Answer:
To study if the reuse of industrial treated wastewater may adversely affect life in a river basin system
Explanation:
The process of evaluation in science enables us to understand a given phenomenon from the natural world. Scientists have a standardized-objective method to investigate how the natural world works. This scientific method consists of the following steps: 1- to observe a given phenomenon form the real world, 2- to ask one or more questions about this phenomenon, 3- to raise a working hypothesis in order to explain these questions, 4-to test the hypothesis by experimental and/or observational procedures, 5- to obtain the results and conclusions. In this case, the scientific method can help to understand the effects of the industrial treated water in the life of the river system, and these results could be used as a starting point to predict its effects on other aquatic ecosystems.

steroids, also known more properly as anabolic–androgenic steroids, are steroidal androgens that include natural androgens like testosterone as well as synthetic androgens that are structurally related and have similar effects to testosterone.
Explanation:
Answer:
its any of a large class of organic compounds with a characteristic molecular structure containing four rings of carbon atoms (three six-membered and one five). They contain things such as testosterone and they are normally used as drugs to build up muscles in the body.

A. the cannon ball will crash into space B. the cannon ball will break orbit and go off into space. C. The cannon ball will have an elliptical orbit
The option that happens if the cannon ball's velocity is slightly faster than the circular orbit speed is option C: The cannon ball will have an elliptical orbit.
What is the Newton's cannonball illustration about?The Newton's cannonball illustration states that when a given ball is said to have gone or travels a little more faster than that of the circular velocity, it will create a kind of an elliptical orbit with the cannon and this is done at the perigee which is said to be the closest point in the orbit.
Note also that If the ball is said to have travels at the escape velocity, the orbit will be tend to open.
Therefore, The option that happens if the cannon ball's velocity is slightly faster than the circular orbit speed is option C: The cannon ball will have an elliptical orbit is correct.

1. Why would cells in some organs be consuming more oxygen than cells in other organs?
Answer:
Answer is below:
Explanation:
As oxygen molecules diffuse into the cell, they are consumed. But interstitial fluid volume is only a little more than half the intracellular fluid volume. The circulating blood must be brought close to the cells since the systemic organs (tissues) are connected in parallel.

What nutrient is matched with its correct function?
o A. fats: main source of energy for the body
O B. carbohydrates: building blocks of hormones and vitamins
OC. proteins: used for growth and repair of the body
O D vitamins: secondary source of energy
Answer:
C
Explanation:
Proteins are used to grow and restore muscle.
Dietary protein aids in cell renewal and repair. Children, teenagers, and expectant women all need protein for healthy growth and development. Therefore, option (C) is correct.
What is the role of protein?Protein is a nutrient that helps our body cells grow and heal (like blood and muscle cells). Your dry body weight is roughly 50% protein. Protein will be converted to carbohydrates if you don't consume enough of them to give you energy.
The body uses protein for a variety of purposes. It promotes metabolic reactions, supports tissue growth and repair, and synchronizes biological processes. Proteins give your body a structural foundation in addition to preserving a healthy pH and fluid balance.

what cellular process is occurring in the organelle labeled B?
Answer:
B. Cellular respiration
Explanation:
The cellular process that is occurring in the organelle labeled B is "Cellular respiration".
From the image, the organelle B is Mitochondria. Cellular respiration takes in the mitochondria and this is important because it leads in the production of ATP using the chemical energy that is found in glucose and other nutrients.
Mitochondria are known to be membrane-bound organelles. Their function is to generate most of the chemical energy that the cell needs for biochemical reactions.
Inversion is a type of mutation that
Answer:
the action of inverting something or the state of being inverted.
Explanation:
This type of mutation occurs a piece of DNA detaches from a chromosome during the reproductive stage and then reattaches to the chromosome in a reversed order. This will change the genetic code and make it very difficult to read.
Explain the relationship between DNA, genes and proteins and mutations.
Answer:
Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation

Cell theory teaches us that cells are the ?
Answer:
in biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
The three tenets to the cell theory are as described below:
All living organisms are composed of one or more cells.
The cell is the basic unit of structure and organization in organisms.
Cells arise from pre-existing cells.
There is no universally accepted definition of life. Some biologists consider non-cellular entities such as viruses living organisms,[1] and thus reasonably disagree with the first tenet
