Answer:
Animal Cell Cytokinesis
Explanation:
Answer: Animal cell
Explanation:) It refers to the process of cell division, which takes place during mitosis, is known as cytokinesis.
The process of cytokinesis is different for animal cell and plant cell.
Where, in case of plant cell, a separation, known as cell plate is formed along the center of the parent cell, which is responsible for the separation of the cells.
Whereas, in case of animal cell, the plasma membrane contracts itself along the center, until the two daughter cells are separated from each other.
Hence, from the given information of the question,
The correct answer is animal cell.
In a single molecule of water, two hydrogen atoms are bonded to a single oxygen atom by _____.
A) hydrogen bonds
B) nonpolar covalent bonds
C) polar covalent bonds
D) ionic bonds
Answer:
C) polar covalent bonds
Explanation:
Polar covalent bonding can be regarded as a chemical bond that involves a pair of electrons which is
unequally shared between two atoms.
The electron are not shared equally as a result of one of the atom spending more time with the electron compare with the other atom. It is one whereby atoms having different electronegativities involves themselves in sharing electrons in a covalent bond

Explain what you discovered from the Simulation about why food coloring spreads faster in warmer water.
Answer:
The food colouring mixes through the hot water faster than it mixes with the cold water, this is because in hot water the water molecule have more energy and are moving faster than the molecules of cold water .This makes it easier for the food colouring to get mixed quickly through the hot water.

Determine the correct set-up below to determine what mass, in grams, of N2 is needed to completely react with 105 g F2 ?
Answer:
C: 1 mol F2/38 g F2
Explanation:
The reaction equation is;
N2 + 3F2 = 2NF3
Now, to know how many grams, of N2 is needed to completely react with 105 g F2 and since the molar mass of N2 is 28.02 g/mol, Molar mass of F2 is 38 g/mol, number of moles attached to N2 and F2 in the reaction are 1 and 3 moles respectively, then we will have;
105 g F2 × 1 mol F2/38 g F2 × 1 mol N2/3 mol F2 × 28.02 g N2/1 mol N2
Option C is Thus correct

What is the molecular formula for a compound that is 34.31% sodium, 17.93% carbon, 47.76% oxygen and has a molar mass of 134.00g?
Answer: Na2C2O4 probably sodium oxalate
Explanation: assume you have 100 g substance.
Mass of Na is m(Na) = 34.31 g, m(C) = 17.93 g and m(O) = 47.76 g.
Calculate moles n(Na) = 34.31 g/22.99 g/mol= 1.49 mol.
For C n(C) = 1.49 mol and n(O) = 2.985. You divide all by 1.49 you
Get n(Na) : n(C) : n(O) = 1:1:2 M(NaCO2) = 67 g/mol.
Divide 134:67 = 2. You get formula Na2C2O4

According to ideal gas equation, there are 271472.7 moles of gas present in a gas trapped within a 37.0 L vessel at 80.0°C at a pressure of 2.50 atm.
What is mole?Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.
It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.
It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons .Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.
Substitution of values in ideal gas equation gives,n= 2.5×37/8.314×353=271472.7 moles.

List and Describe the two groups of clastic sedimentary rock.
Answer:
Clastic sedimentary rocks are formed from rock fragments or clasts; chemical sedimentary rocks precipitate from fluids, and biochemical sedimentary rocks form as precipitation from living organisms.
Sedimentary rock is classified into two groups based on how they form. They are clastic and chemical. Clastic sedimentary rock is formed as bits of weathered rock become cemented together. Because all kinds of rock are subject to weathering many different minerals can make up this group of rocks.

What drives the flow of energy in cycling of matter in the atmosphere
if water is added to a 0.70 molar solution of CuSO4 what will change
A. molarity will increase
B. Molarity will decrease
C. the amount of CuSO4 will decrease
D. No change in molarity or amount of salute
Answer:
B. Molarity will decrease
Explanation:
Molarity is one of the measures of the molar concentration of a solution. It is calculated by dividing the number of moles of the solute by the volume of the solvent. This means that the higher the amount of solute in relation to the volume of solvent, the higher the molarity of that solution.
In essence, adding water to a solution dilutes it i.e it increases the solvent's volume in relation to the solute, causing the molarity to decrease. In a nutshell, diluting a solution (by adding water or more solvent) causes the molarity of such solution to decrease. For example, if water is added to a 0.70 molar solution of CuSO4, the molarity of the solution will DECREASE.

A solution of 1.8274g of a polypeptide in 274mL of a aqueous solution has an osmotic pressure at 31.40 degrees C of 2.012 mmHg. The approximate molecular weight of this polymer is _____ g/mol.
Answer: Hence, the approximate molecular weight of the poymer is 64106 g/mol
Explanation:
[tex]\pi=CRT[/tex]
where,
[tex]\pi[/tex] = osmotic pressure of the solution = 2.012 mm Hg = 0.0026 atm
i = Van't hoff factor = 1 (for non-electrolytes)
Mass of solute (polypeptide) = 1.8274 g
Volume of solution = 274 mL
R = Gas constant = [tex]0.0821Latm/Kmol[/tex]
T = temperature of the solution = [tex]31.40^0C=(273+31.40)K=304.4K[/tex]
Putting values in above equation, we get:
[tex]0.0026=\frac{1.8274 g\times 1000}{M\times 274ml}\times 0.0821\times 304.4[/tex]
[tex]M=64106g/mol[/tex]
Hence, the approximate molecular weight of the poymer is 64106 g/mol

Facts about flooding
Answer:
No region is safe from flooding. All 50 states are subject to flash floods.[1]
Flash floods can bring walls of water from 10 to 20 feet high.[2]
A car can be taken away in as little as 2 feet of water.[3]
To stay safe during a flood, go to the highest ground of floor possible. If your skin comes in contact with flood water, make sure to wash it with soap and disinfected water because the contents are unknown.[4]
Flooding is caused by spring thawing (snow and frozen grounds melting in the spring), heavy rains, snow melt runoffs, flash floods, and mudflows.[5]
Floods are the most widespread natural disaster aside from wildfires. 90% of all U.S. natural disasters declared by the President involve some sort of flooding.[6]
In preparation for a flood, it is important to stock up on first aid items, non-perishable foods, 3 gallons of water per person for 3 days, battery operated radio for weather reports, extra batteries, personal hygiene necessities.[7]
Based on Floodsmart, a 2,000 square foot home undergoing 12” of water damage could cost more than $50,000.[8]
Since flood damage is almost never covered by homeowners insurance, flood insurance is important for people living in high-risk flood zones.[9]
To stay safe during a flood, go to the highest ground of floor possible. If your skin comes in contact with flood water, make sure to wash it with soap and disinfected water because the contents are unknown.[10]
Communities particularly at risk are those located in low-lying areas, near water, or downstream from a dam.[11]
