Answer:

A scientific hypothesis is the initial building block in the scientific method. Many describe it as an "educated guess," based on prior knowledge and observation. ... A hypothesis also includes an explanation of why the guess may be correct, according to National Science Teachers Association.

Answer:

Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing

The basic idea of a hypothesis is that there is no pre-determined outcome. ... A key function in this step in the scientific method is deriving predictions from the hypotheses about the results of future experiments, and then performing those experiments to see whether they support the predictions

What product do all three reactions in Model 2 have in common?
belka [17]

Answer;

-They all provide water

Explanation;

In reaction A, the reactants are glucose and fructose , and the products are Sucrose and water. This is a condensation reaction, following the combination of two monosaccharides (glucose and fructose) forming a dissaccharide (sucrose) and water.

In reaction B, the reactants are two amino acids, that results to formation of a dipeptide and water; this is also a condensation reaction joining two amino acids monomers, to form a dipeptide and water.

-In reaction C, a monoglyceride combines with a fatty acid to form a diglyceride and water. This is also an example of a condensation reaction that results to formation of a diglyceride and water.

Therefore, the similarity of all the reactions is that they are all condensation reactions, with water as a common product.

) Which of the following statements about transcriptional regulators is false? (a) Transcriptional regulators usually interact w
OverLord2011 [107]

The false statement is: (a) Transcriptional regulators usually interact with the sugar–phosphate backbone on the outside of the double helix to determine which DNA sequence to bind.

Transcriptional regulator or factor is protein with the ability to control and regulate gene expression at the transcription level by binding to DNA. Transcriptional factors have domain-DNA-binding domain which contains structural motif that recognizes DNA and it is responsible for the attachment to specific DNA sequence. It usually binds to the DNA major groove (hydrogen bonding) because it is less degenerate than that of the DNA minor groove.  

Transcriptional factors also contain trans-activating domain for the binding of other proteins and signal-sensing domain for the detection of external signals.

HELP PLEASE!<br> Explain the Linnaean system of classifying organisms.
Nady [450]

Answer:

The Linnaean system is based on similarities in obvious physical traits. It consists of a hierarchy of taxa, from the kingdom to the species. Each species is given a unique two-word Latin name. The recently added domain is a larger and more inclusive taxon than the kingdom.
