Answer:
Energy should be saved and controlled as it is better for the environment. Excess use of energy of any kind can be disastrous. For example, a kind of energy is stored in the food. If excess food is consumed and wasted, then the country and other people will have to face consequences of it. Malnutrition will rise.
Another kind of energy is the energy in the fuel. If fuel consumption is not controlled then in the near future the resources for the making of fuel will be depleted.
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:
21
Explanation:
Let us count the number of individual atoms for Na2S2O3 (the compound name):
Na: 2
S: 2
O: 3
This brings us to a total of 7 atoms for one molecule of sodium thiosulfate. For three of these compounds, we get 3*7=21
Answer:
Explanation: Bromine, the dark red color disappears quickly as the atoms of bromine bond with the atoms of carbon in the double bond.
Answer : The correct option is, (C)
Explanation :
A.
This is synthesis reaction in which the two or more reactant react to give a single product.
B.
This is combination reaction in which the two reactants combine to form a single product.
C.
This is a neutralization reaction in which an acid react with a base to give a salt and water as a product.
D.
This is a double displacement reaction in which the positive cation and negative anion of two reactants exchange their places to give two new products.
Hence, the reaction (C) is a neutralization reaction.
