The statement that is NOT true of soils is: "All of Earth's systems are represented in a soil."
How much soil is important on earth ?Soil is a critical resource on Earth, as it is essential for supporting plant growth and providing a habitat for a wide variety of organisms.
While soils are complex and dynamic systems that interact with many other Earth systems, not all Earth systems are represented in a soil. For example, soils do not directly represent the atmosphere or the hydrosphere, although they interact with both of these systems in important ways.
The other three statements are true of soils:
Weathered parent material makes up most of the B-horizon: The B-horizon is typically composed of weathered rock and mineral fragments that have been transported downward from the A-horizon.
The C-horizon of a soil can contain unweathered rocks: The C-horizon is the deepest layer of a soil and can contain unweathered bedrock or other geological material.
Organic matter gives the A-horizon in a soil a dark color: The A-horizon is the uppermost layer of a soil and is often darker than lower layers due to the presence of organic matter, which can give it a dark brown or black color.

What are the differences between white blood cells and normal eukaryotic cells?
Answer:
White blood cells (WBCs) are specialized to respond to antigen and produce antibodies as well as undergo phagocytosis in response to toxic stimuli.
WBCs are part of immune system and there are five different kinds with specialized features.
In order to make a cell model, it is best to use a muscle cell and a nerve cell or neuron: there are pronounced structural differences and those are present throughout animal kingdom.
Lower animals ( such as insects, worms etc. ) have different immune system, however, they do have typical neuron and a muscle cell/skin cell (fibroblast). Such cell models are likely to be easy, distinct and bring you good grades without going through much complication and confusions of various organ systems and animal mod

Eyepiece magnification(EM) X Objective magnification (OM)= Overall Magnification:
Answer:
I. Overall magnification (TM) = x40
II. Overall magnification (TM) = x100
III. Overall magnification (TM) = x400
IV. Overall magnification (TM) = x1000
Explanation:
A microscope can be defined as an optical device that is typically used to make an enlarged (magnified) image of a minute (small) object and as such reveals all the little information about the object that cannot be seen by the natural human eye.
Mathematically, the overall (total) magnification of a microscope is given by the formula;
Overall magnification (TM) = Eyepiece magnification(EM) X Objective magnification (OM).
I. When EM = x10 and OM = x4
TM = EM * OM
TM = x10 * x4
TM = x40
II. When EM = x10 and OM = x10
TM = EM * OM
TM = x10 * x10
TM = x100
III. When EM = x10 and OM = x40
TM = EM * OM
TM = x10 * x40
TM = x400
IV. When EM = x10 and OM = x100
TM = EM * OM
TM = x10 * x100
TM = x1000

What are reef producing coral called? What is the coral reef composed of? How are they created? (Site 1)
Answer:
Reef producing coral is called hermatypic corals.
Coral reef is composed of hundreds to thousands of polyps which are tiny coral creatures.
Coral reefs are created when free-swimming coral larvae are attached to the hard surfaces or submerged rocks.
Explanation:
Reef producing coral is called hermatypic corals.
The coral reef is composed of hundreds to thousands of polyps which are tiny coral creatures. Each of the polyps secretes calcium carbonate.
Coral reefs are created when free-swimming coral larvae are attached to the hard surfaces or submerged rocks. These hard surfaces are basically along the edges of islands or continents.
TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Answer:
False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.
Explanation:
Hope this helps.
It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.
What is nuclear envelope made of?The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.
In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.
The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).
Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.
Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.
Thus, the given statement is true.

A long time ago, farmers discovered that if they grow the same
crops on a field, then after a few years, the crops grow more slowly. Why does
this happen?
Answer:
Because they don't have fertilizer.
Explanation:
Well, if this was a long time ago, then farmers did not have fertilizer. So, there are bacteria on the roots of plants that convert nitrogen into a usable form. It's very important for growing, and when farmers harvest the crop, not much of the nitrogen is returned to the land, so it is not as fertile. Fertilizer is largely consisted of nitrogen, so that is why farmers use fertilizers today. But "a long time ago," farmers did not have fertilizer.
A strand of DNA consists of 35% adenine. What is the percentage of guanine in that same molecule
of DNA?
Answer:
Explanation:
We know that the sample is 35% adenine, which tells us that it is also 35% thymine. We know that cytosine and guanine pair together and will be present in equal amounts, so we can divide this final total by 2 to find our answer. The sample is 35% adenine, 35% thymine, 15% guanine, and 15% cytosine.
Answer:
25%

How can the freezing of surface waters make the water that is left unfrozen denser
Explanation:
When an aqueous solution freezes, the unfrozen solution becomes denser. That's because some of the water has been removed as ice. However, the solutes remain dissolved in a solution with a smaller liquid volume. The concentration of the solution increases, so the density increases.
this is because water expands as it gets cold hence floating leaving the unfrozen water dense
Plants take in carbon dioxide and release gas
Answer:
yes, but by gas you mean oxygen right?
Explanation:
Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

Answer:
The correct answer would be - option C. the time that it takes you to get to the school.
Explanation:
The dependent variable is the factor or variable in any research or experiment is the variable that depends on the independent variable which means it changes with the change in the independent variable.
Here the time the different vehicle takes to get to the school is a dependent variable as it depends on the fact that which vehicle is using and changes with the change in the type of vehicle.

Why is animal testing bad?
Answer:
Explanation:
Animal experiments may result in clinical trials of biologically faulty or even harmful substances, thereby exposing patients to unnecessary risk and wasting scarce research resources. Animal toxicity studies are poor predictors of toxic effects of drugs in humans.
Answer:
Experimenting with animals is not justified with anything, they practically play with beings that have life, emotions and that feel pain like all living beings.
Advances the experiments that are done on them, are not used, or the purpose is simply lost, as well as their life.
