Now that you have studied the components of a homeostatic control system and their roles, it is time to put that knowledge to use. In this question, you will build a homeostatic control system. Drag and drop the items below in the appropriate order to represent a negative feedback homeostatic control system for body temperature regulation.
The missing part of the question is given as follows:
Muscles shiver to produce heat.
Body temperature rises.
Brain sends messages to muscles.
Thermoreceptors detect body temperature.
Brain processes temperature information.
Answer:
The correct answer is - Thermoreceptors detect body temperature -----> Brain processes temperature information ------> Brain sends messages to nucleus ------> Muscles shiver to produce heat --------> Body temperature rises.
Explanation:
The negative feedback mechanism is a mechanism used to correct the variation to its normal value. The appropriate order or sequence to show the negative feedback homeostatic control system for body temperature regulation is as follows:
Thrmoreceptors present on the skin of an individual detects the body temperature which is sent to the brain for the processing of the information received from receptors. After processing the information on temperature brain send messages to the nucleus which causes the shivering of the muscles to produce heat and body temperature rises accordingly.

A. Humans only
B. Prokaryotes
C. All living things
D. plants and animals
Answer:
C. All living things
Explanation:
DNA triplets that code for amino acids are called codons, they specify which amino acid will be added next during protein synthesis.
Hope this helps!
The DNA triplets that code for amino acids are common to all living things. The option (C) is correct.
What are amino acids?Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha amino acids appear in the genetic code.
Moreover, amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.
Hence, the term amino acid is short for α-amino [alpha-amino] carboxylic acid. Each molecule contains a central carbon (C) atom, called the α-carbon, to which both an amino and a carboxyl group are attached. The remaining two bonds of the α-carbon atom are generally satisfied by a hydrogen (H) atom and the R group.

The human body is made of different systems. Explain and provide an example of how a problem with one system
would affect other body systems.
Answer: A problem with one system could affect other body systems because our body systems rely on each other.
Explanation: Each of your body systems relies on the others to work well. Your respiratory system relies on your circulatory system to deliver the oxygen it gathers, while the muscles of your heart cannot function without the oxygen they receive from your lungs.
A problem with the cardiovascular system (circulatory system) such as heart attack will affect the respiratory system and other systems of the body.
There are various systems that make up the human body. Some examples of these systems that make up the human body are:
cardiovascular systemrespiratory systemreproductive systemdigestive systemendocrine systemurinary system etc.These various system are mostly interconnected. Most of them work and in hand to keep the body functioning well. a problem with one might affect the other systems. A good example is the circulator system (cardiovascular system) and the respiratory system.
The cardiovascular system consists of the heart, muscles, and structures that help in the circulation of blood in the body. Oxygen is a major component of blood. Thus, the cardiovascular system, relies on the proper functioning of the respiratory system to supply oxygen. In essence, they both rely on each other.
Problems such as heart attack will result in the Cardiovascular System not functioning very well, and as such other systems such as the respiratory system will be affected.
A diagram showing different organ systems of the human body is attached below.
Therefore, a problem with the cardiovascular system, such as heart attack, will affect other systems of the body.

D) nitrogen and oxygen
Answer:
A
Explanation:
Took the test
The name of two greenhouse gases that may be responsible for the increased ice melting in Greenland includes carbon dioxide and methane. Thus, the correct option for this question is C.
What are Greenhouse gases?Greenhouse gases may be defined as those gases that significantly allow solar radiations to enter but prevent the escape of heat radiations of longer wavelengths. The name of these gases may include carbon dioxide, methane, nitrous oxide, water vapor, CFCs, etc.
Carbon dioxide is the primary greenhouse gas contributing to recent climate change. Carbon dioxide enters the atmosphere through burning fossil fuels, solid waste, trees, and other biological materials.
Apart from this, it is a result of certain chemical reactions, such as cement manufacturing. Along with methane, they are the two greenhouse gases that are also responsible for the increased ice melting in Greenland.

Why do you think the population growth rate has slowed overall but remains high in less developed countries?
Answer:
Prosperity, Diseases, Education & more.
Explanation:
In continents like Africa you have a lot of diseases and a lot of children who die because of the bad environment, diseases, no food and no water. The education especially the sexual education there isn't good or they didn't even have that topic once in their life. The children are supposed to go to work to give money to the family. More children, more money, right? The biggest reason is poverty and bad education. In China for example they have a problem with too many people, that's why they can get only 1-2 children. In high educated and wealth countries people know it's harder to work with children. The work time, flexibility and more will be much harder with children. People there know about sexual education, how to have safe sex and all those things you learned. I live in Germany and we have a problem with people having no children.

Children are needed in emerging nations as a labor force and to care for their aging parents. Due to the lack of access to contraception and generally lower levels of female education in these nations, fertility rates are higher.
What is population growth?Population growth is defined as the growth due to the fact that the human population is not a static component, one of the main problems of the modern world. The majority of human history saw a relatively steady population size.
Due to outdated customs or a fear of educated women, some nations enforce the absence of education for women. The resources are not available in other nations. Some of the most distant locations, mostly in Africa, are still without access to birth control information. Even fewer people have access to birth control, so unintended pregnancies go uncontrolled.
Thus, children are needed in emerging nations as a labor force and to care for their aging parents. Due to the lack of access to contraception and generally lower levels of female education in these nations, fertility rates are higher.
