An illustration of a cell interacting with its environment is provided.
The illustration best represents which of the following ?
A.Water moving into a cell by the process of osmosis
B.Passive transport of solute into the cell by diffusion
C.Active transport of solute into the cell using energy
D.Water leaving the cell by the process of osmosis
Answers
In the cell, there is passive transport of solute into the cell by the process of diffusion. So the correct option is B.
What is diffusion?Diffusion is a phenomenon that happens when molecules move randomly and results in a net movement of matter from a high concentration area to a low concentration area. The scent of a flower that swiftly fills a room's quiet air is a common illustration.
Thermal energy is transferred or diffused from a higher to a lower temperature through the process of heat conduction in fluids. In order for a nuclear reactor to function, neutrons must diffuse through a material that frequently scatters them but only sometimes absorbs them.
It is discovered that the concentration gradient is proportional to the rate of flow of the dispersing material. If c is the substance's concentration, x is perpendicular to this reference area, and D is the constant of proportionality, then j = D(dc/dx); dc/dx is the rate of growth of concentration in the direction x, and the minus sign denotes that the flow is from higher to lower concentration. The diffusivity, or D, controls the rate of diffusion.
Therefore, the correct option is B.

quizleet Using the information in the introduction on mutations and your knowledge of proteins, develop a hypothesis to explain how the changes in the MC1R protein amino acid sequence might affect its function.
Answers
Answer:
Dark colour occurs.
Explanation:
The amino acid changes in the MC1R protein may change the structure and function of the protein because the amino acids are the building blocks of proteins. This change in amino acid leads to increased production of eumelanin, which results in the dark color of the protein. So we can say that change in the amino acids leads to the change in the structure and function of MC1R protein.
An 8-mer oligopeptide has the following amino acids:
A D E E F M W Y (two Es are present)
Here is your evidence:
1. Edman degradation produces A.
2. CNBr produces a 5-mer and a 3-mer that contains W.
3. Chymotrypsin produces two dipeptides and a tetrapeptide. The tetrapeptide has a total net charge of -4 at pH 12.5.
4. Staphylococcal protease in phosphate buffer produces a tetrapeptide (4-mer), dipeptide, free D, and free W.
5. Staphylococcal protease in acetate buffer produces a pentapeptide (5-mer), dipeptide, and free W.
Put in the sequence of the 8-mer (use caps here) i.e. ABCDEFGH.

explain what an ion is and how ions are created; be able to describe the difference in the formation of a negative and a positive ion.
Answers
Answer:
An ion is an atom or group of atoms, that bears one or more positive/negative electrical charges. Ions are formed when a netrual atom loses or gains electrons. This loss/gain of electrons imparts a positive or negative charge to the neutral atom, making it an ion. The difference in the formation of a negative ion is that the atoms lose valence electrons to become positive ions (vice-versa with a positive ion, so the atom gains valence).

Two pea plants with purple flowers are crossed. Among the offspring, 63 have purple flowers, and 17 have white flowers. With a chi-square test, compare the observed numbers with a 3:1 ratio and determine if the the difference between observed and expected is statistically significant. Note: Chi-square critical value with 1 degree of freedom is 3.84 with alpha equal to 0.05
Answers
Answer:
Chi-square value = 0.6
The difference between the observed individuals and the expected individuals is not statistically significant. There is not enough evidence to reject the null hypothesis.
Explanation:
H₀= Individuals will be equally distributed
H₁ = Individuals will not be equally distributed.
• Chi square= ∑ ((O-E)²/E)
∑ is the sum of the terms
O are the Observed individuals
E are the Expected individuals
• Freedom degrees = 1
• Significance level, 5% = 0.05
• Table value/Critical value = 3.84
The number of observed individuals:
63 have purple flowers, 17 have white flowersTotal number of individuals, N = 80 = 63 + 17
Observed Genotypic frequencies:
F(PF) = 63/80 = 0.79F(pf) = 17/80 = 0.21p² + 2pq + q² = 1
p² + 2pq = F(PF)
0.79 + 0.21 = 1
The expected genotypic frequency:
F (PF)= 0.75
F (pf) = 0.25
The number of expected individuals:
PF= 0.75 x 80 = 60 wf = 0.25 x 80 = 20Chi square = sum (O-E)²/E
PF = (O-E)² /EPF =(63 - 60) ² / 60
PF = 0.15
pf = (O-E)² /Epf= (17 - 20)²/20
pf= 0.45
Chi square= sum ((O-E)²/E) = 0.15 + 0.45 = 0.60
Chi square = 0.6Degrees of freedom = 1 alpha 0.05 Table value/Critical value = 3.840.6 < 3.84 meaning that the difference between the observed individuals and the expected individuals is not statistically significant. There is not enough evidence to reject the null hypothesis. Probably both parentals were heterozygous for the trait.

Which of the following statements describes a way in which bacteria differ from animals and plants?
Answers
The BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.
Prokaryotic cells (i.e. bacteria and Archea) have no nuclei and lack organelles.In these cells (prokaryotic cells), the genetic material consists of a single circular chromosome localized in a region of the cytoplasm called the nucleoid.On the other hand, eukaryotic cells (e.g., plant cells and animal cells) have their genetic material delimited by a membrane-bound organelle known as the cell nucleus. Moreover, eukaryotic cells also have different types of membrane-bound organelles that carry out specialized functions in the cell (e.g., mitochondria, chloroplasts, Golgi apparatus, vacuoles, etc).In conclusion, the BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.

B: Living organisms take in oxygen and water to create food in the form of sugars and energy.
C: Living organisms breakdown sugar from food to combine with oxygen making usable energy
D: Living organisms take in oxygen and release carbon dioxide through the cells thereby providing energy.
Answers
Answer:
C. Living organisms breakdown sugar from food to combine with oxygen making usable energy.
Explanation:
Cellular respiration is about making food into energy. Since C is the only one with that aspect C can be the only answer.
The statement which best explains the general process of cellular respiration is: C: Living organisms breakdown sugar from food to combine with oxygen making usable energy.
Cellular respiration can be defined as a series of metabolic reactions which typically occur in living cells, so as to produce energy in the form of adenosine triphosphate (ATP).
Generally, high energy intermediates that can then be oxidized to make adenosine triphosphate (ATP) are created during cellular respiration.
Basically, the general process involved in cellular respiration can be represented by a single equation while using the following substances;
Glucose (Sugar).Oxygen.Carbon dioxide.Water.Adenosine triphosphate (ATP).[tex]Glucose + Oxygen ---> Carbon \;dioxide + Water + ATP[/tex]
In conclusion, all living organisms breakdown sugar or glucose from their food to combine with oxygen, so as to make usable energy during cellular respiration.
