in yeast that has been genetically modified to be able to produce spider silk, the ________ is joined with the ________ .
A transgenic organism is an organism whose genome (DNA) has been altered by recombinant genetic engineering techniques. These techniques can be used to transfer exogenous genes within transgenic species.
In yeast that has been genetically modified to be able to produce spider silk, the spider silk CODING SEQUENCE is joined with the yeast REGULATORY SEQUENCE.In this case, transgenic yeast has the spider silk coding gene sequence (i.e., the exons) that encodes for the spider silk protein, whereas a regulatory gene sequence (e.g., a promoter gene sequence) from yeast have been preserved in order to regulate the expression of the target exogenous gene.The most important genetic engineering techniques used to create transgenic animals include DNA microinjection and retrovirus-mediated gene transfer.Learn more in:

what are buffers and why are they important to cells
Answer:
Buffers are chemicals that help a liquid resist changing its acidic properties when other chemicals are added that will normally cause a change in these properties.
Answer:
buffers are chemicals that help a liquid resist changing its acidic properties. the reason they are important to cells is because buffers maintain the right pH of a liquid.

which biomolecule is made of nucleotides and contain your dna
Answer:
Nucleic acids
Explanation:
macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material found in living organisms, all the way from single-celled bacteria to multicellular mammals like you and me.

which feature distinguishes protostomes from deuterostomes?
Answer:In Protostomes (“mouth first”), the mouth develops at the blastopore (Figure 3). In Deuterostomes (“mouth second”), the mouth develops at the other end of the gut (Figure 3) and the anus develops at the site of the blastopore. Protostomes include arthropods, mollusks, and annelids.

ou are designing a building that must minimize energy transfer in the form of heat loss. Describe a building shape that you think would minimize heat loss through the surface of the building, and explain how that shape relates to the surface area-to-volume ratio.
Answer: In principle, to minimise heat transfer through the building envelope the building shape should be as compact as possible,tending toward a cube.
Explanation:
A building's design should be compact and rounded to reduce heat loss through the surface. The optimum shape would be a sphere, but that is impractical for a building. It would be more practical to construct a building that is cylindrical or dome-shaped.
What should be the shape of building to minimize the heat?The optimum shape would be a sphere, but that is impractical for a building. It would be more practical to construct a building that is cylindrical or dome-shaped.
By lowering the building's surface area, this design limits the region where heat may escape from the structure. The surface area to volume ratio should be taken into account while trying to reduce heat loss.
A building that is compact and rounded, such a cylinder or dome, has a lower surface area-to-volume ratio than a building that is rectangular or square and has the same volume. Accordingly, less heat is lost from the building's surface in comparison to the heat that is kept inside the structure.
Additionally, a compact, rounded building will have fewer corners and edges, which are vulnerable to heat loss. Additionally, the structure can be angled to receive as much sun exposure as possible, which can add to the building's heating capacity during the winter.
Therefore, a building's design should be compact and rounded to reduce heat loss through the surface.

Answer:
For example, the nerve cells are elongated in shape and are thin and dainty. ... An animal cell does not have a cell wall
Explanation:
The size and shape of a cell are related to its function and are governed by four factors—(1) surface-volume ratio, (2) nucleocytoplasmic ratio, (3) rate of cellular activity, (4) cell associations. (1) Surface-volume Ratio: ADVERTISEMENTS: The cell membrane separates the inner content from the outer environment.

Which of the following is NOT a polymer?
Nucleotide
Polysaccharide
Triglyceride
Polypeptide
Answer:
Nucleotide ( monomer )
Explained Definition:
The classes of biological molecules may be grouped into the types of polymers they form and the monomers that act as subunits: Lipids - polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids
1. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.
2. Polysaccharides, also called glycans, are large polymers composed of hundreds of monosaccharide monomers. Unlike mono- and disaccharides, polysaccharides are not sweet and, in general, they are not soluble in water. Like disaccharides, the monomeric units of polysaccharides are linked together by glyosidic bonds.
3. Fatty acids form more complex lipid polymers called triglycerides, triacyclglycerols or triacyl glycerides when each single-bonded oxygen molecule bonds to a carbon that's part of a glycerol molecule. ... Triglycerides are also commonly found in foods, especially animal products
4. polymers are known as polypeptides; monomers are amino acids. Nucleic Acids - polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group
A student observes a reaction with an enzyme in a beaker. If nothing is removed from the beaker containing the reaction, what is the only thing the student must add to start the reaction again?
A.acids
B.enzymes
C.products
D.substrates
Answer:
90% Products, 10% Acids
Explanation:
enzymes are not consumed in a reaction. they remain mixed with reactants. if all products have reacted in the reaction and there's nothing left, the answer is products.
But acids promote chemical reactions at certain incidents. especially if it's an essential compound to the reaction.
Ex-: Sucrose is hydrolysed to Fructose and glucose by heating with an acid. but using sucrase, the same can be done.

How does the evolution of resistance in bacteria affect humans
Answer:
Bacteria, not humans or animals, become antibiotic-resistant. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antibiotic resistance leads to higher medical costs, prolonged hospital stays, and increased mortality.
