C

D

Answers
In order to identify whether unknown powder is baking soda or not, adding a small amount of vinegar to the powder would be the best test as it can be observed with the given table that only the baking soda reacts with vinegar. Thus, the correct option is A). Adding a small amount of vinegar to the powder.
What is the way to identity the baking soda?Baking soda is natural chemical that is commonly known as sodium bicarbonate. It is white in color and salt composed of a sodium cation. It often appears as a fine powder.
There are two ways to test whether the baking soda is still active or not. First, drop half teaspoon of baking soda into hot water and observe if it fizzes and forms bubbles, then it's still good. Second way, drop half teaspoon of soda into a small amount of vinegar and if it fizzes, it's still active.
Thus, it can be concluded that the baking soda reacts with the vinegar. So, in order to identify it just add small amount of vinegar to the powder.

Defend or refute the argument that the government has too large a presence in the agriculture industry.
Answers
1. Greater equality - redistribute income and wealth to improve equality of opportunity and equality of outcome.
2. Overcome market failure - markets fail to take into account externalities and are likely to under-produce public/merit goods.
3. Macroeconomic intervention - intervention to overcome prolonged recessions and reduce unemployment.
4. Disaster relief - only government can solve major health crisis such as pandemics.
Public funds and policies were aimed at promoting industry, and the agricultural sector was largely viewed as a source of resources for the growth of the nonagricultural sector.
What is Government?The government is referred to as an administrative body that helps to perform the function of the country by maintaining peace and order and implementing rules and laws described in the constitution and working for the welfare of its citizens.
Since the agri-food industry makes up the majority of global economic activity, poverty is closely related to it. Because agriculture employs half of all workers worldwide, the government has relatively significant involvement in the sector.
The enormous social and economic impact of agriculture contributes to other non-agricultural sector growth.

Answers
Answer:
Hi. You didn't show the maps, however, I can help by stating that a map showing the distribution of neighborhoods in Singapore would be more likely to be used by a government agency that seeks to promote equal opportunities between ethnic groups.
Explanation:
Singapore is a region with a great cultural diversity and a large number of foreigners, which allows many ethnic groups to come together and form neighborhoods that are distributed in the city. As we know, some ethnic groups are favored which makes the neighborhoods have better infrastructure in relation to the formed neighborhoods and less favored ethnicities.
A map showing these neighborhoods and their distribution in the city could be used for several reasons, however, in relation to the options shown in the question, it would be more likely that a government agency that seeks to promote equal opportunities between ethnic groups would make decisions based on the spatial pattern shown on the maps.
The individuals or organizations that would be most likely to make a decision based on the spatial pattern shown on the maps is a government agency that seeks to promote equal opportunities between ethnic groups.
Because the question does not contain the map that needs to be analyzed, I will help out by giving a general overview and using deductive analysis to help you out.
When a person uses a spatial pattern on a map to make a decision, then that person is trying to differentiate between various groups of people to make the best decision that would benefit them.
As a result of this, the most likely answer would be a government agency that seeks to promote equal opportunities between ethnic groups.

Chesapeake Bay is a:______
A. Deep, partially mixed estuary
B. Shallow, fjord-type estuary O
C. Deep, well-mixed estuary
D. Salt wedge estuary
E. Shallow, well-mixed estuary
Answers
Answer:
D. Salt wedge estuary
Explanation:
The Chesapeake Bay is the largest estuary in the United States. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula with its mouth of the Bay at the south end located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's 64,299-square-mile drainage basin, which covers parts of six states and all of Washington, D.C. / District of Columbia.
The Chesapeake Bay is a "shallow, well-mixed estuary."
This is because the Chesapeake Bay has an average depth of 21 feet or 7 meters.
The lower part of the Bay is considered salty from the Atlantic Ocean, while the upper part is considered fresh, which drains into the Bay; hence, it is a well-mixed bay.
The Chesapeake Bay is the biggest estuary in the United States.
Hence, in this case, it is concluded that the correct answer is option E. Shallow, well-mixed estuary.
