The small part of the nucleus where ribosomal subunit formation takes place is called the nucleolus. This structure is found in eukaryotic cells and takes up about 25 percent of the volume of the nucleus. This structure is said to be the brain of the nucleus. It is made up of ribobucleic acids or the RNA and proteins. Its primary function is to transcript the ribosomal RNA (rRNA) and to combine these with the proteins resulting to the formation of an incomplete ribosome. Since it is closely related to a chromosomal matter of a cell and important in the production of ribosome, this structure is correlated to be one of the cause of a number of diseases.
Both indicate the temperature at which the solid and liquid states of a substance are in equilibrium would be your answer.
This is beacause the melting point of a substance is the same as the freezing point of a substance. At this particular temp, the substance can be either a solid or a liquid.
hope this helps!
Answer:
option B = 0.410 g
Explanation:
The given measurement have five significant figures 41006. this measurement can be rounded to three significant figures i.e, 0.410 g.
All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.
Zero between the non zero digits are consider significant like 104 consist of three significant figures.
The zeros at the right side e.g 2400 are also significant. There are four significant figures are present.
Answer:
68.81ml
Explanation:
Using the formula:
CaVa = CbVb
Where;
Ca = concentration of acid (M)
Cb = concentration of base (M)
Va = volume of acid (ml)
Vb = volume of base (ml)
Based on the information given in this question;
Ca = 0.545M
Cb = 0.150M
Va = 250ml
Vb = ?
Using CaVa = CbVb
0.545/250 = 0.150/Vb
Cross multiply
250 × 0.150 = 0.545Vb
37.5 = 0.545Vb
Vb = 37.5/0.545
Vb = 68.81ml
