During photosynthesis, plant cells use sunlight as an energy source; animal cells cannot do this. What substance do Animal cells lack,that allows plant cells to carry out photosynthesis?(SC.8. L.18.1)a.ATPb.Carbon Dioxide. Chlorophyll. Oxygen
Answer:
Chlorophyll
Explanation:
Photosynthesis is the process through which plant cells use carbon dioxide & water to create oxygen & energy rich organic compounds. They do so by converting sunlight ie light energy into chemical energy. This is possible due to presence of chlorophyll in them. Animals can't do so, as they dont have chlorophyll.

Answer:
HEAT VS TEMPERATURE
Heat and temperature are related but they are not the same. Heat depends on (1) how fast molecules vibrate and also on (2) the number of molecules that vibrate. More vibrating molecules usually mean (3) more internal energy. Fewer vibrating molecules usually mean (4) less internal energy. Faster vibrating molecules mean (5) higher temperature. Slower vibrating molecules mean (6) lower temperature. Heat is measured in units called (7) Joules and (8) calories. Temperature is measured in units called (9) Celsius, (10) Fahrenheit, and (11) kelvin. When matter is heated, it (12) expands
Explanation:
The atoms and molecules of a substance to which heat is added vibrate faster. The vibration of the atoms causes the space between the atoms to increase. The state of the matter, liquid solid or gas is determined by the motion and spacing of the particles in the matter.
As the motion of the of the molecules in the substance increases, the substance expands.

What are some similarities between atoms, molecules, and elements?
Answer:
Physical matter is made up of atoms and molecules. An atom is the sub-component of a molecule, or the smallest unit of matter. It is the smallest part an element can divide into. A molecule is made up of atoms that are bound by ionic, covalent or metallic bond.
Aliyah marks a line on her driveway with a piece of chalk and another line 50ft away Then she stands with both feet at the line and runs to the opposite line While she runs she times how long it takes her to get to the other line What is she trying to find with the distance and time
Answer:
Speed
Explanation:
Aliyah must have been trying to find her speed.
The speed is a measure of how fast an object or a body is and it is calculated by finding the ratio of distance with time. Mathematically,
speed = [tex]\frac{distance}{time}[/tex] with a unit of m/s.
Hence, with the distance measured on the ground and Aliyah trying to find the time it will take her to cover the distance while running, she must have been trying to find how fast she can run, that is, speed.
A scientist discovers a new substance. The molecules of the substance form hydrogen bonds with each other. When the molecules lose a lot of
energy, the hydrogen bonds hold them relatively far apart. Based on this information, what can the scientist infer about the substance? (2

It expands when it freezes.
Oь
It is highly colored.
Ос
It exists only as a gas.
Od
It does not dissolve ionic compounds.
Answer: The answer is: It expands when it freezes. When molecule freezes, it lose energy. When molecules are far apart, it means the volume is greater and it expands.

What is the boiling point in °C) of a 0.527 m
aqueous solution of LiBr?
Enter your rounded answer with
3 decimal places.
To solve this we must know the concept behind the phenomenon of elevation in boiling point when a non volatile solute is added to any solvent. Therefore, boiling point in °C of a 0.527 m aqueous solution of LiBr is 100.54 °C.
What is elevation in boiling point ?Whenever a non volatile solute is added to a solvent then the boiling point of solvent increases.
Mathematically,
ΔT= Kb× molality
The complete balanced equation can be written as
LiBr → Li⁺ + Br⁻ [two ions]
substituting all the given values in the above mathematical expression, we get
(0.527 m LiBr) x (2 mol ions / 1 mol LiBr) = 1.054 m ions
(0.512 °C/m) x (1.054 m) = 0.540 °C change
100.00°C + 0.540 °C = 100.54 °C
Therefore, boiling point in °C of a 0.527 m aqueous solution of LiBr is 100.54 °C.

Which of the following statements best describes what will happen when white light hits a red object? hits a red object?
Question 3 options:
All wavelengths of the light are reflected.
Red wavelengths are reflected while all others are absorbed.
All wavelengths of the light are absorbed.
Red wavelengths are absorbed while all others are reflected.
When white light hit a red colored object, all colors are absorbed and only red color is reflected. Hence, the object appears red in white light.
What is light reflection ?When a light ray hit a transparent or translucent object after hitting the surface the light ray will radiate back in a straight line and make the object's surface gleaming. This is called reflection.
The white light is a mix of all colors. White light absorbs all colors and reflect all colors as well and appears as white. Whereas, all other colors absorbs all colors but reflects only a particular wavelength and appear in the reflected color.
Red light is the longest wavelength among VIBGYOR. It absorbs all wavelengths but reflect only red light. Hence, it will appear in red in all light. Thus, option b is correct.

D. Adding more of the chemical will heat the water but only up to a certain temperature
Further explanationChemical changes are changes in the process that produce new substances that are different from the initial/ forming substances. Chemical changes are usually known as chemical reactions. So there are products/reactions and reactants and there is a change in the molecule/particle
The chemical reaction is usually followed by the release of heat, gas, change in color, precipitate substance etc
The heat that occurs in the addition of chemicals is caused by the reaction with water. But there is a constant rise in temperature when water reaches its maximum capacity to react with these chemicals.
Evidenced by the addition of 15 g and 20 g of chemicals, the temperature changes are constant

One step in the industrial production of nitric acid is the reaction of ammonia with oxygen gas. 4NH3(g)+5O2(g)-->4NO(g)+6H2O(g) What is the volume of nitrogen monoxide gas that can be produced from 8L of oxygen gas.
Answer:
Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas
Explanation:
Equation of reaction: 4NH₃(g) + 5O₂(g) --> 4NO(g) + 6H₂O(g)
From the equation of reaction, 5 moles of oxygen gas produces 4 moles of nitrogen monoxide gas
1 mole of a gas at STP occupies a volume of 22.4 L
5 moles of oxygen gas occupies a volume of 5 * 22.4 L = 112 L
4 moles of nitrogen monoxide as occupies a volume of 4 * 22.4 L = 89.6 L
Therefore, 89.6 L of nitrogen monoxide gas are produced from 112.0 L of oxygen
Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 8.0 * (89.6/112
Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas
3(so)4 how many sulfur atoms and oxygen
Answer:
There is 3 sulfur and 12 oxygen atoms
To see the number of atoms of an element in a given molecule we need to multiply stoichiometry to the number that is written on the foot of the element that is stoichiometry. Therefore, in 3(SO)[tex]_4[/tex], there are 3 sulfur atom and 12 atoms of oxygen.
What is atom?Atom is the smallest particle of any element, molecule or compound. Atom can not be further divided. Atoms contains nucleus in its center and electron that revolve around the atom in fixed orbit.
In the nucleus, proton and neutron are present. Electron has -1 charge while proton has +1 charge. Neutron is neutral that is it has no charge. So overall the charge of nucleus is due to only proton, not by neutron. In 3(SO)[tex]_4[/tex], there are 3 sulfur atom and 12 atoms of oxygen.

Answer:
i think option b
C 1 and 3
Explanation:
Simple distillation is a method for separating the solvent from a solution. For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates.
Crystals grow because salt molecules in the solution meet up and interlock. As they do so, they fit together like puzzle pieces, arranging themselves in a lattice structure, thus creating a crystal nucleus. ... it crystallizes.
