The structure the arrow is pointing to is the nucleus and it helps store genetic material (DNA) in living cells.

<h3>What is an organelle?</h3>

Organelle is a specialized structure found inside cells that carries out a specific life process. examples are ribosomes, vacuoles, nucleus etc.

The nucleus is the large membrane-enclosed organelle found in eukaryotic cells which contains genetic material.

The nucleus is located at the center of living cells and it functions to store genetic material called DNA. The DNA is transferred to offsprings for inheritance of traits.

According to this question, a microscopic image of a cell is shown. The arrow pointed to the nucleus of the cell.

Calculate the average atomic mass of element X using the table below. Then use the periodic table to identify the element. Separ
Ksenya-84 [330]

Answer:

126.8, Iodine

Explanation:

  • mass ×abundance/100
  • (126.9045×80.45/100)+(126.0015×17.23/100)+(128.2230×2.23/100)
  • 102.1+21.7+3=126.8

<em>IODINE</em><em> </em><em>has</em><em> </em><em>an</em><em> </em><em>atomic</em><em> </em><em>mass</em><em> </em><em>of</em><em> </em>126.8 or 126.9

Calculate the mass (grams) of 0.750 moles of Al2(Cr2O7)3
garik1379 [7]

Answer:

526g is the mass of this sample

Explanation:

To solve this question we must, as first, find the <em>molar mass </em>of Al₂(Cr₂O₇)₃ using the periodic table. The molar mass is defined as the mass of this compound per mole. With this value we can find the mass in 0.750 moles as follows:

<em>Molar mass Al₂(Cr₂O₇)₃</em>

2Al = 2*26.98g/mol = 53.96g/mol

6 Cr = 6*51.9961g/mol = 311.9766g/mol

21 O = 21*15.999g/mol = 335.979g/mol

53.96g/mol + 311.9766g/mol + 335.979g/mol

= 701.9156g/mol

The mass of 0.750 moles is:

0.750 moles * (701.9156g / mol) =

<h3>526g is the mass of this sample</h3>

Elle wanted to test how temperature affects the rate of evaporation. She had three setups:
Pie

Answer:

Temperature

Explanation:

Here the factor that Elle is controlling is the temperature. So temperature here is the independent variable and the dependent variable is the rate of evaporation of water.  Independent variable is controlled during the experiment setup and the outcome of the dependent variable depends on the independent variable.
