c. DNA is located exclusively in the nucleus.
d. Protein is synthesized exclusively in the cytoplasm.
1) What two problems does the transfer of information from DNA to protein need to overcome?
a.
b.
Answer:
The two problems that the transfer of information from DNA to protein must overcome are:
How to bring the information from the nuclear DNA to the place of protein synthesis? How to convert this DNA information into amino acids and then into proteins?Explanation:
The genetic information is found in the DNA and depends on a specific sequence of nitrogenous bases. This information is transcribed into the messenger RNA, whose base sequence is organized into triplets and codons, each of which encodes an amino acid, as well as establishing the pattern for starting and stopping the synthesis of a protein.
How to bring the information from the nuclear DNA to the place of protein synthesis?The DNA must be transcribed into messenger RNA (mRNA), a process that occurs in the nucleus of the cell. mRNA leaves the nucleus and travels to the cytoplasm, where amino acid synthesis will take place.
How to convert this DNA information into amino acids and then into proteins?Once in the cytoplasm mRNA binds to ribosomes, structures in charge of translating the sequence of nitrogenous bases RNA to synthesize amino acids. The set of ribosomes and rough endoplasmic reticulum are in charge of the assembly of amino acids to produce peptides and proteins.

c. To display self-peptides to maintain self-tolerances
d. To display foreign peptides
e. All of the answers are correct.
Answer:
e. All of the answers are correct.
Explanation:
The major histocompatibility complex (MHC) is a locus that contains several polymorphic genes. These genes are known to encode different components of the immune system, especially cell-surface proteins which present antigens to the T cell receptors during adaptive immune responses. The MHC genes are classified into Class I, Class II and Class III:
1- MHC class I genes encode cell surface molecules that present peptides (antigens) to cytotoxic T lymphocytes (i.e., killer T cells)
2- MHC class II genes encode cell surface molecules that present antigens to CD4+ T cells
3- MHC class III genes encode proteins that are not involved in antigen presentation (i.e., components of the complement cascade, cytokines, etc)

In facilitated diffusion, do molecules move down their concentration gradient? Explain.
Answer:
Molecules move up the concentration gradient in facilitated diffusion, which requires ATP to be used as molecules naturally move from high to low concentration
Explanation:
: )
Molecules move down their concentration gradient in facilitated diffusion through channels of proteins.
For most molecules, movement through the membrane, with a significant rate, is only possible by the presence of transporter proteins (integral membrane proteins, which recognize substances with a high specificity, accelerating their translocation) or channels of proteins.
Transport proteins allow the facilitated diffusion of molecules, moving them along the free energy gradient (concentration gradient, charge gradient, or both), in the direction of thermodynamic equilibrium.
When a carrier protein binds to a solute, the protein changes shape in such a way that it carries the solute to the other side of the membrane.
Facilitated diffusion is similar to simple diffusion, since the molecules move from a region of higher to a lower concentration of solutes.
For example, by facilitated diffusion, chlorine ions move down their concentration gradient into the cell through chlorine channels.
Therefore, we can conclude that many molecules are assisted by transporter proteins for their diffusion through the plasma membrane, a process known as facilitated diffusion, where the molecules descend through their concentration gradient.

State the term used to describe an enzyme that functions within a cell.
Answer:
Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism
Explanation:
An intracellular enzymes can be referred to as endocyto enzymes. These are intracellular proteins that accomplish their function within the same cell that synthesized them. They can be either free in the cytosol or associated with an organelle -inside the organelle or fixated to it-.
--------------------------------------------
Enzymes are catalytic intracellular molecules or polypeptides that accelerate different natural chemical reactions. They have specific binding sites to substrate molecules and turn them into product molecules.
Enzymes are in charge of catalyzing cell metabolism. Since they are proteins, they share many properties with all polypeptides. One of these is that they have a limited temperature level at which they denaturalize.
According to the place where they accomplish their function, enzymes can be called
Plasm-specific enzymes ⇒ Their action field is the plasma ⇒ These are exportation proteins.Secreted or Exocyto enzymes ⇒ Their action field are tissues placed far away from where they were produced and released (for instance, the pancreas secretes and releases enzymes that accomplish their function in the duodene) ⇒ These are exportation proteins.Intracellular or Endocyto enzymes ⇒ All enzymes that accomplish their function within the same cell that synthesizes them ⇒ These are intracellular proteins.Within the cell, enzymes can be free in the cytosol, or fixated to an organelle.
Uniloculated enzymes ⇒ 100% cytosolic enzymes.Biloculated enzymes ⇒ They spend part of the time in the cytosol and part in organelles.--------------------------------------------------------

Darren used the following soil triangle to identify a sample of soil as sandy loam.
Soil texture triangle. Clay soil is approximately 45 percent or less sand, 50 percent or more clay, and 40 percent or less silt. Silty loam soil is approximately 50 percent or less sand, 30 percent or less clay, and 50 percent or more silt. Sandy clay soil is approximately 45 to 65 percent sand, 35 to 55 percent clay, and 25 percent or less silt. Sandy clay loam soil is approximately 45 to 80 percent sand, 20 to 35 percent clay, and 35 percent or less silt.
Which description of soil likely allowed Darren to make this identification?
Mostly large particles, with a gritty texture, 60% sand, 10% clay, and 30% silt
Mostly large particles, with a smooth texture, 40% sand, 50% clay, and 10% silt
Mostly small particles, with a smooth texture, 10% sand, 50% clay, and 40% silt
Mostly small particles, with a smooth texture, 30% sand, 30% clay, and 40% silt
Answer: I'm not sure but i think it's Mostly small particles, with a smooth texture, 10% sand, 50% clay, and 40% silt
Explanation:
Soil Texture is defined as the proportion of sand, silt, and clay-sized particles, which make up the composition of the soil.
The description that matches Darren's identification is that most small particles, with a smooth texture, are 10% sand, 50% clay, and 40% silt.
The soil texture can be explained as:
1. Clay in soil texture refers to the mineral soil particles that are less than 0.2 millimeters in diameter. Clay soil is 40% or more clay, less than 45% sand, and less than 40% slit.
2. Silt in the soil texture has a high percentage of sand and it feels smooth, having smooth textures. This soil has a high percentage of clay.
3. Sand is the largest mineral particle, which consists of the coarsest particles. The particles feel gritty and have a diameter of about 0.05 to 0.002 mm.

Answer:
Primary succession occurs in an area with no life and no soil but secondary succession happens in an area where an existing community was disrupted.
Explanation:
Ecological succession, which is the series of changes that occurs in an ecosystem over a period of time, can be divided into two types namely: primary succession and secondary succession.
- Primary succession is a kind of succession in which a bare surface or rock is colonized by certain organisms called PIONEERS. Primary succession occurs in an area with no life and no previous soil.
- On the contrary, secondary succession occurs in an area that has been previously colonized but disturbed as a result of natural occurrences e.g earthquake, wildfire, flooding etc.
