Answer:
Can you please explain the question your trying to ask in more detail if you can please?
Explanation:
I assume this photo has the labels you are talking about.
DNA double helix consists of two strands that wind around each other with their nucleotides liked.-> it's the structure number 5
nucleosome- it's a segment of DNA wound in sequence around eight histones (proteins)- number 2
Histone- proteins with DNA around them, forming the nucleosome- number 4
Tight helical fiber- chromatin <span>coiled very tightly- 3
Cromosome- </span><span>chromatin condensed even tighter forming a X shape.- 1</span>
Answer:
525 grams
Explanation:
Assuming the solution to be prepared is 15% by weight calcium chloride, it means 15 grams of calcium chloride will be in 100 mL of solution.
To calculate the amount needed to make 3500 mL solution;
15 g is required to make 100 mL
X g is required to make 3500 mL
X = 15 x 3500/100
= 525 g
<em>Therefore, 525 grams of calcium chloride will be needed to make 15%, 3500 mL of calcium chloride solution.</em>
Answer and Explanation:
In a cell, the smaller the surface area in relation to its volume, the lower the rate of diffusion. The ratio of surface area to volume of an object decreases sharply with increase in its size. The materials move across the cell rapidly because the cell has a larger surface area to volume ratio thus the rate of diffusion of materials is high.
