Answer:
volume of 2% saline (V₁) = 0.25ml
volume of water = 4.75ml
Explanation:
The requirement in the question is to obtain 0.1% of NaCl from 2% NaCl, and the process is dilution. The general dilution equation is guven by:
C₁V₁ = C₂V₂
where:
C₁ = initial concentration = 2%
V₁ = initial volume = ?
C₂ = final concentration = 0.1%
V₂ = final volume = 5ml
C₁V₁ = C₂V₂
calculating for V₁
∴ V₁ = (C₂V₂) ÷ C₁
= (0.1% × 5) ÷ 2%
V₁ = 0.25ml
Now, let us calculate the volume of water needed:
V₁ + Volume of water = V₂ (volume of 0.1% NaCl)
0.25 + volume of water = 5
volume of water = 5 - 0.25
volume of water = 4.75ml
Answer: (A) Primary landform: island, secoundary landform: beach gully.
Explanation: When waves crash, onshore they can make a significant impact on the landscape by shifting entire islands of sand and carving out rocky coastlines. Storm waves can even move boulders the size of cars above the high tide line, leaving massive boulder hundreds of feet inland. Wind is not the only cause of wild waves even tsunamis do, a tsunami is a wave created by a disturbance that displaces a large amount of water, like an earthquake or a landslide, and they often occur in clusters or sets.
Answer:
DNA helicase
Explanation:
The image of this question shows the replication of DNA into two identical copies. However, before this occurs, the double-stranded DNA needs to be unwound or separated so that each single strand can serve as a template for a new strand.
An enzyme called DNA helicase is responsible for the separation of the DNA molecule into single strands. After which, DNA polymerase begins to add nucleotides to each single strand of DNA.
