Nuclear power plants use a fission reaction of uranium to generate heat to power a generator. A fission reaction is a chain reac

tion that continues to build and create more heat. How is the chain reaction controlled?
A.
The amount of uranium fuel can be reduced to slow the chain reaction down.
B.
The plant uses control rods that can be inserted into the reaction vessel to control the reaction.
C.
Water is added to the reaction to the reaction vessel to cool it down and slow the chain reaction.
D.
The extra heat that is created from the chain reaction is released into the air and keeps the reaction under control.

Answer:

C.)organs are a group of two or more different types of tissues that work together to perform a specific function

Explanation:

Cells of similar function are grouped together into tissues. For example, cardiac muscle tissue is present only in the heart, and made up of specialised cells called cardiomyocytes, or cardiac muscle cells. These cells contract to pump blood around the body.

The heart is an organ, consisting of multiple types of tissue including cardiac muscle tissue, connective tissue, blood vessels and epithelial tissue. Therefore, organs represent a group of at least two types of tissue that work together to carry out functions in the body.

What are two different kinds of rock that are easily weathered by carbonic acid?
horsena [70]
Limestone and marble are the two rocks that are easily weathered by carbonic acid. Two kinds of weathering mostly affect the rocks. and they are physical weathering and chemical weathering. The above mentioned two rocks are highly affected by carbonic acid. The appeareance of these kind of rocks change their structure due to erosion very regularly. Caronation is the type of chemical weathering that affects the rocks limestone and marble. The carbonic acide is formed by the reaction of carbon dioxide in the air and water in the rivers. This carbonic acid results in weathering.

What is the temperature of a water body containing a 90% saturation and 11.5 ppm of dissolved oxygen?
ozzi
Using the chart that has been provided, we may determine water temperature. We do this by drawing a straight line form the bottom scale which has the ppm of oxygen dissolved to the middle scale which has the percentage saturation.

The line starts from 11.5 ppm on the bottom scale and goes to 90% on the middle scale. Next, we continue this line, without changing its slope, to the third scale showing temperature. We see that it crosses the temperature scale at 4°C.

The temperature of the water is 4 °C.
