Hi lovely! Here are your scientific questions that are testable: 

Does the type of liquid affect how fast an ice cube melts? 

Does changing the temperature of water affect the buoyancy of an egg?

Does the thickness of the wire affect the power of the circuit?


Hope I helped!

Why does frozen water take on the pattern it does (hint: it has to do with water’s polarity)?
damaskus [11]

When ice forms, one water molecule's hydrogen atoms form weak hydrogen bonds with the tops of the oxygen atoms of two other water molecules. Lining up the water molecules in this pattern takes up more space than randomly arranging them.

<h3>What is polarity?</h3>

A physical property of compounds that connects other physical properties like melting and boiling points, solubility, and intermolecular interactions between molecules is referred to as polarity.

When ice forms, one water molecule's hydrogen atoms form weak hydrogen bonds with the tops of the oxygen atoms of two other water molecules.

Lining up the water molecules in this pattern takes up more space than randomly arranging them.

When water freezes, the water molecules slow down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern, with molecules further apart than when the water was liquid.

Thus, because of this frozen water take on the pattern it does.

Short segments of newly synthesized DNA are joined into a continuous strand by _____.Short segments of newly synthesized DNA are
Sloan [31]

Answer:

a. Ligase

b. Ligase ( it's repeated)

Explanation:

DNA synthesis begins, therefore, by synthesizing a short segment of RNA called a primer, which primer is synthesized by an enzyme called Primasa. Primasa is an RNA polymerase that uses DNA as a template. All fragments of Okazaki begin with a Primer. Subsequently, the DNA polymerase III Holoenzyme performs the synthesis of the corresponding DNA fragment until it reaches the next primer. At that time, DNA polymerase Ia replaces the DNA polymerase Holoenzyme III. The DNA polymerase I is responsible for removing the RNA primer through its 5'P-3'OH exonueotic activity and at the same time fills the hole by synthesizing DNA.

Finally, the two Okazaki fragments have to be joined, it is necessary to link the 3'OH end of a fragment with the 5'P of the next fragment. This work of sealing and joining the successive fragments is done by Ligase.
