Answer:A cell is the smallest unit of life, also called the 'building blocks of life' because cells multiply and differentiate to form a multicellular organism as well as give rise to new organism by forming gametes or reproductive spores.
Explanation:
9) One difference between carbon-12 ( 2C) and
carbon-14 (CO) is that carbon-14 has
A) two more protons than carbon-12.
B) two more clectrons than carbon-12.
C) two more neutrons than carbon-12.
D) A and C only
E) B and C only
Answer:
C
Explanation:
this is because that Carbon 12 has 6 protons and electrons and the same goes for Carbon 14 so Choice A and choice B can't be answers so D and E arent equivalent too that means Choice C can be the appropriate answer.
further more explanation:
it's also Choice C because both carbon atoms are neutral which means that the number of protons and the number of electrons are the same so that leaves us with neutron and we get the neutron number by subtracting the mass number with the proton number so let's go on shall we!
for carbon 12= 12-6=6
for for carbon 14=14-6=8 which means the best alternative is Choice C.
Best of luck!!!

how many organelles are there in a cell. What are their names and what do they do. I am keeping notes
Answer:
Nucleus - controls all activities of the cell
Nucleolus (in the middle of the nucleus)
- the synthesis of ribosomes and RNA (ribonucleic acid)
Mitochondria (battery of cell) - oxidise glucose to release energy in the form of ATP ( adenosine triphosphate)
Edoplasmic reticulum
1. Smooth - synthesises lipids
2. Rough- Transport proteins synthesised by ribosomes
Golgi apparatus ( golgi body, or any golgi, is has many names)
- Acts as Centre for processing, packaging and transporting macromolecules such as proteins and carbohydratez
Ribosomes - sites of protein synthesis
Lysosomes- Break down macromolecules such as proteins, lipids etc
Vacuoles - store food substances, site for waste products
Centrioles - form spindle fibres during cell division
Cytoplasm ( the so call empty spaces in the cell)
- place where biochemical reactions occur
Plasma membrane
-control movement of substances in and out of the cell due to its semi permeable characteristics
Ok that's all for animal cells, but for plants cells, there is more
Cloroplast - site for photosynthesis
Cell wall - Maintains the shape of plant call, give support to cells

Which of the following is a reactant during cellular respiration?
Carbon dioxide
Glucose
Energy
Water
Answer:
Glucose
Explanation:
In the process of cellular respiration, glucose and oxygen combines to produce products such as carbon dioxide and water.
Reactant+ Reactant= Product.
Glucose (Reactant)+ Oxygen (Reactant)= Carbon Dioxide (Product) and Water (Product) (C02)
Hope this helps!
The one that is a reactant during cellular respiration is Glucose. The correct option is B.
What is cellular respiration?Cellular respiration is a process of breakdown of food material to produce energy that is then saved in the form of ATP. The process occurs when oxygen is combined with food and produces energy and reduces the waste material removed from the body.
The chemical process includes four processes that occur in sequence to carry out the whole process. The processes are glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
All food that we eat gives us different macromolecules, glucose is the main source of energy. So glucose is converted into energy.
Thus, the correct option is B. Glucose.

Fracking uses highly pressurized fluids, such as water mixed with sand and chemicals, to drive open cracks that exist in underground rock. Which statement best describes an environmental consequence of this process?
A. Chemicals added to the liquid can contaminate groundwater.
B. Wastewater is contaminated with oil and becomes sludge in landfills.
C. Water vapor is released into the air, which is considered a greenhouse gas.
D. Heavy metals are released into surrounding soil, poisoning local vegetation.
Answer:
Option A, Chemicals added to the liquid can contaminate groundwater, this statement best describes an environmental consequence of this process.
Explanation:
Fracking is a process of digging fossil energy sources, which need a lot of water and uses local water resources. It is drawn with high-pressure water, sand and elements, creating high pressure to block the porous rock and discharge gas. The spill itself stops energy from the drilling position, and may even make earthquakes, mainly due to the pumping of overflowing wastewater into porous rock types such as limestone. The most significant result of water distortion is on groundwater.To learn more about fracking, refer:

Answer:
[tex]{ \underline{ \sf{true}}}[/tex]
Explanation:
because they chemically decompose
It is true that inorganic compounds include carbon dioxide, oxygen, water, and most ionic compounds.
What are inorganic compounds?Any substance in which two or more chemical elements usually other than carbon are combined, almost always in definite proportions, is an inorganic compound.
When carbon is bound to hydrogen, the compound is classified as organic.
Organic compounds are distinguished by the presence of carbon atoms. Most inorganic compounds do not contain carbon atoms.
Water, sodium chloride (salt), sodium bicarbonate (baking soda), calcium carbonate (dietary calcium source), and muriatic acid are examples of common inorganic compounds (industrial-grade hydrochloric acid).
Inorganic compounds are characterized by high melting points and varying degrees of electrical conductivity.
Thus, the given statement is true.

essay on atoms molecules and matter
Answer:
Atoms are typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the center of the system. The electrons orbit this nucleus, like planets. If atoms are impossibly small, these subatomic particles are even more so.
Molecules are groups of atoms clumped together by chemical bonds. They are also distinguished from ions by their lack of electrical charge.
H20 is a molecule, N2 is a molecule even O3 is a molecule.
Matter is basically anything that takes up space and that has mass. All physical objects have matter. The original stated of matter are solid, Liquid, And gas.
