Definition: Asexual reproduction is a type of reproduction which does not involve the fusion of gametes or change in the number of chromosomes. The offspring that arise by asexual reproduction from a single cell or from a multicellular organism inherit the genes of that parent.
Types:
Budding- A form of asexual reproduction of yeast in which a new cell grows out of the body of a parent.
Vegetative Reproduction- Plants budding which creates a runner hich sends a clone
Strawberries plants
Dandelion
Parthenogenesis- An unfertilized egg develops into an adult (Aphids, honeybees, lizards)
Binary Fission- One cell splits into two cells
Allows for no genetic variety
Bacteria performs it
Protests perform it but takes longer
Regeneration- The ability to regrow a missing part of the body by Mitosis
Fragmentation- A small piece of an organism breaks away from it and develops into a new individual (star fish)
Spores- Contain DNA, cytoplasm, and tough putter wall protects it from dying out produced by many organisms (algae, fungi, bacteria)
Advantages: Allows rapid populating, does not need mates, does not require mobility, friendly to the environment, handy in case of emergency.
Disadvantage: poses some inheritance issues, can lead organism to being prude to extinction, carries problems with population control, causes organism to not be able to adapt and results in poor conditions to subject
Answer:
oxalate, fluoride, carbonate, phosphate.
Explanation:
It is important to consult the solubility chart in order to determine the anions.
Any compound with a low Ksp means the compound is very insoluble.
Hence, it means the formation of this compound is favoured strongly and its dissolution which would liberate calcium ions is unfavoured.
Any compound with a low Ksp would therefore "soak up" all the free calcium and will thus not be present in the solution.
Using solubility chart and noting the compounds with a low Ksp value, the anions that are probably present are: oxalate, fluoride, carbonate, phosphate.
Answer:
D) Neon and argon, because they are both noble gases

Answer:
The coefficient of O2 is 11
Explanation:
Step 1:
The equation for the reaction:
FeS2 + O2 → SO2 + Fe2O3
Step 2:
Balancing the equation. The equation can be balance as follow:
FeS2 + O2 → SO2 + Fe2O3
There are 2 atoms of Fe on the right side and 1 atom on the left. It can be balance by putting 2 in front of FeS2 as shown below:
2FeS2 + O2 → SO2 + Fe2O3
There are 4 atoms of S on the left side and 1 atom on the right side. It can be balance by putting 4 in front of SO2 as shown below:
2FeS2 + O2 → 4SO2 + Fe2O3
Now, there are a total of 11 atoms of O on the right side and 2 atoms on the left side. It can be balance by putting 11/2 in front of O2 as shown below:
2FeS2 + 11/2O2 → 4SO2 + Fe2O3
Multiply through by 2 to clear the fraction as shown below:
4FeS2 + 11O2 → 8SO2 + 2Fe2O3
Now the equation is balanced.
The coefficient of O2 is 11
