Column 3 is labeled step 7: Test for Diffusion of Glucose with entries Not observed, Light Blue initial color and Red after 15 minutes.
Analysis:
diffused though the semipermeable membrane.
Answer:
only glucose
Explanation:
The second student set up solutions that were in equilibrium.
On which principle Dialysis is based?Dialysis is based on the principles of osmosis, meaning the net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration. If the solute concentrations are the same on each side of the membrane, this spontaneous movement will not occur.
In passive diffusion, the small water molecules can move across the phospholipid bilayer seen in blue. This layer acts as a semi-permeable or selectively permeable membrane; its hydrophilic heads are attracted to water (seen facing outwards) while its water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Therefore, the second student set up solutions that were in equilibrium.

E. Decomposing dead organisms
Answer:
answer:
the.answer.is.b
B B B
One of the main ways that evolution occurs in prokaryotes is through mutations that occur during binary fission, which is present in Option C. In prokaryotes, which are single-celled organisms that lack a nucleus, evolution occurs primarily through mutations that occur during binary fission.
What is mutation?Prokaryotes, which include bacteria and archaea, are unicellular organisms that lack a nucleus and other membrane-bound organelles. They are known for their remarkable adaptability and ability to evolve rapidly in response to changing environmental conditions, and beneficial mutations that improve an organism's fitness, such as antibiotic resistance, can quickly spread through a population through natural selection.
Hence, one of the main ways that evolution occurs in prokaryotes is through mutations that occur during binary fission, which is present in Option C.

how much energy moves up from one trophic level to the next in the energy pyramid
Answer: Only about 10% of energy is transferred from one trophic level to the next. Most of the rest of the energy is lost through heat (energy expended, metabolic process, respiration) as it transfers along each level. The reason for this energy loss is found in the second law of thermodynamics which states: that as energy is transferred energy is lost.

Diversity among members of a species is important because diversity
a
increases the chances of survival under changing conditions.
b
ensures high levels of competition.
c
increases the available ecosystem resources.
d
ensures the variety of reproductive methods for a species.
Diversity among members of a species is important because diversity increases the chances of survival under changing conditions.
If a disease spreads throughout a species, the species with genetic diversity will survive. If the species does not have genetic diversity, they will be wiped out by the disease.

Na3C6H507
Answer:
Explanation:
Trisodium citrate has the chemical formula of Na3C6H5O7. It is sometimes referred to simply as "sodium citrate", though sodium citrate can refer to any of the three sodium salts of citric acid. It possesses a saline, mildly tart flavor. It is mildly basic and can be used along with citric acid to make biologically compatible buffers
Sodium citrate is chiefly used as a food additive, usually for flavor or as a preservative. Its E number is E331. Sodium citrate is employed as a flavoring agent in certain varieties of club soda. It is common as an ingredient in bratwurst, and is also used in commercial ready-to-drink beverages and drink mixes, contributing a tart flavor. It is found in gelatin mix[clarification needed], ice cream, yogurt, jams, sweets, milk powder, processed cheeses, carbonated beverages, and wine[citation needed], amongst others.
How are the equations for photosynthesis and cellular respiration related
HOPE THIS HELPS! :)
Notice that the equation for cellular respiration is the direct opposite of photosynthesis: Cellular Respiration: C 6 H 12 O 6 + 6O 2 → 6CO 2 + 6H 2 O. Photosynthesis: 6CO 2 + 6H 2 O → C 6 H 12 O 6 + 6O.
Please help me I really need help I am having a hard time with this question.
Answer:
I would prefer to have city water because you don't have to worry about it getting polluted unlike well water. The city water is maintained by the city while with the well water, you maintain it yourself. Even though it can be pricey, most people live in the city anyway, so there is easier access to it.
Explanation:
Answer:
Well Water
Explanation:
I would prefer well water, because city water had a lot of chemicals, and city water filters out minerals that are good for the body. Also, well water tastes ten times fresher than city water. Also, well water is easy to obtain if you already have a well, all you have to do is wither pump it up, or use a basket to scoop some out.

Do plants need to eat?Or do they acquire energy through a method different from animals?Write down the differences on how a tree and an ostrich acquire the energy they need for survival.
Plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.
What are Autotrophs?
Autotrophs are the organism that can produce its own food using light, water and carbon dioxide or some other chemicals. They are also known as primary producers.
The most familiar type of autotrophs are plant but apart from plants many different types of autotrophic organisms are there. For example, algae which live in water, phytoplankton which live in ocean and some type of bacteria.
Mostly autotrophs used the process called photosynthesis to make their own food. In this process, Autotrophs used energy from the Sun to convert water obtained from the soil and carbon dioxide obtained from the air to produce a carbohydrate called Glucose . It give energy to the plant.
Some rare autotrophs produces food through a process called Chemosynthesis . In this process, they make their own food using energy from chemical reaction combining Hydrogen Sulphide or Methane with oxygen . Organism that uses Chemosynthesis for making their food lives in extreme environment . For example, Bacteria live in active volcanoes oxidize sulphur to produce their own food.
Thus, plants acquire energy through a method known as photosynthesis which is different from animals. Plants make their food from the process called photosynthesis as they are autotrophs while animals depend on their food on plants and they are called herbivores.

Explain how DNA results in the expression of a gene using the following words: DNA, mRNA, tRNA, gene, transcription, and translation
Explanation:
in order for a gene to even be transcribed, it must be "turned on" or "expressed" meaning the nucleotides have moved away from each other. after it's expressed, the gene will unwrap and continue on with transcription, and make mRNA copy of a DNA strand. once RNA is made it will leave nucleus and enter cytoplasm to find a ribosome. once it attaches to ribosome, translation begins, and a tRNA will bind to anti-codon, and the building of a polypeptide/protein will begin.

Why is water called the universal solvent?
A.) Water is a nonpolar substance that dissolves polar substances
B.) Water can act as a solvent in many different solutions
C.) Water is a polar substance that dissolves nonpolar substances
D.) Water can act as a solute in many different solutions
Answer:
And, water is called the "universal solvent" because it dissolves more substances than any other liquid. ... This allows the water molecule to become attracted to many other different types of molecules.
Explanation:
B.) Water can act as a solvent in many different solutions.
Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. Water molecules have a polar arrangement of oxygen and hydrogen atoms—one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge.A water molecule consists of two hydrogen atoms and one oxygen atom. The three atoms make an angle; the H-O-H angle is approximately 104.5 degrees.Therefore, option B. is correct.
