What is the mass number for the neutral atom shown in the diagram below?

(I NEED HELP ASAP IM ON A TIMER )

I haven't taken biology in a few years, so I may be wrong, but to me it looks like mitosis, since it only divides once, and if I can see the picture correctly it looks like each cell contains the same amount of chromosomes, but I can't see the picture very well. If it helps here are some differences between meiosis and mitosis:

1. Cell Division

Mitosis: A somatic cell divides once. Cytokinesis (the division of the cytoplasm) occurs at the end of telophase.

Meiosis: A reproductive cell divides twice. Cytokinesis happens at the end of telophase I and telophase II.

2. Daughter Cell Number

Mitosis: Two daughter cells are produced. Each cell is diploid containing the same number of chromosomes.

Meiosis: Four daughter cells are produced. Each cell is haploid containing one-half the number of chromosomes as the original cell.

3. Genetic Composition

Mitosis: The resulting daughter cells in mitosis are genetic clones (they are genetically identical). No recombination or crossing over occur.

Meiosis: The resulting daughter cells contain different combinations of genes. Genetic recombination occurs as a result of the random segregation of homologous chromosomes into different cells and by the process of crossing over (transfer of genes between homologous chromosomes).

4. Length of Prophase

Mitosis: During the first mitotic stage, known as prophase, chromatin condenses into discrete chromosomes, the nuclear envelope breaks down, and spindle fibers form at opposite poles of the cell. A cell spends less time in prophase of mitosis than a cell in prophase I of meiosis.

Meiosis: Prophase I consists of five stages and lasts longer than prophase of mitosis. The five stages of meiotic prophase I are leptotene, zygotene, pachytene, diplotene, and diakinesis. These five stages do not occur in mitosis. Genetic recombination and crossing over take place during prophase I.

5. Tetrad Formation

Mitosis: Tetrad formation does not occur.

Meiosis: In prophase I, pairs of homologous chromosomes line up closely together forming what is called a tetrad. A tetrad consists of four chromatids (two sets of sister chromatids).

6. Chromosome Alignment in Metaphase

Mitosis: Sister chromatids (duplicated chromosome comprised of two identical chromosomes connected at the centromere region) align at the metaphase plate (a plane that is equally distant from the two cell poles).

Meiosis: Tetrads (homologous chromosome pairs) align at the metaphase plate in metaphase I.

7. Chromosome Separation

Mitosis: During anaphase, sister chromatids separate and begin migrating centromere first toward opposite poles of the cell. A separated sister chromatid becomes known as daughter chromosome and is considered a full chromosome.

Meiosis: Homologous chromosomes migrate toward opposite poles of the cell during anaphase I. Sister chromatids do not separate in anaphase I.

I can add the similarities between them if you need. This work is not mine, I got it from thoughtCo.

Good luck :)

Answer:

The answer is 26.03728. We assume you are converting between grams C2H2 and mole. You can view more details on each measurement unit: molecular weight of C2H2 or mol This compound is also known as Acetylene. The SI base unit for amount of substance is the mole.

Explanation:

The solution is 26.03728. We assume you are converting between grams C2H2 and mole. You could view more information on each size unit: molecular weight of C2H2 or mol This compound is also called Acetylene. The SI base unit for the quantity of the substance is the mole.

The C2H2 molecule is product of sigma-bonds and pi-bonds, with a bond attitude of one hundred eighty ranges. This linear molecular geometry is similar to that of CO2 (Carbon dioxide), which is likewise a non-polar compound.

C2H2 has a linear molecular geometry because all the atoms are symmetrically aligned inside the same aircraft. Both Carbon atoms are inside the centre of the C2H2 Lewis structure due to the fact they may be much less electronegative than Hydrogen atoms.

The chemical formulation for acetylene is C2H2 and the chemical composition for carbon monoxide is CO. There are 2 carbon atoms in every acetylene molecule and 1 carbon atom in every carbon monoxide molecule. In each mol of any chemical substance, there are 6.022*10^23 molecules.

Explanation:

Electrolysis is the process where electricity is used to drive chemical reactions.

In the electrolysis of aqueous solution of sodium chloride, hydrogen gas produces at the cathode which is a negative electrode and chlorine gas produces as the anode which is a positive electrode and the sodium hydroxide remains dissolved in the solution.

The reactions will be :

[tex]NaCl\rightarrow Na^++Cl^-[/tex]

[tex]H_2O\rightarrow H^++OH^-[/tex]

Hence, electrolysis of an aqueous solution of sodium chloride lead to the formation of four ions,[tex]H^+[/tex] , [tex]OH^-[/tex] , [tex]Na^+[/tex] and [tex]Cl^-[/tex]

Explanation:

Of the given options, Lithium (Li) would most readily react with water.  

• The substances that spontaneously go through a chemical reaction with water, as they are highly reducing in nature are known as water reactive substances.  

• The alkali metals and the alkaline earth metals are the metals that reacts the most with water.  

• In the periodic table, the alkali metals, that is, lithium, sodium, potassium, rubidium, caesium, and francium are the most reactive metals.  

• They all react explosively and vigorously with cold water leading to the displacement of hydrogen.  

• The alkaline earth metals are the second most reactive metals in the periodic table apart from Be, which does not react with water.  

Thus, Li is the alkali metal that reacts readily with water.

I'm pretty sure it's false. It is used to measure the amount of Moles in an element.

I'm sorry if this is incorrect.

The Avogadro number is the number of atoms in one mole of a substance. Hence, it can be used to determine the number of atoms, electrons or molecules. Thus, the statement is true.

Any substance containing 6.02 × 10²³ atoms is called one mole of the substance. This number is called Avogadro number. The name came from the scientist Avogadro.

This number measures the number of atoms in specific moles of an element or compound. One mole of a compound contains Avogadro number of molecules.

The mass of an element containing Avogadro number of atoms is called its atomic mass. Similarly, the mass of a compound that contains Avogadro number of molecules, that is one mole of the compound is called its molar mass.

Hence, we can calculate the number of atoms in a given number of moles of an element or compound by knowing that one mole of it contains Avogadro number of atoms.

Answer:

37.1 calories.

Approximately, 37.1 = 40 calories.

Explanation:

So, without mincing words let's dive straight into the solution to the question above.

We are given the following parameters which are going to help in solving this particular Question.

The mass of broccoli = 86g of broccoli, mass of carbohydrates present = 6g of carbohydrates, the mass of protein present = 2.6g of protein and the mass of fat present = 0.3g of fat.

Therefore, the nutritional energy content (in Calories) = (6 × 4) + (2.6 × 4) + (0.3 × 9) = 10.4 + 24 + 2.7 = 37.1

Hence, the nutritional energy content (in Calories) = 37.1 calories.

Approximately, 37.1 = 40 calories.
