This development involves the transformation of an area into an urban state in various dimensions such as physical, geographical, economic and social through population and land use change. The conversion of farmland to urban development has many effects in terms of food security, reduced agricultural productivity, and agricultural labors.
The amount of cropland available increases is the most likely result of converting farmland to urban development.
Therefore, the correct option is A.

Nitrogen fixation converts nitrogen gas to usable nitrogen for plants?
True
False
Answer:
True, nitrogen fixation converts atmospheric nitrogen into nitrogen that can be used by plants.
Explanation:
Think about water. There's plenty of water on Earth, but very few is actually drinkable, at least for humans. So we have to fix it by filtering out dangerous bacteria in the water and other dangerous stuff before being able to actually drink it. Same with atmospheric nitrogen. It must be "fixed" before plants can actually use them.
Which of the following can a UAV do?
1. Provide information about geography
2. Provide information about soil nutrients
3. Provide information about soil hydration
4. Provide information about plant health
Answer:
Provide information about geography
Explanation:
UAVs are otherwise known as unmanned aerial vehicles or drones. They are usually remotely controlled and monitored from a screen. They can be flown over a large expanse of land to obtain geographical information such as the topography of an area, the distance between two points, the height above sea level, and so on.
Except the UAVs are specially designed and equipped with extra features, they cannot be used to obtain information relating to soil nutrients, soil hydration, or information about plant health on a field.
Hence, the correct answer would be option 1,
Answer: Provide information about geography

Answer:
C
Explanation:
ATP stands for adenosine triphosphate. An ATP molecule has ahead of adenose sugar and a tail of three phosphate groups. Energy is stored in the bonds between phosphate groups, so when your body needs energy, it breaks off some phosphate and releases energy to the immediate environment.

where's ATP produced in a cell and how?
The energy released during respiration is stored in the form of compounds called ATP molecules. They are produced by the enzyme ATP synthesis which converts ADP to ATP. It is located in the membrane of the cellular structures called mitochondria.
Answer:
Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts.

oil-rich countries in the middle east cover about 4% of earth's total land area but posses about 48% of the world's known oil reserves. what is the main reason for high concentration of reserves in this part of the world?
The correct answer is A. Geological processes.
Explanation
Oil is a hydrocarbon of fossil origin by geological processes that transforms large amounts of organic matter deposited on anoxic bottoms of seas or lake areas of the geological past, which were later covered by heavy layers of sediment. This causes organic materials to be transformed into oil by the heat and pressure of the upper layers. However, this phenomenon does not occur in all parts of the earth because in some, as in the case of the Middle East, there were large amounts of organic matter that became an oil reserve. So the correct answer is A.
