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.

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?

Answers

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.

When calcium carbonate is heated, it
decomposes into calcium oxide and carbon
dioxide. If 100 g of calcium carbonate are
decomposed, 56 g of calcium oxide is produced.
What would be the mass of the carbon dioxide
given off by the decomposition?
A. 448
B. 110 g
C. 156 g

Answers

Answer:

A. 44 g

Explanation:

First, you need to write a balanced equation:

CaCO₃ -> CaO + CO₂

Then, you need to find the molar mass of CaCO₃:

Ca = 40.078 amu

C = 12.0107 amu

3O = 47.9982 amu

_________________

100.0869 amu

Then, you calculate the moles of CaCO₃:

100 g ÷ 100.0869 amu = 0.9991 moles

In the balanced equation, we can see that the molar ratio of CaCO₃ and CO₂ is 1 : 1, so moles of CaCO₃ = moles of CO₂.

Now you need to find the molar mass of CO₂:

C = 12.0107 amu

2O = 31.9988 amu

________________

44.0095 amu

Finally, you can calculate the mass of CO₂ produced:

0.9991 moles * 44.0095 amu = 43.9698 g = 44 g

Hope that help

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.

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.

Answers

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.

Nitrogen fixation converts nitrogen gas to usable nitrogen for plants?

True
False

Answers

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.

Answers

Answer:

D - How trichoplax adhaerens eats by engulfing it's food

Phagocytosis is a process in which Trichoplax adhaerens eats by engulfing its food, which is in Option D. It is a process by which the cells engulf the food that is coming from the outside of the cell.

What is phagocytosis?

The cell has many organelles, such as the lysosome, vacuole, cell nucleus, etc., but each organelle has a special function, and one organelle cannot take over the function of another organelle. The lysosomes have a very unique and acidic environment that destroys the organelles, such as old organelles, and kills viruses, etc.

When outside food particles or pathogens enter the cell, they enter as a vacuole, and the cell transports them from the outside to the inside through a variety of processes. The cell then eats them, a process known as phagocytosis, and if it is a virus, the lysosome degrades it.

Hence, Phagocytosis is a process in which Trichoplax adhaerens eats by engulfing its food, which is in Option D.

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?

Answers

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.
