Answer:
B. They are considered stable over a lifetime
Explanation:
The only statement that is not true concerning the definition of life in general is that "They are stable over time." This can be proven in the early years of earth's life wherein different microorganism and macroorganism lives. Over time, they evolved into another species that is most suitable to the kind of envionment the earth is evolving.

In the human body, which of the following is considered an external defense in the prevention of disease? Mucous O Histamines O Antibodies O Fever
Answer:
I believe it would be Mucous
Explanation:
Since Histamines and Antibodies are chemicals that are inside a human body they are not an external defense. Also, a fever can only happen if the disease gets inside the body, thus its not an external defense. All this leaves only one option out and that is Mucous.
Answer:
Mucous

The chemical equation below summarizes the process of photosynthesis.
(604 (1) 0 + 111e13) và (O2 + CK Og
Where is the energy shown in the equation transferred as a result of photosynthesis?
into water
into the air
into sugars
into the ground
Answer:
The chemical equation of Photosynthesis in the question is not clear but the energy goes into water.
The answer is "Into Water"
Explanation:
Photosynthesis is a metabolic reaction which involves the synthesis of sugars (Glucose) in plants using carbondioxide and water input in the presence of sunlight. Photosynthesis, which occurs in the Chloroplast of plant cells, occurs in two stages viz: light dependent stage and light-independent stage.
The light dependent stage involves the production of ATP and NADPH molecules, which will be used in the light-independent stage. The chemical equation of photosynthesis is as follows:
6CO2 + 6H2O ---light energy--> C6H12O6 + 6O2
The light energy input in this reaction (from sunlight) is used in the light-dependent stage to break down water molecules, a process called PHOTOLYSIS OF WATER. The photolysis of water releases electrons and protons used to build a proton pump for the synthesis of ATP.
Therefore, the energy input from photosynthetic process goes into water.
Look at the chemical reaction below.

How does this image compare to the white blood cells you saw using Stella’s compound microscope? What are the pros and cons of using electron and compound microscopes? In your response consider cost and ease of use.
Answer:
The Resolution and Magnify power are the major differences between the electron microscope compare to compound microscope. This is due to the source of power for the operation,Light rays of (400-700nm) are used by the compound microscopes,while short frequencies beam of electrons of( 1 nm)are used by the Electron Microscope.
The compound microscope consists of objective lens with short focal length.They are therefore used for magnification of tiny objects.While the E. microscope makes use of beam of electrons(compare to light rays in the compound microscope) with higher resolutions.The beam of electrons are focused by magnetic lenses to give images.
Electron microscope is cumbersome to use,it is expensive, requires a lot of expertise, and occupies large space.
Compound are less expensive with low maintenance,it does not requires expertise;very easy to operate, and can easily be moved about.
There is low risk of radiation with compound,lower magnification,both dead and living creatures can be used.
E.microscope,has high radiation risk,higher magnification, with only dead materials.
Explanation:
White blood cells are the immune cells that protect the body. They are also known as leukocytes or leucocytes.
The compound microscope magnifies objects lesser than the electron microscope. We can see higher magnified things in the electron microscope.
Pros and cons of electron and compound microscopeCompound microscopes are easier to move and set up because they are small and light.Electron microscopes are heavy and higher. They are harder to set up and move.Electron microscopes use electromagnet glasses, whereas compound microscopes use glass lenses.Compound microscopes are cheaper than electron microscopes.Thus, these are the pros and cons of Compound microscopes and Electron microscopes.

Why do phospholipids form a bilayer in water? The phosphate portions repel each other. The hydrophilic and hydrophobic parts attract each other. The phosphate portions attract water, and the lipid portions repel water. The lipid portions attract water, and the phosphate portions repel water.
Answer: The phosphate portions attract water, and the lipid portions repel water.
Explanation:
Lipids are hydrophobic, while phosphates are hydrophilic. The lipid tails of phospholipids repel water and attract other lipid tails, so they are always on the inside of the bilayer, keeping them away from the water. The phosphate portions attract water, so they face the outside of the bilayer.
Phospholipids form a bilayer in water because the phosphate portions attract water, and the lipid portions repel water. Thus, the correct option for this question is C.
What is Phospholipid?Phospholipid may be defined as an amphipathic molecule that is significantly constructed from four components. They are:
Fatty acids.A phosphate.Alcohol is attached to the phosphate.A platform to which the fatty acids are attached.The platform on which phospholipids are built may be glycerol or sphingosine. A phospholipid is typically constructed of phosphate and lipids groups.
Among which phosphate portion is hydrophilic which attracts water molecules, while lipid portions are typically hydrophobic that repel water molecules. The lipids molecules are generally insoluble in water while soluble in organic solvents like chloroform, benzene, etc.
Therefore, due to the structural and functional differences phospholipids form a bilayer in water. Thus, the correct option for this question is C.

Match the hydrologic term to its definition.
Answer:
1st term- groundwater discharge
2nd term- subsurface runoff
3rd term- surface runoff
4th term- groundwater runoff
Explanation:
I hope this helps:)
Surface runoff: falling rainwater that flows over the ground.
Subsurface runoff: the water that infiltrates in the vadose zone; an example is falling rainwater that gets absorbed into the soil
Groundwater runoff: describes water pulled by gravity across land's surface, replenishing groundwater and surface water as it percolates into an aquifer.
Groundwater discharge: this describes the movement of groundwater from the subsurface to the surface i.e. groundwater returns back to land.
How do you explain surface runoff?Runoff is nothing more than water "running off" the land surface. Just as the water you wash your car with runs off down the driveway as you work, the rain that Mother Nature covers the landscape with runs off downhill, too (due to gravity). Runoff is an important component of the natural water cycle.
What is a runoff in groundwater?Runoff is the water that is pulled by gravity across land's surface, replenishing groundwater and surface water as it percolates into an aquifer or moves into a river, stream, or watershed.
