Answer:
made of different kinds of tissues
Explanation:
cause that's the only one that makes sense because it goes: cell, tissues,organ,organ system , organism
1. the simplest unit of life - cell
2. a individual organ - would be made of different kinds of tissues
3. tissues - would be made of one kind of cell
4- an organ system - meets all the needs of a organism
also it wouldn't make sense for a individual organ to be made of only one kind of cell so yeah
good luck :) I hope this was right
H2SO4 + 2NaOH → Na2SO4 + 2H2O what volume of water vapor will be produced if you start with 71.5 g of sulfuric acid and excess of sodium hydroxide
Answer:
Explanation:
Find the molar mass of H2SO4
2H = 2 * 1 = 2
S = 1 * 32 =32
O4 = 4*16 = 64
total 98
Find the number of mols in 71.5 grams
mols = given mass / molar mass.
given mass = 71.5
molar mass = 98
mols = 71.5/98
mols = 0.7296 mols of H2SO4
Find the moles of H2O
From the Balanced equation, every mol of H2SO4 produces 2 moles of H2O
mols water = 2 * 0.7296
mols water = 1.4592
That's as far as I can take you. I have to know a great deal more to get the volume of H2O

However, in day-to-day experience, the strangeness of Einstein's ideas doesn't help us, and Newton's notions do just fine. In everyday Life, when gravity isn't especially intense, Newton's and Einstein's ways of thinking lead to similar results.

molecular mass meaning in chemistry?
Answer:
Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.
Explanation:
The molecular mass gives the mass of a molecule relative to that of the 12 C atom, which is taken to have a mass of 12. Hence why Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.

5 Facts about cell division
Answer:
Cell division is the process by which a cell, called the parent cell, divides into two cells, called daughter cells.[1] When the cell divides, everything inside it divides also. The nucleus and the chromosomes divide, and the mitochondria divide also.
In mitosis, an ordinary body (somatic) cell divides to make two daughter cells.
In meiosis, a cell divides twice, to produce four gametes (sex cells). The first division of meiosis is a special kind of cell division called a reduction division because the number of chromosomes is halved. The second division of meiosis is similar to mitosis.[2]
Three types of cell division: left is binary fission as in bacteria; right are mitosis and meiosis as in eukaryotes.
Cells are the 'building blocks' of life, and cell division is a basic feature of life. For simple unicellular organisms like Amoebozoa, one cell division reproduces the entire organism. On a larger scale, cell division can create offspring from multicellular organisms, such as plants that grow from cuttings. But most importantly, cell division enables organisms that are able to sexually reproduce to develop from the one-celled fertilised egg (zygote). Cell division also allows for continual renewal and repair of the organism.
The cell division is completed in the four phases prophase, metaphase, anaphase, and telophase.
What is cell division?It is the process by which cells divide into daughter cells. This keeps the cell organism to survive.
The five facts about cell division are:
The cell division has 4 phases.In prophase, the cell DNA condensed to form chromosomes.In metaphase, the chromosomes are aligned in the middle of the cell.In anaphase, the chromosomes move towards the different poles.In telophase cells divide into two daughter cells.Therefore, the cell division is completed in the four phases prophase, metaphase, anaphase, and telophase.

Look at the following enthalpy diagram. Select all that apply.
1. The products have more energy than the reactants.
2. This is an addition reaction.
3. A large activation energy is required for this reaction to take place.
4.The products are more stable than the reactants.
5. This is a substitution reaction.
Answer:
Option 2 and 4 are correct
Explanation:
The reactants in the attached image have more enthalpy and hence less stability as they are more reactive. Thus, Product is more stable than the reactants.
This is an addition reaction in which two reactants add up to form the product.
Very less activation energy is required as the reactants themselves are unstable, possess high energy and hence are very reactive.
Reactants have more energy than the products.

22 Determine the molar mass of an unknown gas that has a volume of 72.5 mL at a temperature of 68C, and a pressure of 0.980 atm and a mass of 0.207 g.
Answer:
81.5g/mol
Explanation:
Molar mass is the ratio between mass of a substance (In this case, 0.207g) and moles presents in this mass.
To solve this question we must find the moles of the gas in order to obtain the molar mass using:
PV = nRT
PV / RT = n
Where P is pressure = 0.980atm
V is volume in Liters = 0.0725L
R is gas constant = 0.082atmL/molK
T is absolute temperature = 68°C + 273.15 = 341.15K
0.980atm*0.0725L / 0.082atmL/molK*341.15K = n
2.54x10⁻³ moles = n
Thus, the molar mass of the gas is:
0.207g / 2.54x10⁻³ moles

How body systems work together?Your digestive tract takes nutrients and water from the food you eat in to your body. The body's cells receive oxygen, water, and nutrients through your circulatory system.
Your skin, excretory system, and respiratory system all function to remove wastes from your cells.
Your body's many systems depend on one another to function properly. While your heart's muscles require oxygen from your lungs to beat, your respiratory system depends on your circulatory system to distribute the oxygen it collects.
Therefore, option B is correct.

Explanation:
Answer:
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart.
