Answer:
Water bath is used maintain temperature.
Explanation:
Water bath is laboratory container (equipment) filled with heated water and is used in conducting experiments that requires the maintainance of a certain temperature.
Digestive enzymes usually perform their functions at temperature of 37°C (optimal temperature) and they will need the use of water bath to maintain it. The body ranges at this temperature, thus 37°C will affect the activity of enzymes found in digestive tract. They will be more active in catalyzing the digestion reaction of carbohydrates and fats as this is their optimal temperature in the body.
Answer:
The answer is: Scientists can tell that punctuated equilibrium occurred if they examine the fossil record and see that one organism rapidly evolved different characteristics.
Explanation:
The theory regarding "punctuated equilibrium" followed after Darwin's Theory of Evolution. According to Darwin, species evolved over time. However, evidence supporting it is lacking when it comes to fossil record. He thought that this was because the fossils were incomplete.
Darwin's idea was contradicted by evolutionary scientists, named <u>Stephen Gould and Niles Eldrege.</u> According to them, species change after millions of years (this phase is called <u>"punctuated"</u>) and their change is sudden (and not gradual). This sudden change is very rapid, thus causing a fewer number of fossils being left behind. Most species who undergo speciation, occur in a different geographic location, thus leaving only a few number of fossils.
So, this explains the answer.

Answer: Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.

Answer:
translucent
Explanation:
Transparent means ALL light and ALL shapes are visible through, like a window.
Pigmented means that shapes are visible clearly, but not colors, like sunglasses.
Translucent means that shapes are somewhat visible (v. blurry,) and lights are somewhat also.
opaque is nothing in, nothing out. Solid.
