You are working in a lab trying to identify a single celled organism. You are not
sure if it is a Protist or a Moneran (Eubacteria or Archaebacteria). What test
would be most useful to determine its identity?
A. Put it in the sun and measure the oxygen levels
B. Determine if it is motile
C. Test its cells for chitin
D. Determine if it has a nucleus
Answers
The test that will be most useful to determine the identity of the single-celled organism is to "determine if it has a nucleus".
DIFFERENCE BETWEEN A PROTIST AND MONERAN:
A protist is a member of the kingdom protista characterized by it's single cells and eukaryotic nature.
On the other hand, a MONERAN is a member of the kingdom MONERA and characterized by it's unicellular and prokaryotic nature.
The major difference between Monera and protista is their prokaryotic and eukaryotic cells respectively. Prokaryotic cells do not have a membrane bound nucleus while an eukaryotic cell does.
Since the major difference between Monerans and protists is their possession of a membrane bound nucleus, the identity of the single-celled organism is to "determine if it has a nucleus".

Which of the following processes cycles matter through different parts of an ecosystem?
More than one answer may be correct.
1. the nitrogen cycle
2. the water cycle
3. the carbon cycle
Answers
Answer:
the nitrogen cycle, the water cycle, and the carbon cycle
Explanation:
The water, carbon, and nitrogen cycles move nutrients through the different parts of an ecosystem. Water moves through organisms and the environment in different phases. Carbon moves through an ecosystem in carbon dioxide, minerals, and organic compounds. Nitrogen moves through an ecosystem in nitrogen gas, ammonium, nitrates, and organic compounds.
The biogeochemical cycle is a pathway that circulates the chemicals through the abiotic and the biotic factor. The nitrogen, water, and carbon cycle through various regions of an ecosystem.
What is a biogeochemical cycle?The biogeochemical cycle is the movement of the chemicals and compounds of carbon, nitrogen, and water in the biosphere (biotic) and the atmosphere, lithosphere, and hydrosphere (abiotic) spheres of the earth.
These cycles move the nutrient through different spheres in the form of inorganic and organic compounds. It is an essential part of the ecosystem as they regulate the flow of the natural elements.
Therefore, option 1. nitrogen cycle, option 2. water cycle, and option 3. carbon cycle move through various parts of an ecosystem.

When the northern hemisphere points toward the sun, the southern hemisphere faces away from the sun. In this instance, it is:
A.
summer in North America, and winter in Australia.
B.
summer in North America and Australia.
C.
winter in North America, and summer in Australia.
Answers
Answer:
A
Explanation:
the northern hemisphere is the opposite from the southern hemisphere
Since northern and southern hemisphere are in opposite directions therefore, option (A) is correct.
Why are the seasons reversed in each hemisphere?The axis of rotation of the Earth is inclined with regard to the plane in which it orbits the sun. This is the root reason of the changing of the seasons. When the axis of the earth is aligned with the sun, summer arrives in that hemisphere of the planet. Expect winter to arrive when the axis of the earth is tilted away from the sun.
Different places of Earth receive the Sun's most direct rays throughout the year. When the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, the Northern Hemisphere experiences winter.

how does the respiratory and digestive system work together to maintain homeostasis
Answers
When groups of tissues work together, they are called organs. Some
examples of organs are the heart, lungs, skin, and stomach. When organs work together, they are called systems. For example, your heart, lungs, blood, and blood vessels work together. They make up the circulatory system.
There are eleven systems in the human body: muscular system, respiratory system, digestive system, integumentary system (skin), skeletal system, circulatory (or cardiovascular) system, excretory (or urinary) system, reproductive system, nervous system, lymphatic system, and endocrine system. Each system has a special job.
All of your body systems have to work together to keep you healthy. Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air. It also gets rid of carbon dioxide.

Your digestive system absorbs water and nutrients from the food you eat.
Your circulatory system carries oxygen, water, and nutrients to cells throughout your body. Wastes from the cells are eliminated by your respiratory system, your excretory system, and your skin. Your nervous system controls all these activities with electrical impulses. If any system in your body isn't working properly, other systems are affected.
Think of your body as a building. A building has a plumbing system, a heating system, a cooling system, an electrical system, and a support system. If any system in a building breaks down, other systems can be affected.
As one example, think about a building's electrical system. Suppose a mouse chewed through an electrical wire to a furnace. Without electricity, the heating system would not work. If this happened in very cold weather, the plumbing system could be affected. Water pipes might freeze and burst. If a lot of water leaked into the building's walls, its support system would be damaged. Like a building's systems, your body's systems have to work together.
The respiratory system brings oxygen into the lungs when you breathe. The digestive system breaks food down into nutrients such as glucose. Now the circulatory system enters the picture. It transports glucose and other nutrients from the digestive system to the cells.

Answers
Answer:
A chain of reactions is initiated upon soil flooding leading to reduced (low) soil redox potential (Eh, mV) conditions. These reactions include physical, chemical and biological processes that have significant implications for wetland plants.
Physical processes include restriction of atmospheric gas diffusion in the soil leading to depletion of soil oxygen and accumulation of carbon dioxide [4,5]. ... This process leads to oxygen depletion and reduction in soil oxidation reduction potential (Eh) followed by a chain of soil chemical changes.

recombinant DNA
Explanation:
In molecular biology, recombinant DNA molecules are genetic sequences formed by combining DNA material from different sources (i.e., organisms, populations, species, etc). Proteins produced from DNA recombinant molecules are known as recombinant proteins. Molecular cloning is the most widely used technique in molecular biology in order to produce recombinant DNA molecules. In this technique, a cloning vector such as, for example, a plasmid of a bacterium, is used to insert a foreign DNA fragment into another cell which is then expressed in the host cell.

1.What were some characteristics that the finches developed to give them an advantage in surviving?
2.How do you think that the one species of finch evolved into many different species, each with its own advantages?
3. In what ways do these advantages help the finches to survive and reproduce?
4. What might have happened if the finches didn't evolve into many different species?
Answers
Answer:
1. Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.
2. Summary: Changes in the size and form of the beak have enabled different species to utilize different food resources such as insects, seeds, nectar from cactus flowers as well as blood from iguanas, all driven by Darwinian selection
3. Medium ground finches with larger beaks could take advantage of alternate food
