Answer:
Because in immunoassays, secondary antibodies are used to bind the primary antibody to assist in detection, sorting and purification of target antigens
Explanation:
Secondary antibodies are commonly used for the indirect detection of a target to which a specific primary antibody is first bound. It must be unique in term of exhibiting high specificity and sensitivity to both the antibody species as well as the isotype of the primary antibody being used. High quality secondary antibodies are paramount in achieving meaningful results

Jon always keeps his bread in the cabinet, in the dark. Recently, his bread has been getting moldy rather quickly and needed to be thrown out. For an experiment, Jon puts two slices of the same brand of bread in the cabinet, in the fridge, in the sunlight (on the counter), and in the freezer. Jon leaves the bread in there for two months and checks it once every day. At the end of his experiment, Jon will look at all his data and compare to see which method keeps his bread fresh the longest.
What is the IV/DV/Control/Constant/Data Type?
IV:
DV:
Control:
Constant:
Data Type (Qual / Quan):
Answer:
IV: Method of preserving bread
DV: How long the bread stays fresh
Control: Bread kept in the cabinet
Constant: Same slice of bread, same brand of bread, same amount of time
Data Type: Quantitative
Explanation:
Independent variable is the variable that is manipulated or changed by the experimenter in an experiment. In this case, the independent variable is METHOD of PRESERVING BREAD or LOCATION OF KEEPING BREAD.
Dependent variable is the variable that is being measured in the experiment. The dependent variable responds to the changes made to the independent variable. In this case, How long the bread stays fresh is the dependent variable.
Constants are variables that the experimenter intentionally keeps unchanged throughout the experiment in order not to influence the result. In this experiment, the constants are: Same slice of bread (2 slices), same brand of bread, same amount of time (2 months).
Control group is the group that does not receive experimental treatment. The control group of this experiment will be the BREAD HE KEEPS IN THE CABINET.
Data type can either be quantitative or qualitative. The data type in this experiment is QUANTITATIVE because it involves the use of counts and numbers, which is time in this case.

describe the arrangements of epithelial and connective tissues in the four types of membranes.
Answer:
Membranes are thin layers of epithelial tissue usually bound to an underlying layer of connective tissue. Membranes cover, protect, or separate other structures or tissues in the body. The four types of membranes are: 1) cutaneous membranes; 2) serous membranes; 3) mucous membranes; and 4) synovial membranes.
Cutaneous, mucous, serous and synovial membrane have a thin layer of epithelial tissue which is bounded by a connective tissue under it.
What is epithelial tissue?"It is a type of body tissue that forms the covering on all internal and external surfaces of your body, lines body cavities and hollow organs and is the major tissue in glands."What is connective tissue?"It is a tissue that connects, supports, binds, or separates other tissues or organs."What is cutaneous membrane?It is also known as skin.It protects our body's tissue and organs from damage.What is mucous membrane?It is an inner lining of some organs and body cavities that produces mucous.What is serous membrane?"It line body cavities that do not open directly to the outside, and they cover the organs located in those cavities. "What is synovial membrane?These are layer of connective tissue present in joints, cartilages, etc. and they secrete synovial fluid.Hence, all the membranes are formed of epithelial tissue which is bound by an underlying connective tissue.

Why do we think that some cell signaling molecules have a long evolutionary history?
Answer: Cell signaling involves the relationship between a cell and its receptor which gets the hormones and other agents which controls the activity of the cell.
Explanation:
It can be classified as mechanical or biochemical depending upon the kind of signal. Mechanical signals are the forces produced by the cell or exerted by the cell. Biochemical signals are derived by the biomolecules like proteins, ions, gases, and lipids. These biomolecules have an evolutionary history as they are developed during the primitive atmosphere of earth by the inorganic molecules of carbon dioxide, methane, and water present in the primitive earth's atmosphere. These molecules are basis of development of life as they were responsible for generation of biomolecules like proteins, and lipids necessary for sustaining life on earth.

what happens when rain water hits sand
Answer:
it seapes through the water
Answer:
When rain falls to the ground, the water does not stop moving. Some of it flows along the land surface to streams or lakes, some is used by plants, some evaporates and returns to the atmosphere, and some seeps into the ground. Water seeps into the ground much like a glass of water poured onto a pile of sand.
Can you guys help me with this?
Answer:
The law of segregation states that genes have alternative forms, or alleles. In a diploid organism, the two alleles of a gene separate during meiosis and gamete formation; each sperm or egg carries only one allele of each pair. This law explains the 3:1 ratio of the F2 phenotype observed when monohybrids self-pollinate. Each organism inherits one allele for each gene from the parent. In heterozygous individuals, the two alleles are different, and expression of the dominant allele masks the phenotypic effect of the recessive allele. In hom0zygous individuals, the two alleles are identical.
The law of independent assortment states that the pair of alleles for a given gene segregates into gametes independently of the pair of alleles for any other gene. This law explains the 9:3:3:1 ratio of the F2 phenotypes in a cross between dihybrids.
Explanation:
The law of segregation explains that, during gamete formation, each gamete receives just one copy of the gene (allele) which is random. Therefore, if we have two heterozygotes (Aa), the possible genotypes are AA, aa, Aa and Aa. Therefore, the ratio of the dominant phenotype to the recessive is 3:1.
The law of independent assortment explains that the alleles of different genes are inherited independently of one another. That explains the 9:3:3:1 phenotype ratio when crossing two individuals heterozygous at two different genes

in what two ways does sun light increase the rate of transpiration
Answer:
mark as brainlliest
Explanation:
Plants transpire more rapidly in the light than in the dark. This is largely because light stimulates the opening of the stomata (mechanism). Light also speeds up transpiration by warming the leaf. Plants transpire more rapidly at higher temperatures because water evaporates more rapidly as the temperature rises

How are radiation, convection, and conduction used in green building design?
Answer:
To help reduce energy consumption in air conditioning
Explanation:
Radiation, convection, and conduction are different ways of heat movement, and in green buildings what we want to do is to save energy or use clean energies in all of the devices in the building, having this in mind green building design tries to use the positioning of the sun and air currents to mantain the temperature inside of the building as neutral as possible, fresh on the summer and warm on the winter, this will help lower the amount of energy used to mantain a stable temperature.
Why is there so little life at the bottom of the ocean?
Answer:
Lack of sunlight means no algae or plants to support the food chain, so food is scarce. Deep-sea animals must survive on the decaying scraps of dead organisms from the upper layers of the ocean, which sink to the bottom.
g A charged tRNA travels across a ribosome from the _______ site, to the _______ site, and then to the _______ site. A; E; P P; A; E P; E; A A; P; E E; P; A
Answer:
A; P; E
Explanation:
A tRNA molecule is a type of RNA found in the ribosomes of a cell. They play a major role in the translation process by binding to the mRNA in respective sites of the ribosome and carrying their corresponding amino acid to the growing polypeptide chain.
Ribosomes, which is the site of translation has three sites namely: A site, P site, and E site. tRNAs perform their roles by moving through these sites in the order: A to P to E.
Site E is the release site
If an ER signal sequence were added to its N-terminus, which structure would the engineered protein adopt
Answer:
The correct answer would be - structure with both N- terminal and C-terminal in the lumen side.
Explanation:
In eukaryotic cells, the cytosol is the site where protein synthesis takes place which is transported to the endoplasmic reticulum. The protein then moves to the endomembrane vesicle pathway from the endoplasmic reticulum. The transport of the proteins to the different organelles takes place from there as they destined and ultimately secreted from the cell.
In ER such proteins that contain ER signals at the N terminal of the protein are move into the lumen of the endoplasmic reticulum. So, both end N- terminal and C-terminal of the protein ae in the side of the ER lumen

If you put a protist into the same three environments, which environment would you expect its contractile vacuole to be most active
Answer: The completed part include the three environment, Hypertonic, isotonic and hypotonic.
The contractile vacuole will be most active in hypotonic environment.
Explanation:
The protist's contractile vacuole will be most active in hypotonic environment because it has lower concentration of solutes outside the cell than other solution which have salt particles which will allow water to constantly entering the cell through osmosis but the protist will counter this by it's contractile vacuole which let out water . The protist contractile vacuole will not hypertonic environment because it will cause the cell to shrink and lose water.
