A student redid the experiment of mixing room-temperature water and warm
water. This time, she doubled the amount of room temp water. How will the final
temperature be different?
A- It will be higher, because the amount of water in the mixture is greater.
B-It will be lower, because the temperature of the room-temperature water will not increase as much.
C-It will be the same because all parts of the mixture will end up at the same temperature.
D-It will be higher, because all parts of the mixture will end up at the same temperature.

Answers

Answer 1

a single cell undergoes mitosis every five minutes how many cells will result from this cell in 20 minutes

Answers

Answer:

= 16 cells

Explanation:

Mitosis is the stage of cell division in nonsexual cells of eukaryotic organisms (that is, cells that have a nucleus). It takes place in several phases, begins after DNA duplication and ends with the separation of the two daughter cells.

It is a fundamental mechanism that occurs for the first time in the hours following fertilization.

After duplication of the genetic material, during interphase, it condenses and groups to form chromosomes with two genetically identical chromatids: this is the prophase. The nuclear membrane then dislocates, and the centromeres of the chromosomes (the area where the two chromatids of the same chromosome overlap) bind to the microtubules via the kinetochores. Gradually, all the chromosomes are sequestered at the equator of the cell: this is the metaphase.

Then, during anaphase, the chromosomes will split into two chromatids, each of which is pulled towards a pole of the cell. Thus, at each top of the cell, there is a copy of each chromosome. During telophase, the nuclear envelope will begin to reform around the set of chromosomes as the DNA gradually decondensed. The plasma membrane invaginates equatorially under the action of a ring of myosin and actin. Increasingly narrow, the bridge between the cells eventually breaks, and two cells are formed as a result of cytodieresis. Each of them can resume their growth.

Now; having understood what Mitosis is all about.

When a single cell undergoes mitosis every 5 minutes; we have the formation of two daughter cells.

Then in 20 minutes; we will have:

Explain the difference between potential energy and kinetic energy.



Sentence Starters

"Potential Energy is. . "

"Kinetic Energy is. . "

"The difference between potential energy and kinetic energy is. . ."

Answers

Answer:

Potential energy is the stored energy in an object or thing, while kinetic energy is the energy which an object contains because of a particular motion.

Explanation:

Potential energy is energy that is stored for example a wind up toy, it has energy but in order for you to get kinetic energy, it has to move. So kinetic energy is moving energy.

The difference is that potential is stored and kinetic is moving energy.

2- In the series circuit, different voltage exists across each component in the circuit. Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.

3- The equivalent resistance in case of a series circuit is always more than the highest value of resistance in the series connection. While the equivalent resistance in the parallel circuit is always less than any of the individual resistances in parallel combination.

4- A fault in one of the components of the series circuit causes hindrance in the operation of a complete circuit. As against fault in a single component in a parallel network do not hinder the functioning of another part of the circuit.

The detection of a fault in case of a series circuit is difficult, but it is quite easy in parallel circuits.

B. A molecule with symmetrical nonpolar covalent bonds

C. A molecule with a negative pole and a positive pole

D. A molecule with two atoms of the same electronegativity

Answers

Explanation:

A molecule with a negative pole and a positive pole is called a polar molecule.

(d) A molecule with two atoms of the same electronegativity

What is meant by a polar molecule?

 A polar molecule is usually formed when the one end of the molecule is said to possess more positive charges and whereas the opposite end of the molecule has negative charges, creating an electrical pole.

What is a polar molecule example? Water (H2O) is a polar molecule. The bonds between hydrogen and oxygen are distributed so that the hydrogen atoms are both on one side of the oxygen atom rather than evenly spaced.Sodium Chloride (NaCl) which is an ionic compound acts as a polar molecule. Usually, the large difference in electronegativities in sodium and chlorine makes their bond polar.

Answers

Answer:

The correct option is;

Element 2

Explanation:

The ionization energy is the energy required to eject an electron from a gaseous ion or atom

The ionization energy increases across the period and increases up the group

The elements with the highest ionization energy are those that have the complete octet structure in their outermost shell, which are the noble gases

Therefore, given that element 2, which has the complete octet structure in the outermost shell, then it is an element of the noble gases which have the highest ionization energy in a period, and therefore has the highest ionization energy.

On the periodic table, the element with 10 electrons is Neon, with ionization energy of 2080.68 kJ/mol which is the second highest after helium, that has only 2 electrons.

You are an employee at "cash for gold" and a customer comes in looking to exchange gold for money. They claim to have 3.47 gram nugget of fold. How many particles (atoms) of gold are in one nugget? With work shown

Answers

Answer:

The number of atoms in 3.47 gram nugget of gold is approximately 1.0606 × 10²² atoms

Explanation:

The given mass of gold = 3.47 grams

The molar mass of gold = 196.96657 g/mol

The number of moles of gold in 3.47 grams of gold = 3.47 grams/(196.96657 g/mol)

The number of moles of gold in 3.47 gram nugget of gold = 0.01762 moles

The number of atoms in one mole of gold = 6.02 × 10²³ atoms

The number of atoms in 0.01762 moles of gold = 6.02 × 10²³ atoms/mole × 0.01762 moles

The number of atoms in 0.01762 moles of gold ≈ 1.0606 × 10²² atoms

∴ The number of atoms in 3.47 gram nugget of gold ≈ 1.0606 × 10²² atoms.
